  • Patent number: 9168594
    Abstract: A toolholder includes an absorber mass externally mounted to a body portion of the toolholder. A spacer is disposed within one or more recesses formed in a bottom wall of the absorber mass. One or more resilient members are disposed between the body portion and the absorber mass, and one or more resilient members are disposed between the absorber mass and the spacer. A clamping bolt passes through each spacer, through the absorber mass and is threaded into the body portion of the toolholder. A rigidity of the one or more resilient members can be selectively adjusted by the clamping bolts so as to tune the absorber mass for optimum dampening of vibration of the toolholder.

  • Publication number: 20150279596
    Abstract: A thermal cut-off device includes a plastic base, two electrodes, a temperature sensing element, and a plastic cover that fits over the base. The temperature sensing element is curved downward, and may be a bimetal or a trimetal. When the device is subject to an over-temperature condition, the orientation of the curve flips such that the temperature sensing element is then curved upward. When the temperature sensing element is curved upward, it lifts an arm of one of the electrodes, which severs the electrical connection between the electrodes. In this manner the device shuts off during an over-temperature condition in order to protect the circuit in which the device is installed. To prevent corrosion of the temperature sensing element, a first moisture insulation layer is applied to the outer surface of the thermal cut-off device. The moisture insulation layer may be an epoxy adhesive or a UV/visible light-cured adhesive or light/heat cured adhesive.

  • Patent number: 8533643
    Abstract: A method and apparatus for performing template-based classification of a circuit design are disclosed. A template file is read that defines a plurality of channel-connected-region (CCR) templates. A graph is formatted for each of the CCR templates. A plurality of CCRs are identified based on a partitioned netlist file that defines a given circuit design. A graph is generated for each of the identified CCRs. A matching CCR template graph is identified for each generated CCR graph. The template file may further defines super-CCR templates, and a graph may be formatted for each of the super-CCR templates. All possible combinations of CCRs and previously-matched super-CCRs that are candidates to match the formatted super-CCR template graph may be determined in an interative manner, for each formatted super-CCR template graph. A determination may be made as to which of the candidate combinations actually match the formatted super-CCR template graph.

  • Patent number: 8156466
    Abstract: An improved method for interconnect delay analysis for VLSI circuits reduces a parasitic graph for moment computation by eliminating one or more nodes in the graph. the elimination process is performed based upon the degree of the nodes. By eliminating nodes in this fashion, the computation complexity is significantly reduced. With this elimination process, resistor loops and crossed loops can also be solved. The order in which the nodes are eliminated is optimized using the depth-first-search method on the parasitic graphs, further reducing the computation complexity. The method provides a consistent functional interface, applicable to different circuit model structures. In addition, the method accounts for coupling capacitance between interconnects.

  • Patent number: 7661083
    Abstract: A method of determining whether voltage from an aggressor net exceeds a voltage threshold on a victim net design in an integrated circuit design. Probabilistic noise from the aggressor net on the victim net is calculated. The probabilistic noise is checked against the voltage threshold, and the victim net design is passed when the probabilistic noise does not exceed the voltage threshold. When the probabilistic noise does exceed the threshold, then an effective noise at a desired mean time to failure is computed, and the effective noise is checked against the voltage threshold. The victim net design is passed when the effective noise does not exceed the voltage threshold, and failed when the effective noise does exceed the threshold.

  • Patent number: 7260801
    Abstract: A method of computing output delay in a mathematical model of an integrated circuit by sorting cells of original design of an the integrated circuit in a topological order. The original output delays for the sorted cells in the original design are computed in the topological order, to produce original output ramp times. The original output ramp times are propagated and original output delays are computed, and the original output ramp time and original output load for each cell is stored. The cells of the original design are modified to produce a modified design. For each modified cell in the topological order, a new output delay and a new output ramp time are computed and compared to the original output ramp time on the modified cell. When the new output ramp time substantially equals the original output ramp time for a modified cell, the calculations of the modified output ramp time for cells that are further down in the topological order are stopped.
