A communication system provided in a working vehicle includes: an identification device that stores identification information; a communication device that outputs electric waves to communicate with the identification device; an ambient temperature judging unit that judges whether or not an ambient temperature of the environment in which the identification device is disposed exceeds an operational temperature at which an operation of the identification device is ensured; and a communication controller that prohibits the communication device from outputting the electric waves when the ambient temperature judges that the ambient temperature exceeds the operational temperature.

An identification or messaging system is provided that has embodiments including a embodiment with a structure with different faces and a base with reflective or resonance panels which are positioned at different receiving angles to detect direct signals and amplify them including in a sequence to be detected by an active emitter that emits electromagnetic radiation that is reflected and steered or resonated off or with the panels. An emitter can be an aerial platform with the emitter and a library of reflected or resonated signals that are associated with a particular sequence of panels on the structure which are associated with a particular entity identification or message. Thermal patterned and/or magnetic patterned panels (e.g., for backplane beamforming) and return signal steering can also be provided. Embodiments with secondary signaling systems can also be provided. A variety of various embodiments and methods are also provided.

Methods and systems for plasmonically enhanced bionanoantennas for tagging, tracking, and locating targets of interest at long distances in both day and nighttime conditions. The nanoantennas are used to tag a target of interest and emit a wavelength to impart a unique biometric signature. The nanoantennas are detectable by selectively harvesting and plasmonically enhancing incident light in the visible region, then upconverting that energy through an activated phosphor.

A system simultaneously tracks multiple objects. All or a subset of the objects includes a wireless receiver and a transmitter for providing an output. The system includes one or more wireless transmitters that send commands to the wireless receivers of the multiple objects instructing different subsets of the multiple objects to output (via their respective transmitter) at different times. The system also includes object sensors that receive output from the transmitters of the multiple objects and a computer system in communication with the object sensors. The computer system calculates locations of the multiple objects based on the sensed output from the multiple objects.
