Filed: 1997-07-22
Abstract: A process and a device operating in real time for identifying and localizing an area in relative movement in a scene and determining the speed and oriented direction of the relative movement in real time. The process carries out temporal processing of a digital video input signal S(PI) that includes deducing, from the variations between the value of each pixel in a frame and in the immediately preceding frame, a binary signal DP identifying whether or not there was a significant variation and a digital signal CO representing the magnitude of this variation, and a spatial processing including distributing in a matrix these two signals successively for a single frame that is scanned through the matrix, and deducing the required relative movement and its parameters from this matrix distribution. The device includes a temporal processing unit associated with a memory and a spatial processing unit associated with a delay unit, a clock unit and control unit to control the rate of operation of the temporal and spatial processing units.
Patent CA-2261962-A1 (CA)
Inventor: SCHWINGLE JAMES P
IPC: E06B9/58
Filed: 1997-07-22
Abstract: A curtain edge tensioning assembly comprised primarily of a portion of the curtain extending across the leading edge of the door. The curtain portion is releasably coupled to a guide extension extending beyond the leading edge of the door and engaging guide members to guide the door in a plane. The guide extensions also engage the guide members to restrict the guide extensions from moving toward the center of the curtain. The releasable coupling between these horizontally restricted guide extensions and the resilient member places a tension on the curtain portion. The curtain portion is thus stretched across the door, and serves as a wind retention bottom bar or edge that also substantially conforms to or deflects around an obstruction, thus preventing or minimizing damage to the door, the bottom bar and the obstruction.

Title: Dispensing pump
Inventor: HERSHEY DONALD EMERSON
IPC: B65D47/34
Filed: 1997-09-05
Abstract: A dispensing pump (12) including an actuator (18) coupled to a resilient bellow (20), wherein the bellow (20) is in fluid communication with the contents of a container (10) via an inlet valve (34). Expansion of the bellow (20), caused by the resilience of thebellow (20), creates negative pressure causing the contents of the container (10) to be drawn through the inlet valve (34) and into a space defined by the bellow (20). The dispensing pump (12) also includes an outlet valve in fluid communication with the bellow such that compression of the bellow caused by the application of pressure to the actuator creates positive pressure within the bellow causing the contents held within the bellow to be forced through the outlet valve and out of an outlet of the dispensing pump. A closure arm (68) mounted within the bellow (20) is movable between a first position where the closure arm (68) prevents the inlet valve (34) from opening and a second position where the closure arm (68) is not a hindrance to the flow of material through the inlet valve (34).
Patent CA-2266277-A1 (CA)
Inventor: DAL FARRA DAVID
IPC: H04M9/08
Filed: 1999-03-23
Abstract: The invention relates to an acoustic echo canceller particularly well suited for use in a hands-free terminal or teleconference system. The echo canceller is designed to assess the inherent signal attenuation occurring in the analog loop that connects the terminal to the switch mechanism of the PSTN domain or the PBX domain. The echo canceller is then adjusted in accordance with the degree of signal attenuation manifested by the loop. For high signal attenuation levels, the degree of echo control at the terminal is reduced since the signal attenuation occurring in the loop itself will compensate for the reduction, allowing to reach the echo control target at the far end of the loop (switch side). This feature avoids overly attenuating the echo at the terminal by taking advantage of the inherent echo control provided by the local loop conductors.

Title: A thermal solvent process for the recovery of heavy oil and bitumen and in situ solvent recycle
Inventor: THIMM LAURA
IPC: E21B36/00
Filed: 1999-08-31
Abstract: A method for the in-situ recovery of viscous petroleum hydrocarbons from an underground formation includes the following. A production well is provided within the formation. Solvents are maintained in the formation above the production well which are capable of dissolving in and diluting the hydrocarbons to promote drainage of the solvent-diluted hydrocarbon toward the production well. A vapour chamber is created above the production well in the hydrocarbon-depleted formations resulting from said drainage. A hot zone is maintained adjacent the production well to vaporize the solvents contained in the downwardly draining hydrocarbons prior to their entry into the production well. These vaporized solvents move upwardly through the vapour chamber in a continuing manner to again contact said hydrocarbons in the formations at the boundaries of the vapour chamber to promote the continued dilution and drainage of the hydrocarbons toward said production well whereby a substantial portion of the solvents are recycled in a closed-loop fashion. Special concentric tubing closed loop heating systems provide the desired hot zones to enhance the operation of the process as required.

Abstract: Disclosed is a method for efficient material application onto substrates or removal therefrom, whereby a scanning probe microscope working under atmospheric pressure is used. According to the inventive method, the substrate is placed in a vessel, which is located on the x-y support of a scanning probe microscope (SXM) and filled with a liquid or gas medium up to a level where the top face of the substrate is covered with a thin layer consisting of at least one monolayer of said medium. In order to cause the medium to produce a structured deposit, or to attack the substrate surface in a structured manner, the microtip of the scanning probe microscope is then dipped into the layer while electric voltage or voltage pulses are applied. The inventive method can be used to apply material onto substrates or remove it therefrom. It can also be used to characterize the geometry of microtips, renew or produce microtips for SXM consoles and to record, read out and erase information.

Title: Method and apparatus for providing orthogonal spot beams, sectors, and picocells

Filed: 1998-09-08
Abstract: A method and apparatus for providing orthogonal spot beams (14a, 14b), sectors (16a, 16b), and picocells (18). The transmissions can be made orthogonal by using orthogonal auxiliary pilots and different Walsh traffic channels in adjacent areas. In accordance with the IS-95 standard, the pilot signal is covered with the 64-chip Walsh sequence zero.  The 64-chip all zeros Walsh sequence can be designated as P  and the 64-chip all one sequence can be designated as M. In the present invention, additional pilot signals can be provided by concatenating 64-chip all zeros P and all ones M sequences. Thus, for two pilot signals, pilot Walsh sequences of PP and PM can be used. For four pilot signals, pilot Walsh sequences of PPPP, PMPM, PPMM, and PMMP can be used. The present invention can be extended such that any required number of pilot Walsh sequences can be generated by substituting each bit in an K-bit Walsh sequence with the 64-chip all zeros P or all ones M sequence depending on the value of that bit.
