A controller and a method is provided for controlling a capacitance of an LC circuit having a circuit frequency including, a variable capacitor to couple with an external inductor as part of an LC circuit, a target value, a spread spectrum function to generate an adjustment value, and a circuit to poll the target value, call the spread spectrum function, and set a capacitance of the variable capacitor based on the sum of the target value and the adjustment value.

Apparatus and methods for reporting data and remotely monitoring and controlling a stationary mechanical or electrical device having a device controller. The apparatus and methods employ a remote annunciator comprising a communication interface for communicating with the device controller, a computer processor for polling the device controller to monitor operational data, conditions, and alarms reported by the device controller, a graphical display for displaying visual indicators indicative of the operational data, conditions, and alarms, a cellular or satellite radio for communicating the operational data, conditions, and alarms to a remotely-located monitoring and control system comprising a web-accessible database and a compatible cellular or satellite radio. The device controller is polled via the monitoring and control system and/or remote annunciator to monitor device parameters and status, and remotely control the device.

A video stream is encoded using spread spectrum video transport and sent as an analog signal to a display of a VR visor where a decoder integrated with a source driver decodes the analog signal and drives the display. The analog signal is sent wirelessly to the display where it is received, converted to wired format, decoded and displayed. A wireless SSVT analog signal is received at the headset processor and forwarded to the VR visor for reception, conversion, decoding and display. A wireless SSVT analog signal is received at the processor, converted to wired format, sent wirelessly to the display where it is received at a receiver, converted to wired format, decoded and displayed. A video stream is stored in persistent storage on the headset processor using SSVT encoding. The decoder integrated with a source driver of a display is implemented directly on the glass of the display panel.
