Abstract: Provided is a method, system, and computer program product for managing tasks in a computing system using a virtual node. A processor may register a virtual node for handling tasks allocated by a scheduling node in a computing system, the computing system comprising the scheduling node and a group of actual computing nodes processing tasks allocated by the scheduling node, and the scheduling node takes the virtual node as an actual computing node. A performance level of the computing system is obtained. Capacity of the virtual node is set based on the obtained performance level, such that the scheduling node allocates tasks to the virtual node based on the capacity of the virtual node. In response to at least one task being allocated by the scheduling node to the virtual node, the at least one task is received by the virtual node.

Abstract: The hidden node problem can be avoided by scheduling stations in different sectors to perform transmissions during different time periods. Sectorized scheduling can be communicated to stations through transmission of beamformed beacon signals at the beginning of respective time periods. For instance, a first beamformed beacon signal may be transmitted to stations in a first sector at the beginning of a first time period, while a second beamformed beacon signal may be transmitted to stations in a second sector at the beginning of a second time period.

Abstract: A system and method of ANQP querying using a common ANQP group version. One embodiment of the method includes associating an original common ANQP group version with a common ANQP group, transmitting a message containing the original common ANQP group version to at least one station, associating a new common ANQP group version with the common ANQP group when an element therein is changed, and transmitting another message containing the new common ANQP group version to the at least one station.

Abstract: The present invention provides an eccentric roundel structure for three-compressing-chamber diaphragm pump. The eccentric roundel structure is a truncated-cylinder eccentric roundel in an eccentric roundel mount. The truncated-cylinder eccentric roundel characteristically comprises an annular positioning dent, a truncated cylinder peripheral and a sloped top ring created from the annular positioning dent to the truncated cylinder peripheral to replace a conventional rounded shoulder. By means of the sloped top ring, the oblique pull and squeezing phenomena of high frequency incurred by the rounded shoulder in a conventional tubular eccentric roundel are completely eliminated. Thus, not only the durability of the three-compressing-chamber diaphragm pump for sustaining the pumping action of high frequency from the truncated-cylinder eccentric roundels is mainly enhanced but also the service lifespan of the three-compressing-chamber diaphragm pump is exceedingly prolonged.

Abstract: Network signaling loads are controlled in a wireless network by monitoring traffic patterns at an access point and determining that the access point is a high turnover access point. A high turnover access point is determined based on an average time devices spend in a coverage area of the access point being below a threshold level. Beacon and/or probe response messages are generated that identify the access point as a high turnover access point. In addition, a turnover activity value may be generated for the access point and included in the beacon and/or response messages. A mobile device may determine whether to authenticate and associate with the access point based on the turnover activity value.

Abstract: A four-compression-chamber diaphragm pump with multiple effects includes an eccentric roundel mount with four cylindrical eccentric roundels, a pump head body with four operating holes, and a diaphragm membrane with four annular positioning protrusions. A basic curved groove or other vibration-reducing first positioning structure is circumferentially disposed around each operating hole while a basic curved protrusion or other second vibration-reducing second positioning structure is provided in the diaphragm membrane for suitably coupling with the corresponding groove or other first positioning structure upon assembly, resulting in a shortened length of moment arm from the basic curved protrusions or other vibration-reducing positioning structures to respective downwardly-extending annular positioning protrusions in the diaphragm membrane, and consequently reduced vibration noise and resonant shaking in comparison with a conventional four-compressing-chamber diaphragm pump.

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.

Abstract: A roundel structure for a five-compressing-chamber diaphragm pump includes a cylindrical or inverted frustoconical eccentric roundel in an eccentric roundel mount. The cylindrical or inverted frustoconical eccentric roundel includes an annular positioning groove or indentation, a vertical or inverted frustoconical flank and a sloped top ring extending from the annular positioning groove or indentation to the flank. The sloped top ring eliminates the oblique high frequency pull and squeezing phenomena that occurs in a conventional tubular eccentric roundel arrangement.
