  • Patent number: 8845309
    Abstract: The present invention provides a vibration reducing device for pump cover body of water shut-off diaphragm pump comprising a hood cover mount and a pump cover body with a containing pit, which orderly accommodates a plastic elastic membrane disk, an obstructing baffle and a compressed spring therein. The plastic elastic membrane disk includes a downward central flow directing buffer, which can insert into a flow directing compartment in the containing pit when the hood cover mount docks with the pump cover body. The flow directing buffer can not only absorb the direct impacting momentum of pumped high pressurized water to the surrounding internal wall of the flow directing compartment but also redirect the random impacting direction of the high pressurized water. Thus, the vibration of the pump cover body with annoying noise created by the impacting momentum of the high pressurized water is deleted.

  • Publication number: 20140112325
    Abstract: An extension to the Access Network Query Protocol (ANQP) protocol allows stations (STAs) to discover multiple APs via a single ANQP request/response exchange. A STA can send a single ANQP request message to request information for multiple APs, e.g., two or more neighboring APs. The receiving AP may retrieve discovery information for one or more neighboring APs, and send an AP response message including the retrieved discovery information to the requesting STA. The ANQP request message identify the multiple APs for which discovery information is sought, and may specify which information is being requested for that corresponding AP.

  • Publication number: 20140098804
    Abstract: Embodiments are provided for identifying transitory WiFi users and providing a differential treatment of such users in terms of delaying associating steps between user stations (STAs) and an access point (AP). A transitory user refers to a user or user device that connects to a WiFi AP but does not run applications that require association or assigning IP addresses, such as short-term or temporary connected WiFi users that are on the move. In an embodiment, a STA connects to an AP. Upon the STA indicating its transitory behavior to the AP or the AP detecting criteria of transitory behavior of the STA, the STA obtains a delay time value from the AP. The STA then delays sending an association request to the AP, or alternatively, the AP delays handling the association request from the STA in accordance with the delay time value.

  • Publication number: 20140010089
    Abstract: It is possible to shorten channel monitoring periods of unoccupied channels during Wi-Fi discovery by verifying whether or not a message indicating the presence of a Wi-Fi AP has been detected prior to the probe timer reaching a medium channel time (MedChannelTime). For example, STAs detecting some channel activity during the clear channel assessment may nevertheless discontinue monitoring a Wi-Fi Channel when no messages indicating the presence of a Wi-Fi AP are detected prior to expiration of the MedChannelTime. Messages indicating the presence of a Wi-Fi AP may include any Wi-Fi messages sent from or destined for a Wi-Fi AP, while excluding probe requests and non-Wi-Fi messages.
