Patent number: 7828132Abstract: An electric clutch actuator capable of operating in two power loss conditions. For a condition where a normally engaged clutch is disengaged during a system power loss and the desired action is for the clutch to remain in the disengaged positional state, a holding device moves to a power off activated position to prevent movement of an actuator for the clutch. For a condition where the clutch is disengaged during a system power loss and the desired action is for the clutch to move to an engaged positional state, a motor in the electric clutch actuator is used as a generator to convert the potential energy of a clutch pressure spring into electrical energy to provide energy for powering the holding device to remain deactivated, permitting movement of the clutch actuator to the engaged position. Maintaining the holding device deactivated permits the clutch to move to the engaged position and thereby allows vehicle engine braking to be used during a power loss of the system.Type: GrantFiled: February 26, 2007Date of Patent: November 9, 2010Assignee: Globe Motors, Inc.Inventors: Brett E. Swensgard, Syed A. Hossain

Patent number: 7215958Abstract: The present invention relates to a relocation method, system and network element for changing a serving radio resource control entity After an initial operating state in which a user equipment (30) has radio links with a serving network element (20) and a drift network element (21) supporting said serving network element (20) with a wireless connection, the serving network element (20) transmits a relocation-specific information to a target network element (22). Based on the relocation-specific information, the target network element (22) establishes a link to the drift network element (21), such that the drift network element (21) can receive user traffic from both the serving network element (20) and the target network element (20). Then, the radio resource control is relocated to the target network element (20). The relocation-specific information may comprise an identifier or a list of identifiers of drift network elements.Type: GrantFiled: August 20, 2001Date of Patent: May 8, 2007Assignee: Nokia CorporationInventors: Andras Kovacs, Shavantha Kularatna, Atte Länsisalmi, Gabriel Ramos, Syed Hossain, Pekka Korja, Raquel Sanchez, Sanna Mäenpää

Patent number: 7213661Abstract: A rotary cone rock bit includes one or more hole cleaning nozzles and one or more bit cleaning nozzles. The hole cleaning nozzles of one drill bit define a projected fluid path disposed at a lateral angle of less than six degrees in order to achieve a large impingement pressure on the hole bottom. The bit cleaning nozzles of the same drill bit define a projected fluid path disposed at a lateral angle of at least six degrees in order to pass within 0.5 inches of the teeth on leading edge of the lagging roller cone. This results in a drill bit that both cleans the bottom hole and cleans cone inserts.Type: GrantFiled: December 5, 2003Date of Patent: May 8, 2007Assignee: Smith International, Inc.Inventors: James L. Larsen, Dwayne P. Terracina, Syed Hossain

Patent number: 7042189Abstract: In one method for controlling an electric motor, current turn-on and turn-off rotor-position angles for each motor phase are chosen to substantially maximize the absolute value of average motor torque when the motor is operating in two different quadrants of motor torque and motor speed. The first quadrant has positive motor torque and positive motor speed. The second quadrant has negative torque and positive speed. The third quadrant has negative torque and negative speed. The fourth quadrant has positive torque and negative speed. In another method, the motor is operated in at least one of the first and third quadrants and in at least one of the second and fourth quadrants, wherein the absolute value of motor speed is limited when the motor is operating in the first or third quadrants but not in the second or fourth quadrants. In one example, the motor operates a vehicle brake caliper.Type: GrantFiled: April 30, 2002Date of Patent: May 9, 2006Assignees: Delphi Technologies, Inc., The University of AkronInventors: Syed A.
