  • Patent number: 5852437
    Abstract: A two-way wireless local transmission system integrates computer and television user interfaces. A television set-top device includes a separate transmitter and receiver. The transmitter converts an audio and video signal into a modulated signal within the 902-928 MHz frequency band and transmits the modulated signal to a receiver associated with a computer peripheral device. The receiver downconverts the modulated signal and processes the signal within the computer. The computer processed signal is then sent by a transmitter in the computer peripheral device to the receiver in the set-top device, which provides the signal to a television receiver which displays images in response to the received signals.

  • Patent number: 5844557
    Abstract: The system and method of the present invention for detecting screen hotspots provides a graphical user interface environment that enables a user to select screen hotspots that are graphically represented by complex shapes and multiple colors. The use of complex-shaped multi-colored hotspots enables the creation of more realistic graphical representations implementing screen hotspots. Monochrome bitmaps, or masks, are created for each and every hotspot of each and every window view that may be displayed on a screen. Each mask defines valid coordinates for the corresponding hotspots such that, so long as a cursor is located on a valid coordinate, the user can select that hotspot, regardless of the complex shape or multiple colors used to graphically represent the hotspot.

  • Patent number: 5809559
    Abstract: A method and apparatus using a virtual addressing buffer circuit afford address mapping and control flexibility to provide a unique opportunity for device emulation and software debugging. The method permits the emulation of a device which is physically not present in a CPU controlled system utilizing a virtual addressing buffer circuit. The method includes the step of storing a match address which corresponds to an address location of the device. The virtual addressing buffer intercepts an address request from a CPU for the address location of the device. Bits of the requested address which are not relevant to a determination of whether the requested address matches the match address are filtered out to produce a filtered request address. The filtered request address is compared with the match address, and a match indicator is activated when the filtered requested address matches the match address.

  • Patent number: 5779502
    Abstract: In an integrated circuit socket an integrating capacitor filter carried on a mylar film or integral with said socket incorporated into the top of an integrated circuit socket electrically connected to the voltage and ground connecting pins or electrodes of the integrated circuit in as close as proximity to the entry point into the integrated circuit as is possible. This reduces the lead distance between the entry point in the integrated circuit including CPU integrated circuits at both the voltage and ground connection and the capacitive element to a minimum and minimizes interference in the power source by minimizing inductance in capacitor leads experienced in high speed electrical circuits. It is particular useful in minimizing electrical interference in the voltage applied to CPU by incorporating the capacitive element directly into the CPU socket so that it is electrically coupled between the voltage pin and the ground pin of the CPU in close proximity to the entry point in the CPU.

  • Patent number: 5778446
    Abstract: A rule-based DRAM controller asserts memory access and control signals (including the CAS, RAS, WE, and address data signals) based upon pre-specified control rules. Certain pre-specified rules, or conditions, are used by the DRAM controller to determine the timing and sequence of the memory accessing and control signals output by the DRAM controller. The control rules for asserting the various memory accessing signals are advantageously implemented as logic within the DRAM controller, while the conditions and qualification for the control rules are provided from various monitoring signals and independently operating timing modules which keep track of the DRAM and controller states. Based upon these rules and conditions, the request inputs to the DRAM controller are interpreted to provide optimum access speed to the DRAM.

  • Patent number: 5777854
    Abstract: A computer system chassis, including a base and a cover, implements an improved grounding system by integrally forming a plurality of flexible protruding contacts into predetermined contact regions throughout the base during the metal punching manufacturing phase of the chassis base blank. In this way, when the base and cover are attached to each other, the size of any gaps which may form in these contact regions, as a result of warpage or design tolerances, are reduced. This is due to the number of mechanical contacts being made by the plurality of flexible contacts which protrude and extend across these gaps and connect the base to the cover. In addition to reducing the size of these gaps, the flexible contacts provide an improved electrical grounding to the cover by increasing metal-to-metal contact between the cover and the base, both of which reduce EMI emissions from the computer system chassis.
