10/421409
Inventors:
William T. Yost - Newport News VA, US
K. Elliott Cramer - Newport News VA, US
Daniel F. Perey - Yorktown VA, US
Assignee:
The United States of America as represented by the Administrator of the National Aeronautics and Space Administration - Washington DC
International Classification:
G08B 1710
US Classification:
340632, 340605, 174 25 C, 174 25 R, 174110 R, 73 3103
Abstract:
Passive and active methods for anticipating problems with electrical wiring are provided. An insulative material in contact with an electrical conductor has at least one impurity that is impregnated in the insulative material and/or disposed thereon. An environment around the electrical conductor is monitored for the presence or the level of the impurity(ies) emanating from the insulative material in the form of a gaseous effluent. An alarm signal is generated when a predetermined level of the gaseous effluent is detected.

View page
US Patent:
7181942, Feb 27, 2007
Filed:
Sep 9, 2004
Appl. No.:
10/943649
Inventors:
William T. Yost - Newport News VA, US
K. Elliott Cramer - Yorktown VA, US
Daniel F. Perey - Yorktown VA, US
Assignee:
The United States of America as represented by the Administrator of the National Aeronautics and Space Administration - Washington DC
International Classification:
B21D 39/00
US Classification:
72 172, 72 162, 72 164, 72 173, 72 3101, 29705, 29720, 73587, 73588
Abstract:
An ultrasonic device and method obtains desirable crimp connections between a crimp connector and a wire, or bundle of wires, by assessing the desirability of connections made in a wire-to-wire connection and in other situations where two materials with good acoustic propagation characteristics are joined together via deformation. An embodiment of the device as a crimping tool comprises a compressing means, pulse-generating circuitry, at least one ultrasonic transmitting transducer, at least one ultrasonic receiving transducer, receiving circuitry, and a display. The user may return to a previously crimped connection and assess the desirability of the connection by compressing the device about the connection, sending an acoustic signal through the crimp, and comparing the received signal to a signal obtained from known desirable connections.

Assessment And Calibration Of A Crimp Tool Equipped With Ultrasonic Analysis Features

View page
US Patent:
8490463, Jul 23, 2013
Filed:
Sep 14, 2010
Appl. No.:
12/881431
Inventors:
William T. Yost - Newport News VA, US
Daniel F. Perey - Yorktown VA, US
K. Elliott Cramer - Yorktown VA, US
Assignee:
The United States of America as represented by the Administrator of the National Aeronautics and Space Administration - Washington DC
International Classification:
G01N 29/04
US Classification:
73 182, 73600, 73602, 73609, 73610
Abstract:
A method is provided for calibrating ultrasonic signals passed through a crimp formed with respect to a deformable body via an ultrasonically-equipped crimp tool (UECT). The UECT verifies a crimp quality using the ultrasonic signals. The method includes forming the crimp, transmitting a first signal, e. g. , a pulse, to a first transducer of the UECT, and converting the first signal, using the first transducer, into a second signal which defines an ultrasonic pulse. This pulse is transmitted through the UECT into the crimp. A second transducer converts the second signal into a third signal, which may be further conditioned, and the ultrasonic signals are calibrated using the third signal or its conditioned variant. An apparatus for calibrating the ultrasonic signals includes a pulse module (PM) electrically connected to the first and second transducers, and an oscilloscope or display electrically connected to the PM for analyzing an electrical output signal therefrom.

Process And Apparatus For Nondestructive Evaluation Of The Quality Of A Crimped Wire Connector

View page
US Patent:
20120192407, Aug 2, 2012
Filed:
Feb 1, 2012
Appl. No.:
13/363413
Inventors:
William T. Yost - Newport News VA, US
Karl E. Cramer - Yorktown VA, US
Daniel F. Perey - Yorktown VA, US
Keith A. Williams - Wesr Lafayette IN, US
Assignee:
U.S.A. as represented by the Administrator of the National Aeronautics and Space Administration - Washington DC
International Classification:
H01R 43/048
G01R 19/25
G01R 19/00
G01H 1/00
US Classification:
29593, 29705
Abstract:
A process and apparatus for collecting data for nondestructive evaluation of the quality of a crimped wire connector are provided. The process involves providing a crimping tool having an anvil and opposing jaw for crimping a terminal onto a stranded wire, moving the jaw relative to the anvil to close the distance between the jaw and the anvil and thereby compress the terminal against the wire, while transmitting ultrasonic waves that are propagated through the terminal-wire combination and received at a receiving ultrasonic transducer as the jaw is moved relative to the anvil, and detecting and recording the position of the jaw relative to the anvil as a function of time and detecting and recording the amplitude of the ultrasonic wave that is received at the receiving ultrasonic transducer as a function of time as the jaw is moved relative to the anvil.

Compact Active Vibration Control System For A Flexible Panel

View page
US Patent:
20130113338, May 9, 2013
Filed:
Nov 8, 2011
Appl. No.:
13/291372
Inventors:
Noah H. Schiller - Yorktown VA, US
Randolph H. Cabell - Hampton VA, US
Daniel F. Perey - Yorktown VA, US
Assignee:
U. S.A. as represented by the Administrator of the National Aeronautics and Space Administration - Washington DC
International Classification:
B06B 1/06
US Classification:
310322
Abstract:
A diamond-shaped actuator for a flexible panel has an inter-digitated electrode (IDE) and a piezoelectric wafer portion positioned therebetween. The IDE and/or the wafer portion are diamond-shaped. Point sensors are positioned with respect to the actuator and measure vibration. The actuator generates and transmits a cancelling force to the panel in response to an output signal from a controller, which is calculated using a signal describing the vibration. A method for controlling vibration in a flexible panel includes connecting a diamond-shaped actuator to the flexible panel, and then connecting a point sensor to each actuator. Vibration is measured via the point sensor. The controller calculates a proportional output voltage signal from the measured vibration, and transmits the output signal to the actuator to substantially cancel the vibration in proximity to each actuator.

Karl Elliott Cramer - Yorktown VA, US
Daniel F. Perey - Yorktown VA, US
Assignee:
U.S.A. as represented by the Administrator of the National Aeronautics and Space Administration - Washington DC
International Classification:
G01N 29/07
US Classification:

Abstract:
A method and apparatus for evaluating and/or quantifying damage to wire strands of a wire caused during installation of a crimped wire connector, involves launching an ultrasonic wave having known characteristics into a wire at a location that is either the crimp or is adjacent the crimped wire connector, and detecting changes in the characteristics (e.g., amplitude and/or phase shift) of the wave as it is propagates along a length of the wire.
