摘要： A VLF beacon operates in the near field of the antenna, providing a low impedance (magnetic) wave located by employing simple amplitude gradient and phase alignment direction finding (DF) methods. When rotated, the beacon antenna radiates its signal with little attenuation. Beacon antennas include a loop antenna which has a 1/r3 B-field amplitude relationship with distance. The antenna radiation range is limited, but the detectable near field signal is strong. The receiver comprises a simple 2-channel RF front end with filtering and an A/D converter. The antenna for each channel is a much smaller ferrite rod loaded loop.

摘要： A system and method for decontamination of chemical and biological agents over terrain in an outdoor environment is provided that utilizes ultraviolet radiation to break up hydrogen peroxide into radical species that interact with chemical and biological agents to render them harmless. In a preferred embodiment, peroxide is dispersed in a contaminated area and the peroxide is then exposed to ultraviolet radiation that causes the peroxide to dissociate into radical species. The interaction of the radical species formed by the peroxide dissociation with the chemical and biological agents renders them useless.

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 wideband meander line loaded antenna is provided with a capacitive feed to lower the reactance of the meander line antenna such that at lower frequencies the antenna reactance goes negative to cancel out the reactance of the meander line and distributed capacitance. The resultant lowering of the low frequency cut-off for the antenna permits the antenna to be used, for instance, in cellular phone applications in which not only are the cellular frequencies accommodated by the antenna, but also PCS and GPS frequencies as well. With the capacitive, feed the low frequency cut-off is lowered by as much as 30% over standard meander line loaded antennas.

摘要： Techniques are disclosed for optical switching and data control, without the interaction of electronic switching speeds. In one example embodiment, a common cavity optical latch is provided that that can hold an optical state for an extended period of time, and the operation of which is controlled optically. Optical phase control allows optical modal switching to be employed between two common optical cavities, using incident optical signals and the way in which the cavities manipulate the phase within them to lock in one or the other configuration, thereby forming an optical latch. The optical latch is implemented in an integrated fashion, such as in a CMOS environment.
