Power Supply Booster
US Patent:
6417580, Jul 9, 2002
Filed:
Oct 25, 1999
Appl. No.:
09/426201
Inventors:
Timothy J. Williams - Charlottesville VA
Matthew B. Pereira - Barboursville VA
Matthew B. Pereira - Barboursville VA
Assignee:
General Electric Company - Schenectady NY
International Classification:
H02J 100
US Classification:
307 70, 307 80, 307 69, 307 18
Abstract:
A power supply booster module for a programmable logic controller system replaces the primary power supply for a number of modules within the system. The power supply booster module allows high power consuming or highly complex modules to be used within a programmable logic controller system. The power supply booster module eliminates the problems present in prior programmable logic controller systems where the primary power supply could not output enough current to adequately power all of the system modules or modules that have a high power requirement.
System And Method For Detecting An Operational Fault Condition In A Power Supply
US Patent:
7091739, Aug 15, 2006
Filed:
Jun 25, 2004
Appl. No.:
10/710204
Inventors:
Timothy James Williams - Charlottesville VA, US
Assignee:
General Electric Company - Schenectady NY
International Classification:
G01R 31/36
US Classification:
324771, 323285
Abstract:
A system and a method for detecting an operational fault condition in a power supply are provided. The power supply has a controller operably coupled to first and second switches. The first and second switches are connected in series between a voltage source and a ground node, wherein a first electrical node is electrically coupled between the first and second switches. The first electrical node is further coupled to a first end of an inductor. The controller is configured to induce the first and second switches to apply voltage pulses to the first electrical node. The method includes monitoring a voltage at the first electrical node to determine a number of voltage pulses being applied to the first electrical node over a predetermined time interval. The method further includes determining when a first operational fault condition has occurred when the number of voltage pulses being applied to the first electrical node over the predetermined time interval is less than or equal to a predetermined number of voltage pulses.
Apparatus And Method For Detecting A Carrier Signal
US Patent:
5012492, Apr 30, 1991
Filed:
Sep 29, 1989
Appl. No.:
7/415691
Inventors:
Daniel W. Sexton - Charlottesville VA
Timothy J. Williams - Charlottesville VA
Timothy J. Williams - Charlottesville VA
Assignee:
GE Fanuc Automation North America, Inc. - Charlottesville VA
International Classification:
H03D 304
US Classification:
375 82
Abstract:
A carrier detection circuit is provided for reliably detecting the presence of a carrier signal. The carrier detection circuit operates on a carrier signal which includes a first symbol exhibiting a first frequency representing a logic 1 and a second symbol exhibiting a second frequency representing a logic 0. A first carrier detect pulse exhibiting a first logic state is generated each time the carrier signal exceeds a predetermined threshold voltage. A plurality of consecutive first carrier detect pulses are checked to determine the logic state of each. A second carrier detect pulse is generated if it is determined that each of the plurality of consecutive first carrier detect pulses exhibit the first logic state.
