Patent number: 9341665Abstract: An apparatus for monitoring a high voltage isolation in a vehicle. The apparatus comprising a power conversion device for receiving a high voltage on a power bus. The power conversion device is configured to control a first switch for enabling a first known resistance to receive the high voltage and to measure a first voltage between a first node and a ground in response to the first known resistance receiving the high voltage. The power conversion device is further configured to measure a second voltage between a second node and the ground in response to the first known resistance receiving the high voltage and to determine a first leakage resistance between the first node and the ground based on at least the first voltage and the second voltage. The first leakage resistance indicating whether the high voltage is isolated from the ground.Type: GrantFiled: April 18, 2012Date of Patent: May 17, 2016Assignee: Lear CorporationInventors: George Kaminski, Richard J.

Patent number: 8971038Abstract: A coldplate for use with electronic components in an electric vehicle (EV) or a hybrid-electric vehicle (HEV). The coldplate includes a main portion having multiple raised features on a surface thereof. The raised features are configured for attaching the main portion to a printed circuit board having multiple electronic components attached thereto. The raised features are further configured for maintaining the printed circuit board in a spaced relation relative to the main portion to facilitate air flow between the printed circuit board and the main portion for dissipating heat generated by the plurality of electronic components. The coldplate also includes a protrusion extending from the surface of the main portion. The protrusion is configured for contacting one of the plurality of electronic components attached to the printed circuit board for dissipating heat generated by the electronic component.Type: GrantFiled: May 22, 2012Date of Patent: March 3, 2015Assignee: Lear CorporationInventors: Nadir Sharaf, Dilip Daftuar, George Kaminski, Venkat Yalamanchili, Richard J.

Patent number: 6654894Abstract: A method and system for controlling the power supply fan in a computer system. The speed of a power supply fan can be made directly proportional to the temperature of the power supply. The fan speed can also be controlled by a processor with software commands according to the temperature of the processor. The speed of the fan will be dictated by the higher of the two commands driving it. Therefore, the power supply fan can never be commanded by the processor to run at a lower speed than that required by its own thermal environment. A Fan Speed Control Circuit enables the computer system to command the power supply fan to run at a higher speed. The processor temperature can be monitored with a temperature transducer and analog signal conditioning circuitry.Type: GrantFiled: October 19, 2001Date of Patent: November 25, 2003Assignee: Hewlett-Packard Development Company, L.P.Inventors: George A. Kaminski, George F. Squibb

Patent number: 6291976Abstract: A structure and related method for generating phase enable signals for a multi-phase switching power supply with the characteristic that each signal has the same frequency, but each differs in phase relationship. The structure includes a clock circuit coupled to a shift register and clocking the shift register. The shift register has one of its outputs coupled to its shift input signal line. Clocking of the shift register with the clock circuit produces a series of phase enable signals, at the shift register's shift output signal lines, to be coupled to switching phases of a multi-phase switching power supply. The circuit easily adapts to varying number of phases of the multi-phase switching power supply by changing which of the several shift output signals couples back to the shift input signal.Type: GrantFiled: May 30, 2000Date of Patent: September 18, 2001Assignee: Compaq Computer CorporationInventors: George A.

Patent number: 4096967Abstract: An ecological easy-open can end is disclosed. The pull tab cannot be removed from the can end and discarded; rather it is pushed down and snapped in under the can end where its sharp edges cannot cut the user. The pull tab has a hole in it so that when it is down inside the can it does not interfere with the dispensing of the contents of the can.Type: GrantFiled: June 6, 1977Date of Patent: June 27, 1978Assignee: The Stolle CorporationInventor: Elton George Kaminski
