  • Patent number: 5176442
    Abstract: A light projector is presented including a wireless power coupling mechanism and infra-red communications coupling mechanism which provide a portion of the projector with the capability of complete full-circle rotation about its pan-axis. A stationary base is provided which includes a first transmitter and receiver means for transmitting control signals to and receiving information signals from a second transmitter and receiver means on the rotating portion of the projector. A pan-axis shaft includes the second transmitter and receiver means for transmitting information signals to and receiving control signals from the transmitter-receiver means on the stationary base, and is operative to rotate the rotatable portion of the projector. The infra-red coupling mechanism and wireless power coupling mechanism eliminate the need for hard-wiring between the base and rotating portion of the projector, greatly facilitating continuous and efficient motion thereof.

  • Patent number: 5147129
    Abstract: The visual attractiveness of a variety of otherwise-autonomous articles may be significantly enhanced through the inclusion of an apertured, internally light-transmissive, peripherally light-intrareflective panel which is edge-illuminated and energized by elements self-contained within the article body. Article apertures of distributed area, point size or both may be thusly illuminated. Distributed-area display effects may be enhanced through aperture-aligned light-concentrative discontinuities formed in the panel. Enhancement of point-display effects may similarly be achieved through point-aperture-aligned, light-concentrative point discontinuities likewise formed in the panel. Point effects may also be enhanced through the employment of an end-illuminated, aperture-aligned, point-discontinuous optical fiber in conjunction with a subject apertured panel. Bi-directional display effects in subject autonomous articles may be achieved by means of a layered panel having oppositely-projective surfaces.

  • Patent number: 5145247
    Abstract: A down lighting system for elevator cabs and the like includes halogen lights in standard and emergency light fixtures. Both types of fixtures are connected to the ceiling by a clamp arrangement which is universally adaptable to a wide variety of ceiling types without changing the light housing dimensions. The clamp arrangement fastens light housings against rotation with respect to the ceiling and it is adjustable to different height ceiling configurations merely by connection to different vertical positions of the outer surface of the fixture. The standard fixture includes a halogen bulb with its own reflector. The emergency lighting fixture includes a halogen bulb/reflector unit with the emergency self focusing bulbs concentrically spaced around it. Both light sources pass focused light directly into the space below the ceiling for meeting test point candle power requirements.

  • Patent number: 5143433
    Abstract: This invention presents a way to provide night vision viewing compatibility of backlit electrooptic modulated light valve or LCD displays designed for daylight viewing. Liquid crystal displays (LCD) designed with backlighting systems which provide a high brightness, good contrast display under daylight conditions are inappropriate for use in dark, night time conditions where viewing of the display is desired utilizing electronic night vision equipment. This invention describes improvements to standard backlighting displays which through the utilization of arrays of low-level intensity light sources such as secondary fluorescent light sources, miniature incandescent lamps or light emitting diodes, the general means used in daylight vision can be turned off and the secondary low-level lighting sources achieve a minimum intensity acceptable for night vision electronic viewing.
