General Information
Land warrior is not a single unit, but a system, spread out among multiple units, and integrated directly into ground vehicles, aircraft, and soldier's armor. Intended predominately to provide intelligence to the user, the system allows for easier control and access to sophisticated smart technology present, and to offer these capabilities on every level of the battlefield. The system not only provides soldiers with information, but commanders and other soldiers with information about them. From heart rate, to breathing, to general medical information, and updated information in the field, the system serves to integrate up to date information and rapid access to the field and commanders, to provide a method of interaction in both tactical and strategic never seen before without these installations. The soldier now has access to all or most of the basic command and radio communications (assuming someone on their channel is hooked up to a primary radio system, which is of course transferred to a minor radio system). The user can either access various verbal radio channels or text based radio channels, in order to minimize their input of verbal sounds and prevent "Helmet Fire". This is hooked up to the EPLRS system, and allows near real time information on secure, jam free channels for quick available tactical data. It also has a GPS based IDFF "Identification friend or foe" system, that allows user to see relative distances between individuals with the GPS system on a motion tracker like grid, and as well as see their teammates relative positions on a map in a zoomable and outzoomable positions, with an appearance similar to google maps. This information can be relayed to various other units, such as mobile vehicles and aircraft, as well as command centers, to give a ,more accurate layout to commanders and support units, to prevent fire from assisted attacks other than infantry as well. All the information is hooked up the Liquid crystal display in the facemask, allowing for an uplink of the round counter, scope, text based radio chatter, notice on active radio channels, view of the volume of the radio, time (date, time of day, etc.), and GPS based map with the position of friendly units (with the GPS motion tracking devices active on their person or vehicle) and geographic area of the terrain. This can all be controlled by the neural computer interface, providing hands off control of all the system's computer capabilities. The device also possess the ability for customization, allowing the user view of all of the applications at varying degrees of transparency, and at any position on the HUD. The device also can be completely turned off, providing complete and clear view through the facemask. The entire unit weighs approximately 10-15 pounds, although in conjunction with armor it can be lighter, the armor replacing some of the support functions of the device (such as the case for the battery or the head's up display). The individual soldier system also has an estimated cost of around 15,000 dollars. Scope- The scope is essentially a low profile 4-10x zoom 60mm thermal scope design to be attached to standard picatinny rails. It is a low profile scope, with a rail on top of it, similiar to that of the G36; the picatinny rails rest on top of the scope, where iron sights are then placed on top. The rail then extends out on top of the scope, and the iron sights raise up above the scope, to provide accurate fire. A small circular plastic hole allows for view through the support structure for the raised iron sights. Thus, the iron sights are on top of the scope, providing both for combat. In addition, an additional scope can be mounted in front of the thermal scope to provide additional vision increase. The two scopes can be stacked Round Counter- The round counter is a device that is essentially designed to count the amount of rounds fired by the user, and document and log specific information about the rounds fired, including time, firing patterns, and volume. The device is based off of the Black Box, and can either be placed inside of the pistol grip of the weapon, the stock, or placed inside the receiver. The round counter is connected to the Land Warrior system, and allows for the user to see the amounts of round fired and remaining in their magazine, and if programmed correctly, their entire pack. While this can be displayed on the helmet, it is also possible to display on the weapon, with an LCD device. Overall simple in construction, it can only provide a limited degree of information based on the accuracy of the information input by the user, however this makes it consume less energy and be more durable. Laser range finder- The weapon utilizes a laser range finder with a range of up to 2KM, present on the weapon. The device can be utilized to measure the speeds of the target and find it's distance. The device uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the target and returned to the sender. Due to the high speed of light, this technique is not appropriate for high precision sub-millimeter measurements, where triangulation and other techniques are often used. This is similiar to the AN/GVS-5 laser range finder. The same device can also be used to emit an ordinary infrared laser. This can be utilized with a thermal scope in order to see the laser, but keep it hidden from enemy view. This focuses as an ordinary laser sight, although it has a longer range and it hidden from enemy view, provided they don't have thermal vision. Neural Interface- The system is a non-invasive neural uplink to the land warrior system and is based off of the EPOC nueroheadset. The device uses 14 saline sensors for optimal positioning for accurate spatial resolution, while the integrated gyroscope generates optimal positional information for cursor and camera controls. The high performance wireless up-link gives users a total range of motion, although it can be hooked to any device through the use of wires. The device is USB compatible and requires no custom drivers. The device allows for simple cursor moving as well as basic key commands. In addition, the device comes with automated programmable key commands, allowing easily customizable "quick commands" that the user can exploit for a much faster use of the available technology. The device can operate at the speed of the user's thoughts, allowing them to control their electronic uplink much faster in a hand off's environment. This device is also hooked up to the scope allowing for a much quicker zoom feature and is hooked up to the radio commands to allow quick, hands off text communication. Processing core- The processing core of the unit is a highly modified Apple 6 iphone based computer system. The A6 is said to use a 1.3 GHz custom Apple-designed ARMv7 based dual-core CPU, called Swift, rather than a licensed CPU from ARM like in previous designs, and an integrated triple-core PowerVR SGX 543MP3 graphics processing unit (GPU). The A6 chip also incorporates 1GB of LPDDR2-1066 RAM compared to 512MB of LPDDR2-800 RAM in the iPhone 4S providing double the memory capacity while increasing the theoretical memory bandwidth from 6.4 GB/s to 8.5 GB/s. Manufactured by Samsung on a High-κ metal gate (HKMG) 32 nm process, the chip is 96.71 mm2 large which is 22% smaller than the A5 and it consumes less power than its predecessor. Information is scarce but the Swift core uses a new tweaked instruction set, ARMv7s, featuring some elements of the ARM Cortex-A15 such as support for the Advanced SIMD v2, and VFPv4. Analysis suggests that the Swift core has a triple-wide frontend and two FPUs, compared to a two-wide core with a single FPU in the Cortex-A9 based predecessor. A version of the A6 with higher frequency and four graphic cores is called Apple A6X and is found in the fourth generation iPad. The device however, utilizes graphene transistors, a material with the best computation speed present in miniaturized electronics. A nano engineered material, it is capable of speeds up to 100 ghz, and thus is substantially faster than standard civilian processing units. Further more, these units are substantially more durable, having operating temperatures in the thousands of degrees and being 200 times stronger than steel. Combined with this, the system can operate at much higher speeds and has a much longer life over the standard armscale devices. It possesses nearly a terabyte of information storage, stored on an SSD, which is significantly faster, more durable, and smaller than a standard hard drive. It primarily allows for faster reading and writing of information, as well as no chance of fragmentation when doing so, but is generally more expensive. Unlike the iphone, it's connected to a substantially larger battery, and thus can last much longer. As well, it has a liquid cooled radiator as a cooling device, which allows it to operate in a wide variety of conditions, and gives it the ability to overclock without destroying itself. In addition, the device is specialized to work with a modified version of linux, of which the program is written in. It utilizes a slightly different version of the computing system, as to make it difficult for commercial devices to interact with it, therefore making it harder to hack or infiltrate. GPS- A standard GPS is added to fit on the utility belt or in a pocket of the suit. The GPS has a rail attachment, so that it may be added to the gun and removed with relative ease. The GPS can send out both a broadcasting signal, or a small screen can be presented to present the position of the unit. Essentially, the GPS provides a map and a locations device, allowing the user to see the layout of the area through the screen. In addition to this, the gps may be hooked up with the land warrior system or to a scope. Usually, however, it is placed next to the computer device on the back of the suit, where the majority of components are housed. Radio-frequency identification- The radio frequency identification chips are plugged into the armor, usually the soldier, to allow the easy identification of friendly troops without GPS positioning. These provide valuable information, ranging from name, rank, current position, and even medical information. The device is essentially an active Active Reader Passive Tag (ARPT) system (if the batteries wear our), and An Active Reader Active Tag (ARAT) which uses active tags awoken with an interrogator signal from the active reader, with battery assistance. They're mil spec design with a particularly owned frequency, that has a range of 2000 feet. While these do not provide global positioning, they do provide more accurate readings and local readings if the GPS systems go out or are unable to work due to dense foliage or cover (such as in a building). More powerful radios can be carried with the crew, to allow longer range detection of the systems. Sonar based Identification system- The system is essentially a sonar based identification system, similar to those used in advanced fish finders, but specialized for use in the air. While the quality varies, the ultra-sonar high kilo hzt variant allows for an accurate 3-dimensional rendering of a 100 foot radius area, given enough time. It can easily pick up motion, and generally can pick up the presence of humans or other living creatures. While it travels faster through solid fixtures, thus allowing it to essentially, see through walls, it is difficult and times time to render such an environment, and therefore additionally requires a unit to stay outside the facility for a given time, to make out what might be a small area. These systems are also hard to see without large computer screens, and may take proper analysis to figure out how to enter the facility. Larger ones can be combined with the system to provide a larger area map out, and thus an easier stationary system to figure out the the layout of a facility or area. Radio communication Network- The armor comes equipped with a standard AN-PRC-148, a Multiband Inter/Intra Team Radio (MBITR), which is the most widely fielded handheld multiband, tactical software-defined radio, in use with NATO forces around the world. The radio is hooked up to the headphones and standard speaker of the armor, and can connect with the land warrior software present. These can be linked to the vehicle radio systems, which are substantially more powerful than hand held variants. Rather than carry large radios, these devices are generally carried by unmanned tracked vehicles, such as the RIPSAW. While the carried radios are much lighter and have a much smaller range, when connected to the larger radio unit, these unmanned vehicles can provide invaluable communication abilities, even at extremely far ranges, and they do not require a unit from the squad. Power Source- The lithium–titanate battery is a type of rechargeable battery, which has the advantage of being faster to charge than other lithium-ion batteries. Titanate batteries are used in Mitsubishi's i-MiEV electric vehicle and Honda uses them in its EV-neo electric bike and Fit EV, which will be launched in summer 2012. A lithium–titanate battery is a modified lithium-ion battery that uses lithium-titanate nanocrystals on the surface of its anode instead of carbon. This gives the anode a surface area of about 100 square meters per gram, compared with 3 square meters per gram for carbon, allowing electrons to enter and leave the anode quickly. This makes fast recharging possible and provides high currents when needed. The disadvantage is that lithium-titanate batteries have a lower inherent voltage, which leads to a lower energy density than conventional lithium-ion battery technologies. Toshiba released a lithium–titanate battery, dubbed Super Charge Ion Battery (SCiB).The battery is designed to offer 90% charge capacity in just 10 minutes. SCiB batteries are used in the Schwinn Tailwind electric bike. Toshiba has also demonstrated its use as a prototype laptop battery. Toshiba SCiB batteries are also used in Mitsubishi's i-MiEV and Minicab MiEV electric vehicles, and Honda uses them in its EV-neo electric bike and Fit EV model which will be launched in summer 2012. The batteries within the land warrior system are based off of these batteries. Heart Rate Monitor- The heart rate monitor goes onto the wrist, like a standard watch, and can even tell time. The heart rate monitors comprises two elements: a chest strap transmitter and a wrist receiver or mobile phone (which usually doubles as a watch or phone). In early plastic straps water or liquid was required to get good performance. The units now use conductive smart fabric with built-in microprocessors which analyze the EKG signal to determine heart rate. Strapless heart rate monitors allow the user to just touch two sensors on a wristwatch display for a few seconds to view their heart rate. These are popular for their comfort and ease of use though they don't give as much detail as monitors which use a chest strap; to get more detailed information longer time frames with the chest monitor are required. It can also be utilized to measure blood pressure; this information is particularly useful for medics or to determine the medical capabilities of a soldier. Bone Conduction Headphones- Bone conduction is the conduction of sound to the inner ear through the bones of the skull. Bone conduction is the reason why a person's voice sounds different to him/her when it is recorded and played back. Because the skull conducts lower frequencies better than air, people perceive their own voices to be lower and deeper than others do. This also explains why a recording of one's own voice sounds higher than one is accustomed to. Some hearing aids employ bone conduction, achieving an effect equivalent to hearing directly by means of the ears. A headset is ergonomically positioned on the temple and cheek and the electromechanical transducer, which converts electric signals into mechanical vibrations, sends sound to the internal ear through the cranial bones. Likewise, a microphone can be used to record spoken sounds via bone conduction. The first description, in 1923, of a bone conduction hearing aid was Hugo Gernsback's "Osophone", which he later elaborated on with his "Phonosone". Bone conduction products have following advantages over traditional headphones: Ears-free, thus providing extended use comfort and safety High sound clarity in very noisy environments, can be used with hearing protection Can have the perception of stereo sound Throat Microphone- Throat Microphone- A throat microphone, also laryngophone, is a type of microphone that picks up sound directly through sensors in contact with the neck. Because of this design, it is able to pick up speech in loud environments, such as on a motorcycle or in a night club, where other types of microphones would not function well because the speech would be drowned out by background noise. This type of microphone is also able to pick up whispers and works well in an environment where one has to keep quiet while communicating with others at a distance, such as during a covert military operation. Throat microphones were also extensively used in World War II-era aircraft, and by German tank crews. Newer single-element designs are available that make the throat microphone much more comfortable to wear than earlier units. Additionally, this next generation of throat microphones provides varying outputs and frequency responses to accommodate a wide variety of communication devices such as digital and analog portable radios, Tetra & P25 systems, & cellular phones. Throat microphones are very useful in loud environments or when respiratory protection is required. Many full-face SCBA, SAR, SABA PAPR or re-breather masks do not have a provision for a microphone inside the mask. The throat microphone can be used safely as it is positioned outside the mask's face seal and as such does not compromise the respiratory protection provided by the mask nor does it violate mask approvals and certification. Throat microphones are popular with paintball players as they allow competitors to insert communication equipment easily under protective masks and gear. Additionally the ability to whisper communications enables players to not give away their position during games. does not feature whisper communications and requires users to speak at full volume. A throat microphone is available for iPhone, which is similar design to the armscale computer used by the computer system.

Enhanced Biomechanics While the suit itself provides substantial strength enhancement via purely mechanical means, as it possesses a powered exoskeleton, it also works to improve the over-all physical capabilities of the user in general, by enhancing their natural biomechanics. Initial aspects of the design are as such that it removes a lot of the pressure off of the user, such as by redirecting the weight of the armor and the combat pack and distributing it more evenly around the body, as well as directing it straight into the ground, using mostly unpowered systems. Due to it's design, it is more ergonomic than most semi powered exkoseletons, but consumes more energy. It places a large portion of balance and coordination on to the suit, having a wide array of sensors and gyroscopes. It is also can effect the nervous system; by reading signals in the brain, it can nearly instantly transfer them to the body through electric impulse, and thus speed up the reaction time of the user. It can also smooth out actions, much like in an F16, so that a person will move in a more efficient way; in addition their body could be controlled to make certain motions, thus giving faster operating capabilities and more things that their muscle memory might not be capable of (as their suit can control the body through nerve stimulation). The suit does not actually possess an artificial heart, as it is constantly on the user, but the suit is designed to work in concert with this heart; while the heart of the host individual is not removed, it is slowed down by the pacemaker unless the backpack is turned off or disconnected from the heart. The artificial heart pumps blood about 3.5 times faster through the body than what the host person would ordinarily experience at resting levels; since it utilizes a very low pressure hydraulic heart, it can achieve such high rates without an increase in blood pressure; in fact, the person with the heart could be technically considered "dead" due to their low blood pressure, as their body has a virtually non-existent pulse. This in turn allows significantly more blood to circulate through the body without issue, even at greatly increased levels, and could in theory sustain the equivalent of an adrenaline rush indefinitely. Regardless, this in turn speeds up brain power, lifting capacity, and reaction time, without the ordinary detriments associated with long time adrenaline exposure. Additionally, the suit routinely adds PFC's, glucose, electrolytes, and other nutrients to the body; since the tubes hook up to major body parts, including the neck, wrists, thighs, ankles, and other areas, the materials are distributed through the body much quicker and to certain body parts faster than a typical intravenous pump. If the body is estimated to be working with extreme difficulty, it will pump more of these materials into the blood stream in order to give more energy, locally and totally, to increase performance. As well, it can absorb these materials from the bloodstream using a nano-graphene filter, and then remove them, in case they become too much; as well, it can remove other toxins and build up materials from the body, like excess lactic acid, to a limited extent. Most notably, the suit has limited medical benefits. Artificial blood, with 5 times the capacity of ordinary blood, and a significantly longer shelf life, can be pumped into the body if the vital signs begin to alter, suggesting the user needs emergency attention. The internal thermoregulation suit itself can seal up and tighten areas that have been wounded, and provide quick clot to quickly slow down bleeding. While this does not treat the injury itself, the quick reaction of the equipment can drastically increase survival rates, if the user is damaged. This system relies naturally on the vital signs indicator by the thermal regulator, and in addition transmits this information to the commanders and squad to keep them aware of the current state of their units. Artificial HeartThe average heart produces about 1.3 Watts of energy, every second, for over 75-100 years. The heart is relatively inefficient, below 10% efficiency, suggesting it takes at least `10-13 watts of continuous power to power the average heart. A primary function of the heart other than to pump blood is to promote which direction oxygenated and unoxygenated blood goes. While this is through a method of diffusion and osmosis balance this also promotes which direction nutrient filled blood goes too, as well; in addition, in regulates it's rate depending on hormones, to tell the body how to go faster or if it needs to work harder. A primary problem with artificial hearts is getting the power and capabilities necessary to knowing how to regulate speeds. The system in the backpack works in two ways, the first one which is to monitor the heart rate; while regulated to 20 BPM with a pace masker (to preserve the function of the heart, so it won't atrophy) which will immediately subside if the pack is damaged, oxygenated and unoxygenated blood and can artificially pressed through the heart to filter out blood, and as well the heart can be monitored to be made aware of how fast the pack should beat based on adrenaline and other functions. The heart pump uses a hydraulic pump and "turbine" [ 1][ 2][ 3], much larger than the heart, to circulate blood up to roughly 5 times it's given limit, although it usually operates at around 3.5. While this would ordinarily raise blood pressure enormously (to increase the heart rate to such levels), due to the constant circulation of the blood rather than irregular thumps the over-all blood pressure at any one point is much lower than even in an ordinary human. This does however cause the circulation to be different, and the 20BPM of the heart is still a minor part that gives partial blood pressure, rather than being nearly absent. Through this process the blood can circulate much faster throughout the body, without undue strain on the body. This entire process uses about 5 watts, due to be substantially more efficient in operation than the human heart. Because it does not need to monitor the hormones and other chemical nearly as much, due to it's high rate of circulation over compensating for problems that may increase the heart rate, such as adrenaline, it is less of a hassle to try to match the heart rate associated with the hormone levels. Still, there are methods for measuring these levels in the body. As a result of the increased heart users, most users can operate as if on an adrenaline rush for long periods of time. Their reaction time is faster, their brain is faster and absorbs more information, and they have increased strength. Primarily, however, the increased heart rate helps to improve endurance, taking the stress off of the human heart. By placing it on to the machine, the heart does not need to be at elevated levels during strenuous exercise, or when pumping the incredibly vicious blood. This not only helps to avoid wearing out the heart, but allows for greatly increased endurance, allowing for constant physical exertion at peak levels nearly indefinitely. Obvious other restrictions still apply, however it can improve performance drastically. The heart, while it does not consume a substantial amount of energy, requires constant upkeep, and due to the increased blood supply, would but difficulty on the host if it stopped working; thus, the heart relies upon an RTG which provides a small but steady supply of power for many decades. Detecting Hormones and other chemicals in the bloodThe heart is monitored using various heart monitors, in order to conclude how much of each hormone is present in the blood using the heart as a monitor to determine how fast to pump based on hormones like adrenaline. However, Infrared spectroscopy, much like what is used in alcohol breathalyzers, is used to measure how much of each chemical in the blood. Tuned to measure what's in the blood, the infrared spectrometer can detect the presence and how much of each chemical is in the blood, in order to tell the heart how fast to beat. Despite this, the artificial heart operates well over it's necessary limits, suggesting that even if adrenaline desired to have the heart pumping 3 times it's limit, since it is usually far over this level, it more or less would be irrelevant. However monitoring the heart's responses and the level of hormones in blood in order to understand how to beat faster can be important and is an available function of the suit should other functions fail, or in order to try to get the suit to attune to the bodies need, albeit perhaps more quickly. Blood dopingErythropoietin use, or EPO, can be utilized to increase blood cell content, and thus oxygen, nutrient, protein, and other carrying capacities. By increasing the total volume of the blood, more oxygen can go to the brain and to repair tissue after it's damaged, as well as nutrients, faster, more oxygen can be absorbed by the lungs and dissolved into the blood, can increase performance. In addition to healing faster, increased endurance is possible through blood doping, which not only doubles the amount of oxygen a person can consume from their lungs, but also transports more nutrients to muscles and other organs faster. While there can be some drawback to increasing the amount of blood in the body, such as increased iron absorption and potentially overworking the heart, as long as the body stays below relatively safe hemocrit levels, there is little chance for issue. As human blood is not as thick as it could be, increased thickness to a degree can be relatively harmless. The effects are along the line of high altitude training, without any of the potential drawbacks of low oxygen training. Maximum safety limits can be hard to determine, as some people live in conditions which necessitate much higher concentrations, but in general double the ordinary hemocrit levels are generally considered safe. The system is designed to utilize triple the ordinary blood volume of a normal person, as afforded by the artificial heart, which takes most of the strain off of the heart and cardiovascular system, particularly as it decreases blood pressure to harmless levels. Oxygen ConcentratorThe Oxygen Concentrator more or less concentrates ambient oxygen, providing more from the air, and increasing the total amount of oxygen exposed to the user. Oxygen concentrators operate on the principle of rapid pressure swing adsorption of atmospheric nitrogen onto zeolite minerals and then venting the nitrogen. This type of adsorption system is therefore functionally a nitrogen scrubber leaving the other atmospheric gasses to pass through. This leaves oxygen as the primary gas remaining. PSA technology is a reliable and economical technique for small to mid-scale oxygen generation, with cryogenic separation more suitable at higher volumes and external delivery generally more suitable for small volumes. At high pressure, the porous zeolite adsorbs large quantities of nitrogen, due to its large surface area. After the oxygen and other free components are collected the pressure drops which allows nitrogen to desorb.An oxygen concentrator has an air compressor, two cylinders filled with zeolite pellets, a pressure equalizing reservoir, and some valves and tubes. In the first half-cycle the first cylinder receives air from the compressor, which lasts about 3 seconds. During that time the pressure in the first cylinder rises from atmospheric to a few times normal atmospheric pressure (typically 20 psi/138 kPa gauge, or 2.36 atmospheres absolute) and the zeolite becomes saturated with nitrogen. as the first cylinder reaches near pure oxygen (there are small amounts of argon, CO2, water vapor, radon and other minor atmospheric components) in the first half-cycle a valve opens and the oxygen enriched gas flows to the pressure equalizing reservoir, which connects to the patient's oxygen hose. At the end of the first half of the cycle there is another valve position change so that the air from the compressor is directed to the 2nd cylinder. Pressure in the first cylinder drops as the enriched oxygen moves into the reservoir, allowing the nitrogen to be desorbed back into gas. Part way through the second half of the cycle there is another valve position change to vent the gas in the first cylinder to vent outside. That keeps the concentration of oxygen in the pressure equalizing reservoir from falling below about 90%. The pressure in the hose delivering oxygen from the equalizing reservoir is kept steady by a pressure reducing valve. The total concentration increases from ordinary atmospheric concentrations of 20.9% to about double at 40%. Since this is considered relatively safe, in conjunction with various anti-oxidants, it is an easily usable increase in oxygen concentrations to help improve performance in the field. While it does not increase strength, increasing the total amount of oxygen dissolved in the blood helps to increase endurance and growth, as well as healing in nearly all tissues of the body. Semi-powered ExoskeletonPart of the purpose of the semi powered exo skeleton is the weight distribution and load carrying over the entire body. As the weight is distributed more evenly and redirected through the suit into the ground in a more appreciable fashion, it is easier to carry the load and thus reduces the strain on the user. However, the exoskeleton also provides limited assistance to the user, allowing some redirection of the forces throughout the suit as a result of a semi powered exoskeleton suit. While the exoskeleton designed by MIT utilizes 1 watt, the exoskeleton utilized in this suit utilizes closer to 10 watts. While the same fundamental principles apply, the design works at different elevations and does not substantially change the users gait to gain the advantages, at the expense of efficiency. Still, it helps to significantly reduce the stress and load off the user; since the weight is put into the suits lower extremities, instead of just a single tube, it helps to distribute the weight easier and balance it more appropriately. While this does not enhance the users strength, it does redirect the weight in such a way as to make it easier to carry, and thus helps to, partially, increase the users strength. ThermoregulatorThe suit is designed to reduce energy consumption and stress on the user by helping the body maintain an ideal temperature, regardless of the environment. Like a personal air conditioner or heater, it keeps the user warm or cold, to near ideal body temperatures in any range of environments, reducing the amount of energy required to maintain homeostasis; in addition, it reduces water consumption and salt loss from sweating and general dehydration, in general improving physical performance. It helps particularly during intense exercise, when the body starts to overheat. The ideal human body temperature is close to 98.6; The ideal room temperature however, is approximately 60-70 degrees, which is much harder to reach. In addition, proper body temperature conditions differ throughout each body part, so the suit is designed to adapt it's temperature depending on the place of the body, such as the face, hands and nose, which tend to be slightly colder. The primary advantage of the system is it's low energy consumption. As a result of extremely effective insulators, the suit can easily keep the body at desired temperatures utilizing coolant systems over the whole body, which drastically increase performance in the field. Concept designs have shown considerable promise via cooling gloves [ 1][ 2][ 3][ 4], although the suit itself utilizes an entire fully body unit, which surrounds the entire body. Most key areas in the body are covered, such as the hands or feet, and in addition sensors are used to appropriately gauge how the body should be cooled. If the body begins to overheat, the suit will begin to cool key areas of high vascular content down, in addition to areas over the entire body.

Larger scale systems The Land warrior program is not just a suit of armor, but a system, which provides a multitude of advantages to soldiers. From invaluable intelligence at the fingertips of the soldiers via the network of communication relays, to the more tangible increase in range and firepower from the armored vehicles, the true secret of the system itself is it's ability to work with other units to form a more cohesive battlefield environment. Soldiers can be transported by vehicles connected to the land warrior system; these same hybrid vehicles can provide not only large radio communication fixtures, access to mortars, missiles, or higher strength weaponry, drones, and other beneficial features not usually available to infantry, but additionally be used to provide power for the system, serving as a virtual generator, in addition to transporting them to the sight, rather than requiring soldiers to move out on foot. These large vehicles can serve as launching platforms for UAV's, UGV's, or other parts of the system, to allow larger equiment, usually not capable of being carried around by troops, to be integrated into the over-all combat team. More powerful and faster processing computers found inside the vehicles can relay information to the troops and vice versa, cutting down on the size of the computers required for such a job on the person or increasing their capabilities in the field. This allows larger, more detailed, and more dynamic up to information on the battlefield (from maps to pictures of targets), with troops and commanders alike possessing access to warzone wide information, including quick communication and video and information relay, in addition to a map out of the general area with satellites, aircraft, and drones. With the HULC exo-skeleton, the extra weight of land warrior system can be easier to carry, in addition to other equipment. The HULC is a battery and fuel cell powered, lower extremity exoskeleton. It carries up to 200 lbs (excluding the weight of the armor itself, or an additional 53 pounds), distributed between the front and back of the device. Loads attach to the exoskeleton system and are carried by the exoskeleton, bypassing the human operator, which put them into the ground, and take them off of the back and joints of the user. The effective forces felt by the operator are dramatically diminished reducing the risk of muscularskeletal injuries. Due to the fact the suit is integrated into the armor, which provides some of the support for the user, the hulc system only weighs 33 pounds. The HULC provides power assistance at the hip and knee joint. The innovative hydraulic architecture is highly efficient enabling the system to run on batteries. Other exoskeleton systems, such as the Raytheon/SARCOS XOS 2 system are tethered to a power generator. The current battery capabilities, using quickly rechargeable lithium titanate systems, with longer cycle live's than lithium ion, allow for over 24 hours of continued transit in the field, with 200 pounds; more or less, this is approximately a 60 kilometer range at 4 kilometers per hour. The system can utilize a hydrogen fuel cell for 96 hours of constant operation, and can carry additional fuel (30 pounds) for 6-8 days of operation, depending on the operational load out and speed. This is an approximately 240 kilometer range, or 150 miles, or an additional 225 or 300 with the additional fuel. For the first 24 hours or so, the rechargeable battery is utilized; this then transitions to the perishable fuel source of hydrogen, although this fuel is more difficult to replace. The range of the system is approximately 60 km per day, although it's likely the user will not travel this distance in this time. If weather permits, solar power can power the system indefinitely. The solar panels are covered in ALON, a high strength material which can protect the solar panels from damage sustained during combat, but also allow enough light in for the photovoltaic cells to operate efficiently, unlike traditional glass or other protective materials. The solar panels are primarily present on the shoulders and helmet. 12 hours of solar power are theoretically capable of allowing the device 24 hours of transit; thus, if the vehicle is in transit for 12 hours out of the day, it is possible to completely replenish the power needed for travel during this time. Additionally, the hybrid vehicle can serve as a power source for the system, by allowing the users of the lighter weight infantry exoskeletons to sap off a small amount of energy from the battery of the vehicle (found in hybrids) to power their suits, in addition to refuelling from the hydrogen packs (which are much easier to carry in the vehicle than on the person, due to their weight). The hybrid vehicles themselves not only has a longer range than traditional ones, but additionally reduces the number of fuel trucks needed in the environment and increases their necessary range from the battlefield; this same system can also be used to power drones, the land warrior system, and the exoskeleton. The exoskeleton is generally expected to be used in conjunction with armored vehicles, usually APC's, which can transport the soldiers to the battlefield and then allow the exoskeleton and soldier's inherent strength to get them the rest of the way needed on foot. While infantry are smaller and more stealthy, being manoeuvrable and agile, providing numerous advantages which large vehicles tend to lack, in general, infantry are utilized to prevent collateral damage or the death of innocent people, by using focused, precise attacks. The human brain can distinguish between targets and discriminate amongst the populace, determining whether or not a target is a civilian or enemy, and whether or not they should or should not be killed. Even the most advanced technology still lacks this ability, and relies heavily on human operators and expensive, if not simply risky equipment. Situations where vehicles are accessible, but not preferable, such as a hostage rescue environment, or just an environment where the enemy hides among civilians, virtually as human shields, can necessitate the use of smaller, more precise soldiers, who are unfortunately at risk from enemy attack; personal body armor that can be realistically carried by the person and stop common threats is generally not available, such as ak-47 or PKM rounds, due to the fact that the weight or bulk of the equipment is generally too high, especially considering the need for the additional weight of a combat load. By using the array of exoskeletons and biomechanical enhancements, the soldier can realistically carry such armor into combat, even if limited by the power source for such the relatively short time. Thus, transporting the soldier via mechanical means, as far as possible to the battlefield, by the vehicles, and providing a nearly infinite power supply in comparison (I.E. the engine to produce electricity, the ability to carry dozens of hydrogen fuel cell packs), takes the strain off of the soldiers, and broadens their capabilities beyond that of what the exoskeleton could do alone. Thus, in essence, the APC's or vehicles the AMAP system is designed to work with, not only can transport them to the sight, but recharge their batteries and power supply as well, serving both as a mobile generator and a rolling barricade. This is a particularly useful feature in house to house clearing, which are brief but incredibly dangerous, and currently rely entirely on skill, strategy and sheer will or physical capabilities to have soldiers avoid being killed, rather than anything systematic which nearly guarantees survival assuming all things are done correctly. By being able to wear the armor that would otherwise be too heavy, at least for a short time period, into these particularly dangerous environments, it can dramatically increase the success rate as well as the survival rate of soldiers in these otherwise precarious environments.

CBRN (Chemical, Biological, Radiological, Nuclear) Suit CBRN (pronounced C-BORN or C-BURN) is an initialism for chemical, biological, radiological, and nuclear. It is commonly used worldwide to refer to incidents or weapons in which any of these four hazards have presented themselves. The term CBRN is a replacement for the cold war term NBC (nuclear, biological, and chemical), which had replaced the term ABC (atomic, biological, and chemical) that was used in the fifties. The addition of the R (for radiological) is a consequence of the "new" threat of a radiological weapon (also known as the "poor man's atomic bomb"). Since the start of the new millennium, a new term – CBRNe – was introduced as a replacement term for CBRN. The e in this term represents the enhanced (improvised) explosives threat. CBRN defense (CBRND) is used in reference to CBRN passive protection, contamination avoidance, and CBRN mitigation. A CBRN incident differs from a hazardous material incident in both effect scope (i.e., CBRNE can be a mass casualty situation) and in intent. CBRN incidents are responded to under the assumption that they are deliberate, malicious acts with the intention to kill, sicken, and/or disrupt society. Evidence preservation and perpetrator apprehension are of greater concern with CBRN incidents than with HAZMAT incidents. SuitThe suit used is considered to be at a level "A" protection. This is the highest level of protection against vapors, gases, mists, and particle, which consists of a fully encapsulating chemical entry suit with a full-facepiece self-contained breathing apparatus (SCBA) or a supplied air respirator (SAR) with an escape cylinder. A crew member must also wear boots with steel toes and shanks on the outside of the suit and specially selected chemical-resistant gloves for this level of protection. The breathing apparatus is worn inside (encapsulated within) the suit. To qualify as Level A protection, an intrinsically safe two-way radio is also worn inside the suit, often incorporating voice-operated microphones and an earpiece speaker for monitoring the operations channel. The suitThe suit is based off of the British MK IV NBC Protective Suit and is worn in conjunction with a respirator, gloves and overboots, and offers protection against all known chemical warfare (CW) agents. Interestingly, the suit is designed to be worn under the armor, rather than over it, although in theory the suit could be used for either situation.The life of the suit in operations depends on the level of attack. In most situations it can be worn for up to a month and still offer protection to the wearer. Under extreme conditions of multiple attack it may be necessary to change the suit after 24 hours. In addition to providing protection against toxic agents in both liquid and vapour form, the suit is also self-decontaminating by encouraging rapid evaporation. Furthermore, by virtue of its flame retardancy, it offers a high level of protection not only against conventional fire, but also against the thermal pulse resulting from a nuclear burst. DescriptionThe MK IV is a two-piece suit consisting of a smock and trousers. The smock, which is single breasted, has a front opening which can be closed with a slide fastener and also touch and close tapes. It has an attached hood with an elasticated face opening, which gives a good seal around the respirator. Touch and close strips are also provided at the cuffs and hips to allow easy individual adjustment for size. Bellows type pockets, with stitching penetrating only the outer layer of the main suit are provided on each breast and on the right sleeve, and a patch pocket with divisions for pens is fitted on the left upper sleeve. The trousers are of pyjama type with a gussetted front end with brace tapes sewn at the back, and loops at the front to give over-the-shoulder braces which can be tied at the front. Waist and the lower legs can be adjusted by touch-and-close fasteners. Bellows type pockets are provided on each thigh, together with detector patches. Both smock and trousers are designed with the outer and inner layers of fabric constructed separately and only joined at the edges, thus reducing any possibility of ingress through stitch holes. MaterialsThe complete suit is constructed from two layers.The outer material is made of monacrylic fibres reinforced with polyamide fibres. It has a strong, hard-wearing outside surface. A silicone treatment is applied to make the garments shower-proof, and to permit rapid spreading of liquid chemicals, which in turn speeds up evaporation. This reduces the loading on the second layer, whose main function is to act as chemical barrier. The inner fabric is based on activated charcoal as a means of protection against toxic gases and vapours. It.s bonded to a non-woven fabric, which is flame retardant. A fluorocarbon finish is applied as an oil repellent, thus acting as a further barrier to toxic liquids. This combination of repellents represents a chemical barrier which is highly efficient, yet air permeable and thus imposes low heat stress. This liquid control system formed by a wicking layer over an oil-repellent layer permits the incorporation of less charcoal than in other systems, which in turn results in a fighter garment and smaller package size.

Radiostopic Thermoelectric Generator The Radiostopic Thermoelectric Generator (RTG) is an electrical generator that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect. RTGs have been used as power sources in satellites, space probes, and unmanned remote facilities such as a series of lighthouses built by the former Soviet Union inside the Arctic Circle. RTGs are usually the most desirable power source for robotic or unmaintained situations that need a few hundred watts (or less) of power for durations too long for fuel cells, batteries, or generators to provide economically and in places where solar cells are not practical. Safe use of RTGs requires containment of the radioisotopes long after the productive life of the unit. RTG's are used extensively for use in the artificial heart, to provide the constant power needed to prevent it from stopping; due to the increased blood volume, without the artificial heart constantly working, it can put extensive strain on the heart, although likely not enough to immediately killer the host. A primary key issue with most RTG's is fuel efficiency. While they can operate for several decades, converting the heat produced via the radiation into electricity, they typically have incredibly low efficiency, unless utilizing otherwise expensive materials. Americurium 241 is utilized over Plutonium 238 due to the increased volume and ease of extraction due to it's purity in the nuclear process. It possess approximately 4.92 times the lifepsan of plutonium, but produces approximately a quarter of the power. While it produces stronger radiation than P238, it is still the second easiest to contain of all fuels. Most RTG's get between 3-8% efficiency of heat to energy production. Utilizing some newer, experimental designs, the RTG's can achieve nearly 20% efficiency, although they depend on a radically different method of converting the heat to electricity; in the particular case of the RTG, they convert infrared radiation to electricity. While only a portion of the total heat energy, the conversion efficiency is much higher, and thus more energy can be produced from this process. The system therefore requires approximately 17.5 grams of Americurium-238, to produce around 3.5 watts of energy. The RTG is utilized for it's small size and relatively compact design. While Radiostopic Thermoelectric generators generally tend to be more efficient, the RTG is intended for use with the artificial heart, and thus needs to be easy to round on the person at all times. While Americurium tends to be rather rare and expensive, and it easy to siphon off from the nuclear process.
