  • Publication number: 20120287783
    Abstract: A load balancing method for a wireless communication system, which has a backbone network, more than one Access Point connected to the backbone network and more than one client. In the method, the client transmits a Probe Request message to the more than one Access Point; the Access Point monitors its load. If the Access Point is under an overload situation, it transmits a Probe Response message to the client by the minimum transmitting power. If the Access Point is under normal load situation, it transmits a Probe Response message to the client by normal transmitting power. The client preferentially chooses the Access Point under normal load situation to access based on the signal strength of the received Probe Respond message. The method thus provides the client with a priority of the Access Points, wherein the Access Point under an overload situation has a lower priority.

  • Publication number: 20120095551
    Abstract: A method is provided for implanting a valve having at least one valve leaflet within the cardiovascular system of a subject. One step of the method includes preparing a substantially dehydrated bioprosthetic valve and then providing an expandable support member having oppositely disposed first and second ends and a main body portion extending between the ends. Next, the substantially dehydrated bioprosthetic valve is attached to the expandable support member so that the substantially dehydrated bioprosthetic valve is operably secured within the main body portion of the expandable support member. The expandable support member is then crimped into a compressed configuration and placed at a desired location within the cardiovascular system of the subject. Either before or after placement at the desired location, fluid or blood re-hydrates the substantially dehydrated bioprosthetic valve.

  • Publication number: 20120044855
    Abstract: A communication method in an automation system, wherein the system comprises an access point and client terminals that receive downlink data sent from the access point and send uplink data to the access point, and the data transmission is divided into a master multiple receiver aggregation phase and more than one slave multiple receiver aggregation phases. During the master multiple receiver aggregation phase, the access point aggregates the data to be sent to the plurality of client terminals into one packet for transmitting in the downlink, and during the slave multiple receiver aggregation phases, the access point aggregates data in which errors have occurred when being transmitted during the master multiple receiver aggregation phase into one packet for transmitting in the downlink. The method can have strict control, through the access point and over the uplink and downlink data transmission, thus enhancing the certainty during automation communication and further reducing the cycle time.
