Abstract: Disclosed is a method for controlling uplink and/or downlink transmission rate between a mobile station and a base station according to transmission power of the mobile station/base station in a communication system. First, a transmission power measurement device measures transmission power of the mobile station/base station. Then, the transmission power measurement device compares the measured transmission power with predefined thresholds to determine whether an event happens. At last, if an event happens, a rate adjustment controller sends a rate adjustment demand according to type of the event to adjust the uplink and/or downlink transmission rate.

Abstract: An energy saving electromagnet with momentary demagnetization of this invention comprises an armature, an iron core, an exciting coil, and a controllable power source. It is provided with an energy storage means capable of generating a momentary rotation force to cause the armature to rotate slightly for momentary demagnetization after the power source is cut off. The controllable power source includes an initiation power source, a holding power source and a control circuit for turning the supply from the initiation source to the holding source, thereby enabling effective utilization of the electric power and reduction of magnetic resistance. In the holding state, there is no significant demagnetizing air gap between the armature and the iron core.
