Patent CA-2288486-A1 (CA)
Inventor: MIYA KAZUYUKI
IPC: H04W28/18
Filed: 1999-11-03
Abstract: Calculation circuit 201 calculates the difference between the channel estimated value of a known reference signal sent from antenna A of the base station and the channel estimated value of a communication channel signal sent from the antenna of the base station, and the difference between the channel estimated value of a known reference signal sent from antenna B of the base station and the channel estimated value of the communication channel signal sent from antenna of the base station. These differences of channel estimated values are sent to comparison circuit 202 and compared there. This comparison result is sent to determination circuit 203. Determination circuit 203 performs threshold determination on the comparison result. The antenna that sent the communication channel signal is estimated by this threshold determination. Weighting calculation circuit 204 finds weighting factors based on the comparison result and determination result.

Title: Cardiac tissue ablation device and method of use
Inventor: LESH MICHAEL D
IPC: A61B17/22
Filed: 1998-05-11
Abstract: A tissue ablation device creates long linear lesions along a body space wall of an animal, and primarily between adjacent pulmonary vein ostia in a left atrial wall. An ablation element includes first and second ends that are bordered by first and second anchors. The anchors are adapted to secure the ablation element ends at predetermined first and second locations along the body space wall such that the ablation element is adapted to ablate an elongate region of tissue between those locations. The anchors may be guidewire tracking members, each including a bore adapted to receive and track over a guidewire, and may anchor within adjacent pulmonary vein ostia when the engaged guidewires are positioned within the respective veins. Stop members may be provided on the guidewires and may be adapted for positioning the relative anchors or for forcing the anchors to fit snugly within the vein ostia. A conduit passageway through the catheter houses a stiffening stylet which may be advanced into the region of the ablation element in order to impart a shape to that element to conform it to a predetermined region of anatomy, or to stiffen the underlying catheter in order to advance the assembly into remote anatomy.

IPC: H04B7/26
Filed: 1999-11-15
Abstract: The system enables the battery power to be conserved when there is no received speech signal. The circuit for reception of speech signals in a mobile telephone (1) operates with speech signals which are distributed in time windows situated in successive frames. The process includes the reception of the first speech signals corresponding to a first time window. This is followed by measurement of quality information relating to the received speech signals and comparing this with a first threshold. The mobile telephone is then configured to receive, or not receive, the second speech signal corresponding to a second time window as a function of this comparison.

Patent CA-2316722-A1 (CA)
Inventor: WEAVER CARL FRANCIS
IPC: H04B1/04
Filed: 2000-08-25
Abstract: A method and apparatus to quickly adjust a targeted E b/N0 (270, 470) in a wireless communication system by using an effective E b/N0 (310, 510) for each frame.  The E b/N0 distribution of a frame produces a certain frame error rate. Effective E b/N0 (310, 510) is the E b/N0 that would produce the same frame error rate in a model channel, such as an additive white Gaussian noise (AWGN) channel. The effective E b/N0 (310, 510) for each frame is obtained and compared to a model targeted E b/N0 (250, 480). The E b/N0 for all of the power control groups in one frame compose the vector E b/N0 (300, 500). The effective E b/N0 (310, 510) for the frame is obtained by mapping a vector E b/N0 (300, 500) into a scalar. The model targeted E b/N0 (280, 480) is the E b/N0 value that produces a desired frame error rate in the model channel. The targeted E b/N0 (270, 280) is increased by one up step size when the effective E b/N0 (310, 510) is smaller than the model targeted E b/N0 (280, 480) and is decreased by one down step size when the effective E b/N0 (310, 510) is larger than the model targeted E b/N0 (280, 480). E b/N0 (290, 490) are measured for each power control group in a frame.  The wireless communication system includes a transmitter (400) to transmit a signal, a receiver (320) to receive the signal, and an outer control loop (250, 450) to adjust the targeted E b/N0 (270, 470) based on a comparison of the effective E b/N0 (310, 510) of the signal to the model targeted E b/N0 (280, 480). Preferably, the outer control loop (250, 450) is implemented in software, although it can be implemented in hardware. Obtaining an effective E b/N0 (310, 510) for each time period allows quicker adjustments of the targeted E b/N0 (270, 470). This permits the targeted E b/N0 (270, 470) to be closer to an E b/N0 that produces a desired frame error rate, especially if the mobile is moving. This allows the transmitted power to be closer to the power needed to produce the desired frame error rate, permitting an increase in the capacity of the wireless communication system while still maintaining an acceptable number of errors.

Title: Coating structure having corrosion resistance
Inventor: MURATA HIROYUKI
IPC: C23C22/56
Filed: 2000-08-30
Abstract: The coating structure having a corrosion resistance of the invention contains a formation film formed on the surface of an aluminum alloy material. The formation film is subjected to a zirconium phosphate treatment. Because the zirconium phosphate reacts with an oxide film on the surface of the aluminum alloy to form a zirconium boehmite layer and to increase the adhesion of the coating material, a corrosion resisting structure is obtained without need of a sealing treatment while restraining the increase of the product cost. Also, a primer layer is formed on the outer surface of the formation film and the primer layer is composed of phosphomolybdic acid.
