Patent CA-2311013-A1 (CA)
Title: Deployment of dual reflector systems
Inventor: NGUYEN STEPHEN D
IPC: H01Q3/20
Filed: 2000-06-08
Abstract: A method and system for deploying a multi-reflector antenna system (10). The antenna system (10) includes an antenna structure (12) mounted to a satellite (14), where an antenna feed array (16) is mounted to the antenna structure (12). A  single articulated antenna arm assembly (26) is mounted to the antenna structure (12) by a first spring loaded hinge (28). The arm assembly (26) includes a first arm (30) on which is mounted a first reflector (38), and a second arm (32) on which is mounted a second reflector (40). The first and second arms (30, 32) are connected to each other by a second spring loaded hinge (34) such that the reflectors (38, 40) directly oppose each other and are substantially parallel when the arm assembly (26) is in the stowed position. A plurality of launch locks (44, 46, 50, 54) hold the arm assembly (26) in the stowed position against the bias of the hinges (28, 34) prior to deployment. When the antenna system (10) is ready to be deployed, the launch locks (44, 46, 50, 54) are released in a predetermined sequence such that the arm assembly (26) first moves away from the feed array (16) under the bias of the first hinge (28), and then the second arm (32) moves away from the first arm (30) under the bias of the second hinge (34). When the antenna system (10) is in the fully deployed state, the feed array (16) and the first and second reflectors (38, 40) are oriented relative to each other to define a side-fed geometry.

Inventor: ANGMAN PER G
IPC: E21B23/02
Filed: 2000-06-09
Abstract: A cement float collar is disclosed that can be positioned downhole and used in a wellbore completion operation after drilling a wellbore with casing. A wellbore drilling and completion method is also disclosed. The cement float collar is made for pumping downhole and into engagement with a groove formed in the casing, called the profile nipple. As such, no restriction is needed in the casing for accepting or latching the float collar and the portion of casing including the groove can be installed at the start of the drilling operation. In addition, the profile nipple can be used to engage other drilling tools and, therefore, can already be in place when the final well depth (TD) is reached.

Patent CA-2314423-A1 (CA)
Inventor: MIYAZONO KOHEI
IPC: A61K38/18
Filed: 1998-11-30
Abstract: L'invention concerne des compositions et des procédés servant à entretenir l'intégrité de muscles lisses, en particulier de muscles lisses vasculaires. Les maladies vasculaires sont caractérisées par une accumulation excessive de cellules de muscles lisses vasculaires qui a pour conséquence l'occlusion d'un vaisseau sanguin, et/ou par une perte d'élasticité des vaisseaux sanguins. Des causes d'occlusion de vaisseaux sanguins comprennent notamment une prolifération de cellules de muscles lisses et des réactions inflammatoires. Une inhibition de la prolifération de cellules de muscles lisses ou de réactions inflammatoires constitue un traitement efficace de troubles vasculaires tels que l'athérosclérose et la resténose. Le traitement peut comporter l'administration d'une protéine morphogénique. La protéine elle-même peut être administrée au site d'occlusion vasculaire, ou peut être administrée par un vecteur, tel qu'un vecteur adénoviral contenant un insert d'ADN codant pour une protéine morphogénique. Ces compositions et procédés peuvent également inhiber les réactions de cellules de muscles lisses à divers traumatismes, telle qu'une exposition à des agents toxiques. Tous ces traitements servent à préserver le phénotype de la cellule par l'inhibition d'une augmentation de protéines de matrice extracellulaire, tel le collagène, ou par l'entretien de l'équilibre normal de protéines de matrice extracellulaire, tels les collagènes de type I et III.

Patent CA-2319030-A1 (CA)
Inventor: HARDMAN GORDON EDWARD
IPC: H04B1/38
Filed: 1999-02-02
Abstract: An interrogation system for enabling transmission and/or reception of RF  signals by a communication system. In accordance with the present invention, an interrogation is performed between a transceiver and an antenna prior to the transceiver transmitting or receiving RF signals via the antenna. The interrogation is used to determine whether the antenna transmits and/or receives RF signals having the power and/or frequency band required by the transceiver. The interrogation is performed by an interrogating device transmitting an interrogation signal to the other, responding device. The responding device transmits a response signal to the interrogating device in response to receiving the interrogation signal. The interrogating device determines if the response signal has a predetermined characteristic. If the response signal has the predetermined characteristic, transmission and/or reception of RF signals is enabled. An alternative use of the interrogation is to identify which one of a plurality of antennas connected to the transceiver is to be used to transmit or receive RF signals.
Patent CA-2319787-A1 (CA)
Title: Antitheft interrupt system for vehicle starter or solenoid circuit
Inventor: LABELLE JAMES L
IPC: B60R25/04
Filed: 1999-02-01
Abstract: A vehicle antitheft system includes a MOSFET (418) with associated power and logic circuitry that can be housed within a starter solenoid housing (704) for preventing control current from activating the solenoid unless an authorized enable signal is received. The enable signal can be transmitted by a hand-held rf transmitter. In alternate embodiments, the MOSFET can be disposed in a housing separate from the solenoid and mounted near the solenoid, and the MOSFET can be controlled by an rf-generated enable signal or by an impulsegenerated enable signal. In the latter case, the MOSFET is activated to close the solenoid control current circuit path only when a single impulse signal, e.g., from a door latch lock, is activated. If two impulse signals are received, one from, e.g., the door latch lock and another from, e.g., a locking mechanism/switch inside the vehicle, the MOSFET is not activated, to prevent a thief from actuating the system by breaking into the vehicle and unlocking the vehicle door from inside the vehicle.

Abstract: An apparatus for delivering energy to a biological site includes an electrode device having a plurality of electrodes, the electrode device positioned proximal the biological site. A power control system supplies power having a controllable phase angle to each of the electrodes. A backplate is also positioned proximal the biological site so that the biological site is interposed between the electrode device and the backplate. The backplate is maintained at the reference voltage level in relation to the power. The power control system controls the phase angle of the power so that the current flow between the electrodes and between the electrodes and the backplate results in the continuity and depth of lesions desired. In a preferred embodiment, the electrodes are arranged in a substantially linear array.
Patent CA-2328844-A1 (CA)
Inventor: THIELER STEPHEN M
IPC: H04M3/00
Filed: 2000-12-19
Abstract: In a wireless switching system in which base stations dynamically re-arrange logical coverage areas, when a base station enters a new logical coverage area, wireless handsets registered on the base station do not have to report individually this change in logical coverage areas to a wireless switching system controlling the wireless switching system. The base station performing the transfer from one logical coverage area to another logical coverage area informs the wireless switching system controller of the change in logical coverage areas both for the base station itself and for each of the wireless handsets registered on the base station. The base station informs the wireless handsets that the logical coverage area is being changed and informs the wireless handsets that they do not have to re-register. This reporting by the base station greatly reduces the number of operations performed when the base station moves from one logical coverage area to another logical coverage area.
