Tire pressure monitoring system with transition from stationary vehicle to moving vehicle conditions
Publication number: 20030131657Abstract: A tire pressure monitoring system monitors the periodic transmissions from each of the tire pressure monitoring sensors. If a particular sensor fails to report a counter is incremented. The count is compared to a limit, with a lower limit being set for when a vehicle is moving and a higher limit being set for when the vehicle is stationary. If the count exceeds the limit then it is determined that the particular transmitter is failing. When the vehicle transitions from stationary mode to moving mode the count is compared to limits. If the count is between two limits, then the count is reset to a lower number before the control monitors operation in moving mode. In this fashion, inaccurate identifications of a failed transmitter are reduced or eliminated by ensuring that the difference between the two limits does not result in an improper identification of a transmitter as failing when the vehicle transitions from stationary to moving mode.Type: ApplicationFiled: January 14, 2003Publication date: July 17, 2003Applicant: Siemens VDO Automotive CorporationInventors: John R.

Publication number: 20030131690Abstract: A machine for clamping material to be fastened and automatically installing screws has been disclosed through a method of a self loading barrel that also aligns the screw to be installed thus reliving the operator of the strain of holding an unstable screw in place during the driving phase. This machine also automatically provides the force needed to keep the fastener from stripping at the head driver connection point through its unique design and also reliving the operator of much of the work related strain associated with these operations. This tool also provides another benefit in its design by automatically clamping the material during the fastening operation, that would normally have to be done separately with another tool. Another embodiment permits single loading of fasteners into the barrel.Type: ApplicationFiled: January 16, 2002Publication date: July 17, 2003Inventors: Jeffrey S. Swanson, Eric S. Swanson
