  • Patent number: 8891869
    Abstract: A system and method for effectively performing an integrated segmentation procedure comprises an image segmenter that includes a texture modeler, a contrast modeler, and a model integrator. The texture modeler creates a texture model based upon an original image. Similarly, the contrast modeler creates a contrast model based upon the original image. The model integrator then performs a model integration procedure to create a final segmented image by integrating the texture model and the contrast model according to a calculated texture model metric. A processor of an electronic device typically controls the image segmenter to perform the integrated segmentation procedure.

  • Publication number: 20140333524
    Abstract: Systems, methods and computer storage mediums securely authenticate an identity of an individual based on a pattern that is traced by the individual. Embodiments of the present disclosure relate to prompting an individual with a pattern to trace when attempting to authenticate the identity of the individual during an identity authentication session. Motion-based behavior data that is generated by motions executed by the individual as the individual traces the pattern is captured via a motion-capturing sensor. The motion-based behavior data is unique to the individual and has a low likelihood of being duplicated by an unauthorized individual attempting to fraudulently pose as the individual. The captured motion-based behavior data is compared to previously captured motion-based behavior data from previous traces of the pattern completed by the individual.

  • Patent number: 8873606
    Abstract: Methods, systems, and apparatuses are described for reducing the latency in a transceiver. A transceiver includes a high latency communication channel and a low latency communication channel that is configured to be a bypass channel for the high latency communication channel. The low latency communication channel may be utilized when implementing the transceiver is used in low latency applications. By bypassing the high latency communication channel, the high latency that is introduced therein (due to the many stages of de-serialization used to reduce the data rate for digital processing) can be avoided. An increase in data rate is realized when the low latency communication channel is used to pass data. A delay-locked loop (DLL) may be used to phase align the transmitter clock of the transceiver with the receiver clock of the transceiver to compensate for a limited tolerance of phase offset between these clocks.

  • Patent number: 8873833
    Abstract: A system for performing a scene representation procedure includes an image manager that processes source images from a given scene to define subscenes in the source images. The image manager creates an image understanding graph for each of the source images, and also creates a scene representation graph for each of the source images based upon the corresponding subscenes and certain image characteristics. The image manager further generates an integrated scene representation to represent all of the source images with a single representation. A processor of an electronic device controls the image manager to perform the scene representation procedure.

  • Patent number: 8852784
    Abstract: Methods and apparatus supporting an electrical connection are disclosed. Systems previously equipped with wire interfaces, such as battery terminals, can be equipped with a connector assembly to significantly reduce a hazard of electrical shock to a user. The connector assembly includes a stress relief component that attenuates a force, applied to the stress relief component, to reduce its effect on the connector assembly. By attenuating the force, the connector assembly maintains a substantially fixed position relative to the battery pack component and mitigates a potential for disruption in electrical connectivity. Techniques disclosed herein benefit users of battery packs or other devices as well as manufacturers by increasing safety, reliability, and ergonomics.

  • Patent number: 8842735
    Abstract: Phase correlation is an established method for computing motion which relies on the ability to find peaks in a computed phase correlation surface. Two methods to improve the ability to detect peaks in the phase correlation surface are described herein. The first method applies a theoretically-derived and spatially-varying gain to the phase correlation surface. The gain compensates for peaks whose amplitudes have been decreased due to windowing effects; such effects are unavoidable in phase correlation. The second method uses concepts from matched filters to improve detection of peaks whose amplitudes are diminished due to a spreading of the peak energy into surrounding positions in the phase correlation surface. Peak detection filters allow such low-amplitude peaks to be properly detected. It is possible to use only the first method, or only the second method or both methods combined.
