摘要： A multilayer printed circuit board (“PCB”) coil that simulates a coil formed from litz wire. The PCB includes a plurality of alternating conductor and insulating layers interconnected to cooperatively form the coil. Each conductor layer includes a trace that follows the desired coil shape and is divided into a plurality of discrete conductor segments. The segments are electrically connected across layers to provide a plurality of current flow paths (or filaments) that undulate between the layers in a regular, repeating pattern. The coil may be configured so that each filament spends a substantially equal amount of time in proximity to the paired coil and therefore contributes substantially equally to the self or mutual inductance of the coil. Each conductor layer may include a plurality of associated traces and intralayer connector that interconnected so that each filament undulates not only upwardly/downwardly, but also inwardly/outwardly in a regular, repeating pattern.

摘要： A multiphase inductive power supply wirelessly transmits power in multiple phases. A primary circuit energizes multiple tank circuits in an out of phase relationship. A secondary circuit receives the power and recombines the power. The amount of energy in each phase is reduced compared to transferring the same amount of power using a single phase inductive power supply.

摘要： A wireless mesh network where a portion of the nodes have reduced receive sensitivity. The negative effects of the density of the wireless mesh network, such as interference, are reduced when fewer nodes receive messages to rebroadcast. In an alternative embodiment, some of the nodes of the mesh network are configured to not rebroadcast even if they receive a message. A method for configuring a dense mesh network is also provided. As many nodes as possible are discovered and registered in the network. Node characteristics of those nodes are adjusted to reduce or eliminate the negative effects of the dense mesh network so that additional nodes may be discovered and registered.

摘要： A monitor tag having a radio frequency transmitter and a patch antenna. The antenna is in communication with the transmitter and has a first conductive patch and a second conductive patch substantially parallel to each other, and separated from each other by a dielectric material in contact with both patches and having a thickness sufficient to create a gap between the patches wherein the radiation resistance will be controlled during operation of the antenna. The first conductive patch has a dimension of one-quarter or one-half wavelength, depending upon available space and desired pattern. Because the electric field is launched from the gap between the patches and is highly concentrated, bringing the monitor tag close to a metal object or attaching it thereto will have minimal impact on the impedance of the antenna. The monitor tag can be used for a number of purposes including asset protection and identification by affixing respective tags with conventional transmitters to respective metal and nonmetal articles and transmitting chosen respective information about each article. Of particular applicability is a monitor tag device worn by a person such that the wearer can be monitored with respect to chosen parameters as developed for observing or regulating and transmitted or received by the antenna of the present monitor tag invention.

摘要： Hard-wired analog adaptive cancellation for microwave receivers to cancel the interference generated by co-located transmitter employs a circuit having two or more quadrature taps on a delay line. The least and greatest delays provided by the delay line taps are selected so that the copies of the transmitted signals provided by the respective taps bracket the timing of the portion of the transmitted signal that leaks into the collocated receiver's input. Samples of received signals corrupted by interference from the transmitter are mixed with delayed samples of a transmission reference signal to develop a cancellation signal.
