Patent CA-2287533-A1 (CA)
Title: Urine collection device
Inventor: CAWOOD CHARLES DAVID
IPC: A61F5/44
Filed: 1999-10-27
Abstract: A flat urinary drainage bag that can be worn by a patient over the abdomen with the bag suspended from a waist-encircling belt is disclosed. The device includes an inlet tube for connection to a urethral catheter and a valve-equipped drain tube that extends downwardly from the bag when the drain tube is used to drain the contents therefrom. The lower end of the bag is foldable upwardly to position the drain tube in an upwardly-facing raised position against the bag's front wall, and a retaining strap is located across the front wall for holding the drain tube in its raised position. Spot attachments that secure the ends of the strap to the bag's front wall also secure the front and rear walls of the bag together, thereby performing multiple functions of limiting bulging of the bag in use, reducing sloshing of the bag's contents, and securing the retaining strap (and the raised drainage tube) in place.

Abstract: A method of controlling a controllable force generator within a controllable suspension system interconnected between a first member M1 and a second member M2. The method includes the steps of obtaining a first signal (V abs) representative of the absolute velocity of the first member M1, obtaining a second signal (V  rel) representative of the relative velocity between the first and second members, and setting a desired damping force for the generator based upon a control policy which defines a control surface. The control policy includes a preselected gain, an absolute velocity, and a shaping function of relative velocity wherein said control surface exhibits only continuous first derivatives for V rel * V abs > 0 and wherein the control surface is devoid of any surface discontinuities. This control policy effectively eliminates the jerkiness in certain prior art control methods, such as skyhook.

Abstract: La présente invention concerne des moulages de précision, tels que des étriers de frein et d'autres pièces requérant une finition fine et présentant une géométrie interne complexe, qui peuvent être obtenus en moulant par injection un alliage métallique thixotrope, semi-solide, autour d'un noyau (12), de préférence, un noyau moulé sous pression dans une chambre chaude. La chambre chaude possède un point de fusion inférieur à celui de la température de transition qui permet à l'alliage thixotrope de passer de l'état semi-solide à l'état solide. Une fois que l'injection se solidifie de façon à former un moulage (10) à noyau capturé (12), ledit noyau (12) est fondu à partir du moulage (10) dans un bain liquide, dans un four à gaz ou à air, ou au cours d'un traitement thermique de la pièce. Ce procédé réduit considérablement ou élimine les exigences d'usinage pour les parties métalliques coulées du fait que la surface intérieure du moulage (10) est extrêmement lisse et correspond à des exigences de tolérance rigoureuses et du fait que le noyau (12) complètement fondu peut être formé de saillies qui empêchent l'élimination mécanique du noyau (12) du moulage et forme des contre-dépouille, des filetages et des trous, etc. dans le moulage.

Title: Low back haul reactivation delay for high-speed packet data services in cdma systems
Inventor: VITEBSKY STANLEY
IPC: H04B7/005
Filed: 2000-06-09
Abstract: A back haul architecture effectively reduces the reactivation times for both forward-link and reverse-link data transmissions over CDMA wireless communications systems, by relying on packet-mode transmissions over the back haul between a frame selection/distribution (FSD) function and the appropriate base stations for both forward-link data and reverse-link data. In particular, for the forward direction, the FSD function transmits forward-link data only to one base station (i.e., the primary base station), which is solely responsible for controlling the forward-link air interface with the corresponding mobile unit. As such, the forward link always operates in simplex mode for data transmissions, independent of how many base stations are operating in soft handoff for the reverse link with the same mobile unit. For the reverse direction, each base station that receives frames of reverse-link data from the mobile unit, assigns a time tag to the frame, divides the frame into one or more data packets, assigns a different sequence number to each data packet, and transmits the data packets to the FSD function over the back haul, all without first synchronizing time with any other base station that is also operating in reverse-link soft hand-off with that mobile unit. The FSD function (or preferably the radio link protocol (RLP) function) is then responsible for selecting packets of reverse-link data for subsequent processing (e.g., transmission to the network end of the connection). By limiting forward-link data transmissions to simplex mode and using packet-mode transmissions for reverse-link data, the need to first synchronize timing between the various base stations is eliminated for both forward-link and reverse-link data transmissions. As a result, reactivation delays are greatly reduced.

Title: Ultrasonic spectroscopy apparatus and method for determining thickness and other properties of multilayer structures
Inventor: CHOQUET MARC
IPC: G01N29/44
Filed: 2000-07-21
Abstract: An ultrasonic apparatus and method based on location of resonance frequencies, is provided for determining unknown parameters in a multilayer structure, such as thickness, elastic properties of individual layers, or bonding strength between layers. Ultrasonic waves reflected from the front and back surfaces of a thin-layered medium (.notlessthan. 2 mm) overlap and interfere in the time domain. A spectroscopic approach is proposed, collecting and analyzing a large number of echoes together in the frequency domain to measure resonance frequencies and determine properties of the layered medium.  With the presence of a fluid between layers, the resonance modes are mainly those of individual layers in vacuum and an inversion algorithm has been successfully applied to recover some properties. For adhesively bonded layers, the resonance modes of the individual layers are strongly coupled and important frequency shifts are observed. A characteristic equation which includes a bonding parameter can be derived for a given type of multilayer structure and a numerical inversion technique is used to obtain thicknesses or other properties from measured resonance frequencies. The method is of particular interest when ultrasound is generated by a laser and detected by either a contact ultrasonic transducer or a laser interferometer.
