Patent CA-2409126-A1 (CA)
Title: Electrochemical fuel cell with non-uniform fluid flow design
Inventor: WILKINSON DAVID PENTREATH
IPC: H01M8/02
Filed: 2002-10-22
Abstract: An electrochemical fuel cell having reactant flow passages with a non-uniform design to increase reactant access to an adjacent fluid distribution layer at the outlet region as compared to the inlet region. In an embodiment, at least one reactant flow passage is narrower at the inlet than at the outlet, with a substantially constant cross-sectional area maintained along its length. Coolant channels may optionally be incorporated in the fluid flow plate to provide increased cooling at the reactant inlet. The plates may vary in thickness and run in counter-flow to improve efficient stacking of the fuel cells in a fuel cell stack with reactant passages of varying depth. In another embodiment, electrically conductive, masking foil covers a portion of at least one reactant flow passage in the inlet region, but does not extend the length of the passage.
Patent CA-2409919-A1 (CA)
Inventor: AGNEW MARTIN
IPC: H04B10/293
Filed: 2002-10-25
Abstract: An optical amplifier arrangement comprises a splitter for providing an input WDM optical signal on at least first and second output paths. An optical amplifier is provided in at least one of the paths, and a signal routing arrangement is provided for routing individual channels or groups of channels of the WDM signal within the at least one of the paths. A switch selects the signal from one of the at least first and second output paths. In this arrangement, there are two paths between the input and output. Whilst one path is being used, the components in the other path can be upgraded. For example, a switching arrangement may be provided in the other path, and an amplifier may also be upgraded, without disrupting service in the path in use. This enables an amplifying node within an optical communications systems to be incrementally upgraded.   [Fig 5]

Title: Output-compensating device for image sensor
Inventor: TAKEBE KATSUHIKO
IPC: H04N5/335
Filed: 2001-11-09
Abstract: Is disclosed an output compensating device capable of optimally compensating output signals of an image sensor composed of a number of light-sensor circuits, each of which represents a unit pixel and is capable of producing in a photoelectric converting element a sensor current proportional to a quantity of light falling thereon, converting the current into a voltage signal by a MOS type transistor with a logarithmic output characteristic in a weak inverse state, initializing itself by removing a charge accumulated in a parasitic capacity of the photoelectric converting element by changing a drain voltage of the transistor to a value lower than a normal value for a specified time and outputting a pixel signal having a logarithmic characteristic at a large quantity of the sensor current and a pixel signal having a non-logarithmic characteristic at a small quantity of the sensor current.  This device has a means for compensating each pixel signal from the image sensor for an offset value and outputting a resulting signal if said signal has an output characteristic within a logarithmic response region or a non-logarithmic region depending on the output condition and, if not, further compensating the offset-compensated signal for its gain and outputting a resulting signal, thus ensuring the optimal compensation of each pixel signal of the image sensor in accordance with its output state.

Patent CA-2432741-A1 (CA)
Inventor: CHEN WEI-GE
IPC: H04N7/30
Filed: 1996-10-04
Abstract: Video encoding and decoding processes provide compression and decompression of digitized video signals representing display motion in video sequences of multiple image frames. The encoder process utilizes object- or feature-based video compression to improve the accuracy and versatility of encoding interframe motion and interframe image features. Video information is compressed relative to objects or features of arbitrary configurations, rather than fixed, regular arrays of pixels as in conventional video compression methods. This reduces the error components and thereby improves the compression efficiency and accuracy. The decoder process decompresses the encoded video information to reconstruct the objects or features of arbitrary configurations.

Abstract: A method of repairing a flow passage is provided that allows prevention of deformation of a tubular assembly after hardening of grout material, to maintain the tubular assembly in a desired cylindrical shape. The method comprises the steps of forming a tubular assembly in a pipe, the tubular assembly having an outer diameter smaller than an inner diameter of the pipe; filling a grout material in a clearance between the tubular assembly and the inner wall of the pipe; disposing a tubular expansible and contractile pressure bag within the clearance between the tubular assembly and the inner wall of the pipe in a longitudinal direction of the pipe; filling the pressure bag with a fluid to expand the pressure bag; and supporting the tubular assembly with the expanded pressure bag. With the foregoing process of the present invention, slight deformation of the tubular assembly due to the pressure of the grout material can be absorbed through elastic deformation of the pressure bag to prevent partial deformation of the hardened tubular assembly, thereby maintaining the overall tubular assembly in the desired cylindrical shape.

Abstract: A self-mailer construction that creates a single- or double- panel inside a carrier. Die-cuts are positioned in such as way as to reduce the size of at least one internal panel. Because these panel(s) are narrow-width, they terminate short of the full-width portion of the outside panels and, therefore, are unattached at any paint other than the top edge of the sealed document.

IPC: E04H1/12
Filed: 2003-12-31
Abstract: The present invention provides a system, or kit, of injection molded panels having integrated connectors which combine to form an enclosure, commonly in the form of a utility shed. The bilaterally symmetrical panels are formed of injection molded plastic to interlock with one another without the need for separate I-beam connectors.      The ends of the wall panels have cavities to accept both roof and floor outwardly projecting interlocking posts for interlocking cooperative engagement which serve to rigidly connect the components together. The bilateral symmetry of the wall, roof, floor and door components also minimizes component shapes and simplifies enclosure construction.
