Abstract: An arbitration circuit included in a semiconductor IC sequentially gives priority to competitive request signals applied to N input terminals (where N is a natural number equal to or greater than 3). The circuit comprises N input terminals ( a - c ), N output terminals ( d - f ), and gate circuits (1-6) arrayed to form a matrix with N rows and N-1 columns such that N-1 gate circuits are connected in series between the N input and output terminals, respectively. Gate holding circuits (16-18) are driven in response to passage of a signal through any one gate circuit and hold, until completion of inputting of said signal, the other signals to the gate circuits in the same row and the previous column(s). Gate closing circuits (13-15) are driven in response to passage of a signal through any one gate circuit and close, until completion of inputting of said signal, the gate circuits in the other rows and the same column except the gate circuit where the signal is held by the gate holding circuit. Gate opening circuits (10-12) are driven in response to passage of a signal through any one gate circuit and open the closed gate circuits in the other rows and the preceding column. A pulse generator included in the IC generates a desired pulse in response to an output signal obtained from a predetermined terminal. The pulse generator comprises a capacitor (102) disposed between a predetermined terminal and a predetermined potential (104), a diode-­connected first MOS transistor (103) disposed between the predetermined terminal and a power supply terminal (105), and serving to drop the supply voltage of a power source by a value corresponding to the threshold voltage thereof, a load (101) disposed between the predetermined terminal and the power supply terminal (105), and a diode-connected second MOS transistor (106) disposed between the predetermined terminal and the power source and operative to discharge the capacitor (102) in response to the occurrence of a momentary change in the, supply voltage.

Abstract: An intrusion detector and method of operating the detector is disclosed. The detector comprises a means including an antenna for transmitting spaced pulses of radiation energy of a given frequency throughout a region to be protected. Means are also provided for receiving the radiation energy reflected from the protected region.

Means are also provided for allocating a portion of the time occurring between transmitted pulses into a plurality of time segments, each of which segments is long enough to correspond to a plurality of cycles of the analog signal. The detector further includes: means for integrating the plural cycles in each of the time segments to arrive at an integral value for each of the time segments; means for converting the integral values into corresponding digital values; means for storing the digital values in memory; means for comparing the stored digital values obtained from the reflected energy from the first transmitted pulse with the corresponding digital values obtained from the reflected energy of an adjacent second transmitted pulse; means for storing the absolute differences obtained between corresponding integral values for each of the time segments; and, means responsive to predetermined changes in the absolute differences for a predetermined number of time segments for initiating an intrusion c signal in the apparatus.

Filed: 1990-02-12
Abstract: A method is provided for encoding and decoding data to be transmitted over a communication network via transformer coupling. The data is pulse width modulated, and split into separate first and second data streams containing alternate pulses. The first data stream is inverted, and recombined with the second data stream to produce a pulse width modulated bi-polar data signal having an alternating pulse sequence. The data is decoded at the receiver by inverting the pulses of one polarity, and combining them with the pulses of the other polarity to form a pulse width modulated data stream.

Abstract: A method and apparatus for determining the phase and amplitude accuracy of continuous-phase-modulated signals is described. A modulated RF signal generated by a transmitter is down converted to a relatively low intermediate frequency which is filtered and sampled by a high sampling rate analog-to-digital convertor. a digital signal processor processes the digital signals to produce a measured amplitude function and a measured phase function corresponding to the modulated RF signal. From the measured amplitude and phase functions, an ideal phase function corresponding to the modulated RF signal is calculated and synthesized. The ideal phase function is compared to the measured phase function to determine the phase function from which the modulated RF signal phase error and frequency error are computed.
