Title: Method and apparatus for multi-channel reverse link outer-loop power control
Inventor: CHEN TAO
IPC: H04J13/00
Filed: 2002-09-24
Abstract: In a disclosed embodiment, a maintain and adjust threshold module (312) determines the desired signal to noise and interference ratio for a first channel by monitoring the received quality of that channel (348). Next, a delta computation module (314) produces a threshold delta (324), which is th en added to a base threshold (326) by way of an adder (310). The resulting sum is the outer-loop set point (322) that is used in a comparator (308). The comparator (308) compares a receive signal strength (306) with the outer-loo p threshold (322). The comparator output (360) is inputted to a generate up/do wn command module (316). The generate up/down command module (316) sends a down command to the mobile unit (100) if receive signal strength (306) is greater than the outer-loop threshold (322), otherwise it sends an up command.</SDOA B>

Title: Distal end for cryoablation catheters
Inventor: RIORDAN MATT M
IPC: A61B18/02
Filed: 2004-05-20
Abstract: A system and method for transferring heat requires a supply tube connected in fluid communication with a capillary tube. A tip member is positioned to surround the distal end of the capillary tube to create a cryo-chamber. In operation, a liquid refrigerant is introduced into the supply tube at a working pressure (e.g. 450 psia). The pressure is then significantly reduced on the liquid refrigerant as it transits through the capillary tube. The refrigerant then exits the distal end of the capillary tube, still in its liquid state.      Inside the cryo-chamber, at a pressure of less than about one atmosphere, the refrigerant transitions into its gaseous state. The resultant refrigeration causes heat to transfer into the cryo-chamber.

Patent CA-2482575-A1 (CA)
Title: Surgical stapling instrument incorporating a firing mechanism having a linked rack transmission
Inventor: SWAYZE JEFFREY S
IPC: A61B17/072
Filed: 2004-09-27
Abstract: A surgical stapling and severing instrument particularly suited to endoscopic procedures incorporates a handle that produces separate closing and firing motions to actuate an end effector. In particular, the handle produces multiple firing strokes in order to reduce the required amount of force required to fire (i.e., staple and sever) the end effector. A linked transmission reduces the required handle longitudinal length, yet achieves a rigid, strong configuration when straightened for firing. A traction biased firing mechanism avoids binding in driving this straightened linked rack in cooperation with an anti- backup mechanism, with a lockout mechanism that prevents releasing the closure trigger during firing. Furthermore, an external indicator gives feedback to the surgeon as to how far firing has progressed, as well as providing a manual retraction capability.
