Patent CA-2243910-A1 (CA)
Inventor: FORBES JAMES WILFRED
IPC: B61D3/20
Filed: 1998-07-23
Abstract: A railcar unit has a pair of opposed side sills that are joined by structure that performs the function of a web in a deep beam or bracing in a truss. The joining structure is able to transmit loads that are applied transversely to the longitudinal direction of the car from one sill to the other, and is also able to transmit a bending moment couple, in the form of opposite longitudinal tensile and compressive forces, also transmitted to the side sills. The locations at which the transverse forces are imposed on, or by, the intermediate structure have longitudinal slip. When the railcar unit is placed in longitudinal tension under draft loads, the longitudinal slip allows the floor structure not to be subject to the longitudinal draft loads. In the embodiment described the joining structure serves the additional function of acting as a floor panel for vertical loads carried within the well car unit.

Title: Implantable sensor and system for in vivo measurement and control of fluid constituent levels
Inventor: CROTHALL KATHERINE D
IPC: A61B5/00
Filed: 1997-07-08
Abstract: An in vivo implantable sensor (10) obtains spectra of body fluid constituents, and processes the spectra to determine the concentration of a constituent of the body fluid. The sensor includes an optical source (12), and detector (16). The source emits light at a plurality of different, discrete wavelengths, including at least one wavelength in the infrared region. The light interacts with the body fluid and is received at the detector. The light at the plurality of different wavelengths has a substantially collinear optical path through the fluid with respect to each other. When measuring fluid constituents in a blood vessel (14), such as blood glucose, the light at the plurality of different wavelengths is emitted in a substantially single period of time. The spectra are corrected for artefacts introduced from extraneous tissue in the optical path between the source (12) and the detector (16).

Title: Communications network
Inventor: COTTER DAVID
IPC: H04L45/16
Filed: 1997-08-12
Abstract: A communications network, suitable, for example, for linking computer processors, is formed from a number of nodes and links. The nodes and links are configured as a multiplicity of directed trails.      Each directed trail spans some only of the nodes, but in combination the directed trails span every node of the network. Packets are routed through the network by selecting the appropriate one of the directed trails which links the source node and destination node, and by outputting the packet at the source node onto the selected trail. The nodes throughout the network may switch between predetermined and prescheduled switching states, and a given trail may be selected by choosing appropriately the time slot in which the packet is put onto the network. The network may be a photonic network carrying optical packets.
