  • Patent number: 4569019
    Abstract: Programmable I/O (input/output) interface circuitry provides video and audio signals, needed for a video computer/game, to a commercial color television type display/monitor and may be implemented in HMOS, (H type metal oxide semiconductor) large-scale-integrated circuitry. The system architecture allows for reduced chip count, and improved reliability while providing adequate synchronization pulses, luminance level signals, chrominance phase shift signals, raster control and cursor control video and three independently controlled audio voices. A software selectable keyboard latch input, plural speed processing for faster operation when outside the active display area or during blanking, all system control signals necessary for system operation and 3 independently controlled interrupt generating timers are also provided.

  • Patent number: 4561659
    Abstract: A display control circuit provides the logical determination of display information for each dot point of a color television or other display device used in connection with an electronic game for displaying up to eight "targets", as well as background information, according to a preassigned software defined priority whereby hardware circuitry encodes background-to-target software information and then decodes all game display circuit information to generate a color display code to the color television-type display device, this hardware utilizing a reduced space on a large scale integrated (LSI) circuit.

  • Patent number: 4551682
    Abstract: A solid-state, digital logic, sine-cosine generator is provided for use in color television signal generators which contributes little or no phase shift or drift, whereby an input frequency of four times the color burst rate is used, and a first divide by two shift register operates upon that input signal frequency while a second divide by two shift register is used to obtain the proper color burst frequency as well as the 90.degree. relationship for the sine and cosine signals; a series of integrators then converts the digital "square" waves to triangular and then sinusoidal signals.

  • Patent number: 4507004
    Abstract: A utility brush, usable in car or window washing, includes a hollow, cylindrical handle which communicates through a passageway to a brush head, and has been improved whereby a piston is manually operated within the cylinder, by a handle extending through the side wall of the cylinder, the movement of this handle along a slot in the cylinder definingthe stroke of the piston; a collapsible diaphragm-type valve at the passageway connection end of the cylinder opens to allow a large flow of fluid on the piston vacuum stroke and is otherwise closed to divert fluid flow through small by-pass ports leading to the brush head passageway.
