Filed:

Dec 14, 2009

Appl. No.:

12/636831

Inventors:

David Burnham - Berkley MI, US

Assignee:

Robert Bosch GmbH - Stuttgart

International Classification:

G06F 7/00
G06F 17/00
G05D 9/12
B60K 1/00

US Classification:

701 36, 701 49, 700295, 180 658

Abstract:

An electronic control module for a vehicle. The electronic control module includes a housing, a temperature sensor positioned in the housing, and a controller positioned in the housing and coupled to the temperature sensor. The controller includes a processor, a memory, and a plurality of switches. The controller performs a first function related to a comfort level of an occupant of the vehicle at a first level of functionality. The controller also detects a temperature in the housing, and modifies the first function when the detected temperature exceeds a temperature threshold. The modification of the first function reduces a quantity of heat generated by the controller.

International Classification:

H02H 3/00

US Classification:

361 86, 361 84

Abstract:

Systems and methods of diagnosing a condition of a reverse-voltage protection switch in an electric system. The electric system includes a power source, an electric load, and a reverse-voltage protection switch in a series-type configuration. The electric system further includes a ground switch configured to selectively connect the source terminal of the reverse-voltage protection circuit to ground. The terminals of the reverse-voltage protection circuit are disconnected from the power source. The ground switch is closed to connect one terminal of the reverse-voltage protection switch to ground. A bias voltage is applied to the other terminal of the reverse-voltage protection switch and the reverse-voltage protection switch is opened. An improper short-circuit condition across the reverse-voltage protection switch is detected when the voltage at the biased terminal of the reverse-voltage protection switch is less than a threshold when the reverse-voltage protection switch is opened.

International Classification:

B23K 1131

US Classification:

219 89

Abstract:

A shut off check valve for controlling cooling fluid flow to weld tips of a resistance welding gun. The valve is disposed within the weld gun housing and selectively interrupts cooling fluid flow between fluid inlet and outlet ports.
