  • Publication number: 20180256937
    Abstract: A pushup exercise apparatus comprised of a resistance band rectangle in shape large enough to cross the upper torso and encompass the both of the upper arms above the elbow is fed through the adjustable slides creating an adjustable loop around each arm for individual fitment of the athlete's size and dimension. Fitment across the upper torso and around the arms should be snug with little to no slack when the arms are shoulder width apart pointing away from the body.

  • Patent number: 8380468
    Abstract: A system, method, and software program for facilitating the assignment of cell specifications to a plurality of cells of a system design. The methods include generating a plurality of candidate cell specifications that meet the specification for the system design. In one embodiment, the method entails using information related to intra-range preference for cell specifications to generate a set of alternative system pareto-optimal solutions which define a boundary of a region of candidate cell specifications. In another embodiment, the method entails generating a substantially uniform set of candidate cell specifications using a prediction-based performance model, such as support vector regression model or cluster-weighted model, an optimizing algorithm such as conjugate-gradient or Markov Chain Monte Carlo Method, and a sample density model.

  • Patent number: 7356784
    Abstract: A method determining an IC (integrated circuit) design includes: determining one or more design variables, wherein the one or more design variables include one or more device variables and one or more weights; determining one or more net lengths and one or more layout metrics from the one or more device variables and the one or more weights; and determining the IC design from the one or more device variables and the one or more net lengths. The IC design includes a schematic and a layout. The process can be repeated as needed according to performance criteria that may include circuit performance metrics and layout performance metrics.
