Title: Receiver calibration technique for global orbiting navigation satellite system (glonass)
Inventor: BALODIS MIROSLAW
IPC: G01S1/00
Filed: 2000-02-07
Granted: 2008-04-22
Abstract: A GLONASS receiver and a corresponding method for its calibration for more precise carrier phase measurements. The receiver includes a conventional receiver channel (36), having a bandpass filter (40) for establishing the sampling bandwidth prior to digitizing a plurality of received satellite signals, each having a different frequency. The receiver also includes a calibration channel (50) in which multiple satellite signals are bandbass filtered (in filter 58) at a single intermediate frequency, to avoid errors resulting from group delay variation introduced by passing multiple satellite signals through a common bandpass filter. The calibration channel (50) downconverts (56) to the intermediate frequency, bandpass filters (58), and then upconverts (60) again. Each satellite signal in turn is processed in this manner by selecting appropriate difference frequencies for downconversion and upconversion. The calibration channel (50) produces a set of reference carrier phase measurements that can be applied to correct errors in carrier phase measurements generated by the conventional receiver channels (36).

Title: Method and system for global communications network management and display of market-price information
Inventor: MASHINSKY ALEXANDER
IPC: H04Q3/00

Granted: 2005-06-21
Abstract: A system and method for flexibly routing communications transmissions in an efficient manner is disclosed. Service providers connecting to international gateway switches (22-28) for submitting information to a centralized server (56) which comprises cost and service parameter data for routing a communication from a first location (2) to a second location (4). The server node receives all of the submitted rate information, evaluates it, and generates from the information a rate-table database comprising efficient routing paths for connecting transmissions between any two locations in a communication switching network. Service requesters submit service requests to the centralized server node. The server node identifies efficient routes which meet the requester's requirements and brokers sales of communication time from the service providers to the service requesters. The system is also capable of displaying market price information related to the supported communication routes to prospective sellers and buyers of connection time.
Patent CA-2305366-C (CA)

Granted: 2007-10-16
Abstract: Cette invention se rapporte à un procédé et à un appareil permettant de mesurer un analyte dans un tissu d'un sujet. Ce procédé consiste à mettre le tissu en contact avec un rayonnement électromagnétique ayant une première longueur d'onde d'excitation, laquelle est sensiblement égale à une longueur d'onde d'absorption d'une sonde thermique à l'intérieur du tissu en question. La sonde thermique et l'analyte sont suffisamment proches l'un de l'autre pour que l'énergie se déposant dans l'un d'eux par absorption du rayonnement soit transférée à l'autre. Les spectres Raman émis par le tissu sont recueillis et analysés pour déterminer une concentration de l'analyte présent dans le tissu. Cette analyse peut consister à mesurer les spectres Raman associés à la sonde thermique. Ce procédé peut consister en outre à mettre simultanément en contact le tissu avec un rayonnement électromagnétique ayant la première longueur d'onde d'excitation et avec un rayonnement électromagnétique ayant une seconde longueur d'onde d'excitation, laquelle est sensiblement égale à une longueur d'onde d'absorption de l'analyte. Cette analyse consiste à comparer les spectres émis en réponse à la première longueur d'onde d'excitation en présence et en l'absence de la seconde longueur d'onde d'excitation. Dans un autre mode de réalisation, cette analyse consiste à mesurer la composante anti-Stokes des spectres Raman associés à l'analyte. Ce procédé permet ainsi une mesure non invasive du glucose sanguin, au moyen de l'hémoglobine comme sonde thermique.

Abstract: Oriented strand board (10) is produced using a continuous belt press (22) and using an isocyanate binder with steam exposure of the mat (18) of wood material prior to entry into the press. The steam exposure provides moisture which softens wood fibers and enhances lignin flow in the mat. In addition, the moisture reacts with isocyanate binder to produce polyureas from the isocyanate binder (e.g. the preferred binder is pMDI); thereby reducing the cure conditions (i.e.  temperature, pressure and time) required for the press to fuse the mat and binder together. The isocyanate binder also reacts with hydroxyl groups in the cellulose and hemicellulose strands of the wood material to allow both chemical and physical bonds to be created with the wood material. The oriented strand board exiting the press has a higher moisture content and more resistant thickness swell under humid conditions.

Title: Weight distributing hitch assembly
Inventor: HOELSCHER DAVID L
IPC: B60D1/06
Filed: 2000-07-07
Granted: 2005-03-22
Abstract: A weight distributing hitch assembly includes a shank, hitch head, spring bar and lift assembly. The lift assembly is preferably removable mountable to the frame members of a trailer frame while the spring bar extends below the frame members relative to the ground. The lift assembly mounts a hanger assembly which engages a cantilevered segment of the spring bar to drive the spring bar from a free state to a loaded state to distribute the hitch load to a towing vehicle as well as to the trailer. A  lever assembly mounts the hanger assembly to the lift assembly and supplies mechanical advantage to assist a user during tensioning of the spring bar. By moving the lever assembly, the cam rotates about a pivot. As the hanger assembly is engaged with the cam, the hanger assembly is driven from a disengaged position to an engaged position which moves the spring bar from its free state to its loaded state with a minimum of user effort.

Abstract: A priority valve (50) for a compressed air system (10) in a tire retreading plant includes a solenoid controlled, diaphragm operated valve (52) connected at an inlet to an autoclave (40). A solenoid (54) controls whether the valve is opened or closed. A switch (70) has a pressure sensor connected to an inlet side. If the pressure falls below a low pressure limit, the switch (70) activates the solenoid to close the valve, thus shutting off the air supply to the autoclave (40). With the inlet to the autoclave closed, the air compressor (20) is able relatively quickly and easily to raise the pressure in the system above the low pressure limit. The valve (54) remains closed until the sensed pressure rises to a value sufficient to supply both the other equipment (28, 30) and the autoclave.

Abstract: In the field of sound reproduction it is customary to use diaphragms excited by magnetic motors or tape electrostatic systems. All these products have important volumes being actuated to produce sound. Inversely, sound is an impact between air particles which are infinitely small in volume which provide them with high sound propagation velocity. The invention concerns a method using low level electromagnetism which relies on ambient air particles, thereby generating a novel magnetic field. Said method is characterised in that it uses an apparatus consisting of at least an electric wire winding (1) coiled on a flexible polymer support (2), with an impedance of 8 ohms. Said apparatus is coupled with an audio electric signal of an acoustic chamber or an acoustic supply. Said method and apparatus can be used on all audio, audio-visual systems and any communication mode such as telephone, radio as well as in the medical field for the auditory comfort of hard-of-hearing persons.

Abstract: A vehicle system is disclosed that includes a vehicle lamp assembly including a plurality of LEDs that emit white light so as to function as an illuminator light. The lamp assembly also may include a plurality of LEDs that emit colored light, such as red or red-orange, so as to function as a signal light. Alternatively or additionally, the lamp assembly may include a camera of a vehicle imaging system. The lamp assembly may serve as a center high mounted stop light or as a tail light. The system also includes a controller that rapidly pulses the LEDs on and off at a rate that is imperceivable by the human eye. The pulsing intervals of the LEDs may be related to the readout intervals of the camera sensor array. In this manner, the LEDs may be pulsed on during camera readout so as to increase their intensity while the camera is capturing an image, or may be pulsed off during camera readout to prevent feedback glare from interfering with image capture by a highly sensitive image sensor array on the camera.
