Patent CA-2225638-A1 (CA)
Inventor: CHRIST ROGER
IPC: G01S19/48
Filed: 1998-02-06
Abstract: To locate a person within a particular room inside a building or, if outside, within a small enough radius that enables a rapid identification of where that person is located, a system of sensors is strategically disposed throughout the building or area. The sensors are calibrated so that upon activation of an alarm the feedback from all of the sensors enables differentiation of the location of the alarm. To locate an object within a defined area, received values output by the sensors are compared to stored reference values received by the sensors when transmitting reference signals. A best fit of the received values against the reference values is performed to determine the location of the person. To create the stored reference values, a calibration of the sensors is performed. This includes transmitting one at a time a plurality of reference signal levels, and measuring an output of each of the sensors after each transmission. One particularly noteworthy aspect of the present invention is that the sensors are coupled to a central computer via AC power lines in the facility in which the person is to be located. In this case, the AC power lines act as the physical interconnection layer of a local area network.

Title: Crosstalk-reduced integrated digital optical switch
Inventor: KOREN UZIEL
IPC: G02F1/015
Filed: 1998-01-19
Abstract: Methods and apparatus for performing optical signal switching or other optical routing functions in an optical device or system, in which crosstalk induced by modal interference is suppressed by providing appropriate loss, gain and/or refractive index changes in different parts of a switch structure. An exemplary optical signal switch includes first and second branches each having a refraction-controlled section and an absorption-controlled section. An optical signal path over which an optical signal propagates in passing through the switch is selected to include a portion of at least one of the first and second branches, such that one of the first and second branches is a selected branch and the other branch is a non-selected branch. The refraction-controlled section of the selected branch is configured in a high effective refractive index state which allows the optical signal to propagate along at least a portion of the selected branch, while the refraction-controlled section of the non-selected branch is configured in a low effective refractive index state. The absorption-controlled section of the selected branch is configured in a low absorption state, while the absorption-controlled section of the non-selected branch is configured in a high absorption state to reduce crosstalk within the optical switch. An effective refractive index in a given refraction-controlled section may be provided using electro-refractive techniques such as the quantum-confined Stark effect (QCSE) or the Franz-Keldysh effect, or by carrier-induced effects such as carrier injection or carrier depletion. An absorption change in a given absorption-controlled section may be provided using electro-absorptive techniques or a gain-switching technique. The switch may be configured as a Y-branch switch, a directional coupler, or in other suitable configurations, and may be interconnected with other similar switches to construct 1xN, Nx1, NxM and NxN  switch arrays.

Patent CA-2229669-A1 (CA)
Title: Bearing seal with uniform fluid purge
Inventor: HOETING STEPHEN C
IPC: F16C33/76
Filed: 1998-02-16
Abstract: A bearing seal includes a bearing housing which houses a rotatable shaft, with a flange of the shaft located outside the housing and an internal annular volume residing between the bearing housing and the shaft, the annular volume bounded at one axial end by the flange.  A seal resides in a recess in an outer surface of the housing, the seal including an outwardly extending resilient lip which engages the flange to close off the annular volume at the first axial end, adjacent the flange.  The bearing housing includes a fluid passage which extends from an outer surface thereof to the annular volume, the passage including an innermost section oriented tangential to the annular volume.  Purge fluid supplied to the annular volume via the external passage causes circumferential flow and substantially radially uniform purge fluid pressure within the annular volume.  Build up of the purge fluid pressure in the annular volume eventually causes the lip to flex away from the flange to cause substantially uniform outward flow of purge fluid around the periphery of the seal, thereby to prevent ingress of contaminants.
Patent CA-2229774-A1 (CA)
Inventor: CROWLEY JOSEPH M
IPC: G09F9/37
Filed: 1997-06-25
Abstract: A gyricon or twisting-particle display based on spheroidal optically anisotropic particles disposed in a substrate. The particles are preferably aligned parallel to one another and packed close together in a monolayer. A rotatable disposition of each particle is achievable while the particle is thus disposed in the substrate; for example, the particles can already be rotatable in the substrate, or can be rendered rotatable in the substrate by a nondestructive operation performed on the substrate. In particular, the substrate can be made up of an elastomer that is expanded by application of a fluid thereto so as to render the particles rotatable therein. A particle, when in its rotatable disposition, is not attached to the substrate. The close-packed monolayer configuration of particles provides excellent brightness characteristics and relative ease of manufacture as compared with certain other high-brightness gyricon displays.
