Patent number: 9054718Abstract: In one embodiment, a transceiver may set a first receive frequency of a first channel of the transceiver and a second receive frequency of a second channel of the transceiver. The transceiver may receive, during a first time interval, a first radio frequency (RF) signal on the first channel. The transceiver may determine that a first measured value indicative of a first detectable received RF signal on the first channel exceeds a first predetermined threshold, and in response, receive a first data frame on the first channel. The transceiver may receive, during a second time interval, a second RF signal on the second channel. The transceiver determine that a second measured value indicative of a second detectable received RF signal on the second channel exceeds the first predetermined threshold, and in response, receive a second data frame on the second channel.Type: GrantFiled: November 30, 2011Date of Patent: June 9, 2015Assignee: Atmel CorporationInventors: Tilo Ferchland, Sascha Beyer, Dietmar Eggert, Udo Walter

Patent number: 6796163Abstract: A method is for the leak-tightness and operational testing of a stop valve of a pneumatic suspension of a motor vehicle with gas springs, with at least in each case one active volume capable of being connected via the stop valve, the vehicle including at least one connectable pressure source, at least one connectable pressure sink and, for each axle, at least one measuring device determining the distance to the vehicle body, and also damping elements limiting the stroke of the respective gas spring. For this purpose, in a first step, with the stop valve open, a stroke, during which at least one damping element is compressed, is set on the individual gas spring. In a second step, after the closing of the stop valve, the individual gas spring is set to a part-stroke of its total stroke between the damping elements.Type: GrantFiled: May 22, 2002Date of Patent: September 28, 2004Assignee: DaimlerChrysler AGInventors: Eberhard Kutscher, Udo Walter

Patent number: 6374193Abstract: In a method for monitoring the functioning of a compressor, which charges a gas-filled accumulator chamber with a working pressure, the actual pressure prevailing in the accumulator chamber is measured and compared to a setpoint pressure. In response to a deviation in the actual pressure from the setpoint pressure, an error signal is produced. The comparison of the actual pressure and the setpoint pressure is carried out during the charging operation when the accumulator chamber is charged.Type: GrantFiled: January 19, 1999Date of Patent: April 16, 2002Assignee: DaimlerChrysler AGInventors: Eberhard Kutscher, Joachim Lang, Gerhard Lohrmann, Reiner Schneider, Udo Walter

Patent number: 6212451Abstract: It is proposed that a pneumatic suspension leveling system for vehicles with a compressor which can be turned on and off by a control device in function of demand, which compressor only needs to operate intermittently, with predetermined on-time duration, during normal operation, be improved with respect to its functional capacity. This problem is solved in accordance with the invention in that the control device of the pneumatic suspension leveling system varies the on-time duration of the compressor in function of the heat transfer conditions which prevail between the compressor and the air enveloping the latter.Type: GrantFiled: March 17, 1999Date of Patent: April 3, 2001Assignee: DaimlerChrysler AGInventors: Eberhard Kutscher, Joachim Lang, Gerhard Lohrmann, Reiner Schneider, Udo Walter
