摘要： A thin client device for use in a home network includes a network port by which the device connects to the home network and a data/memory port by which a data interface such as a memory card or communications port may be connected to the device. The device is configured such that data from the data interface is transferred to a server that is coupled to the home network. The transfer may be automatic or it may be controlled by a user. Where the thin client device includes signal processing hardware, the data from the data interface may be processed by the signal processing hardware and presented to the user.

摘要： A process to synchronize information transmitted from an information provider to a plurality of network elements is provided. The process determines a temporal difference between related network elements and compensates for this difference by dilating an information signal provided to at least one of the network elements to resynchronize the data presented to the network elements. The process is repeated periodically in order to maintain a desired synchronization level.

摘要： An arrangement comprising a master unit and one or more slave units, where the master sends out bursts, at specified intervals, in a frequency hopping manner, with each burst being at a different frequency. The slave responds with acknowledgements, and the signal strengths of the acknowledgments are used to select one or more of the acknowledgments as the signals used for distance, or range, estimation. Advantageously, the durations of the intervals are fairly long during normal operation, and short at times when certain conditions occur, such as loss of communication or when accurate range estimation is required. Also, the slave is adapted to sleep while it is not expecting a burst transmission from the master, thereby saving power. The frequency hopping sequencing is preferably pseudo random, with a different sequencing of the same set of frequencies at different modes of operation.

摘要： The DC offset error of a quadrature modulated RF signal is corrected by introducing a specific trial offset correction value, D, into the DC offset correction circuits 3, 4 or 5 times, by measuring the carrier power resulting from each trial introduction, and by using the information to determine the DC offset correction components, Icor and Qcor. According to an ideal case first embodiment, specific offset D is employed in three different measurement combinations to determine the correction factors Icor and Qcor. According to an alternative embodiment, a fourth offset correction measurement, needed to estimate a single offset control scale factor, is used to account for an unknown power scale factor A. According to a second alternative embodiment, five offset correction measurements are used to account for separate offset control scale factors for the I and Q channels.

摘要： A multilayered printed wiring board (PWB) with improved probing for in-circuit, functional, and prototype testing. The PWB includes a support layer and at least a top layer disposed over the support layer. The top layer has one or more circuits with traces for measuring signals produced by the circuit. A test-layer for routing the signals to the edge of the board is provided between the top layer and the support layer. The test-layer includes long traces extending from a first location substantially beneath the traces to a second location adjacent to the edge of the board. Contacts for measuring the signals produced by the circuit are provided on the top layer adjacent to the edge of the board. A first set of vias may be used to connect the first ends of the long traces to the traces on the top layer and a second set of vias may be used to connect the second ends of the long traces to the contacts. Buried resistors embedded in the test-layer may be provided for connecting the first set of vias with the long traces to create resistive coupling and low-level feedback for probing of the circuit at the contacts.

摘要： Human inspection of an object (12) having a light-reflective areas (20) thereon arrayed in individual arrays (21) is enhanced by first capturing the image of selected portions of the arrays via one or more image capture devices (34). The images are processed to create a single image frame in which like portions of like arrays of light-reflective are uniformly spaced and oriented in a two-dimensional array having large scale regularity. The single image frame is then displayed on a display (48) for observation by a human operator (29). Because the displayed image frame of the light-reflective areas has large scale regularity, the operator bility to detect defects associated with missing or misaligned light-reflective areas will be enhanced.

摘要： To obtain an enhanced two-dimensional image of a raised, light-reflective reflective feature (12), and its lower height surrounding background such that the contrast between them is enhanced, a line of light having a gradient profile is directed at an acute angle at the feature and its background to illuminate a strip of area thereacross. The reflectance intensity of the illuminated strip will vary in accordance with the height thereof because of the gradient intensity profile of the line of light. When the line of light is spanned across the feature and its background, the resultant image of the feature and its background, captured by spanning a linescan camera (24) thereacross, will exhibit an enhanced contrast between the feature and its background because of the greater height of the feature.
