  • Patent number: 6815266
    Abstract: A method for manufacturing sidewall contacts for a chalcogenide memory device is disclosed. A first conductive layer is initially deposited on top of a first oxide layer. The first conductive layer is then patterned and etched using well-known processes. Next, a second oxide layer is deposited on top of the first conductive layer and the first oxide layer. An opening is then etched into at least the first oxide layer such that a portion of the first conductive layer is exposed within the opening. The exposed portion of the first conductive layer is then removed from the opening such that the first conductive layer is flush with an inner surface or sidewall of the opening. After depositing a chalcogenide layer on top of the second oxide layer, filling the opening with chalcogenide, a second conductive layer is deposited on top of the chalcogenide layer.

  • Patent number: 6810343
    Abstract: A method and system for monitoring service quality in a restaurant are disclosed. Multiple sensor modules are installed at each table of a restaurant for detecting restaurant customer service related information. The detected restaurant customer service related information is transmitted, preferably, over-the-air to a central computer unit having a receiver for receiving the detected restaurant customer service related information transmitted by the sensor modules over-the-air. A display monitor, coupled to the central computer unit, can be utilized to display the detected restaurant customer service related information received by the receiver to a restaurant manager in a real-time basis regardless of whether the restaurant manager is present at the restaurant or at a remote location.

  • Patent number: 6763006
    Abstract: A method and apparatus for controlling uplink transmission power in a satellite communication system is disclosed. The satellite communication system includes a satellite and one or more earth stations, one of which serving as a control station. The satellite can receive uplink signals from any one of the earth stations and retransmits the uplink signals as downlink signals, along with a beacon signal. The control station measures the power of the downlink signals and the beacon signal received from the satellite, and also measures the noise power near the beacon signal. From these measurements, the control station determines an appropriate gain value of the power for uplink transmissions for each of the earth stations.

  • Patent number: 6717233
    Abstract: A method for fabricating resistors within a semiconductor integrated circuit device is disclosed. A resistor is fabricated by first depositing a passivation layer on a semiconductor substrate having multiple transistors previously formed thereon. Next, a first contact window and a second contact window are formed through the first passivation layer at a first contact location and a second contact location, respectively. The first and second contact windows are then filled with metal, such as tungsten, and the metal at the first and second contact windows is planarized to form a first bottom contact and a second bottom contact, respectively. A resistive film, such as polysilicon, subsequently deposited over the first passivation layer. Next, a second passivation layer is formed over the resistive film.

  • Patent number: 6683932
    Abstract: A single-event upset immune frequency divider circuit is disclosed. The single-event upset immune frequency divider circuit includes a dual-path shift register, a dual-path multiplexor, and a summing circuit. The dual-path shift register has a clock input, one signal input pair and multiple signal output pairs. The dual-path multiplexor has multiple signal input pairs and one output pair. The signal input pairs of the dual-path multiplexor are respectively connected to the signal output pairs of the dual-input shift register. The dual-path multiplexor selects one of the signal output pairs of the dual-path shift register for feeding back into the signal input pair of the dual-path shift register. The summing circuit then sums the signal input pair of the dual-path shift register to generate an output clock signal that is a fraction of the frequency of an input clock signal at the clock input of the dual-path shift register.

  • Patent number: 6648230
    Abstract: A method and apparatus for evaluating a confidence level of a decoded barcode value is disclosed. A digit score is assigned to a digit within a barcode. When decoding the barcode, if a deduction is required to decode the digit, then the digit score for the digit is reduced accordingly. After all the digits within the barcode have been decoded, a total score of a decoded barcode value can be determined by adding all the digit scores for all the digits within the barcode. The total score of the decoded barcode value is reduced if a checksum is used to ascertain the value of any digit within the barcode. The decoded barcode value can be accepted only if the total score exceeds a predetermined value.

  • Patent number: 6609235
    Abstract: A method for providing a fill pattern for integrated circuit designs is disclosed. A keepout file having keepout data is generated from a chip design layout file having chip design layout data. The keepout file includes a map of areas of an integrated circuit design where fill patterns cannot be placed. The map of areas from the keepout file is then overlaid with a fill pattern to yield a fill-pattern file. Fill patterns from the fill-pattern file is removed from locations that coincide with locations as defined by the keepout data to yield a final-fill file with crucial fill pattern data. The crucial fill pattern data from the final-fill file is overlaid on the design layout data in the chip design layout file to yield a complete design layout file. Finally, the design rule integrity and logical to physical correspondence of the complete design layout file is verified.
