Filed:

May 18, 2007

Appl. No.:

11/804506

Inventors:

David L. Juzswik - Commerce MI, US
Stephen Wieland - Commerce Township MI, US
Michael G. Oszust - Davisburg MI, US

Assignee:

International Classification:

B60C 23/00

US Classification:

340447, 340445, 731464

Abstract:

A system () is provided for monitoring a remote tire monitoring sensor. The system includes a tire-based unit () having a sensor () and transmitter () that receives power from a power supply () located within the tire-based unit (). The transmitter () transmits a signal () relating to a parameter measured by the sensor (). The system () further includes a controller () that evaluates the life of the power supply () by monitoring energy usage of the power supply () by counting the number of occurrences in which the energy usage is above a prescribed amount () and comparing the number of occurrences to an energy threshold ().

Edward Mazorowicz - Canton MI, US

International Classification:

H03K005/22
G01R031/08

US Classification:

324525000

Abstract:

A fault monitor for the load portion of an electrical circuit may be connected to an existing circuit by a single connection, and may detect flaws within the load portion of the circuit through the detection of changes in voltage through a resistor, caused by changes in current flow due to changing resistance within the load portion of the circuit.

STEPHEN SCOTT WIELAND - COMMERCE TOWNSHIP MI, US

International Classification:

G07C 9/00

Abstract:

A key fob includes: communicator(s), a battery, memory, and processor(s) configured to: find signal strengths of received polls; determine, based on the signal strengths, that the received polls have: (a) increased, (b) decreased, (c) leveled off; and if (a), issue a poll response; if (c), not issue the poll response.

International Classification:

B60L 11/18

US Classification:

320134

Abstract:

A battery management system, such as for a vehicle having an electrically powered motor that is powered by a plurality of high voltage lithium ion battery packs, includes a circuit operable to detect active isolation for high voltage lithium ion battery packs. The circuit includes a single bias switch and the circuit detects active isolation utilizing a ratio driven algorithm that takes into account analog voltages with the bias switch open and closed. The circuit utilizes a ratio threshold for acceptable isolation breakdown.
