Abstract: Described are techniques and mechanisms for enforcing trust between an application and a library loaded by the application. Very generally stated, the application declares one or more trusted code groups (“TCGs”) of which a library must be a member to be authorized for execution with the application. Libraries that are authorized to assert membership in one or more TCGs include a secure indicator of that membership. As the application executes and attempts to load a library, that libraries membership in a TCG authorized by the application is verified prior to loading the library.

Abstract: The disclosure is directed to techniques for region-of-interest (ROI) video processing based on low-complexity automatic ROI detection within video frames of video sequences. The low-complexity automatic ROI detection may be based on characteristics of video sensors within video communication devices. In other cases, the low-complexity automatic ROI detection may be based on motion information for a video frame and a different video frame of the video sequence. The disclosed techniques include a video processing technique capable of tuning and enhancing video sensor calibration, camera processing, ROI detection, and ROI video processing within a video communication device based on characteristics of a specific video sensor. The disclosed techniques also include a sensor-based ROI detection technique that uses video sensor statistics and camera processing side-information to improve ROI detection accuracy.

Abstract: A computer-implemented method of automatic rate realization for implementing a circuit design within a programmable integrated circuit can include comparing data rates of clock domains of the circuit design with frequencies of available clock sources of the circuit design and determining which clock domains have data rates that match frequencies of clock sources. For each clock domain that has a data rate matching a frequency of a clock source, loads of the clock domain can be clocked using a multiple synchronous clock technique with the matching clock source. For each clock domain having a data rate that does not match a frequency of a clock source, loads of the clock domain can be clocked using a clock enable technique. The circuit design specifying the clock circuitry for each clock domain can be output.
Abstract: A digital camera (10) has nine imaging setting items. A plurality of operation modes are assigned to each imaging setting item. An imaging operation is performed according to valid operation modes selected for each imaging setting item one by one. When a mode key (50) is operated, three valid mode characters out of nine valid mode characters respectively corresponding to nine valid operation modes are displayed on a monitor (30). When a jog dial key (48) is operated, a display of the valid mode characters is renewed. As to the imaging setting item at the reference position, invalid operation modes are detected, and invalid mode characters indicative of the detected invalid operation modes are additionally displayed on the monitor (30). When a set key (44) is operated in a state that a cursor is pointed to an arbitrary invalid mode character, an operation mode corresponding to the invalid mode character is validated.
Abstract: The invention provides method and apparatus for collaboration between a plurality of associated portlets in a portal server comprising: associating each portlet with a portlet descriptor describing context names; forming collaboration groups of portlets having corresponding context names for synchronized contents.

Abstract: A method of limiting the routing resources of an integrated circuit (IC) that are available for use when routing multi-fanout nets can include selecting a multi-fanout net comprising a source and a plurality of loads and identifying each region of the IC which does not include at least one of the plurality of loads. Each of the regions can have a defined geometry. A type of routing resource can be selected which has a physical orientation with respect to the IC that corresponds to the geometry of the regions of the IC. Each routing resource of the selected type that is located within a region of the IC which does not include at least one of the plurality of loads can be excluded from consideration when routing the multi-fanout net.
