摘要:
In order to collect performance information of a computer capable of executing more than one application software, collection information indicating a timing at which the performance information is to be collected is prepared by the unit of application software. This collects the performance information by referring to the collection information corresponding to the application software currently being executed by the computer. Such a manner collects the performance information at an appropriate timing suitable to the application software currently being executed.

Random accesses are regulated in a radio-assisted local network having at least one access point, a reachable radio station located in the radio coverage area of the at least one access point, at least one remote radio station located outside the radio coverage area of the at least one access point and inside the radio coverage area of the reachable radio station. The at least one access point temporarily allocates radio resources, for sending information, to radio stations inside the radio coverage area. The reachable radio station sends a signal to the at least one remote radio station, containing information on the permissibility of random access by the at least one remote radio station to the radio resources of the at least one access point.

Provided is a cross-domain parallel recovering method and system in multi-layer and multi-domain distributed optical network (MMDON). Based on inter-domain LRA (Link Recovery Algorithm), the routing devices establish inter-domain WP (Work Path) and then build inter-domain RP (Recovery Path) based on WP. Inter-domain RPs will be established by using PSM (Parallel Signaling Mechanism) when link failure occurs on inter-domain WPs. That realizes the establishments and of inter-domain RP, and improves the survivability of inter-domain services. Inter-domain RPs are established or engaged before the establishing of WPs, while the intra-domain paths are established after the failure testing. This mechanism ensures the availability of inter-domain resources during recovery and avoids resource waste caused by pre-establishing intra-domain RPs. Moreover, parallel signaling mechanism can decrease the recovery time, and can handle inter-domain link failures simultaneously to avoid queue-waiting.

The present invention relates to an adaptive digital predistortion device and method. The adaptive digital predistortion device comprising: a predistortion unit for predistorting an input signal according to a predistortion parameter stored in a look-up table; a cost function generation unit for generating a cost function; a fixed segment point determination unit for determining a fixed segment point; and an update unit for updating parameters (u1, u2, ka) according to the cost function to update the look-up table based on the updated parameters (u1, u2, ka), wherein ka is an updated adaptive segment point, u1 and u2 are slopes on two sides of the adaptive segment point ka; and for subsequently updating parameters (v1, v2) according to the cost function to update the look-up table based on the updated parameters (v1, v2) and the fixed segment point, wherein v1 and v2 are slopes on two sides of the fixed segment point. Therefore, the adaptive digital predistortion device according to the present invention can obtain a good performance within an acceptable convergence time by combining the adaptive segment with the fixed segment.
摘要:
A reader and method for adjusting the transmission time of a continuous wave (CW), wherein the method comprises setting an initial value for a response waiting time, sending the CW to a tag after sending a command to the tag and waiting for a response from the tag, judging whether the response from the tag is received within the response waiting time. If the response from the tag is received within the response waiting time, then sending of the CW is stopped and the response waiting time is adjusted. If the response from the tag is still not received beyond the response waiting time, then sending of the CW is stopped. The time for the reader to wait for a response from the tag is far less than 20 ms. Consequently, a command failure can be found early, so as to improve the processing efficiency of an RFID system.

A far-field radio frequency (RF) telemetry system for communicating with an implantable medical device includes a diversity antenna system. Multi-frame messages each including multiple outgoing data frames are transmitted to the implantable medical device. In response, the implantable medical device transmits response data frames each following one or more of the outgoing data frames, according to a predetermined communication protocol. An antenna control circuit selects an antenna of the diversity antenna system for transmitting the outgoing data frames and/or receiving the response data frames based the quality of signal reception associated with the response data frames.
