摘要： A hardware overvoltage disconnecting circuit wherein a DC power supply module is disconnected from a power network when the AC power network is in the state of overvoltage. The circuit includes a disconnecting relay and a voltage detection circuit. The disconnecting relay is connected in series between an AC power network and a power factor correction circuit of a power supply module. A first sampling terminal of the voltage detection circuit samples the voltage of the AC power network between the AC power network and the disconnecting relay, and an output of the voltage detection circuit is connected to a control terminal of the disconnecting relay. When the AC power network is in the state of overvoltage, the disconnecting relay is disconnected and the power supply module is disconnected from the AC power network. When the voltage of the AC power network is normal, the disconnecting relay is connected.

摘要： A method and system of radio frequency (RF) power transmission among multiple wireless stations is provided. Control signals for switching a receiving station between a power reception mode and a data reception mode are generated. The control signals provide switching information about which of the modes to switch to, and timing of the switching. In the data reception mode, the receiving station processes an RF transmission from a sending station as a data communication. In the power reception mode the receiving station processes the RF transmission as energy radiation for powering the receiving station. One type of control signal for power mode switching is generated at the MAC layer of a receiving station and sent to the PHY layer of that station for power mode switching. Another type is RTS/CTS control signal exchanged between the sending and receiving stations.

摘要： The invention is a routing method for data in a personal area network. The personal area network includes a plurality of nodes. The method includes receiving a frame at a node, determining whether the node contains a routing table entry for the frame destination, and when the node contains a routing table entry, determining a route for the frame based on a first routing protocol. The method further includes, when the node does not contain a routing table entry for the frame destination, determining whether a route should be discovered for the frame destination, and when a route should not be discovered, determining a route for the frame based on a second routing protocol.

摘要： A system and method for controlling congestion using Request-to-Send (RTS) and Clear-to-Send (CTS) in a wireless mesh network are provided. A receiver in a congestion state sets a duration field value of congestion control in a CTS frame and transmits the CTS frame to a sender. In response, the sender retransmits an RTS frame to the receiver without transmitting data, after waiting for an RTS retransmission waiting time period corresponding to the duration field value. The congestion state information is broadcast to neighboring nodes. Therefore, the congestion control system using the CTS frame does not use a separate frame for the congestion control. And, all of the neighboring nodes can participate in the congestion control, increasing the network efficiency.
