Patent number: 8345565Abstract: A method and system for operating a wireless access point is disclosed. In an embodiment, a wireless access point determines whether bursty interference is present within the operating range of the wireless access point and then adapts a transmission characteristic in response to the determination. In an embodiment, the wireless access point determines whether bursty interference is present by changing at least one transmission characteristic and monitoring the resulting error rates. The presence of bursty interference can be detected if a lowering of the transmission rate causes an increase in the error rate. The increase in the error rate is a result of the lower transmission rate and corresponding longer transmission time for each frame, which in turn increases the likelihood that a frame will overlap with bursty interference.Type: GrantFiled: January 16, 2008Date of Patent: January 1, 2013Assignee: NXP B.V.Inventor: Olaf Hirsch

Publication number: 20120331559Abstract: The invention provides a secure and efficient resource management system and a corresponding method for managing resources of a product that is put on the market by a licensor via a distribution chain. In particular, the number of keys needed for managing said resources can be reduced. At the time that the product is released to the market the exact licensing conditions of the product need not be known yet. The licensing conditions and the associated configuration of resources of the product are managed via a second key which is provided to a licensee. The licensee, however, has no knowledge of the first key and the derivation function which generates said second key based on the first key. Therefore, it is ensured that the licensee cannot claim more resources of the product than the licensor allows.Type: ApplicationFiled: June 4, 2012Publication date: December 27, 2012Applicant: NXP B.V.Inventor: Hans de Jong

Publication number: 20120328113Abstract: A method of controlling a loudspeaker output comprises deriving an admittance function over time from the voice coil voltage and current. In combination with a delta function, the force factor of the loudspeaker and the blocked electrical impedance, the input-voltage-to-excursion transfer function over time is obtained. This is used to control audio processing for the loudspeaker thereby to implement loudspeaker protection and/or acoustic signal processing. The invention provides a modelling and control approach which is not based on a parametric model. As a consequence, it does not require prior knowledge regarding the enclosure (e.g. closed or vented box) and can cope with complex designs of the enclosure.Type: ApplicationFiled: June 7, 2012Publication date: December 27, 2012Applicant: NXP B.V.Inventor: Temujin Gautama
