Patent number: 6721682Abstract: 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.Type: GrantFiled: January 7, 2002Date of Patent: April 13, 2004Assignee: The United States of America as represented by the Secretary of the NavyInventors: Frankie G. Moore, Thomas C. Hymer

Patent number: 6504506Abstract: 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.Type: GrantFiled: June 30, 2000Date of Patent: January 7, 2003Assignee: Motorola, Inc.Inventors: Timothy A.

Patent number: 6411232Abstract: 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).Type: GrantFiled: September 30, 1999Date of Patent: June 25, 2002Assignee: Motorola, Inc.Inventors: Matthew R.

Patent number: 6307892Abstract: 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.Type: GrantFiled: January 30, 1998Date of Patent: October 23, 2001Assignee: Motorola, Inc.Inventors: Alan Jones, Timothy Alan Wilkinson

Patent number: 6023191Abstract: 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.Type: GrantFiled: August 29, 1997Date of Patent: February 8, 2000Inventors: Lawrence Edwin Connell, Mark Joseph Callicotte, William Joseph Roeckner

Patent number: 5930268Abstract: 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).Type: GrantFiled: December 20, 1996Date of Patent: July 27, 1999Assignee: Motorola, Inc.Inventors: Christopher Neil Kurby, John William Arens, Kathleen Helen Ryan

Patent number: 5861853Abstract: 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.
