Patent CA-2266582-A1 (CA)
Title: Method and system for mobile location estimation
Inventor: HOLTZMAN JACK M
IPC: H04W64/00
Filed: 1997-09-29
Abstract: The present invention relates to a method and system for mobile location estimation in which range measurements between the mobile station and a base station are discriminated as being either from a base station which is line of sight with the mobile station or a base station that is non-line of sight with the mobile station (22). Non-line of sight error present in range measurements from base stations that are non-line of sight with the mobile station is corrected (24). A reconstructed line of sight range measurement is established from the correction of the non-line of sight error. The reconstructed line of sight range measurements can be used with range measurements of base stations determined to be line of sight for accurately locating the mobile station (26).

Inventor: HAZLEWOOD MICHAEL C
IPC: D06M13/02
Filed: 1999-06-29
Abstract: A method for imparting permanent press properties to a textile containing cellulose fibers. The method involves applying an aqueous solution of a (hydroxyalkyl)urea and/or a .beta.-hydroxyalkyl amide crosslinking agent to a textile, and heating the textile at a sufficient temperature for a sufficient time to react the crosslinking agent with the textile wherein water is removed from the textile, to impart permanent press properties to the textile. The crosslinking agent is free of formaldehyde. The method of the present invention provides permanent press properties to textiles treated therewith and increases the resistance of such textiles to future laundering abrasion. Such treated textiles display a significant reduction in wrinkles compared with nontreated textiles. Moreover, the treated textiles have a tactile sensation of feeling soft and retain their smoothness after laundering.

Title: Artificial implant intended to replace the human urinary and excretory organs
Inventor: LE DUC ALAIN
IPC: A61F2/04
Filed: 1998-02-04
Abstract: The object of the invention is an implant not requiring major surgery for its insertion or for the partial replacement of any of its elements; said prosthesis can be applied for long-term placement. The implant disclosed replaces the entire urinary organs, thereby precluding any possible anastomosis, said implant comprising a double-layered (7, 8) structure for the artificial replacing elements: tubular elements (1, 3) for the renal ducts and urethra, a reservoir (2) for the bladder, and an artificial urethral sphincter (4). The aritificial tubular elements of renal ducts (1) are connected to the reservoir (2) by mechanical attachments (5), said elements (1 to 3) being constituted and formed so that they can pass from a flattened state when empty to an expanded state. The two layers (7, 8) join to form the tubular elements (1, 3), forming respectively an external shell which is sufficiently flexible to submit to deformation by manual pressure, and an internal pocket, which is supple and extractable from the shell, constituting the reservoir (2). This structure allows for the partial replacement of each of its elements and ensures the long-term placement of the prosthesis.

Inventor: FUNCK THEODOR
IPC: F04B53/22
Filed: 1998-03-13
Abstract: The invention concerns a high-pressure pump for pressure measurements, said pump having a modular construction. The drive motor and spindle form a unit connected by a reduction gear. In the pressure-less state, the spindle driving the pump piston is detachably connected to said piston via a universal joint. The piston itself is part of a pump unit which can be connected to a frame via two blocks which are mounted on the frame support and each comprise a U-shaped recess. The advantage of the invention therefore lies in the interchangeability of the entire pump unit and the use for pump units with pressure cylinders for different volumes so that a larger range of pressure measurements can be covered.

Title: Clip with sliding lid for an automotive seat and similar applications
Inventor: MEYER CHARLES
IPC: F16L3/08
Filed: 1999-09-27
Abstract: The clip includes a body and a lid slidably mounted on tracks on the sides of the lid. A trough formed in the body receives a cylindrical item, such as a rod, pipe or conduit. The lid slides between an open or pre-driven position wherein the lid does not cover the trough, and a closed position wherein the lid covers the trough. The tracks are somewhat inclined with respect to the body so that the lid does not contact the rod in the trough until immediately prior to the closing of the lid. Sloped stop ramps on the body detent engage apertures in the lid in both the open position and the closed position. The underside of the body includes a second trough with a "rabbit ear" detent mechanism to engage a second cylindrical item, such as a rod, pipe or conduit.

Title: Controllable delays in multiple synchronized signals for reduced electromagnetic interference at peak frequencies
Inventor: KIM GYUDONG
IPC: H04L25/08
Filed: 1998-09-04
Abstract: Multiple controllable delays reduce EMI radiated during the transmission of multiple synchronized signals. Each controllable delay introduces a controlled delay into a corresponding signal being transmitted. The controlled delay is such that the combined strength of the multiple signals at peak frequencies is substantially reduced. This results in reduced EMI radiation at those peak frequencies.

Title: Bras de levier destine a un microscope a balayage

IPC: G01D5/18
Filed: 1998-09-10
Abstract: L'invention concerne un procédé de production d'un bras levier doté d'une pointe et destiné à un microscope à balayage. L'invention concerne également un tel bras de levier. Pour la production d'un tel bras levier, on peut implanter une résistance piézorésitive dans une tranche présentant une pointe au moyen d'un CMOS. Ensuite, on applique sur la tranche une couche métallique qui recouvre la pointe si la pointe doit être protégée à l'étape suivante ou si une photolaque risque d'être entièrement endommagée par la suite. Contrairement à l'état de la technique, le bras de levier et la pointe sont conçus d'une seule pièce. Le bras de levier comporte, sous une couche d'oxyde, une résistance piézorésistive. Malgré le procédé CMOS, la pointe ne doit avantageusement pas être collée ultérieurement à la main comme c'est le cas selon l'état de la technique.

Patent CA-2304658-A1 (CA)
Inventor: DENT PAUL WILKINSON
IPC: H04B17/00
Filed: 1998-09-23
Abstract: A signal strength for received signal such as a radio signal transmitted over a wireless network is determined based on a large number of sample measurements of the received signal which may be taken over disjoint time intervals. Each sample is digitized so as to take on one of a discrete number of values, for example, 256 possible values for an 8-bit converter. The number of occurences for each of the values is accumulated in bins (counters) and the indication of signal strength is determined by a summation of the measured values based on processing of the counts rather than the sample measurements themselves. The signal strength measurements are provided as monotonically related values, more particularly, logarithmic magnitude representations of the measured signal strength of each sample measurement. Bin counts are reduced iteratively by replacing counts greater than 1 by incrementing the count of a proportionately higher value bin until only counts of 1 or zero remain. These counts are then combined to provide only a single counter with a non-zero count value which indicates the accumulated signal strength of the signal strength measurements. The invention may further be provided using single bit memory elements and byte processing with look-up tables to provide even more efficient processing of the logarithmic signal strength measurements to reduce power consumption for battery powered devices such as cellular radiotelephones.
