An electronic system includes a three terminal device having a light emitting portion and a magnetically sensitive portion. The magnetically sensitive portion is for modulating light emission from the light emitting portion. The device is a spin valve transistor having a light-emitting quantum well in its collector. The device can convert a magnetic digital signal to both an electrical digital signal and an optical digital signal, wherein either or both of these signals can be provided as a device output. The magnetically sensitive portion of the device is formed of a pair of magnetically permeable layers. When the layers are aligned electron current can pass through with sufficient energy to reach a quantum well where they recombine, generating light. The device may be used to read a magnetic storage medium, such as a disk drive. Or it can be used to provide a display or a memory array composed of single device magnetic write, optical read memory cells. Amplification can be provided to the transistor by adjusting the collector base voltage to provide secondary electrons by impact ionization to provide greater electron current and a correspondingly larger optical emission signal.

An electromechanical assembly is provided controlled by voltage across a motor or with an electronic system. The electromechanical assembly includes a control circuit coupled to sense voltage at the motor or within the electronic system, and an electromechanical actuator energized by the voltage sensed by the control circuit. A movable element is movable by the electromechanical actuator from an operational position to a quiesced position when the voltage sensed by the control circuit falls below a quiesced threshold. In certain embodiments, the voltage being sensed is across a motor of an air-moving assembly, which resides within a support structure, or the voltage being sensed is within the electronic system, which resides within the support structure, and the movable element is an interlock element which interlocks to the support structure to prevent removal of one or more components from the structure when sensed voltage is above the quiesced threshold.
