    摘要： The present invention advantageously provides techniques to solve problems with combinatorial anonymous certificate management by addressing critical issues concerning its feasibility, scalability, and performance. Methods and procedures to manage IEEE 1609.2 anonymous and identifying cryptographic keys and certificates in the Vehicle Infrastructure Integration (VII) system are presented, along with methods for management of identifying and anonymous certificates in a partitioned Certificate Authority architecture designed to enhance vehicle privacy. Novel methods for vehicles to dynamically change an anonymous certificate for use while maintaining vehicle privacy are given. Refinements to basic combinatorial schemes are presented including probabilistic key replacement, rekey counter decrement, dynamic rekey threshold, geographic attack isolation and proofs of geographic position.

    摘要： Method and apparatus for automatic reception enhancement of hearing assistance devices. The present subject matter relates to methods and apparatus for automatic reception enhancement in hearing assistance devices. It provides a power estimation scheme that is reliable against both steady and transient input. It provides a TSM estimation scheme that is effective and efficient both in terms of storage size and computational efficiency. The embodiments employing a decision tree provide a weight factor between the omnidirectional and compensated directional signal. The resulting decision logic improves speech intelligibility when talking under noisy conditions. The decision logic also improves listening comfort when exposed to noise. Additional method and apparatus can be found in the specification and as provided by the attached claims and their equivalents.

    摘要： This application sets forth, among other things, a new approach for real time collection, discovery, and sharing of network and user information, which we refer to as Autonomous Collaborative Information Collection, Discovery, and Sharing (AC-CDS). It is autonomous because regular mobile users and devices act autonomously to collect information and make the information available to others. It is collaborative as the autonomous actions of the mobile users and devices help each other to discover the information they want.

    摘要： A receiving circuit comprises an A/D converter which converts a receive signal to a digital signal having a first data format at a sampling rate corresponding to twice the spreading bandwidth of the receive signal, an analog front-end interface which converts the first data format of the digital signal to a second data format, a searcher which detects a phase of the digital signal having the second data format to perform a synchronization capture and outputs a timing signal, an interpolation filter which samples the digital signal having the second data format at a sampling rate different from the sampling rate of the A/D converter, a rake receiver which detects the synchronism of a signal outputted from the interpolation filter based on the timing signal and a demodulator which demodulates a signal outputted from the rake receiver.
