Patent CA-2313485-A1 (CA)
Title: Method and system for determining position of a mobile transmitter
Inventor: KOORAPATY HAVISH
IPC: G01S5/06
Filed: 1998-11-20
Abstract: A system and method is provided for determining position of a mobile transmitter, such as a cellular telephone. The transmitter transmits a first signal at a first frequency (such as a RACH signal) to first and second receiving stations. The receiving sites are located at known locations. The transmitter then transmits a second signal at a second frequency (such a traffic signal) to the first and second receiving stations. The phases of the first and second signals at the first and second receiving sites are measured.  Using the measured phases and the first and second frequency values, a range difference is calculated. This range difference defines a first hyperbola having the first and second receiving stations as foci on which the transmitter is located. By repeating the procedure with a different pair of receiving sites, a second hyperbola can be determined. The intersection of the first and second hyperbolas define the position of the transmitter.
Patent CA-2317784-A1 (CA)
Inventor: MOSSBERG THOMAS W
IPC: G02B6/34
Filed: 1999-01-07
Abstract: La présente invention porte sur une structure de grille optique qui effectue une fonction programmée de filtrage spectral complexe sur un signal optique d'entrée. La grille comprend une pluralité de sous-grilles. Chaque sous-grille guide la diffraction d'une sous-largeur de bande optique spécifique de lumière, d'un sens d'introduction fonctionnel à un sens d'émission fonctionnel conférant une amplitude et une variation de phase contrôlables sur la sous-largeur de bande spécifique de lumière que la diffraction régule dans la largeur de bande fonctionnelle globale. Chaque grille composite est programmée par sa structure ou sa modification dynamique de façon à obtenir des fonctions de filtrage spectral spécifiques. Tandis que les grilles composites peuvent être utilisées dans des applications générales de filtrage spectral, elles conservent un potentiel spécifiquement attractif dans la zone de traitement, génération et détection de formes d'ondes.
Patent CA-2319880-A1 (CA)
Title: Laser beam adjustment
Inventor: HOLLANDER MILTON BERNARD
IPC: G02B23/04
Filed: 2000-09-15
Abstract: The invention relates to instruments, such as radiometers, which generate a laser beam for striking a target at a distance to assist in aiming the instrument at a selected area of a target. Provision is made for splitting a single beam, used for instance for centering the instrument on the target, into a plurality of beams for creating a pattern or for defining an area on the target, When a single beam is split, the resultant plural beams produced are of relatively lower power, which may be insufficient for visibility on a target at a distance. In a first embodiment the invention provides apparatus to increase the power of the single laser beam when it is spilt, so as to provide plural beams of appropriately higher power and visibility. In a second embodiment, the invention provides apparatus for attenuating the beam power when a single beam is used, and for removing the attenuation when the beam is split into multiple beams. Apparatus for changing the single beam of the instrument to multiple beams, and vice versa, has a body structure with a relatively movable carrier incorporating a beam splitter device, and an attenuating or non-attenuating device, such that relative movement of the carrier causes, in a first embodiment, an increase of the laser beam power when only a single beam is used, and in a second embodiment an attenuation of the laser beam power when a relatively higher power single beam is used. In the second embodiment, the relative movement of the carrier serves to actuate switching means controlling the power of the laser beam.  Such apparatus is advantageously in the form of an attachment for engagement releasably on the laser beam instrument.

Abstract: A rotary union assembly for use in an automatic tire inflation system for maintaining the desired pressure in the tires on a tractor trailer or other vehicle having pressurized axles. The assembly communicates the valve stems on a pair of adjacent tires with the axle interior through the use of a flexible tube extending between a stationary first fitting threadably engaged in the axle spindle and a rotary housing (50) secured against the outside end surface of the hub cap (54) so as to be positioned exteriorly of the wheel lubrication compartment and rotatable with the hub cap (54). The first fitting defines an open channel (58) extending axially therethrough and includes an o-ring (43) seal extending about the channel (58) and forming an airtight seal within the fitting about the tube. A  stationary shaft member having an air passageway extending axially therethrough carries the downstream end of the flexible tube and projects into the rotatable housing (50) to communicate the axle interior with the housing through the flexible tube and provide a rotatable mounting for the housing on the shaft. The shaft defines a stationary bearing surface on its downstream end. A rotary sealing member having an air passageway extending axially therethrough is mounted within the housing for rotation therewith. The rotary sealing member defines a rotary bearing surface which is urged the stationary bearing surface on the shaft member by a spring member. Opposed channels are provided in the housing proximate the bearing surfaces and hose and valve assemblies communicate the opposed channels with the tire valve stems.

Title: Knuckle drive link conveyor belt systems
Inventor: STEEBER DORIAN F
IPC: B65G17/38
Filed: 1999-10-28
Abstract: This invention provides integrated knuckle drive link conveyor belt systems with improved long wear-high load bearing link coupling joints of a universal joint nature for permitting the belts to travel on straight or curvaceous paths which also feature expedited insertion of spindle rods extending through the knuckles, diverse sprocket drive capabilities and replaceable load conveying platform accessories of the plug-in or snap-in variety.      A cylindrical knuckle, when the loaded belt is under tension, has a substantially semi-cylindrical high wear contact surface that handles heavy peak loads. That knuckle is installed expeditiously at a joint between end-to-end connected links consisting a special interfitted jig comprising a seat in the nose end of a link resting the knuckle in a registered operational position to receive the connecting spindle rod through trailing edge bifurcated arms of a leading modular link without a concurrent manual orientation of the knuckle. Diverse sprocket drive structure permits the belt to be driven from beneath or on either lateral side. The knuckle and surrounding seat provides three dimensional moving tolerances to provide the universal joint type operation at each link joint. Other features include side rollers to reduce friction on inner curve radii, and hold down flanges that keep the belt from fluttering off a base support surface. The rugged molded resulting plastic links are long wearing and resist catastrophic failure. The versatility and ruggedness of the system is significantly enhanced by the removable platform structure for heavy industrial use.
