Patent number: 8208500Abstract: A latency control mechanism for a communication system provides a known constant end-to-end delay between an audio source and one or more end node destinations, even in the case where different paths are used to reach the end nodes.

Patent number: 8209543Abstract: The present invention relates to a method for watermarking a processing module. The processing module is designed to process an electronic signal and form a processed signal involving steps of applying a first functional operator to cause a significant alteration to the processed signal. The first operator is embedded in the processing module. Additionally, a second functional operator is provided to co-operate with the first operator-so the alteration is essentially cancelled. The second operator-is adapted to act as an extractable identifier serving as a watermark for the processing module. An advantage with the method is the fact that since the first and the second operators are implemented as functional processing blocks, conventional debugging tools cannot be used to attack the processing module.Type: GrantFiled: September 25, 2006Date of Patent: June 26, 2012Assignee: NXP B.V.Inventor: Philippe Teuwen

Publication number: 20120158356Abstract: Various embodiments relate to a system and related method of validating a distance based on a plurality of sensor measurements in a vehicle. A tamper-proof odometer system may comprise an odometer and a tamper-proof sensor that independently determine distances based on measurements of vehicle components. The tamper-proof sensor may maintain a non-modifiable count based on the angular rotation of a target wheel from which to calculate a vehicle's distance traveled. An odometer may maintain a count based on the rotation of a wheel mounted to the transmission. An electronic control unit (ECU) or dashboard control unit (DCU) may compare the distance derived from the odometer with the distance derived from the tamper-proof sensor by comparing the error to a defined threshold. When the error value is above the defined threshold, this may indicate that one or more of the components of the odometer system have been manipulated.Type: ApplicationFiled: December 17, 2010Publication date: June 21, 2012Applicant: NXP.
