Abstract: A plural color lighting device incorporating a plurality of LED emitters each emitting a different color of light upon being energized by a power supply. A color changer having an indexing position for each LED emitter for activating a related switch and connecting the power supply to the LED emitter while concurrently positioning a light concentrating optic about the LED emitter to concentrate the light emitted from that LED emitter. The plural color lighting device therefore permitting the user to easily select light of any one color from a plurality of colors and have that light efficiently concentrated about the axis of the light concentrating optic.

Abstract: A color changing lighting device incorporating a plurality of led emitters having a plurality of colors each emitting a distinct color of light upon being energized by a power supply. A color changer having an indexing position for each led emitter for activating a related switch and connecting a power supply to the led emitter while concurrently positioning a light concentrating lens about the led emitter to concentrate the light emitted from that led emitter. The color changing lighting device therefore permitting the user to easily select light of a distinct color from a plurality of colors and have that light efficiently concentrated about the axis of the light concentrating lens.

Abstract: The present invention incorporates a system for varying the output signal and regulating the power consumed by an electrical device. It achieves its purpose by moving a magnet relative to a Hall effect sensor which is responsive to an intersecting magnetic field. The Hall effect sensor creates an electrical output signal which determines the input signal of an output element of the device. The electrical Hall effect sensor signal thereby controls the output signal emitted by the electrical output element. The magnet is moved using a movable element. Since the location and movement of the magnet regulates the Hall effect sensor output signal, the output signal of the electrical device as well as its rate of change are regulated using the movable element. In order to conserve power the Hall effect sensor element is usually not energized when the device is in the "off" mode.

Abstract: A navigation device for personal use includes a face mask with a transparent window for binocular vision when the device is worn by the user. The face mask has a directional indicator attachement with a multiplicity of symbols to identify the directional orientation of the mask. The directional indicator is attached at a stable location and distance for continuous availability of direct binocular viewing.
