Patent Number Title Of Patent Date Issued
5485154 Communication device and method(s) January 16, 1996
The present invention relates to the areas of communication and/or identification of remote devices (active or passive). The invention has application where there is a need to identify or communicate with more than one remote device. The remote device may be embodied as a transmitter
5302954 Identification apparatus and methods April 12, 1994
An identification system comprising a transponder having receiver means adapted to extract powering energy from a surrounding electromagnet field, transponder transmitter means adapted to transmit at least one unique signal from the transponder, frequency generating means for generating
5196743 Low-power clocking circuits March 23, 1993
In switching a CMOS circuit comprising first and second switchable logic elements the first logic element is enabled so as to allow it to reach a steady logic state and the second logic element is not enabled until the first logic element reaches a substantially steady logic state. The
5173849 Integratable synchronous rectifier December 22, 1992
A synchronous rectifier comprising: switch means responsive to a control signal for selectively providing conduction of an applied AC signal, and driver means responsive to the applied AC signal and adapted to provide said control signal in synchronism with the applied AC signal, wherein
5107227 Integratable phase-locked loop April 21, 1992
An integratable phase locked loop (IPLL) comprising sampled data filter means adapted to receive a first reference signal, the filter means sampling the first reference signal (Ref In) to provide a second reference signal (Control Volts Out), and voltage or current controlled oscillator
5045770 Shunt regulator for use with resonant input source September 3, 1991
A regulator is provided for receiving electrical power from an external alternating magnetic field and developing a regulated output voltage. The regulator is operatively coupled to a resonant inductive circuit for obtaining input power. It includes a circuit for regulating output power
