Abstract: An improved aeroprediction code (APC) allows aerodynamics to be predicted for Mach numbers up to 20 for configurations with flares. Moreover, the improved APC advantageously extends the static aerodynamic predictions for Mach numbers less than 1.2, improves the body alone pitch damping for Mach numbers above 2.0, and develops a new capability for pitch damping of flared configurations at Mach numbers up to 20. The improved APC also permits determination of aerodynamic effects associated with power-on events and trailing edge flaps. Corresponding methods are also described.

Abstract: A receiving device and method for operating a communication system are provided. The receiving device receives at least one Doppler channel estimate for at least one transmitter and a spatial covariance matrix of a corrupting environment. The Doppler channel estimates are used to create a Null Doppler spatial covariance matrix. A total Doppler spatial covariance matrix is created as a sum of the spatial covariance matrix of the corrupting environment, plus the Doppler spatial covariance matrix. A combining weight for at least one transmitter and at least one Doppler channel is created from the total Doppler spatial covariance and the at least one Doppler channel for the at least one transmitter.
Abstract: The present invention includes a method (500, 600, 700, 800), client device (900, 1000), server (1100, 1200) and article of manufacture (900, 1000, 1100, 1200) for compressing/decompressing a universal resource identifier URI. The method includes the steps of: determining, starting at a first end of a string, a first count of characters that sequentially match between a previous register and a current register; determining, starting at a second end of the string, a second count of characters that sequentially match between the previous register and the current register, and encoding the URI based on the first count and the second count.

Abstract: A converter continuously converts an input signal (110) to an output signal (112) even during correction and compensation. A primary converter (124) converts the signal along a forward primary path (104). A feedback converter (140) along a feedback path (106) outputs a feedback signal (116). A reference device (136) employs reference indicator (134) to provide a digital reference signal (135). A selection device (132) passes the digital reference signal (135) to an element (204) of the feedback converter (140) for outputting reference portion (208) of the feedback signal (116). The passing of the digital reference signal (135) to the element (204) is contemporaneous with the converting of the input signal (110) to the output signal (112). The evaluator (142) determines a conversion characteristic of the element (204) by employing a characteristic of the reference indicator (134).

Abstract: A microelectronic assembly (10) incorporating a particulate free underfill material (32 includes a substrate (24) having a plurality of bond pads (26) disposed on a substantially planar die attach region (24), and an integrated circuit die (12) having a die face (16) and a plurality of bond pads (20). The die face (16) is superimposed over the substrate die attach region (24) so that each of the die face bond pads (20) is generally aligned with a corresponding one of the substrate bond pads (26) and such that the die face is spaced apart from the die attach region by a gap not greater than about 20 microns. Each of the die face bond pads (20) is connected to its corresponding one of the substrate bond pads (26) by a solder connection (30). A particulate free polymeric material (32) is disposed in the gap, with the polymeric material substantially encapsulating each of the solder connections.

Abstract: A receiving device and method for operating a communication system are provided. The receiving device receives a plurality of time-domain Doppler channel estimates for at least one transmitter, a plurality of Doppler sinusoids, and a spatial covariance matrix of a corrupting environment. A Doppler spatial covariance matrix is created as a function of the time-domain Doppler channel estimates and the Doppler sinusoids. A total Doppler spatial covariance matrix is created as a function of the spatial covariance matrix of the corrupting environment and the Doppler spatial covariance matrix. A Doppler steering vector is created for at least one transmitter as a function of the Doppler channel estimates and the Doppler sinusoids. A combining weight for the at least one transmitter is then created as a function of the total Doppler spatial covariance matrix and the Doppler steering vector for at least one transmitter.

Abstract: The present invention includes a device, article of manufacture, method, memory and computer-readable memory for removal of coding errors introduced through a compression process. The device includes an error control logic unit (404) that is coupled to receive decompressed pixel information of a video decoder and is used for detecting coding errors and a filter (418) that is coupled to the error control logic unit (404) and is used for preparing decompressed pixel information for display.
Abstract: A communication device for simultaneously transmitting information on multiple sub-channels encodes information for each of the multiple sub-channels with a coding scheme to produce channel encoded information. A mask vector derived from a redundancy in the coding scheme, encodes the channel encoded information to transform the channel encoded information into codewords having pairwise Euclidean distance properties identical to those of the channel encoded information, Modulation of the sub-channels in accordance with the codewords in a modulator then produces a composite signal envelope having a peak-to-mean error power ratio (PMEPR) reduced relative to a PMEPR for correspondingly modulated channel encoded information.
Abstract: A level detector detects an input signal level. A rectifier (210) receives the input signal and provides a rectified signal. A prefilter (220) receives the rectified signal and attenuates high frequency components at frequencies near multiples of a decimation sample rate. The prefiltered signal is decimated (230) and low pass filtered by a lowpass filter (240) having a passband below the input frequency of the input signal. The level detector can be provided to control a variable gain stage circuit (935, 1010) which applies a gain to the input signal based on the level to form a dynamic range compressor or expander.

Abstract: A telescopic antenna assembly provides pairs of arms (210, 220, 230 and 240) on an elongated dielectric tube (260). A hot conductor (273) and a ground conductor (275) of a group of exciters couple energy between the arms and a feed line (250). The hot and ground conductors (273) and (275) slide within the tube (260) between extended and retracted positions while maintaining efficient electromagnetic coupling to the arms.
Abstract: A time-framed communications transceiver maintains synchronization through fade conditions by resetting a counter (640) whenever new synchronization parameters are stored in a memory (630) based on bursts detected by a receiver (610) and a burst synchronizer (620). A transmitter (690) transmits bursts based upon the synchronization parameters in the memory (630) when the time counter (640) has not exceeded a predetermined period of time. The receiver (610) re-establishes the synchronization parameters in the memory (630) when the time counter exceeds another, longer predetermined period of time before transmission by the transmitter (690).

Abstract: A half-wave balun network balanced for at least current is provided by a conductor section having contiguous conductor portions 130 and 140. A balanced port 110 is provided between ends of the conductor section. An unbalanced port 120 is provided between one end of the conductor section and a ground plane 107. A difference between impedances of the contiguous conductor portions 130 and 140 of the half-wave balun network provides for a selectable impedance ratio between the port impedances of the balanced and unbalanced ports 110 and 120. In one embodiment the number of different impedance conductor portions approaches infinity, thereby providing a tapered conductor section.
