Patent CA-2160352-C (CA)
Inventor: MCEWAN THOMAS E
IPC: G01S13/18
Filed: 1994-04-08
Granted: 2006-01-10
Abstract: A motion sensor is based on ultra-wideband (UWB) radar.      UWB radar range is determined by a pulse-echo interval. For motion detection, the sensors operate by staring at a fixed ranged and then sensing any change in the averaged radar reflectivity at that range. A sampling gate is opened at a fixed delay after the emission of a transmit pulse. The resultant sampling gate output is averaged over repeated pulses. Changes in the averaged sampling gate output represent changes in the radar reflectivity at a particular range, and thus motion.

Title: Lateral illumination fiber optic cable device and method of manufacture
Inventor: KINGSTONE BRETT M
IPC: B29C48/10
Filed: 1994-05-20
Granted: 1999-06-29
Abstract: A fiber optic cable (10) suitable for lateral illu-mination lighting installations has a tubular central core (12), wrapped perimetrically with angularly evenly dis-tributed bundles (15) of optical fibers (16) and covered with a transparent sheath (17).  The core includes an outer cylindrical surface (14) of reflective material (24) that deflects inwardly directed lateral emissions back outwardly, so they can contribute usefully to the visi-ble light.  In manufacture, the bundles are wound about the core by a cabling machine which simultaneously extrudes the sheath about the winding. In a modified embodiment, a cable (10') includes an arcuate cutout (30) that mates with a complementary track (39, 40) of a mounting strip (35). Strip (35) includes a reflective substance in an area (38) between upper and lower ca-bles (10') to present a continuous, top to bottom lateral illumination effect.  In another form of the modified em-bodiment, the fiber bundles are provided directly within upper and lower reflective channels (41) formed inte-grally within the mounting strip.

Title: Raman fibre laser, bragg fibre-optical grating and method for changing the refraction index in germanium silicate glass
Inventor: PROKHOROV ALEXANDR MIKHAILOVIC
IPC: C03C25/6208
Filed: 1996-07-05
Granted: 2002-02-12
Abstract: The invention pertains to laser technology, fibre optics and integrated optics and has industrial applicability in the field of fibre-optical and waveguide elements made from germano-silicate glass, in particular in fibre-optical Bragg and long-period gratings, dispersion compensators, integrated optical waveguides and so forth. The invention solves the problem of simplifying Raman fibre-optical lasers operating at wavelengths of 1.24 µm and 1.48 µm and enhancing the efficiency of the radiation conversion associated with Raman scattering. The 1.24 µm laser comprises a pumping source (1), a fibre-optical waveguide (2) containing 1-30 Mol % P2O5; sections of the fibre-optical waveguide containing 11-39 Mol % GeO2 form Bragg fibre-optical gratings (3, 4). The grating (3) forms an opaque dispersion mirror of an optical resonator for a first Stokes component, while the grating (4) is an output dispersion mirror for the same resonator; the first Stokes component issues at the output. In the 1.48 µm Raman fibre-optical laser, the second Stokes component issues at the output. The refractive index in the section of fibre-optical waveguide (11) is altered by directing 270-390 nm laser radiation (12) onto the section, said radiation passing through the protective polymer sheath of the fibre-optical waveguide (11).

Title: Rotary valve for power steering gear

Granted: 2004-07-27
Abstract: A rotary valve for a hydraulic power steering gear, has a sleeve (11) with slots (19a-b) journalled to an input-shaft (10) with grooves ( 18a-c), the co-acting sleeve slots and input-shaft grooves defining axially extending orifices. The orifices are ported as a network such that they form primary and secondary hydraulic Wheatstone bridges arranged in parallel, each bridge comprising two limbs each of which incorporate inlet and return orifices communicating to respective inlet and return ports of the valve. The limbs of the primary bridge incorporate means providing hydraulic communication to one of the cylinder port, whereas the limbs of the secondary bridge do not incorporate such means. The return orifice (34a, 34b) in each secondary bridge limb is formed by a metering edge contour on the edge of a secondary return groove (18c) and circumferentially overlapping an adjacent sleeve bore land when the valve is in its neutral position to such an extent such that the return orifice provides a restriction to hydraulic flow for all valve operating angles thereby applying a back pressure to the upstream inlet orifice. The back pressure being sufficient to significantly suppress the generation of cavitation noise in the inlet orifice.

Abstract: Des accessoires destinés à une meuleuse d'angle comprennent un disque abrasif rotatif jetable, qui présente d'importantes ouvertures de ventilation et d'observation aux formes particulières, destinées à l'emploi avec une plaque-support élastique, elle aussi pourvue d'ouvertures de ventilation aux formes déterminées. Les ouvertures d'une de ces pièces, ou des deux, ont des formes telles que cela réduise au minimum leur accrochage sur les saillies de la pièce et facilite le passage de l'air à travers cette surface. Ce courant d'air aide à refroidir la pièce et les débris éjectés, ce qui réduit l'encrassement. Les ouvertures de ventilation facilitent aussi l'observation de la pièce à meuler, à travers le disque en rotation, durant l'opération de meulage, de telle sorte que l'information de l'opérateur est immédiate. De plus, les trous confèrent davantage d'élasticité au disque, ce dont il résulte que c'est une surface plus grande qui vient au contact de la pièce et que le disque s'use d'une façon plus régulière.

Filed: 1997-05-09
Granted: 2004-01-06
Abstract: An electronic article surveillance system (100) includes a signal generator (22, 24, 26) for generating an interrogation signal (28) in an interrogation zone (30), an antenna (36) which receives a signal (34) present in the interrogation zone (30), and circuitry for cancelling interference. A hybrid interference component cancelling loop forms a digital interference estimate signal (108) which is converted (106) into an analog estimate signal, which is subtracted (102) from an input analog signal (40). The difference signal is digitized and subjected to additional digital interference cancellation processes (108). Each of the signal processing operations (108) entails performing a polyphase decomposition of a digital input signal, estimating a mean value of each of the resulting subsequences, and combining the estimated mean values to form an interference component estimate signal. An input sample window for a comb-filtering stage is phase adjusted relative to the interrogation signal to compensate for changes in phase of the marker signal (34).
