Abstract: A system and method of operating a twin-transistor single bit multi-time programmable memory cell to provide a high gain, sensing scheme for small signals. The memory cell includes a pair of a first transistor and a second transistor providing a differential signal output. The first transistor of the memory cell couples a first circuit leg having a first current source load transistor and the second transistor couples a second circuit leg having a second current source load transistor. A programmed value is represented by a voltage threshold shift in one of the first or second transistors. A feedback circuit receives one of: a first signal or a second signal of the differential signals, and generates, in response, a feedback signal which is simultaneously applied to bias each current source load transistor in each the first and second circuit legs to amplify a voltage differential between the differential signal outputs.

Abstract: A light fixture assembly includes a light source, a reflector and a shield. The light source emits a beam of light. The reflector directs at least a portion of the beam of light emitted from the light source. The shield is positioned in the reflector to intercept at least a portion of the light emitted from the light source.
