  • Patent number: 7154141
    Abstract: A flash EEPROM array having a double-diffused source junction that can be used for source side programming. The flash EEPROM array, when programmed from the source side exhibits fast programming rates. Additionally, source side programming of arrays having different physical characteristics (e.g. transistor cell channel length) exhibit tighter program rate distributions than for the same arrays in which drain side programming is used.

  • Patent number: 6817972
    Abstract: A heart stabilizer that may include a wrist which couples an end effector to a first linkage. The end effector and wrist may be inserted through an incision in the chest of a patient to assist in performing a minimally invasive coronary procedure. The wrist provides dexterity so that the end effector can be placed on the heart to stabilize the same. The end effector may include a pair of paddles that are moved between open and closed positions by a pair of manually actuated levers. The paddles may have cleats that allow sutures to be attached to the stabilizer during a minimally invasive procedure.

  • Patent number: 6567061
    Abstract: A method for operating a display having substrates and a plurality of capacitors formed at predetermined locations between the substrates includes measuring a capacitance for each of the plurality of capacitors, determining a cell gap for each of the plurality of capacitors in response to the capacitance for each of the plurality of capacitors, determining a cell gap relationship between the substrates in response to the cell gap for each of the plurality of capacitors and in response to the predetermined locations on the display, and determining a first intensity compensating value for a first pixel on an active region of the display in response to the cell gap relationship between the substrates and in response to a location of the first pixel on the display.

  • Patent number: 6111433
    Abstract: Method and circuitry for differential output driver with monotonic output transitions. The switching sequence for the output driver transistors of the differential driver changes depending on the direction of the input signal transition. When the input makes a binary transition from high to low, each one of the output driver transistors is switched on or off at a different time based on a first predetermined sequence. When the input makes the opposite binary transition (low to high), each one of the output driver transistors is switched on or off at a different time based on a second predetermined sequence that is different than the first sequence. The predetermined sequences are designed to eliminate any possibility of a glitch or non-monotonic behavior at the output terminals.

  • Patent number: 6052691
    Abstract: A method for maintaining relationships between entities in a computer system, each entity having a plurality nodes, includes the steps of: modifying one of the plurality of nodes; searching for a plurality of dependent nodes from the plurality of nodes coupled to the one node; ordering the plurality of dependent nodes into an order; and evaluating the plurality of dependent nodes in the order.
