摘要： An apparatus comprises a first driver circuit having a first output impedance while driving a plurality of couplers with a first current having a first phase to generate a wireless field. A second driver circuit drives the plurality of couplers with a second current having a second phase. A controller causes the second driver circuit to sequentially drive each of the plurality of couplers with the second current while causing the first driver circuit to simultaneously drive the other couplers with the first current. The controller identifies a subset of the plurality of couplers based on detecting a change from the first output impedance in response to each of the plurality of couplers being sequentially driven with the second current. The controller selectively energizes the subset of the plurality of couplers via one or both of the first and second driver circuits to wirelessly transfer the charging power.

摘要： Provided are techniques for low complexity video coding. For example, a video coder may be configured to calculate a first sum of absolute difference (SAD) value between a CU block and a corresponding block in a reference frame for the largest coding unit (LCU). The video coder may define conditions (e.g., background and/or homogeneous conditions) for the branching based at least in part on the first SAD value. The video coder may also determine the branching based on detecting the background or homogeneous condition, the branching including a first branch corresponding to both a first CU size of the CU block and a second CU size of a sub-block of the CU block. The video coder may then set the first branch to correspond to the first CU size, if the first CU size or the second CU size satisfies the background condition.

摘要： This invention describes a method and apparatus to cancel the mutual inductance between mutually coupled transmit coils, each of the transmit coils fed by individual power amplifiers, and the transmit coils all sharing a common ground with the power amplifiers. The methods and systems disclosed consist of coupling the return legs of each transmit coil to a mutual inductance cancellation circuit near a common ground return connection. The cancellation circuit uses a combination of inductors and capacitors to bridge various combinations of the transmit coils without physically connecting the "bridged" transmit coils. Transmit coils "bridged" using inductors have positive mutual inductance added to them, while transmit coils "bridged" using capacitors have negative mutual inductance added to them. Additionally, manipulation of the transmit coil overlap of overlapping transmit coils and/or manipulation of the location of the cancellation circuit can be used finely tune the mutual inductance between the transmit coils.

摘要： A transform module may be implemented in a video coder and may comprise a first transform stage, a transpose buffer, and a second transform stage. The first transform stage (e.g., a row transform processing module) may comprise a plurality of processing engines that may be similar in structure and may simultaneously operate on an NxN block of input values (e.g., pixel values or transform coefficients in a frequency domain) received from an input buffer. The transpose buffer may have a size that is smaller than the input block size. The transpose buffer may be implemented as a ping-pong buffer, thereby allowing the first transform stage to write to the transpose buffer during a time when a second transform stage is reading from the transpose buffer. The transpose buffer may transpose and transfer intermediate values received from the first transform stage to the second transform stage (e.g., column transform processing module).

摘要： As the quality and quantity of shared video content increases, video encoding standards and techniques are being developed and improved to reduce bandwidth consumption over telecommunication and other networks. One technique to reduce bandwidth consumption is intra-prediction, which exploits spatial redundancies within video frames. Each video frame may be segmented into blocks, and intra-prediction may be applied to the blocks. However, intra-prediction of some blocks may rely upon the completion (e.g., reconstruction) of other blocks, which can make parallel processing challenging. Provided are exemplary techniques for improving the efficiency and throughput associated with the intra-prediction of multiple blocks.
