Abstract: A vehicle headlamp using a high-power LED light source, receiving power regulated by a driver circuit, is mounted in a housing and covered at least in part by a light transmissive cover using a construction by which heat developed by the driver circuit (current regulator) is conducted to the light transmissive cover, thereby heating the transparent cover and so retarding the formation or accumulation of ice and snow on the light transmissive cover.

Abstract: A headlamp for a vehicle (air, land or sea) providing a planar array of infrared (IR) light-emitting diodes (LEDs) and visible light LEDs, and arranged and mounted within a housing so as to provide for cooling of the LEDs without forced convection, by conducting heat from the LEDs to protruding cooling fins. A switch system is also provided, for enabling either the visible light or the infrared light, and for selecting a high-beam or low-beam pattern. The beam pattern is provided in some embodiments so as to meet US Federal Motor Vehicle standards.

Abstract: An image stabilization or vibration reduction facility for a riflescope and firearm has a transparent optical element that refracts incoming rays passing based on motion, to provide a stabilized image, which is transmitted to a user along an optical path of a rifle scope. A feedback transducer connected an output signal from the stabilization facility indicates a characteristic of the output signal. The transducer may be a second reticle that moves based on motion of the riflescope to indicate the degree of deflection by the stabilization facility, and may illuminate when the stabilization facility is in a neutral condition without deflection. The rifle may include a trigger block the prevents trigger operation until a neutral condition is detected.
