Patent CA-2300343-C (CA)
Title: Label switched media gateway and network
Inventor: MAUGER ROY
IPC: H04L45/02
Filed: 2000-03-09
Granted: 2010-05-18
Abstract: A network arrangement for delivering IP services to subscribers comprises a core network, a plurality of label switched media gateways coupled to the network and each providing an interface for one or more subscriber terminals. Call servers associated with the network are used to establish connections between pairs of gateways, these connections being routed across the core network via tunnels established therein. The tunnels are exclusively reserved for traffic between the label switched media gateways so as to provide security of that traffic from third party access and to provide a guaranteed quality of service. Because traffic is accepted into a tunnel only if bandwidth is available in that tunnel, firm and meaningful quality of service guarantees can be given to users.
Patent CA-2300549-C (CA)
Inventor: O'NEAL CHARLES P
IPC: F21V15/00
Filed: 2000-03-07
Granted: 2005-11-15
Abstract: The present invention comprises a mounting bracket that may be permanently mounted to a vehicle, such as by riveting. The mounting bracket includes at least one deflectable tab that is deflected away from a main plane of the bracket when the lamp assembly is pressed against it. The lamp assembly includes an extending surface which interacts with the mounting bracket tab in order to deflect the tab. Subsequent rotation of the lamp assembly in a clockwise direction causes the lamp extending surface to move under the mounting bracket, allowing the deflected tab to return to its quiescent position. Any attempt to remove the lamp assembly from the mounting bracket by turning the lamp assembly in a counter-clockwise direction is prevented by interaction between the lamp extending surface and the now non-deflected mounting bracket tab. Theft of the lamp assembly is thereby prevented.

Title: Skate sharpener
Inventor: WILSON MURRAY DAVID
IPC: B24B3/00
Filed: 2000-05-23
Granted: 2003-07-29
Abstract: A skate sharpening apparatus includes a skate blade holding device, the skate blade sharpening device having a horizontally mounted sharpening wheel which is rotatably driven, and wherein the skate holding device has first and second jaws for contacting opposite sides of a skate blade. First and second pivot arms each having first and second ends with the pivot arms being mounted intermediate the first and second ends are arranged such that the first ends of each of the arms are connected to the first and second jaws respectively. A linearly moveable actuator moves second ends of each of said first and second pivot arms, the linearly moveable actuator causing each of the pivot arms to move an equal distance and therefore move each of the jaws in equal distance, with a center line of the linearly moveable actuator lying in the same plane as a center line extending through a skate blade held between the jaws and a center line extending through the sharpening wheel. The arrangement is such that a perfectly centered sharpening of the skate blade is achieved irregardless of the skate blade width.

Abstract: A variable optical delay line using MEMS devices. A reflector on a micro machine linear rack is positioned and spaced from an input source and/or an output to receive and reflect input light waves toward the output. The distance between the reflector and the input and output is variable and thereby enables selective path delay compensation of the input light wave signals. Other disclosed embodiments utilize pivoting MEMS mirrors and selective adjustment of the mirror pivot angles to provide the selective path delay compensation required in a light wave system.

Title: Hydrogen gas sensor
Inventor: NADANAMI NORIHIKO
IPC: H01M8/04

Granted: 2008-04-08
Abstract: A hydrogen gas sensor capable of accurately measuring hydrogen concentration of a measurement gas atmosphere in the presence of a variety of interfering gasses such as H2O and CO. In the hydrogen gas sensor, the flow sectional area of a diffusion-rate limiting portion 6 is rendered small; the electrode surfaces of first and second electrodes 3 and 4 are rendered large; and/or a solution containing a polymer electrolyte which may be identical to that of a proton-conductive layer 2 is applied onto the surfaces of the first and second electrodes 3 and 4 to thereby form a layer containing the polymer electrolyte. Thus, the rate of conduction of protons from the first electrode 3 to the second electrode 4 becomes greater than the rate at which protons are derived from hydrogen which is introduced onto the first electrode 3 via the diffusion-rate limiting portion 6.

Title: System and method for reducing call dropping rates in a multi-beam communication system
Inventor: MARSH GENE W
IPC: H04W48/08
Filed: 1999-07-21
Granted: 2006-01-24
Abstract: Method for reducing call dropping rates in a multi-beam communication system that includes a user terminal, a gateway, and a plurality of beam sources projecting a plurality of beams, and where a link between the user terminal and the gateway is established on one or more beams. The method relies on a messaging protocol between the gateway and the user. Based on messages sent from the user to the gateway, preferably on a preselected periodic basis, the gateway determines the more desirable beam(s) for transmitting to the user. The messages sent from the user to the gateway contain values representing beam strengths as measured at the user.      The gateway uses the user measured beam strengths to select the beams that should be used for the user. The beams to be used are the beams that will decrease the call dropping rates and provide a desired level of beam source diversity.

Abstract: A method and a device are disclosed for producing an X-ray pixel detector, i.e. an imaging detector for X-ray photons, the detector presenting high efficiency combined with high resolution for obtaining a high image quality detector while at the same time minimizing the X-ray dose used. The application is particularly important whenever the X-ray photon absorption distance is much longer than the required pixel size. The arrangement according to the present invention presents a structure based on light-guiding of secondarily produced photons within a scintillating pixel detector in conjunction with, a CCD or a CMOS pixel detector. The structure according to the invention presents a matrix (8) having deep pores (10) fabricated by high-aspect ratio silicon etching techniques producing very thin walls and with a pore spacing less or equal to the size of a pixel (2) of the image detector used. The pore matrix is subsequently filled by melting a scintillating material into the pores such that, in each pore, a single scintillating block is formed. The silicon matrix (8) may further utilize a reflective layer to increase light guiding down to the image detector chip.

Abstract: An insulation blanket (20) is disclosed that contains fire-blocking material s for preventing rapid penetration of fire into an aircraft fuselage (28) in case of fire outside the aircraft. The insulation blanket (20) contains at least one layer (24) of fiberglass or other thermal-acoustic insulation material without fire-blocking properties, and one or more layers (33) of fire-blocking material. The fire blocking material (33) is wider than the thermal-acoustic insulatio n (24) so that it may be folded against and attached to adjacent structural frame members (31) of the fuselage. In the alternative, a thermal-acoustic insulation material (24) is used that has fire-blocking properties instead of the separate layers of fire-blocking and thermal-acoustic insulation materials. A method for installing insulation blankets according to the present invention is disclosed, whereby a fire-blocking insulation portion of the blanket is folded against and attached to frame members (31) of the aircraft using attachment posts or spring clips.

Abstract: A parking brake control circuit engages the parking brake of a vehicle when the transmission of the vehicle is in the "park" position and the engine of the vehicle is turned off, without requiri ng the constant application of electrical power. The parking brake control circuit utilizes latching solenoid (12) technology that eliminates the need for a constant voltage source. A time-delay relay (16) is used to change the state of the latching solenoid (12). The ti me- delay relay is preferably activated through a circuit containing an engine oil pressure switch (22), a transmission park switch (2 0) and a vehicle speed switch (18). Activation of the relay latches the solenoid in a position that allows the parking brake to be applied, without requiring the application of a constant voltage to the solenoid. Accordingly, the possibility of inadvertent brake application due to electrical failure is avoided.
