An optical transformer includes a light source and an array of photovoltaic cells optically coupled to the light source, where at least a portion of the photovoltaic cells are connected in series. An optical connector such as a waveguide or an optical fiber may be disposed between an output of the light source and an input of the array of photovoltaic cells. Configured to generate a high voltage output, the optical transformer may be configured to power a device such as an actuator that provides a tunable displacement as a function of voltage.

Optical transformer

A communication system where first and second devices communicate concurrently and bidirectionally over a single wire and a ground. The second device can be a computing device having a powered component which requires a certain power output, for instance, and the first device may be a power supply unit. The second device provides a signal on a control line (the single wire) which is characterized by a frequency, pulse width, duty cycle and/or an amplitude which is associated with a message from the second device. The first device recognizes the message in the signal and invokes a corresponding function, such as by enabling a corresponding power supply. The power supply provides power to the second device via a separate power line. Further, the first device modifies the signal, without adding power, to provide a message from the first device, concurrent with the message from the second device.

Single wire concurrent bi-directional communication for PSU

Detecting a connection between two circuits utilizing a high-speed interface. Interface circuitry internal to a computing device performs an initialization process between two processors automatically to determine the state of the interface connection. Test circuitry retrieves the interface state from the interface circuitry. Neither the configuration process, the interface circuitry or the test circuitry require full functionality of an IC on which they reside in order to operate.
