  • Publication number: 20240115259
    Abstract: An apparatus includes a first jaw (16) and a second jaw (618, 718, 900) that cooperate to clamp and staple tissue (90). The second jaw includes a jaw body (620, 720, 902) and a distal tip (619, 719, 906) pivotable relative to the jaw body between a first discrete and a second discrete position. First and second openings (663, 784, 785, 932, 934) are both defined by one of the distal tip or a structure (621, 920) located proximal to the distal tip. A projection (637, 781, 918) is defined by the other of the distal tip or the structure. The projection is positionable within the first opening (663, 785, 932) to releasably retain the distal tip in the first discrete position, and within the second opening (663, 784, 934) to releasably retain the distal tip in the second discrete position.

  • Patent number: 7948264
    Abstract: A new approach for managing turn-on of power islands uses a precharge phase to begin the process of bringing up the island's internal supply voltage, while minimizing transients and associated power-control-logic instability.

  • Patent number: 7875996
    Abstract: An electronic product includes an application specific semiconductor chip (ASIC) device which includes in its circuitry both a linear regulator module configured to be coupled to an optional external capacitance and a capless regulator module configured to be coupled to internal capacitance of the electronic product. Control logic of the ASIC device is responsive to a regulator selection signal for selecting one of the linear regulator module and the capless regulator module for use in powering the ASIC device. The control logic may select the linear regulator module for certain times of operation and the capless regulator module for other times of operation.

  • Patent number: 7859134
    Abstract: A method for operating an electronic product having an application specific semiconductor circuit (ASIC) including in its circuitry both a linear regulator module for use with an optional external capacitance and a capless regulator module coupled to internal capacitance of the product selects a low-power sub-module or high-power sub-module of the capless regulator module for use in a power-up phase of the ASIC. Control logic of the ASIC determines if an external capacitance is present. If so, then the high-power capless sub-module is used during a power-up phase of the ASIC; if not only the low-power capless sub-module is used during the power-up phase of the ASIC. After power-up of the ASIC, the control logic may select the linear regulator module for certain times of operation and the capless regulator module for other times of operation or it may select one or the other for all times of post-power-up operation.

  • Patent number: 7830039
    Abstract: Methods and systems for automatically and/or locally adjusting power-valid detection. In one class of embodiments, local power-on-reset circuits are included in individual power islands; in another class of embodiments, the power-on-reset circuit is automatically reprogrammed, depending on the detected interface voltage level, to use the same circuitry for power-valid detection in either case.

The capless regulator module includes both a low-power sub-module and a high-power sub-module. Control logic of the ASIC is configured to determine if an external capacitance is present. If so, the control logic causes the high-power capless regulator sub-module to be used during a power-up phase of the ASIC; if not, only the low-power capless regulator sub-module is used during the power-up phase of the ASIC.
