Claim:
1. A passive-tracking system for passively tracking a living being, comprising: a visible-light sensor that is configured to generate a series of visible-light frames based at least in part on visible light that is reflected off an object; a sound transducer that is configured to generate a series of sound frames based at least in part on sound reflected off the object; a thermal sensor that is configured to generate a series of temperature frames based at least in part on thermal radiation emitted from the object; a time-of-flight sensor that is configured to generate a series of modulated-light frames based at least in part on modulated light reflected off the object; and a processor that is communicatively coupled to the visible-light sensor, the sound transducer, the thermal sensor, and the time-of-flight sensor, wherein the processor is configured to:
