The second test, after an hour of the first, was the stealth chamber. It contained a number of various items with differing stealth tech to hide them. It would be most interesting to see how it responded. The first was perhaps the most common, technology that hid the heat of an organic body or a droid's motors. The vast majority of these technologies created something of a vacuum of heat, where the temperatures did not properly match with the surroundings. The idea behind the sensor was that it would be able to detect even the minutest differences in temperatures. If a small region stood out and was unnaturally out of place then the droid would be able to detect it and hopefully respond to it as needed.
The second method was sound muting, if one could not hear the enemy then there was no way for the droids to easily locate the enemy. Therefore he needed a system that would allow his droids to pick up even the slightest sound, or the lack of sound. When one is capable of making a system incredibly precise it is possible for it to be used as an locator of its own. Sound reflected off of every physical object, whether physical or not. If a droid took a step, if its sensors were good enough it could hear the sound over and over again as it returned after bouncing off of the various objects around it. With a basic calculation it would be possible to use the information to create a near perfect image of what surrounded the droid without a single photo-receptor. Therefore, even if the enemy was capable of hiding all of their noise and was completely invisible in most other ways, the noise from the droid would bounce off of the enemy and the droid would be alerted to a threat nearby.
The third method was the method of air movement. Definitely related to the sound, as the two are intertwined in how they function, it works in a different manner. Rather than measure noise and calculate images based on reverberations, the air movement uses incredibly sensitive sensors to calculate the movement of air in the surrounding area. In this way, it would be possible to locate an organic by a number of methods, if it breathes then it would be visible by the intake and exhale of breath. If it has moving parts, then the movements cause air flow disruptions which are then capable of being seen by the sensors. The sensors are even capable, when set on the highest power usage, of catching the minute air movements caused by organic pores. The final method of locating a stealthed enemy is by the movement of air around the organic. No matter what form of stealth is used, air moves around a being, therefore this sensor is capable of finding an organic based on the air moving around them.
The fourth and most algorithmic of the lot is the ability to calculate light waves. In much the same way of the air movement detector, the light is calculated in an area around the sensor unit. This was chosen due to the fact that the vast majority of both stealth technology and Force techniques relied upon the bending of light around a person. This sensor could then calculate the change in light movement to find an unnatural disturbance in light movements. Thereby locating an enemy.
