    摘要: A tag operates in an environment where transmitted interrogators are not possible or desired. High-efficiency diode rectifiers and low-power oscillators are used in combination with an energy storage element and hysteretic switch. The combination of multi-diode rectifier, low power tunnel diode oscillator, energy storage element and hysteretic switch allow for nanowatt levels of received RF power to be stored to produce micro-watts of RF transmit power. The device trickle charges off of ambient RF radiation until enough energy is stored for transmission.

    摘要: A wireless network connection system remotely connects to a network without the use of crystal reference oscillators. This provides communication at long range using a low transmit Effective Isotropic Radiated Power (EIRP). Operation is obtained through a combination of injection locking the system clock to the fundamental frequency of a remote reference oscillator, injection locking the transmitter to the third harmonic of the remote reference oscillator, a micro-watt RF receiver, and a network connection.

    摘要: Nuclear quadrupole resonance substance detection at a distance is provided by crossed or overlapping high frequency beams in which the frequency of one of the beams is offset with respect to the frequency of the other beam by an amount equal to the resonant frequency of the non-linear material to be detected. The presence of energy at the offset frequency within the overlapping beams pumps any non-linear material within the overlapping beams to cause stimulated emission which is detected, in one embodiment, utilizing a network analyzer, along with correlation of the detected stimulated emission signature with a library of signatures for predetermined substances.
