Title: Selecting an access point according to a measure of received signal quality
Inventor: MYLES ANDREW F
IPC: H04W84/12
Filed: 2004-07-13
Abstract: An apparatus for inclusion and a method for operation in a station (STA) of a wireless network. The method includes received data from at least one remote station and determining a measure of the signal quality, e.g., a measure of the EVM from samples of the data received from the remote station(s). If the remote station(s) is/are access point(s), the station selects an access point for association according to criteria that include the measure of the EVM from the remote station. If the received data includes a request management message, the station responds to the request management message with a response management message that include a measure of the EVM of the received data corresponding to the request management message. Thus, the remote station receiving the response management message receives an indication of the quality of the link between the station and the remote station without the receiving remote station necessarily being EVM-capable.

Patent CA-2568903-A1 (CA)
Inventor: JOKINEN HARRI
IPC: H04W36/14
Filed: 2005-06-02
Abstract: L'invention concerne un procédé de resélection de cellule par une station mobile, d'une cellules GERAN en service soutenue par un réseau d'accès radio GSM/EDGE (système mondial de communications mobiles/taux de données améliorées pour l'évolution globale) (GERAN) à une cellule UTRAN soutenue par un réseau d'accès radio terrestre universel (UTRAN). Dans un premier mode de réalisation de l'invention, le comportement de resélection intersystème désiré est obtenu sans changements de signalisation, ce qui peut constituer un mode préféré pour des mises en oeuvre rapides étant donné que les changements de signalisation mettent toujours plus longtemps à atteindre les produits sur le terrain (des mises à jour mobiles et de réseau sont normalement nécessaires). Dans un deuxième mode de réalisation, la flexibilité des changements de signalisation représente un avantage.

Abstract: A reciprocating syringe that can be used in connection with existing syringe barrels and fittings. Some embodiments comprise a frame, adapted to retain two existing syringe barrels. The frame can accommodate fittings on one or both barrels. The invention also provides a plunger complex, comprising two plungers, each adapted for use with one of the syringe barrels. The two plungers are coupled such that pushing of each plunger into its barrel causes the other plunger to pull outwards relative to its barrel. The two plungers can be coupled by a flexible line attached to one plunger, routed from the plunger out of the corresponding barrel into the other barrel, and attached to the other plunger. The invention contemplates various frame configurations to accommodate desired line and pulley performance characteristics. Other embodiments comprise a frame adapted to retain an existing syringe barrel, and an auxiliary actuator mounted with the frame. Such an actuator can provide a syringe-like plunger operation, or can comprise other manipulable structures.  The auxiliary actuator can be coupled to a plunger adapted for use with the syringe barrel, such that pushing the plunger into the barrel causes the actuator to move in a reversible manner, and moving the actuator in the reverse manner causes the plunger to pull outwards relative to its barrel. The invention also comprises various materials, methods of making, geometries and arrangements of parts, and accommodation of various specific existing syringe designs and applications.
