Adaptive Filtering Neural Network Classifier

View page
US Patent:
57613834, Jun 2, 1998
Filed:
Jun 3, 1997
Appl. No.:
8/867719
Inventors:
Stephen J. Engel - E. Northport NY
Dennis Buckland - Bethpage NY
Assignee:
Northrop Grumman Corporation - Los Angeles CA
International Classification:
G06F 1518
US Classification:
395 21
Abstract:
An adaptive filtering neural network classifier for classifying input signals, includes a neural network and one or more adaptive filters for receiving input analog signals to be classified and generates inputs for the classifier. Each adaptive filter is characterized as having a predetermined number of operating parameters. An analog to digital converter converts each input signal into a digital signal before input to the neural network. The neural network processes each digital signal to generate therefrom a plurality of weighted output signals in accordance with the type of network implemented. One of the weighted output signals represents a class for the input signal, and an error signal representing a difference between the weighted output signals and a predetermined desired output is also generated by the network. A control device responsive to the error signal generates a further set of operating filter parameters for input to each of the adaptive filters to change the operating response thereof and minimize the error signal.

Adaptive Referencing Analog-To-Digital Converter

View page
US Patent:
49874179, Jan 22, 1991
Filed:
Feb 27, 1990
Appl. No.:
7/485627
Inventors:
Dennis J. Buckland - Bethpage NY
Assignee:
Grumman Aerospace Corporation - Bethpage NY
International Classification:
H03M 136
US Classification:
341159
Abstract:
To provide for a higher speed operation, lower cost and less complexity in terms of manufacturing, the present invention analog-to-digital converter has feedforwards, from the more significant comparators, to the less significant comparators. As the respective outputs of the comparators change state, the voltage representing that state, for that comparator, is fed to succeeding less significant comparators. With the exception of the most significant comparator whose reference bias voltage remains static, the respective bias voltages of the rest of the successive less significant comparators are shifted, either higher or lower, as the output states of their predecessor comparator(s) change. Consequently, the respective outputs of the comparators correspond, in a binary progressive manner, to a digital word that is representative of the voltage of an input analog signal.

Signal Processing For Ultra-Wideband Impulse Radar

View page
US Patent:
53811518, Jan 10, 1995
Filed:
Feb 2, 1994
Appl. No.:
8/190544
Inventors:
Sol Boles - Syosset NY
Dennis J. Buckland - Bethpage NY
Assignee:
Grumman Aerospace Corporation - Bethpage NY
International Classification:
G01S 728
US Classification:
342 21
Abstract:
An ultra-wideband impulse radar system for use on an airborne platform includes circuitry for coherently integrating the signals to improve signal-to-noise ratio so as to enhance the detection capability of the system, and for motion compensation of the signals to correct for inadvertent modulations of received signals due to buffeting or vibration of the airborne platform which may otherwise corrupt the filtering and signal integration processes. The inclusion of velocity filters and coherent integration despite the lack of phase information in the signals is accomplished by exploiting the time-delay properties of the received impulse signals, in which the observable pulse repetition frequency of the received signals differs from the transmitted pulse repetition frequency by virtue of the relative velocity between signal reflecting elements and the radar platform.

Simulator For Systems Having Analog And Digital Portions

View page
US Patent:
47929138, Dec 20, 1988
Filed:
Nov 3, 1986
Appl. No.:
6/926642
Inventors:
Dennis J. Buckland - Bethpage NY
Robert B. DeRobertis - Maspeth NY
Assignee:
Grumman Aerospace Corporation - Bethpage NY
International Classification:
G06J 100
US Classification:
364602
Abstract:
An apparatus for simulating, in an engineering workstation (EW) environment, the operation of circuits or systems having analog and digital portions. Information concerning the system or circuit is acquired with input devices such as a keyboard or mouse with the aid of a display and schematic capture programs. An analog simulator and a digital simulator are present in the EW. A first data extraction program extracts selected analog data from the analog simulator. A first conversion program converts the selected analog data into digital values. A first data insertion program provides the digital values as input (forcing functions) to the digital simulator. A second data extraction program extracts selected digital analysis data from the digital simulator. A second conversion program converts the selected digital data to analog data. A second data insertion program supplies the analog data as input to the analog simulator.
