Power saving is one of the key technology in mobile terminal design, and most design only focus on power saving in idle mode.

Furthermore, an LED driver with power saving functions becomes popular in order to meet the energy efficiency requirements in LED traffic sign and message sign applications.

So provincial grid corporations request the inferiors to predict the network load.

This article analyses the potential of battery conserving in-process power transmission, expatiates the feasibility of energy saving in application of battery-conserving implement in lighting system of Hangzhou Iron and Steel Company Group, introduces the operating principle of J-SAVER, the actual result and its range of application.

This paper investigated and analyzed the electronic resources of provincial radio and TV university,indicated the present situation and existing problems and put forward some suggestions.

11 distributed coordination function based wireless local area network(WLAN),a new downlink access scheme optimal power saving mode (OPSM) is proposed to solve the problem of over contention after beacon transmissions.
