Patent CA-2268473-A1 (CA)
Inventor: MALCHESKY PAUL S
IPC: G01N21/35
Filed: 1997-10-16
Abstract: Medical and other instruments and devices (16, 44) may have a build-up of biological residue film, even after sterilizing. Dead cell membranes in this film can give off endotoxins. To check for the presence of biological residue film, light from a source (10, 40) travels along an optical path and is focused by a prism (22) or lens (92) on a surface (24) to be examined. Reflected and transmitted light is conveyed by optical fibers (12, 42) to an opto-electrical analyzing device (30, 48, 100). In one embodiment, the optoelectrical device (30) senses the intensity of reflected light to provide an indication of reflectivity attributable to the biological film build-up. In another embodiment, a spectrophotometer (48) converts the returned light into an indication of the reflected spectrum which is analyzed (50) to determine the nature of the material which reflected the light, in particular the type of protein or other biological residue found on the examined surface.

Title: Switching internet traffic through digital switches having a time slot interchange network
Inventor: TAMMARU ENN
IPC: H04Q11/04
Filed: 1999-04-26
Abstract: Apparatus and a method for interfacing between the Internet and the Telephone Network. A time slot interchange is enhanced by the addition of a supplementary memory for storing data for accumulating Internet packets. When a packet has been accumulated, the appropriate header is inserted into the packet under the control of a routing processor, and the packet can then be sent as a group of adjacent PCM samples over a connection to the Internet. In other embodiments, information is sent to the Internet over a direct data pipe for transmitting ATM cells or Ethernet packets. A Vocoder signal processor can be inserted between the TSI memory, and the supplementary memory to convert PCM voice samples into vocoded voice samples for transmission over the Internet. A modem signal processor can be interposed between the TSI memory and the supplementary memory to convert between analog data (representing for example, shift key analog signals) and binary data for transmission within packets over the Internet. Advantageously, existing TSI units can be used to interface with both the telephone plant and the Internet.

Patent CA-2276489-A1 (CA)
Title: Stable nonlinear mach-zehnder fiber switch
Inventor: PANTELL RICHARD H
IPC: G02F1/365
Filed: 1997-12-30
Abstract: An all-optical fiber switch is implemented within a short Mach-Zehnder interferometer (200) configuration. The Mach-Zehnder switch (200) is constructed to have a high temperature stability so as to minimize temperature gradients and other thermal effects which result in undesirable instability at the output of the switch. The Mach-Zehnder switch (200) of the preferred embodiment is advantageously less than 2 cm in length between couplers (230, 260) to be sufficiently short to be thermally stable, and full switching is accomplished by heavily doping one or both of the arms (235, 240) between the couplers (230, 260) so as to provide a highly nonlinear region within one or both of the arms. A pump input source (215) is used to affect the propagation characteristics of one of the arms to control the output coupling ratio of the switch (200). Because of the high nonlinearity of the pump input arm (281, 220), low pump powers can be used, thereby alleviating difficulties and high cost associated with high pump input powers.
Patent CA-2277604-A1 (CA)
Title: Canopy mounting device for exit sign
Inventor: HEATON THOMAS K
IPC: G09F13/04
Filed: 1999-07-16
Abstract: Internally illuminated emergency signs are typically placed in elevated locations which are awkward for electricians to reach, yet must be securely mounted. It is therefore difficult and time-consuming to make wiring connections after the mounting operation is completed. In order to facilitate both quick and easy wiring of the sign, and secure mounting thereof, an improved canopy features a projecting bracket which slips into a slot in a side or top of the sign housing, and engages over horizontally extending screws. Rapid, yet secure mounting of the sign is achieved by cantilevering the sign on the bracket, if side mounting is used, or by use of a locking pin, if top mounting is used. The locking pin keeps the screws from sliding laterally with respect to the bracket.
