Abstract: A method of mitigating a phase shift in a mutual capacitance touch screen panel having a plurality of row conductors intersecting with a plurality of column conductors to form a matrix of pixels, the method comprising: driving the row conductors with row drive signals formed from an excitation matrix, wherein each row in the excitation matrix is orthogonal to every other row in the excitation matrix, and the excitation matrix has a dimension larger than the matrix of pixels; sensing signals from the column conductors; and determining the mutual capacitance of the pixels using the sensed signals and an inverse of the excitation matrix. The excitation matrix can be a Hadamard matrix or a modified Hadamard matrix and can comprise a cyclic extension at the end of each row. A different region-specific phase shift can be applied to different clusters of signals.

Abstract: The invention is a transaction interface protocol wherein the interface protocol has a transaction identifier signal in each of the request and response channels. It is used between a target network interface unit (NIU) master and an initiator NIU slave that are directly connected through a transaction interface. The target NIU response channel uses the transaction ID signal to identify the entry in a context array associated with the corresponding request. The coupling of target NIU and initiator NIU enable the formation of an on-chip interconnect comprising multiple network-on-chip (NoCs) wherein the topology of the interconnect is simpler, smaller, faster, and has lower latency.

Abstract: A power disconnect unit within a data transport topology of a NoC includes an asynchronous clock domain adapter unit inserted between a master side manager unit and a slave side manager unit. This configuration allows for the master and slave side managers of the power disconnect unit to be placed physically far apart on the chip, relieving the need to route long power rail signals on the chip. A response data path and associated asynchronous clock domain adapter unit is optionally included on the chip. A path to bypass the asynchronous clock domain adapter units is optionally included on the chip to enable a fully synchronous mode of operation without the data latency cost of the asynchronous adapter unit.

Abstract: Embodiments are directed towards modifying a quality of an image without affecting a bit rate associated with a video sequence of images. For each macro-block (MB) or sub-block within a MB for a target image to be encoded, various statistics are determined for a luminance component and chrominance components that provide at least average values for the chrominance components that may then be used to identify saturation thresholds. The saturation thresholds are used to determine a Qlevel. An average Qlevel from at least a previous frame is used to generate a Q modulation factor that may be combined with an activity based modulation factor and/or variance based modulation factor, or used singly. The final quantizer is calculated by bit-rate controller base quantizer multiplied by the Q modulation factor, and may be used to encode a MB or sub-block within a MB.

Abstract: Apparatus and methods for efficient synaptic update in a network such as a spiking neural network. In one embodiment, the post-synaptic updates, in response to generation of a post-synaptic pulse by a post-synaptic unit, are delayed until a subsequent pre-synaptic pulse is received by the unit. Pre-synaptic updates are performed first following by the post-synaptic update, thus ensuring synaptic connection status is up-to-date. The delay update mechanism is used in conjunction with system “flush” events in order to ensure accurate network operation, and prevent loss of information under a variety of pre-synaptic and post-synaptic unit firing rates. A large network partition mechanism is used in one variant with network processing apparatus in order to enable processing of network signals in a limited functionality embedded hardware environment.

Abstract: A system, method, and computer program product for digital stabilization of video data from cameras producing multiple simultaneous views, typically from rolling shutter type sensors, and without requiring a motion sensor. A first embodiment performs an estimation of the global transformation on a single view and uses this transformation for correcting other views. A second embodiment selects a distance at which a maximal number of scene points is located and considers only the motion vectors from these image areas for the global transformation. The global transformation estimate is improved by averaging images from several views and reducing stabilization when image conditions may cause incorrect stabilization. Intentional motion is identified confidently in multiple views. Local object distortion may be corrected using depth information. A third embodiment analyzes the depth of the scene and uses the depth information to perform stabilization for each of multiple depth layers separately.

Abstract: Improved face tracking is provided during determination of an image by an imaging device using a low power face tracking unit. In one embodiment, image data associated with a frame and one or more face detection windows from a face detection unit may be received by the face tracking unit. The face detection windows are associated with the image data of the frame. A face list may be determined based on the face detection windows and one or more faces may be selected from the face list to generate an output face list. The output face list may then be provided to a processor of an imaging device for the detection of an image based on at least one of coordinate and scale values of the one or more faces on the output face list.
