Publication number: 20170285176Abstract: Methods and systems are provided for locating a vehicle. A locating device receives position data and determines an approximate position of the vehicle. A remote server reports a plurality of corrections factor for a respective plurality of locations which are buffered by a transmission server into a burst transmission. The transmission server transmits the burst transmission of the correction factors over a wireless data channel. A receiver receives the burst transmission from the transmission server and a correction device extracts a selected correction factor from the burst transmission based on the approximate position to determine a refined position of the vehicle.Type: ApplicationFiled: March 31, 2016Publication date: October 5, 2017Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: STEVEN R.

Publication number: 20050178660Abstract: The invention relates to a sputter arrangement with a magnetron and a target, with the magnetron and the target being movable relative to one another. The magnetron comprises a magnet system, which forms a quasi-rectangular plasma tube, whose two longitudinal sides have a distance C from one another. If target and magnet system are moved relative to one another by a path corresponding approximately to the distance C, the magnet system is laid out such that the width at the end of the plasma tube is smaller or equal to the diameter of the plasma tube. However, if the path of the relative movement is less than C, the magnet system is laid out such that the width d of the ends of the plasma tube is less or equal to twice the diameter of the plasma tube.Type: ApplicationFiled: March 10, 2004Publication date: August 18, 2005Inventors: Andreas Lopp, Andreas Jischke, Michael Geisler, Herbert Pfeiffer, Jorg Krempel-Hesse
