Abstract: There is described an emergency lighting system for minimizing power leakage to assure proper operation of an emergency mode. The system comprises a digital addressable lighting bus having digital control lines, a driver, and a lighting control. The driver receives emergency power and provides the emergency power to a light emitter in response to detecting that the digital control lines are shorted. The lighting control receives normal power and includes a relay contact that shorts the digital control lines in response to detecting lack of the normal power. For another aspect, the driver and the lighting control are coupled to lighting control lines, which are either digital or analog control lines. For yet another aspect, a control bypass comprises a power unit, a relay coil, and a relay contact. The relay contact manages outputs of the power unit in response to activation and de-activation by the relay coil.

Abstract: A computer image generation system is described which models objects without the necessity of linear edges. The system is adaptable for dynamic (real time) image generation from a compact model base for use in, for example, flight training systems. Scene content is enhanced by a novel texture generator. The system is designed for use with standard video display equipment.
