Patent CA-2550394-A1 (CA)
Inventor: SMAVATKUL NATTAVUT
IPC: G08C17/00
Filed: 2004-12-14
Abstract: A mobile station (106) establishes a real time communication link via an access point (102) for carrying voice or other time-sensitive data. A WLAN  subsystem (204) of the mobile station is normally kept in a low power state.  Upon initiating a communication link the mobile station signals to the access point that unscheduled power save delivery mode will be used (614), and the access point reserves resources to assure the necessary quality of service.  The mobile station initiates a frame transaction by first powering up the WLAN  subsystem (712), acquiring the WLAN channel (407), and transmitting a polling frame. Upon successful receipt of the polling frame the access point prepares to reply with an aggregate response. The aggregate response commences by transmitting all data in an aggregate buffer, including both reserved and unreserved data buffers. Upon successful receipt of the aggregate response, the mobile station places the WLAN subsystem back into a low power state.

Patent CA-2556377-A1 (CA)
Inventor: WILSON JOHN R
IPC: E03D1/30
Filed: 2006-08-16
Abstract: A dual mode flush valve includes a handle assembly having a handle, a bushing and a plunger. The bushing has a sleeve with a passage therethrough for mounting the plunger for sliding and tilting. The passage is defined by first and second partially overlapping bores that coincide at the inner end of the sleeve and are spaced one above the other at the outer end of the sleeve. The bores define a horizontal plunger travel axis and an angled plunger travel axis. Depending on which direction the user actuates the handle the plunger will travel along one of these axes. Travel along the angled axis will lower the plunger tip, allowing earlier clearance of a relief valve and a reduced flow through the flush valve compared to actuation with the plunger travel along the horizontal axis.

Patent CA-2574112-A1 (CA)
Inventor: PARKER FRED T
IPC: A61F2/86
Filed: 2005-07-22
Abstract: A stent delivery system includes a stept having at least one eyelet and at feast one rivet and a holder supporting the stept, wherein the holder includes a first section having a first diameter and a second section having a second diameter. A sheath covers the stept and the holder. The rivets are attached to each of the eyelets. A first inner diameter of the stent at the position of the rivets is smaller than a second inner diameter of the stept at other positions because the rivets protrude inwardly. A shoulder is formed on the holder due to the difference between the first diameter and the second diameter of the holder. The shoulder is positioned distally adjacent the rivets. The shoulder interferes with the protruding rivets, thereby restraining the longitudinalmovement of the stept relative to the holder.  Although the sheathis pulled back, the stem does not jump out of the stem delivery system. As a result, the stem delivery system allows the stem to be released in a controlled manner upon its deployment.
