Abstract: Provided is an illuminated reticle assembly for an optical aiming device. The assembly includes a reticle plate has a first surface on which a physical reticle pattern is applied. A laser light source is configured to project a beam of laser light into the reticle plate at a first angle and toward an inner side of a second surface at an angle of incidence that directs a reflected beam of laser light toward at least a selected portion of the physical reticle pattern. The reflected laser light illuminates the at least selected portion of the physical reticle pattern.

Abstract: An optical projection system (12) for a weapon system aiming scope (10) having at least objective and ocular lenses (24, 26) defining an optical path through which a target image (30) is observed. The projection system (12) includes a primary beamsplitter (62) positioned in the optical path, a secondary beamsplitter (64) positioned adjacent the primary beamsplitter (62) and off the optical path, a micro-display (60) that provides a data image (38, 88) containing targeting information (100, 101, 102, 104, 106, 108, 110, 112), and an illumination source (52). The illumination source (52) generates light directed through the secondary beamsplitter (64) to illuminate and reflect off the micro-display (60) so as to define a reflected data image (88), and the secondary beamsplitter (64) directs the reflected data image (88) into the primary beamsplitter (62).

Abstract: A method and apparatus for externally modifying the operation of a closed loop electronic fuel injection control system that is normally used with a standard oxygen sensor, which method and apparatus includes replacing the standard oxygen sensor with a wide band oxygen sensor. The signal from the wide band oxygen sensor is processed in a first signal-conditioning module and coupled to the input of the electronic fuel injection control system. The first signal-conditioning module simulates the appearance of a standard oxygen sensor to the electronic fuel injection control system. In a second embodiment, a method and apparatus for externally modifying the operation of a closed loop electronic fuel injection control system that is normally used with a wide band oxygen sensor, includes intercepting the signal from the wide band oxygen sensor in a second signal-conditioning module.
