Abstract: A system is disclosed, which may include a clock distribution circuit. The clock distribution circuit may include a duty cycle controller to distribute a clock output signal to a plurality of remote locations on a clock grid. The duty cycle controller may adjust, in response to a duty cycle control signal, a duty cycle of the clock output signal. The clock distribution circuit may also include a duty cycle measurement unit, to measure the duty cycle of the clock output signal at one of the remote locations, generate the duty cycle control signal, and generate and write duty cycle data values to a memory unit. The system may also include control logic to calculate and transmit a clock distribution circuit end-of-life date, by applying a model to stored duty cycle data values and to a duty cycle controller adjustment state.

Abstract: A smart card architecture includes a run-time environment, a card manager, one or more security domains, a provider application and an issuer application. One or more APIs provide communication. The life cycle of the card and card manager includes states: Pre-production, Ready, Initialized, Secured, Locked and Terminated. The life cycle of an application includes states: Installed, Selectable, Personalized, Blocked, Locked and Deleted. A card registry keeps track of card manager and application data elements. The functionality of a security domain on a smart card is extended to allow it to perform delegated management of smart card applications: delegated loading, installation and/or deletion of an application. A provider of an application is assured of more direct control and management of their application, yet an issuer still maintains some control over the management of the card.

Abstract: A method and apparatus for determining a position of a member contacting a touch screen includes determining initial coordinates of the member at a first time, determining subsequent coordinates of the member at a subsequent time, and defining possible coordinates of the member to be between the initial coordinates and subsequent coordinates, then redetermining subsequent coordinates of the member at a further subsequent time, and redefining possible coordinates of the member to be between redetermined subsequent coordinates and previously defined possible coordinates. Redetermining subsequent coordinates and redefining possible coordinates may be repeated until subsequent coordinates and redefined coordinates are within a predetermined distance for a predetermined number of repetitions. The method and apparatus may be reinitialized if subsequent coordinates are beyond a specified distance of previously determined possible coordinates.
