Patent CA-2181078-A1 (CA)
Title: Wavelenght division multiplexing optical transmission network
Inventor: SOTOM MICHEL
IPC: H04L7/00
Filed: 1996-07-11
Abstract: The information network has an optical link (L) and a multiplexers (θ i) for transferring messages (Mi,Mj) between nodes (Ni,Nj) which comprises a sub-unit of the network. The messages are contained in defined time intervals by a clock signal (SP) and each node has an input (Ei) connected to the link for receiving messages by detection of at least one specific signal wavelength. Each node has an output connected to the link to allow emission of messages which are wavelength modulated. The network is characterised by each node for which provision is made to carry messages to be output at a specific wavelength and have associated with them respective tags (Dij) for identifying the destination nodes for the message. The network controller is connected to the link and is conditioned to receive messages and tags emitted by each node and to re-emit or transmit the received messages towards the input of the destination node. The retransmitted messages are output at a wavelength corresp. to the reception wavelength of the destination node identified by the tag. Each node has a different reception wavelength.

Title: A brake monitoring device for railroad cars
Inventor: MARUTA SEIKI
IPC: B60T13/74
Filed: 1996-07-30
Abstract: A  brake monitoring device for railroad cars is provided with a first comparison means which compares the electrical brake power equivalent signal with a first standard value, judges whether or not electrical brake power is generated and closes the locomotive brake deficit check circuit with an interlock means when such electrical brake power equivalent signal is smaller than such first standard value and which opens the locomotive brake deficit check circuit when it is larger.  Such brake monitoring device also includes a second comparison means which compares the electrical brake power equivalent signal with a second standard value which judges whether or not electrical brake power is supplied to the brake power of the trailer car.  Such device closes the trailer car brake deficit check circuit with such interlock means when the electrical brake power equivalent signal is smaller than the second standard value and opens the trailer car brake deficit check circuit when it is larger.  Thus, in cases where brake power is not supplied to the trailer car, even if brake power is generated, it is still possible to greatly improve the safety and simplicity of the delayed-action control brake device.

Patent CA-2185385-A1 (CA)
Inventor: ALLEN GARY R
IPC: G02B6/28
Filed: 1996-09-12
Abstract: Disclosed are optical couplers and optical coupling systems for coupling a source of non-coherent light to a light distribution harness, wherein the couplers are polygonal in cross section to increase light mixing. The couplers have inlet and outlet arms, and an intermediate bend region configured to achieve compactness and minimal light loss through the bend region. In one embodiment, the bend region is an integral part of the coupler, with the inlet arm having a different cross-sectional dimension from the outlet arm in such manner that substantially all light directed from the inlet portion to the bend portion reaches the outlet arm portion, and light raysparallel to the inlet axis are reflected in the bend portion to be directed substantially parallel to the outlet axis. In a second embodiment, the bend region comprises a prism having a pair of parallel spaced surfaces, and inlet, outlet, and third surfaces that are non-parallel to the spaced surfaces. The inlet arm projects from the inlet surface, and the outlet arm projects from the outlet surface. One of the inlet and outlet surfaces forms a first interface with a first material having an index of refraction different from that of the prism, so that light rays within the prism totally internally reflect from the first interface.

Title: Method and apparatus for machine health inference by comparing two like loaded components
Inventor: SCHOLL ROLLAND D
IPC: F02B75/18
Filed: 1995-06-22
Abstract: A method and apparatus are disclosed for monitoring similar machine components loaded in parallel to produce diagnostic trend information used to predict component degradation or failure. Split exhaust manifolds (18, 20) are each provided with a sensor (26) to produce signals indicating exhaust temperature. A diagnostic monitor (30), which includes a trending module (32), receives the temperatures and periodically determines a difference between the temperatures, and averages the differential values over a predefined trend period to generate trend values. A plot of the trend based on the trend values is generated and monitored for changes which indicate the possible degradation of one of the components. The data monitoring and trending can be used with both stationary and mobile machines and may be performed either onboard or remotely from the machine (36, 37).

Patent CA-2192939-A1 (CA)
Title: Seaplane hull
Inventor: LABOUCHERE JAMES
IPC: B64C35/00
Filed: 1995-06-16
Abstract: A seaplane hull has a high length/beam ratio, substantially fair topside waterlines from bow to stern and a fine bow entry angle. These characteristics disperse the water little, offering the hull low wave-making drag characteristics which enable it to achieve high speed without requirement for planing lift. Chines (4) on the underside describe a slim planing surface, the edges converging aft toward the central plane. The slim planing surface minimises wetted area at speed, and low pressure hollows (6) are provided immediately above the chines (4) for air to travel aft and under an afterbody when at speed. The design enables continuity of aerodynamic and hydrodynamic streamlines throughout acceleration to take-off speed.

Title: Alertness and drowsiness detection and tracking system
Inventor: LOPARO KENNETH ALAN
IPC: G08B21/06
Filed: 1997-04-03
Abstract: A drowsiness detection system constructed according to the invention provides improved performance by preserving and analyzing newly discovered information contained in rhythmic signal components above 30 Hz which the prior art has universally ignored or discarded as "noise." In the first and second embodiments of the invention, one or more analog EEG signals are collected from a subject, appropriately filtered, converted into digital form, and subjected to frequency analysis. Selected signal components from the frequencies above 30 Hz (such as the frequency range 80-420 Hz), which have a high correlation with subject drowsiness, are isolated, and their amplitude, energy, or power contribution to the EEG signal is used to produce a continuous output measure reflecting the subject's alertness or drowsiness. The output measure may be compared with a threshold to provide an indication of whether the subject is excessively drowsy. In a third embodiment, the analog EEG signal is supplied to a plurality of analog signal processing channels corresponding to respective predefined frequency ranges. Selected signal components in frequencies above 30 Hz are isolated (in a manner analogous to that of the first and second embodiments), and their amplitude, energy, or power contribution to the EEG signal is used to produce a continuous output measure reflecting the subject's alertness or drowsiness.

The fabric is assembled by engaging and interlocking the jointing yarns or formed structures, for example by overlapping the segments, in either a spiral winding process or piecewise fashion, so that the jointing yarns or structures provided in the segment ply are engaged and interlocked. Further secondary processing of the joint is not required. The at least one segment may be a single continuous strip, a plurality of strips, or panels, into which the jointing structures have been incorporated.
