  • Publication number: 20070291728
    Abstract: A method, terminal device, network element, system and computer program product for controlling discontinuous reception or transmission at a terminal device of a communication network are disclosed. A regular discontinuous reception or transmission cycle of a regular discontinuous reception or transmission scheme is set by using a first control layer, and in addition thereto a shorter temporary discontinuous reception or transmission cycle of an interim discontinuous reception or transmission scheme can be set by using a second control layer. This arrangement provides long discontinuous reception or transmission cycles for power consumption improvements while at the same time ensuring that the network can easily and flexibly shorten these cycles for increased data throughput, if needed.

  • Publication number: 20070230418
    Abstract: A new and unique method or apparatus for implementing an unscheduled automatic power save delivery (U-APSD) in a wireless local area network (WLAN) terminal, comprising maintaining a timer for defining a triggering interval between sending of subsequent trigger frames to a WLAN access point, wherein the value of the timer is set to dynamically change according to one or more criteria relating to the current communication situation. The criteria depend on whether there are buffered frames. at another node, point, terminal or device, such as an Access Point (AP)), in the wireless local area network (WLAN), or other suitable network. For example, when there are buffered frames at the AP, the WLAN terminal sets the triggering interval to a minimum value and sends null-data frames to quickly retrieve them, or when there is no buffered frame at the AP, the STA sets the triggering interval to a larger value to continue the doze mode for a long time and to save energy.

  • Patent number: 6989683
    Abstract: Improved endpoint detection is obtained for wet etch and/or other chemical processes involving in situ measurement of bath impedance. The endpoint detection uses a measurement apparatus having a measurement circuit with a capacitor designed to alter the phase angle of the circuit. The capacitor is preferably a variable capacitor which is used to set the initial phase angle of the measurement circuit to about zero. The methods using the improved detection enable etch to be more precisely controlled even under conditions where noise would otherwise adversely impact determination of the endpoint.

  • Publication number: 20050129000
    Abstract: A node selecting method is characterized by comprising a first step of reserving a communication band on a route by seeking a communication route from a source node to a destination node through intermediate nodes by use of an ad-hoc on-demand distance vector (AODV) algorithm in a mobile ad-hoc network; a second step of storing information on communication bandwidth of a link route connecting each pair of neighboring intermediate nodes on the communication route in the intermediate nodes; and a third step of collecting information on available communication bandwidth of the communication route and transmitting it to the source node when a route reply is made from the destination node on the communication route toward the source node.
