    摘要： An electronic circuit for sensing an output of a sensor having at least one electrode pair and circuitry for obtaining and processing the sensor output. The electrode pair may be laid out such that one electrode is wrapped around the other electrode in a U-shaped fashion. The electronic circuitry may include, among other things, a line interface for interfacing with input/output lines, a rectifier in parallel with the line interface, a counter connected to the line interface and a data converter connected to the counter and the electrode pair. The data converter may be a current-to-frequency converter. In addition, the rectifier may derive power for the electronic circuit from communication pulses received on the input/output lines.

    摘要： A medical communication device and communication protocols. The medical device may include communication circuitry and a plurality of antennas connected to the communication circuitry. The plurality of antennas may be disposed in the medical device such that the medical device communicates in a plurality of directions. The medical device may communicate with an implantable device implanted with a patient. A protocol for communicating with the implantable device may include monitoring a first antenna in the medical device during a first time slot for a transmitted signal; monitoring a second antenna in the medical device during a second time slot for the transmitted signal after monitoring for the transmitted signal on the first antenna; and generating an acknowledgement when a signal is detected on the first antenna, second antenna or third antenna. The device may be powered by a secondary power supply during communication.

    摘要： A highly efficient access control system and method employing XACML standard based policies and rules provides high performance resource access control of information systems of large enterprises. The system and method extracts plain rules from the XACML policies, transforms the plain rules into atomic rules, and compresses and indexes the atomic rules for fast lookup and retrieval. Access requests are decomposed into atomic requests which are compressed using the same value mapping as the rules. Index keys derived from compressed atomic request triplets are used to look up applicable rules which are used to evaluate requests for access to information system resources.
