Publication number: 20160216237Abstract: An ultrasonic sensor is disclosed for performing a propagation-time measurement in a liquid. The ultrasonic sensor includes an ultrasound transmitter and a deflecting element made of plastic, into which deflecting element the ultrasound pulses emitted by the ultrasound transmitter are conducted, which ultrasound pulses are deflected on a boundary surface within the deflecting element by reflection. A hermetically sealed air bag is arranged inside the deflecting element. A wall of the air bag forms the plastic/air boundary surface for reflecting the ultrasound pulses. The ultrasonic sensor may provide improved functional capability of the deflecting element over a long time period, while being economical to produce.Type: ApplicationFiled: September 8, 2014Publication date: July 28, 2016Applicant: Continental Automotive GmbHInventor: Manfred Roth

Patent number: 7876893Abstract: A logic circuit for calculating an encrypted dual-rail result operand from encrypted dual-rail input operands according to a combination rule includes inputs for receiving the input operands and an output for outputting the encrypted result operand. Each operand may comprise a first logic state or a second logic state. The logic circuit comprises a first logic stage connected between the inputs and an intermediate node and a second logic stage connected between the intermediate node and the output. The logic stages are formed to calculate the first or second logic state of the encrypted result operand from the input operands according to the combination rule and to maintain or change exactly once the logic state of the encrypted result operand, independently of an order of arrival of the encrypted input operands, depending on the combination rule, in order to impress the calculated first logic state or second logic state on the output.Type: GrantFiled: August 3, 2006Date of Patent: January 25, 2011Assignee: Infineon Technologies AGInventors: Antoine Degrendel, Winfried Kamp, Manfred Roth, Thomas Kodytek
