  • Patent number: 11122420
    Abstract: Embodiments for intelligent temporary contact sharing between user equipment (UE) by a processor. A temporary exchange of contact data may be provided between a first UE and a second UE via a wireless communication network according to one or more policies, user preferences, historical data, a defined physical or virtual proximity between the first UE and the second UE, or a combination thereof. The contact data may be automatically deleted between the first UE and the second UE according to the one or more policies, the user preferences, the historical data, the defined physical or virtual proximity between the first UE and the second UE, or a combination thereof.
    Type: Grant
    Filed: May 4, 2018
    Date of Patent: September 14, 2021
    Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION

  • Patent number: 6298467
    Abstract: A method for reducing a hysteresis effect in silicon-on-insulator CMOS circuits includes the steps of providing a circuit having CMOS objects, defining a beta ratio; resizing the CMOS objects based on the beta ratio, determining if the objects are a minimum size based on predetermined size criteria, if the objects are larger than the minimum size, defining a scaling factor based on a performance level of the object and resizing the object based on the scaling factor such that delay variations of the resized circuit are substantially constant. Also, a computer program product is provided for reducing the hysteresis effect.
