Patent CA-2192651-A1 (CA)
Inventor: KALLIN HARALD
IPC: H04W48/20
Filed: 1995-06-27
Abstract: Un réseau téléphonique mobile analogique comporte des cellules à voies de conversation (C1), dont chacune comprend une station de base (A-G). Ces stations de base procurent des voies de commande associées (PAC) pour rechercher une station mobile (MS), et également des voies d'accès (AC) pour établir des connexions à destination ou en provenance de la station mobile (MS). Cette station mobile possède des informations concernant les fréquences de toutes les voies d'accès et les connexions sont établies sur des voies de conversation duplex (TC). La zone géographique couverte par les cellules à voies de conversation (C1) respectives est déterminées par l'utilisation, à des fins communes prédéterminées, de toute les voies de conversation (TC) au sein de cette zone. Chacune des cellules à voies de conversation (C1) dispose d'au moins deux voies d'accès (PAC, AC) espacées d'un intervalle de fréquence souhaité et possédant la même couverture radio que les voies de conversation (TC). Lorsqu'un accès est souhaité, la station mobile (MS) analyse la puissance de toutes les voies d'accès à deux reprises avec un intervalle de 20 millisecondes. Les voies d'accès duplex (PAC, AC) aident la station mobile (MS) à trouver la voie d'accès (PAC, AC) la plus puissante en dépit d'un évanouissement profond. La station mobile (MS) établit ainsi une connexion sur la voie de conversation (TC) dans la cellule (C1) la plus appropriée possédant la plus forte intensité du signal. Des transferts inutiles sont évités et la qualité de transmission téléphonique est améliorée.

Title: Container carrier with different coefficients of friction
Inventor: WEAVER WILLIAM N
IPC: B65B17/02
Filed: 1997-04-04
Abstract: A multi-package carrier device having a strip of a relatively high coefficient of friction material along an inner portion of the carrier. A high coefficient of friction, "tactile," material is applied to an encircling aperture style multi-package carrier device made from a relatively low coefficient of friction thermoplastic base material sheet. A strip of the tactile material is applied along one side of the base material of the multi-package carrier. The base material containing the tactile material is then cut into multi-package carriers such that the tactile material traverses a center portion of a container contacting surface of the multi-package carrier. The multi-package carrier is applied to a plurality of containers. After the multi-package carrier is applied to the containers, the tactile material between the rows of containers is in close contact with an upper portion of the container sidewall. The high coefficient of friction tactile material resists movement of the containers with respect to the carrier.
Patent CA-2204566-A1 (CA)
Title: Apparatus and method for sterilization and embolization
Inventor: RYAN THOMAS P
IPC: A61N7/02
Filed: 1997-05-06
Abstract: An apparatus (20) for transcervical sterilization or transcatheter embolization with a controlled bipolar RF catheter (21) for creating thermal lesions (22) in the fallopian tubes (23) or thrombosing vessels has a catheter (21) elongate along an axis thereof with a patient end (24). The catheter (21) is circular and sized for transcervical insertion into the fallopian tube or transcatheter vessel insertion, respectively. A connector (25) on an end of the catheter (21) opposite the patient end (24) has the terminations (26) for RF and monitoring and is shaped for the surgeon to manipulate during placement and withdrawal. Two or more bipolar electrodes (29, 30 and 31)on the patient end (24) are placed so each electrode is spaced from another with each circumscribing the catheter (21). A mucosa or thrombus sensor responsive to applied RF energy passing between the two or more bipolar electrodes (29, 30 and 31)determines the condition of the transmural formation of a lesion or the thrombus between each of the electrodes. The sensor is a temperature sensor positioned in the space (34) between the electrodes measures the change in mucosal layer temperature or the thrombus during the application of RF energy. An RF generator (27) electrically coupled to the electrodes and the sensor is alternately a phase detector (35) in circuit with the coupling determines reactance of tissue as an indicator of lag or lead of the voltage wave form or current wave form delivered or is an impedance responsive circuit (39) positioned in the RF generator (27) to determine voltage and current delivered so a calculator finds impedance delivered for finding initial electrode contact with the tissue and for measuring the change in mucosal layer. A blunt tip at the patient end (24) facilitates introduction into the tube or vessel to avoid perforation. The temperature sensor connects to an RF generator (27) with control circuitry regulating delivery to a temperature range. A proportional controller regulates the RF energy delivery to control temperature rise time and to maintain the temperature near the mid point of the temperature range. A method for sterilization has the steps of inserting a catheter (21), delivering RF and monitoring the effect on the mucosa or thrombus, circumscribing the catheter (21) with two or more bipolar electrodes, each of the electrodes spaced from one another and passing RF energy therebetween.

Title: Offset detection apparatus and flying object guiding system using the apparatus
Inventor: HOSAKA NAOKI
IPC: F41G7/26
Filed: 1997-09-29
Abstract: A light wave guiding apparatus comprising an offset detector for detecting an offset from a predetermined axis is disclosed. A laser beam irradiator irradiates a laser beam having a maximum irradiation intensity in a predetermined orientation and the irradiation intensity decreasing progressively with the increase in the distance away from the orientation while being conically inclined from a predetermined axis.

Title: Fluidly expandable urethral plug assembly which receives fluid from an external source and method for controlling urinary incontinence
Inventor: WISNOSKY CARL J
IPC: A61M31/00
Filed: 1996-04-30
Abstract: This invention is a novel urethral plug (I) comprising a cooperating shaft (12) and balloon (18), lying in coaxial engagement. The balloon (18) possesses a contracted shape for insertion and removal through the opening of the urethra. and a larger, expanded shape for blocking the flow of urine in the urethra, bladder neck, and bladder. After inse rtion such an expanded shape is achieved by inflation of the balloon (18) through the use of an external source such as a syringe which intro duces fluid through an opening and into the shaft. The fluid acts upon a ball valve (22), thus pushing the ball past a valve seat, thereby pe rmitting fluid to travel through the shaft and into the balloon (18). Fluid transmission continues until the balloon (18) is expanded to such an extent as to block the flow of urine.
