Publication number: 20100207728Abstract: An energy management system includes a module for an energy consuming device. The module has a module main controller including a computer processor in communication with a module computer readable storage medium containing computer executable code. When the computer executable code is executed by the computer processor, it performs a method including determining whether a demand state is a peak demand state, employing a reduced operational mode of the energy consuming device during a peak demand state, and employing a normal operational mode of the energy consuming device during a demand state other than a peak demand state. In an embodiment, the system also includes a system main controller in communication with the module.Type: ApplicationFiled: February 18, 2009Publication date: August 19, 2010Applicant: General Electric CorporationInventors: George William Roscoe, John Keith Besore, Darko Ilickovic, Thomas Frederick Papallo, Jr., Cecil Rivers, Jr., Brian Michael Schork

Patent number: 6771170Abstract: A circuit monitoring system for performing synchronized waveform capture. A waveform capture trigger communication network interconnects a plurality of monitoring devices. The system provides direct device to device trigger communication between monitoring devices in a synchronized group. Power system waveform data is stored in the monitoring device memory of all members of the synchronized group in response to a trigger event initiated by any monitoring device in the synchronized group. High speed trigger communication results in substantially simultaneous waveform capture among the members of the synchronized group.Type: GrantFiled: April 10, 2001Date of Patent: August 3, 2004Assignee: General Electric CompanyInventors: Thomas Frederick Papallo, Jr., Mark Fredrick Culler, David Fletcher, Gregory Lavoie, John James Dougherty, Michael S.

Patent number: 6495781Abstract: An indicator on a stored energy motor operator indicates that the circuit breaker is “on” when the contacts are closed and the handle is in an on position and when the contacts are open and the handle is in an on position. The indicator only indicates that the circuit breaker is “off” when the contacts are open and the handle is in an off position. To achieve these conditions, the stored energy motor operator includes a flag bearing on and off indicia, the flag attached to one end of a connecting bar, the other end of the connecting bar pivotally connected within the stored energy motor operator. A lever is attached to a central portion of the connecting bar at a spring, the lever including a hook portion for hooking onto a pin within the motor operator. When the contacts are closed, thus indicating an “on” condition, the lever remains hooked onto the pin.Type: GrantFiled: December 27, 2000Date of Patent: December 17, 2002Assignee: General Electric CompanyInventors: Randall Lee Greenberg, Roger Neil Castonguay, Thomas Frederick Papallo, Jr.

A first level quality matrix is generated identifying an effect at least one first level key control parameter has on at least one first level critical to quality parameter. The first level key control parameters are arranged into a first group and a second group. A second level quality matrix is generated for the first group. The second level quality matrix includes second level critical to quality parameters corresponding to the first group of first level key control parameters and a second level key control parameter. The second level quality matrix identifies an effect said second level key control parameter has on at least one second level critical to quality parameter.Type: GrantFiled: May 14, 1999Date of Patent: February 26, 2002Assignee: General Electric CompanyInventors: Mohamed Ahmed Ali, Bharat Sampathkumaran Bagepalli, Bijan Dorri, Thomas Gerard Ebben, Aniruddha Dattatraya Gadre, Michael Solomon Idelchik, Khan Mohamed Khirullah Genghis Khan, Brian Douglas Lounsberry, Arlie Russell Martin, Thomas Frederick Papallo, Jr., Mark Alan Preston, Raymond Kelsey Seymour, Douglas J.
