So the computer is piecing together evidence from a wide array of sensors. The computer is frequently shown being able to theorize and extrapolate from available data based on spoken natural language commands.

In this case, they explicitly infer the presence of life based on "localized decreases in entropy." (Things were not as random within specific areas within the micro-verse in specific ways which indicated life-forms were responsible.) And in Star Trek: Deep Space Nine they find a tiny little miniature universe and their sensors can detect there is life in it.When they scan a ship for "life", they appear to actually scan for "life" - it is pointed out at least once in Star Trek: The Next Generation that their sensors can pick up artificial life, such as androids.detector for whatever Green Rocks or Phlebotinum residue they're looking for this week. Standard tricorders can detect people and give some indication on their physical status, but for medical diagnosis specialized medical tricorders are brought out. The tricorder combines this trope with The Little Detecto it's a hand-held, all-purpose note with one partial exception.Interestingly, one episode of Star Trek: Voyager featured them finding the wreck of an early 21st century Mars mission ship which appeared to be the first to mount an Everything Sensor - that's virtually how it was described!.Spock: Our ship's instruments are specifically designed to locate and identify any object in our universe, be it energy or matter. Much tension is derived from trying to figure out what a distant enemy warship formation are doing now when all the heroes know is what they were doing minutes or hours ago, or infer what's going on inside a space habitat or an outpost beneath the surface of an airless planetoid from whatever radio traffic they can intercept. The sensor systems aboard a warship are explicitly limited to optical and infrared cameras and wide-spectrum radio telescopes, and both the sensors themselves and the ship-to-ship voice and data links are limited to the speed of light.

Davenant had simply connected the thermopile with the galvanometer, blinkered the lens to provide sharp directionality, and come up with an infrared spotter. He needed a single device, rugged and portable, which could be adjusted to perform twenty different functions.

the largest collections of neurons he sees). Instinctively, he combines this ability with his training, which allows him to shoot shapeshifters in the brain (i.e. In one novel, a Space Marine gets empathic powers, allowing him to "see" nervous systems of living creatures.

Space Marines are trained to be able to identify signatures at a glance. The author usually mentions that the sensors simply return the "energy signature" of the target, and it's up to either the operator or the machine to figure out what it could be based on known signatures. In The History of the Galaxy books, pretty much all sensors act this way.
