  • Patent number: 6900777
    Abstract: A video interface linking a base station with a remote display, e.g., a head-mounted display, converts input video signals from NTSC or PAL formats into modulated video signals containing repetitive sequences of frame times with embedded audio and control signals. Each frame time includes equal consecutive color field times. Frame rates are converted by inserting selected repeating color frames into the datastream. Bursts of image information occupy a portion of each field time. During each data burst, the display is loaded with pixel luminance data. Between bursts, the display is illuminated by a color LED. Two video displays can be driven alternately, i.e., the first display loads while the second is illuminated. The modulated video signal can travel through the atmosphere on an infrared (IR) beam with a wavelength between 700 nm and 1100 nm. In one embodiment, the beam is scattered from a diffuse reflecting surface. Alternatively, the beam is emitted from an array of infrared light emitting diodes (LEDs).

  • Patent number: 6219186
    Abstract: Low-cost plastic optics allow biocular viewing of video images with a single electro-optic display device. Folded and unfolded dual off-axis configurations use collimated illumination and intermediate imaging optics to fill both eyepieces from a single display device without requiring beamsplitters. Multiple illumination schemes provide either monochrome or color, either two-dimensional or time-sequential true stereographic presentation. Light from multicolor sources is superimposed using dichroic mirrors. A display field lens proximate to the display surface collimates the illumination beam. A shaping lens provides substantially uniform illumination of the display surface. An aperture stop improves image quality by blending sub-pixel higher order spatial harmonics from the display device. Offsetting color over- and under-correction of individual optical elements provides overall chromatic correction with minimal optical complexity.

  • Patent number: 6040946
    Abstract: Low-cost complex plastic optics allow biocular viewing of video images generated by a single electro-optic display device, such as in a head-mounted display (HMD) for commercial or medical viewing applications. A dual off-axis configuration uses nearly collimated illumination optics and intermediate imaging optics to fill both eyepieces from a single display device without the need for a beamsplitter. Multiple illumination schemes are provided for either monochrome or color, and in either two-dimensional or time-sequential true stereographic presentation. Light from multicolor sources is superimposed, mixed, and homogenized by mixing light cones with diffractive collectors. Offsetting color overcorrection and undercorrection of individual optical elements achieves overall chromatic correction with minimal optical element complexity; A wireless video signal interface eliminates excess cabling.

  • Patent number: 4403644
    Abstract: A compact heat storage system for over heated rooms in which a high value thermal mass is mounted in a forced air flow path formed within a refrigeration heat exchanger loop including a condenser at the inlet and an evaporator at the outlet interconnected with a compressor and an expansion control. The thermal mass is preferably PCM or the equivalent. In the heat storage mode, with the compressor in operation, the air flow is heated at the condenser so that the heated incoming air passes through the thermal mass with high thermal difference resulting in better thermal transfer efficiency. After passage, the air has been cooled by thermal transfer with the thermal mass and is further cooled by the evaporator and then passed back into the room significantly cooler than when entered.When the room space needs heat from the system, the fan is operated without the compressor to pull the cool air from the room through the thermal mass to heat the same.
