Barry M. Kaufman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10158400
    Abstract: A power line carrier fault detection system includes a forward signal generator configured to transmit a carrier signal to a power line. A directional coupler couples the forward signal generator to the power line. The directional coupler is configured to separate forward and reflected power. A frequency selective filter associated with the directional coupler is configured to meter frequencies within a band of a transmitted carrier signal and to attenuate out of band signals.
    Type: Grant

  • Patent number: 5598420
    Abstract: Method and System for providing a gateway between a communications device and data receiving device which corrects a data signal produced by the communications device by reducing the data errors produced by the communications device by replacing the data signal with a guard signal when the error exceeds a bandwidth and by controlling the communications device so that it provides predictable propagation delays by resetting an adaptive component of the communications device to perform a major convergence and by setting the coefficients used by the adaptive component to predetermined initial values.

  • Patent number: 4160121
    Abstract: A frequency shift keyed (FSK) generator producing an output tone frequency which is determined by the output frequency of a digital frequency synthesizer responsive to a control signal. The square wave output of the synthesizer is filtered to a sinewave by an active tracking bandpass filter whose operating frequency is automatically switched to the output frequency of the synthesizer.

  • Patent number: 4015220
    Abstract: A frequency shift keyed (FSK) generator producing an output frequency which is determined by gating through a selected one of a plurality of crystal controlled oscillators. The oscillator output is divided by a digital frequency divider to the operating tone frequency. The square wave output of the divider is filtered to a sinewave by an active tracking bandpass filter which is instantaneously switched to the operating frequency simultaneously with the selection of the appropriate crystal controlled oscillator.

  • Patent number: 4001702
    Abstract: A high speed arrangement for simultaneously demodulating the AM and FM information coming in on a tone frequency carrier. In the case of the incoming tone signal being only FM modulated, the FM demodulator extracts the data whereas the AM demodulator provides an output which can be used to squelch the FM demodulated data channel when noise or interference reaches a predetermined level.
