  • Patent number: 7218437
    Abstract: A method and system for generating colors efficiently. In one embodiment, a start signal for a primary color subcycle may be received. A primary light source used to drive the primary color may be activated if there is data in the primary color's buffer. The primary light source may be deactivated during the primary color subcycle if there is no data in the primary color's buffer. In another embodiment, a highest amplitude signal for one of a plurality of primary colors may be normalized. A drive light source intensity may be adjusted to a percentage of a maximum intensity where the percentage corresponds to a content of the normalized primary color in a frame. The amplitude of all but the normalized primary color may be adjusted proportionally. In another embodiment, a maximum intensity for a light source intensity may be set to a first value. A maximum pixel intensity for each of a plurality of pixels may be set to a second value.

  • Patent number: 7042618
    Abstract: A circuit for implementing a registration-free, contiguous conductive plane. A circuit may include a plurality of conductive structures in a first plane. The circuit may further include a contiguous conductive equipotential surface in a second plane parallel to the first plane. The circuit may further include activation means configured to adjust an electric field between the first and second planes thereby activating one or more structures in the first plane by increasing a potential difference between the first and second planes to a threshold level deemed to constitute an active state. The circuit may further include deactivation means configured to adjust the electric field between the first and second planes thereby deactivating one or more structures in the first plane by decreasing the potential difference between the first and second planes below a threshold level deemed to constitute a deactivation state.

  • Patent number: 5319491
    Abstract: An optical display in which at least one pixel is selectively controlled to shutter light out of a light guidance substrate by violating the light guidance conditions of the medium, and in which a full color palette is provided by multiplexing the three additive primaries in relation to the inherent limitations of the human eye.

  • Patent number: 4862400
    Abstract: A bus assembly for a microcomputer comprising a motherboard having a data bus of the standard type, which bus assembly comprises means for mounting a plurality of daughtercards at an acute angle with respect to the motherboard. The bus assembly further comprises a bus extension card adapted to plug into the edge card connectors of the motherboard data bus so as to be retained parallel to the motherboard. The bus extension card is provided with a plurality of edge card connectors disposed at an acute angle with respect to the card and thus at an acute angle with respect to the motherboard.
