Patents by Inventor Robert Sythes

Robert Sythes 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).

Method of and apparatus for detecting open circuit conditions at an input to a signal chain and for detecting channel imbalance in a differential signal chain

Patent number: 10476458

Abstract: It is often desirable to distinguish between an open circuit condition and a no signal condition. In both cases an input signal may be absent, but only one of these events represents a failure of the equipment. The present disclosure provides a way to use a difference amplifier to check for open circuit events, without requiring additional circuitry at the input of the amplifier.
