摘要： An input random access memory (RAM) module of a fast Fourier transform (FFT) engine of a DVB receiver is used to store, during a first time period, delayed versions of an input signal that includes a first orthogonal frequency division multiplexed (OFDM) symbol and a cyclic prefix therefor received at the receiver, and samples for a second OFDM symbol to be demodulated using the FFT engine during a second time period. Delayed versions of the input signal are stored in the input RAM module of the FFT engine in a first-in-first-out (FIFO) fashion for signal acquisition and for FFT processing. Similarly, an output RAM module of the FFT engine is used to store moving averages of an autocorrelation of the input signal with its cyclic prefix computed over presumed guard intervals and over multiple symbols.

摘要： A guiding device guides, in a main body of a liquid ejection apparatus, a flexible passage forming member having a passage therein in a predetermined routing direction while curving the passage forming member. The guiding device includes a holding member. The holding member is engaged with a curved section of the passage forming member, and holds the curved section in an undeformable manner in the apparatus main body. The holding member guides the passage forming member in the routing direction. Thus, the guiding device is capable of efficiently routing passage forming members while bending the members in a body of a liquid ejection apparatus.

摘要： A liquid retainer support is arranged in a body of a liquid ejection apparatus in an immovable manner or in such a manner as to allow reciprocation of the liquid retainer support. A liquid retainer is secured to the liquid retainer support. A liquid retainer chamber is defined in the liquid retainer in such a manner as to allow communication between the liquid retainer chamber and the atmospheric air. A liquid supply system of the liquid ejection apparatus is manufactured by blocking the liquid retainer chamber from the atmospheric air and connecting a liquid passage defining body to the liquid retainer for supplying liquid from a liquid reservoir to the liquid retainer chamber. The liquid passage defining body includes a liquid passage that communicates with the liquid reservoir. In this manner, the cost for manufacturing the liquid supply system is reduced.

摘要： An ink supplying and collecting apparatus includes a case, ink cartridges detachably attached to the case, and a collecting container detachably attached to the case. The ink cartridges supply ink to a recording head of a printer via ink supply tubes. The collecting container collects ink drained from the recording head via an ink drain tube. The case is located outside of and is separate from the printer. Thus, the sizes and shapes of the ink cartridges and the collecting container can be freely designed.

摘要： A terrestrial C/A code GPS receiver system digitally samples, filters and stores a segment of 11 half chips of the received composite as a binary number and multiplexes this number for parallel correlation with each of a series of multibit code replicas for the satellites to be tracked. Each of the time delay specific correlation products are accumulated in a cell of a memory matrix so that at least twenty two delays for each satellite may be evaluated each code period providing fast reacquisition, even within a city intersection, as well as correction of multipath tracking and multipath interference. All cells of the memory matrix may be used for a acquisition of a single satellite in about 4 ms. Two satellite tracking, in addition to altitude hold, uses cross track hold alternating with clock hold to update the cross track estimate. Single satellite tracking uses cross track and clock hold together. Navigation data is updated with detected changes in motion including turns.

摘要： A method for generating technology data files for use by at least one chip and circuit analysis tools begins by accepting a user analysis request for a specific chip and circuit analyses. The design automation tool required for the requested analysis is then selected. A standard, generic technology data file(TDF) is converted to a custom TDF specified for a given design analysis tool from a set of TDF formatting rules for the given design analysis tool. The chip coordinate references, process parameters and line segment layout data to be tested are extracted from a physical design data layout file. The line segment layout data of a standard wafer test site for the foundry/process selected is extracted from a circuit simulation model of the desired foundry/process. The design automation tool is executed using the foundry/process and line segment layout data as requested in the user analysis request. An analysis specified by said user analysis request with the selected design automation tool is executed using the foundry/process and line segment layout data of the standard wafer test site. The results of the analysis using the foundry/process and line segment layout data of the standard wafer test site are compared with the actual data describing the test site function. Reports are issued describing the success of the analysis.

摘要： This invention provides a method of preparing an electrical overstress material having a nonlinear resistance which declines sharply in response to an electric field exceeding a clamping voltage so as to be able to shunt out transient surges which method comprises using an adhesive binder, for example a silicone rubber or a ceramics dispersion, and thorough mixing therein of small conductive, and optionally semiconductive particles, for example nickel particles of various morphologies and silicon carbide particles respectively, followed by molding under pressure and curing. The invention is also directed to the electrical overstress material itself which has excellent strength and integrity as well as survivability from multiple surges and has multiple applications in, for example, electrical outlet strips and power cables. The invention is also directed to a power outlet strip comprising a plurality of surge arresting elements composed of the electrical overstress material of the invention.
