Latest Patents

Johnson holds a patent for an optical communication system. This system includes an optical bus and multiple terminal devices connected to the bus. It features a reference signal generator that propagates a reference signal through the bus, allowing terminal devices to select from a predetermined number of frequency distinct communications channels. The reference signal is frequency swept between two fixed frequencies and is introduced onto the system bus, along with a synchronization signal. Each terminal device detects the moment the swept reference frequency passes through one of the resonant modes of its bus tap resonator, determining the elapsed time from the synchronization signal. The bus tap resonator can be controlled by adjusting its operating temperature, ensuring that the reference frequency aligns with the resonant mode at a selected time.
