Patent CA-2393009-A1 (CA)
Inventor: THIBEAULT BRIAN
IPC: H01L33/38
Filed: 2000-11-22
Abstract: An LED with improved current spreading structures that provide enhanced current injection into the LED's active layer (14), improving its power and luminous flux. The current spreading structures can be used in LEDs larger than conventional LEDs while maintaining the enhanced current injection. The invention is particularly applicable to LEDs having insulating substrates (12) but can also reduce the series resistance of LEDs having conductive substrates. The improved structures comprise conductive fingers (20a, 20b, 22) that form cooperating conductive paths that ensure that current spreads from the contacts (19, 21), into the fingers (20a, 20b, 22) and uniformly spreads through the oppositely doped layers (15, 16). The current then spreads to the active layer (14) to uniformly inject electrons and holes throughout the active layer (14), which recombine to emit light.

Abstract: A deskew buffer 410 arrangement in a CDMA receiver allows for accurate combining of symbols from a plurality of demodulator fingers, 402 and 404, without any symbol losses when the data rate is changed. A single deskew buffer 410 is coupled to a plurality of demodulator fingers, each of which demodulate an assigned multipath. The symbols are written into the deskew buffer 410 according to a PN count value modified by a predetermined bit pattern. The demodulator finger is able to demodulate a plurality of data rates corresponding to a plurality of Walsh lengths. Each data rate is assigned a corresponding deskew index. The PN count value represents an address within the deskew buffer 410. The lower bits of the PN count, where the number of bits corresponds to the deskew index, are truncated and replaced with the predetermined bit pattern. In one embodiment the predetermined bit pattern is all ones.

Title: System and method for performing a single step cryoablation
Inventor: LENTZ DAVID J
IPC: A61M25/00
Filed: 2003-08-13
Abstract: A system for cryoablating target tissue at a treatment site includes a cryo-element mounted at the distal end of a cryo-catheter. A balloon catheter is provided having a U-shaped balloon attached thereon. The cryo-element is threaded onto a pre-positioned guidewire and advanced within the patient's vasculature until the cryo-element is positioned at the treatment site. Next, the balloon is threaded onto the guidewire and advanced within the patient's vasculature using the balloon catheter. At the treatment site, the U-shaped balloon is interposed between the cryo-element and the target tissue. Saline solution is pumped into the balloon causing the U-shaped balloon to expand and contact both the cryo-element and the surrounding target tissue. Next, a refrigerant is expanded to cool the cryo-element, which in turn, freezes the saline solution. The resulting "ice ball" extracts heat from surrounding tissue resulting in the cryoablation of a substantially circumferential portion of tissue.

Filed: 2003-09-23
Abstract: Bottle (10) having an improve bearing base (20) capable to fully accommodate and hold its reusable stopper (30) while keeping bottle's upright stability. The base inner walls are forming cup like seat that holds stopper at four sides (24) to keep stopper in place using elastic properties of plastic materials used for bottle and stopper, and friction between surfaces of bottle and stopper. The cup-like seat has a rounded entry (28) into the inner part of the bottle base, so stopper (30) can find its way into the cup-like seat easily. After the rounded entry, stopper's circumference is getting in touch with the inner walls of the recessed base (24) that are from that point gently conical. With further travel of stopper, until it is completely positioned within the base, the holding of a stopper is achieved by elastic deformation and friction between stopper and bottle's recessed base inner walls (24). This shape provides easy placing of stopper in the recessed base and room for fingers to take the stopper out. The stopper can also be placed in by putting the bottle base on the top of the stopper that is laid on some surface (table) with the hollow side up.
