    摘要： A low power clocking apparatus and method is used to reduce power consumption by an electronic system or an integrated circuit that is coupled to an external system via a system bus which is configured to selectively transmit or receive signals from the electronic system or integrated circuit. The electronic system or integrated circuit includes a plurality of sub-circuits. Each sub-circuit is configured to operate under control of a clock signal and further includes an apparatus for keeping or rejecting the clock signal. Once each sub-circuit within the electronic system or integrated circuit rejects the clock signal, an integral arbiter circuit disables the clock signal to all the sub-circuits. The arbiter circuit continuously monitors the system bus. Upon detecting that the sub-circuits will require the clock signal, the arbiter will re-enable the clock signal to all of the sub-circuits.

    摘要： The design and implementation of a low power CMOS bi-directional I/O buffer that translates low voltage core logic level signals into the highest logic level signals to drive the final output stage which outputs a selectable logic level signal. The buffer further translates input signals of a variety of logic levels into low voltage core logic level signals. In either case, AC and DC power consumption is minimized in a mixed power supply environment that requires voltage translation to represent the proper binary logic levels. An multivoltage I/O buffer having multiple input-receiving NOR gates is also described. The NOR gates of the multivoltage I/O buffer having triggering levels optimized for differing core voltage levels. Also described is a host adapted system for interfacing between and removable peripheral card and a host computer. The host adaptor includes an integrated circuit employing the multivoltage bi-directional I/O buffer.

    摘要： A method and apparatus for maintaining the voltage level of data signals supplied to an integrated circuit, such as a PCMCIA card, at the same level as power also provided to the integrated circuit. Circuitry for maintaining the voltages at the same level is preferably embodied within a system having a card controller integrated circuit, a power supply, and a peripheral card socket for receiving a removable PCMCIA card. The power supply is controlled by the card controller to provide power to the PCMCIA card through the card socket at a voltage level matching internal voltage requirements of the PCMCIA card. The card controller is connected directly to the PCMCIA card by a signal transmission line. Circuitry is provided for ensuring that the voltage of data signals transmitted along the data bus line to the PCMCIA card substantially match the voltage of power provided from the power supply to the PCMCIA card along a power supply line. In this manner, damage resulting from a power mismatch within the PCMCIA card is avoided.

    摘要： Video information is simultaneously generated for presentation on multiple displays by a display system including a video memory having a plurality of addressable storage locations, each storage location providing for the storage of data representing a component of an independent displayable image and a video controller providing a plurality of output display control and data signals connectable to a respective plurality of video displays. The video controller accesses the video memory in a predetermined addressing pattern so as to access a sequence of the components corresponding to a plurality of the independent displayable images. The video controller, in turn, generates the plurality of output display control and data signals whereby the sequence of the components provided by way of each of the plurality of the output display control and data signals corresponds to a respective one of the independent displayable images.

    摘要： The amount of time that a row of pixels in a flat-panel display is illuminated is modulated from frame-to-frame and from row-to-row. Pixels in rows that are on for a longer period of time appear brighter than pixels in rows that are on for shorter periods of time. Such line modulation is combined with frame-rate-cycling (FRC) to dramatically increase the number of gray scales that can be generated for any given number of frames in a FRC cycle, and with phase-offsetting to keep the frame period constant and to reduce flicker. An N-frame FRC cycle that previously generated N+1 gray scales now produces a full 2.sup.N gray scales. The total pixel-on time over the N frame cycle depends not just on how many frames the pixel is on, but on which frames the pixel is on. Since each row in each frame in the FRC cycle is on for a different amount of time, aliasing of the frames is greatly lessened or no longer occurs. A line modulation buffer and speeding up the pixel clock to the panel allow for greater modulation.

    摘要： A method for transmitting audio/video data from a web site to viewing devices, e.g., personal digital assistant, cellular phone. The method includes prompting at least two selections on a viewing device, which is coupled to a worldwide network of computers through a wireless connection. The two selections comprises a first selection for an automatic set up (441) and a second selection for a manual set up. The method includes selecting either the first selection or the second selection and transmitting the selection to a web site, which is coupled to a source of audio/video data, e.g., camera. If the first selection is entered, a web page based upon a viewer's profile of the viewing device is formed and transmitted to the viewing device. Alternatively, if the second selection is entered, a form page of selectable parameters is formed and transmitted from the web site to the viewing device. Next, audio/video data from the web site is transmitted to the viewing device based upon the first selection or the second selection.
