摘要： Techniques for increasing the battery life on a mobile device by decreasing the energy consumption of the mobile device's wireless fidelity (Wi-Fi) interface are described. In one embodiment, the mobile device's Wi-Fi interface is automatically disabled when the device is not engaged in a voice over internet protocol (VoIP) call via the Wi-Fi interface. When a VoIP call is initiated on the device, or when the device receives a wake up call from a server via its Cellular interface, the Wi-Fi interface is automatically enabled. Using its Wi-Fi interface, the mobile device then connects to an IP-based network via a Wi-Fi access point. The server then initiates a direct call, wherein VoIP technology is used by the mobile device, between the mobile device and a VoIP calling device.

摘要： A method of, apparatus for, and computer-readable medium for rapid, real time kinematics determination requiring lowered information transmission for position updates than traditional RTK systems. Position signals are received from a base station and roving system and a compressed position signal is received from the base station. A position estimate using an integrated method is determined using the received position signals from the base station and the roving system and the compressed position signal from the base station. Ambiguity resolution of the position estimate is enhanced by applying a quality control procedure using derived validation criteria. A second position estimate is derived based on the enhanced ambiguity resolution. Because of the use of the compressed position signal smaller transmissions may be performed at a more rapid rate providing a higher position update rate.

摘要： An aerofoil blade damper comprising an elongate member which is inserted within a core passage of the blade and extends within the blade with the damper retained therein at one end which is closest to the blade root with the remainder of the damper free to move relative to and within the passage; such movement generating friction which dissipates any vibration. The damper comprises a plate insert including at least two discrete substantially oppositely directed contact regions which are arranged, in use, to frictionally engage the passage. The discrete contact regions may be provided by protrusions in the form of contact pads or arms extending from the plate or be provided by the corrugations of the plate. A contact load on the contact regions is provided by the resilience of the damper, an interference fit of the damper and/or centrifugal loading of the damper and contact regions during operation.

摘要： A pixel-data processing circuit delivers a fixed number of pixels to a video processing stage using an irregular sampling pattern that is defined by a variably-definable sampling window. In one example embodiment directed to processing an input stream of pixels corresponding to an array of video pixels, the window size is selected from one of various options for sampling subsets of the array as a two-dimensional window that spans the pixels in the array. A sampling-window is used such that the window size is a multiple of the sampling-window size and the sampling-window size defines the fixed number of pixels. The processing includes concurrently moving pixel data from the input stream into a first set of line buffers with the pixels stored in the first set of line buffers including pixels for the established window size, prefetching the stored pixels from the first set of line buffers into a second set of line buffers, the second set of line buffers being sufficiently long to store at least the pixels corresponding to the established sampling-window size, and fetching the fixed number of pixels from the second set of line buffers. In various applications, in addition to flexibility, the present invention realizes enhanced throughput.
摘要翻译：像素数据处理电路使用由可变定义的采样窗口定义的不规则采样模式将固定数量的像素传送到视频处理级。在针对处理对应于视频像素阵列的像素的输入流的一个示例性实施例中，窗口大小从用于将阵列的子集进行抽样的各种选项中的一个选择为跨越阵列中的像素的二维窗口。使用采样窗口，使得窗口大小是采样窗口大小的倍数，采样窗口大小定义固定数量的像素。该处理包括将来自输入流的像素数据同时移动到第一组行缓冲器中，其中存储在第一组行缓冲器中的像素包括用于建立的窗口大小的像素，将存储的像素从第一组行缓冲器预取为第二组线缓冲器，第二组线缓冲器足够长以至少存储与所建立的采样窗口大小相对应的像素，以及从第二组线缓冲器获取固定数量的像素。在各种应用中，除了灵活性之外，本发明实现了增加的吞吐量。

摘要： A damping member (27) for positioning between the undersides of the platforms of adjacent turbine blades (20) and the peripheral surface of a disc (19) upon which the turbine blades (20) are mounted. The damping member (27) comprises first, second and third portions (28,31 and 32). The first portion (28) simultaneously engages the adjacent blade platforms (24) whereas the second and third portions (31,32) converge to engage each other at the disc (19) peripheral surface from a spaced apart relationship with each other at their attachment to the first portion (28). Frictional interaction between the second and third portions (31,32) and the disc (19) peripheral surface provides damping of turbine blade (20) vibration.
