Latest Patents

Flournoy holds a patent for a frequency hopping spread spectrum receiver. This invention is designed to operate without requiring an independent synchronization source to receive and track a frequency hopping transmitter signal. In search mode, the receiver hops in a reverse direction and at a faster rate than the transmitter's hopping pattern, resulting in quicker signal acquisition times. The receiver utilizes audio data tones from the transmit signal to detect and synchronize with the transmitter signal. Once in track mode, a frequency hopping hysteresis is employed to prevent erroneous detection of signal loss by tracking the transmitter's hopping pattern for several consecutive hops before reverting to search mode.
