  • Publication number: 20230175539
    Abstract: A clip system is provided for wearable devices. In use, a clip mechanism of a wearable device includes a first arm configured to attach to a housing of the wearable device via a first hinge. Additionally, the clip mechanism includes a second arm configured to attach to the housing of the wearable device via a second hinge. Additionally, the clip mechanism includes a coupler to connect the first arm and the second arm, where the coupler comprises an elastic member which is configured to cause the coupler to change a distance from a side of the housing.

  • Patent number: 8621413
    Abstract: A system, method and computer program product are provided for reducing a deactivation function utilizing an optimal reduction. In use, a deactivation function is identified. Additionally, reductions for the deactivation function are calculated. Further, an optimal reduction of the calculated reductions is determined. Moreover, the deactivation function is reduced, utilizing the optimal reduction.

  • Publication number: 20100164731
    Abstract: A method and apparatus are provided for evaluating viewing behaviors of media viewers. The viewing space of the media is imaged and analyzed to detect media viewers and evaluate their viewing behaviors using machine vision. Based on their evaluated viewing behaviors, a health care feature may be delivered to the media viewers.

  • Patent number: 7539956
    Abstract: A system, method and computer program product are provided for simultaneous cell identification/technology mapping. In use, a plurality of data operators is received. Further, at least two cells are identified for each data operator, simultaneously with technology mapping. By this design, at least one of the cells may thus be selected for design optimization purposes.

  • Patent number: 6526551
    Abstract: Formal verification of a logic design through implicit enumeration of strongly connected components. The invention provides for efficient, cost-effective formal verification of logical circuits and systems using a method that is much less computationally expensive than other known methods. A digraph is recursively decomposed using reachability analysis. Non-trivial, strongly connected components derived through the use of the invention can be compared to expected behavior of a circuit or system. Alternatively, the invention can be applied to detect so-called “bad cycles” which are encountered in many formal verification problems.
