摘要： Phase of an output signal is based on comparison of an oscillating signal with an adjustable threshold. Here, adjustment of the threshold results in a corresponding adjustment of the phase of the output signal. For example, the adjustable threshold may comprise an adjustable bias signal for a transistor circuit whereby the oscillating signal is provided as an input to the transistor circuit and the output of the transistor circuit provides the output signal. In some aspects these phase adjustment techniques may be employed to provide one or more tunable multiphase clocks.

摘要： Frequency and phase of an output signal is adjusted to track an input signal. A control signal is adjusted to control a frequency of an oscillating signal from which the output signal is derived. In some aspects the frequency of the oscillating signal is adjusted by reconfiguration of reactive circuits coupled to an oscillator circuit. Phase of the output signal may be adjusted based on comparison of the oscillating signal with an adjustable threshold. For example, the adjustable threshold may comprise an adjustable bias signal for a transistor circuit whereby the oscillating signal is provided as an input to the transistor circuit and the output of the transistor circuit provides the output signal.

摘要： Various operations may be performed based on a distance-related function associated with two or more devices. For example, an association procedure for two or more devices may be based on one or more determined distances. Similarly, presence management may be based on one or more determined distances. A distance-related function may take various form including, for example, a distance between devices, two or more distances between devices, a rate of change in a relative distance between devices, relative acceleration between devices, or some combination of two or more of the these distance-related functions.

摘要： A local feature descriptor for a point in an image is generated over multiple levels of an image scale space. The image is gradually smoothened to obtain a plurality of scale spaces. A point may be identified as the point of interest within a first scale space from the plurality of scale spaces. A plurality of image derivatives is obtained for each of the plurality of scale spaces. A plurality of orientation maps is obtained (from the plurality of image derivatives) for each scale space in the plurality of scale spaces. Each of the plurality of orientation maps is then smoothened (e.g., convolved) to obtain a corresponding plurality of smoothed orientation maps. Therefore, a local feature descriptor for the point may be generated by sparsely sampling a plurality of smoothed orientation maps corresponding to two or more scale spaces from the plurality of scale spaces.
摘要翻译：图像中的一个点的局部特征描述符是通过图像比例空间的多个级别生成的。图像逐渐平滑以获得多个刻度空间。点可以被识别为来自多个刻度空间的第一刻度空间内的兴趣点。为多个刻度空间中的每一个获得多个图像导数。对于多个刻度空间中的每个刻度空间，获得多个取向图（来自多个图像衍生）。然后对多个取向图中的每一个进行平滑（例如，卷积）以获得相应的多个平滑取向图。因此，可以通过从多个比例空间中稀疏采样对应于两个或更多比例空间的多个平滑取向图来生成该点的局部特征描述符。

摘要： A video compression system and method for compressing video data by reducing the temporal redundancy in the video data is described. A block of video data is divided into a variable number of blocks of pixel data of varying size. Each block of data is compared to a window of pixel data in a reference frame of pixel data by means of a motion vector calculator (82a-82d). A distortion figure is computed for each block of video data in distortion calculators (84a-84d). These distortion figures are then summed and weighted by means of distortion summing elements (86b-86d) and weighting factor multiplying elements (88a-c) respectively. The weighted summed distortion values are then compared against one another in comparators (90a-c), the results of which determine the way in which the block of video data is divided in motion vector selector elements (106, 108, 110). Only the residual difference, the displacement vectors and an indication of the block sizes used in the prediction are needed for transmission or storage.
