Patent number: 9362544Abstract: Disclosed herein are systems and methods for control of a current interruption component in a battery system. Various embodiments consistent with the present disclosure may include a detection system configured to detect an event (e.g., an impact event, a resistive short, a coolant leak, etc.) and a control system configured to receive information from the detection system and to generate a control signal based upon detection of the event. The control signal may selectively actuate an electrical clearing component. A current interruption component may be configured to selectively interrupt a flow of current upon an occurrence of a condition that results from actuation of the electrical clearing component. Upon detection of the event by the detection system, the control system may generate the control signal to actuate the electrical clearing component, and the actuation of the electrical clearing component may trigger the current interruption system.Type: GrantFiled: February 26, 2013Date of Patent: June 7, 2016Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Paul W. Kelley, Andrew K. Chandler, Brian J. Martel

Patent number: 9327610Abstract: A system and method for individually discharging battery cells in a high voltage vehicle battery. The system includes a battery controller that monitors and controls the state-of-charge of each of the battery cells and a cell balancing circuit for maintaining the charge of the cells substantially equal. The controller receives a signal from a vehicle crash detector indicating that the vehicle has been in a crash, and in response instructs the cell balancing circuit to discharge all of the battery cells.Type: GrantFiled: September 12, 2012Date of Patent: May 3, 2016Assignee: GM Global Technology Operations LLCInventors: Peter Andres, Ryan M. Frakes, Paul W. Kelley

Publication number: 20160097788Abstract: A technique for automatically determining direction of motion of a pedestrian is described. In embodiments, accelerometer measurements obtained from an accelerometer of a mobile device are converted from a mobile device reference frame to a local level reference frame. The local level accelerometer measurements are filtered to obtain a first series of frequency components representing acceleration at an estimated stride frequency of the pedestrian in a first direction and a second series of frequency components representing acceleration at the estimated stride frequency of the pedestrian in a second direction that is orthogonal to the first direction. A heading angle of a major axis or semi-major axis of an ellipse defined at least by one or more frequency components in the first series and one or more frequency components in the second series is then determined The direction of motion of the pedestrian is determined based on the heading angle.Type: ApplicationFiled: April 29, 2015Publication date: April 7, 2016Inventors: Douglas P. Looze, Paul W. Kelley

Patent number: 7882702Abstract: An engine system and method for operating an internal combustion engine includes a turbocharger that generates a boost to the engine. A coolant temperature of the engine is determined along with other based engine inputs and calculated values. A normal boost based on operating conditions of the engine is determined. A supplemental boost is determined based on the coolant temperature. An offset boost based on the normal boost and the supplemental boost is determined. An air output of the turbocharger is modified based on the offset boost. The supplemental boost increases combustion efficiency, which reduces white smoke exhaust.Type: GrantFiled: December 30, 2004Date of Patent: February 8, 2011Inventors: Jamison C Schroeder, Jeffrey Johnson, Paul W Kelley, James S Baumgartner, Thomas L Bahensky, Scott John Fletcher, Mark L DeJong, Jose L DeLeon, Brent M Chamberlain

Patent number: 7200995Abstract: A control system and method for increasing engine temperature for an engine having a variable nozzle turbo (VNT) is provided. An offset idle module generates an offset idle signal. A normal boost module calculates a normal boost. A supplemental boost module calculates a supplemental boost. An offset boost module generates an offset boost signal for the VNT based on the normal boost and the supplemental boost. A control module adjusts engine idle and VNT boost based on the offset idle signal and the offset boost signal.Type: GrantFiled: December 30, 2004Date of Patent: April 10, 2007Assignee: General Motors CorporationInventors: Jamison C Schroeder, Jeffrey Johnson, Paul W Kelley, James S Baumgartner, Scott John Fletcher, Thomas L Bahensky, Mark L Dejong, Jose L Deleon, Brent M Chamberlain

Patent number: 6147998Abstract: An apparatus and method for determining the QoS of a communication system. In one embodiment a service verification equipment device (SVE) is placed into the communications link between the wide area network and the transmitting customer premise and an SVE is placed into the communications link between the wide area network and the receiving customer premise. The transmitting SVE inserts a test cell into the customer's data stream over communications link which informs the receiving SVE that a test is commencing. After a predetermined number of customer data cells are sent, the transmitting SVE inserts a termination cell into the communications link at the end of the test. The receiving SVE then compiles data related to the QoS of the communications link and that data is analyzed to determine the QoS.Type: GrantFiled: December 17, 1997Date of Patent: November 14, 2000Assignee: Visual Networks Technologies, Inc.Inventors: Paul W. Kelley, Stuart P. MacEachern, Ralph L. Beck

Patent number: 5465254Abstract: An optical fiber ring network carries data in frames of bit intervals that define a number of independent communication bands each represented by a series of spaced apart bit intervals no more than one of which falls within any given frame. The network serves a collision detection protocol by nodes that communicate with the user devices in accordance with the collision detection protocol but communicates with the ring in accordance with a non-collision type protocol. The network uses light that is amplitude modulated at more than two levels. The data frame boundaries are defined by violations of an alternate mark inversion data encoding technique. Phase synchronization of two streams of frames is accomplished by sampling frames at times governed by a selected one of two frame boundary clocks derived respectively from the two frames.Type: GrantFiled: August 20, 1993Date of Patent: November 7, 1995Inventors: Philip D. Wilson, Richard D. Serafin, Paul W. Kelley, Tadeusz Witkowicz
