Abstract: A method of operating a wireless access point having a configurable antenna system includes determining a transmission signal quality metric for a first station with the configurable antenna system in a first configuration, determining a transmission signal quality metric for a second station with the configurable antenna system in the first configuration, determining a transmission signal quality metric for a first station with the configurable antenna system in a second configuration, determining a transmission signal quality metric for a second station with the configurable antenna system in the second configuration, determining a viable set of antenna configurations for which the signal quality metric of each of the stations meets a minimum criteria and configuring the configurable antenna system to a configuration in the viable set when the wireless access point is not transmitting.

Abstract: A method for radio communication in a wireless local area network including at least one transceiver equipped with an antenna with a controlled directivity pattern, according to which, in addition to the assignment in advance of the threshold value of communication quality H0 corresponding to the minimum pre-specified communication quality, the current value of communication quality Qcur is periodically determined based on the signal being received, the threshold value of the communication quality Hmax (corresponding to the pre-specified maximum communication quality) is also additionally assigned in advance.

Abstract: A compound oil ring comprises flat rings and a tangential expander provided therebetween. The tangential expander comprises an annular integrally bent serpentine spring having vertically extending webs and horizontally extending flanges terminating in vertically extending bearing shoulders. Each vertically extending flange is bent so as to form at least one bend extending into the interior of the compound oil ring.

Abstract: The joint of the expander is formed by tooth-like portions of the side flanges of a U-shaped spring, bent inward and coiled into a ring.The device comprises a measuring gear which reels off the sinuous profiled spring from a spiral.The gear has a radial slot receiving the reciprocating cutters acting in conjunction with bending punches which bend the cut-off tooth-like ends of the spring, locked into a joint.
