Inventor: SHIMAKATA YUKIHIRO
IPC: H04L27/233
Filed: 1991-07-04
Abstract: In a differential-detection demodulator circuit, a PSK modulated signal is compared with a locally oscillated signal to obtain a phase difference between the two signals, whereupon the phase difference is demodulated. A phase detector circuit of the digital type outputs the phase difference signal.  The digital phase comparator circuit compares plural reference signals, which give predetermined delays to the locally oscillated signals having carrier frequencies, with the inputted modulated signals.  Preferably, a pulse signal having a phase difference between the inputted modulated signal and the locally oscillated signal is produced, and the pulse width of this pulse signal is measured by a counter.  By digitalizing the entire phase comparator, it is possible to realize demodulation with low electrical power consumption and simple circuit construction.

Title: Fail safe obstruction detector for door openers
Inventor: WAGGAMON DENNIS W
IPC: E05F15/00
Filed: 1991-12-13
Abstract: The light beam in an obstruction detector is coded into packets of pulses by a transmitter. When the light beam is received, the receiver recovers the code signal and supplies it to a code detection circuit. To detect the code, the circuit supplies the code signal and a delayed version of the code signal to an "exclusive or" gate. If the code is present, the gate produces a pulsed output resulting in a "safe" signal being sent to a door opener control circuit. If no code is present, the gate produces a relatively constant output resulting in an "unsafe" signal being sent to the door opener circuit. The "unsafe" signal is produced not only in response to obstructions, but also, in response to errors and malfunctions in the wiring to the transmitter and receiver and in the transmitter and receiver themselves. <IMAGE>
