Patent CA-2173432-A1 (CA)
Inventor: BRIDGES RUSSELL PIERCE
IPC: A61F5/44
Filed: 1994-10-06
Abstract: A method and apparatus for forming a tensioned garter and bondingit to a substrate while holding the garter in a predetermined shape. A garter is any continuous loop of elastic material or a laminate of elastic bands and one or more flexible backing sheets. In one embodiment mandrels having a perimeter of the desired garter shape are mounted to a rotating drum. Tensioned elastic ribbons are progressively wrapped, sealed, and cut around the mandrels to form individual tensioned garters which cling to the side walls of the mandrels. In another embodiment each mandrel has a top surfce. The upper portion of a garter has sufficient elastic tension to cause it to fold over the mandrel top surface to form a garter flange thereon. A substrate is then engaged with the garter flange and an external sealing means seals the flange to the substrate, using the mandrel top surface as an anvil. In still another embodiment the mandrel top surface has a raised outer rim. An ultrasonic horn seals a garter flange to a substrate where they are supported by the mandrel rim. The mandrel rim is shaped to provide a continuous seal which is weakened at its inner edge. When the weakened edge is broken, substrate and garter materials inside the seal edge are removed, thereby forming a hole around which the remaining portion of the garter may contract. Vacuum is applied from the mandrel top surface to the substrate inside the garter in this embodiment in order to break the seal edge and remove this material as the substrate and garter are stripped off the mandrel.

Title: Relief Valve Seat for Positive Displacement Pump
Inventor: SCHROEDER ALFRED A
IPC: F04B53/10
Filed: 1994-10-28
Abstract: A positive displacement pump (50) includes a relief valve comprising a valve seal (61), a needle (62) within the valve seat, a spring (63) forcing the needle within the valve seat, a set screw (65) pressing the spring against the needle and a spacer (64) for mounting the set screw to the housing of the positive displacement pump. The valve seat threadably con-nects within the relief valve passageway to prevent the erosion of the passageway. The valve seat may be constructed from a plastic, hard rubber, or metal material and include a rubberized seal secured at one end of the valve seat. When the valve seat erodes to a point where it provides an insufficient seat for the needle, it is re-moved from within the relief valve pas-sageway and replaced with a similar valve seat. By protecting the relief valve pas-sageway from erosion by using am inex-pensive, removable, and disposable valve seat, costly disposal or machining of the housing of the positive displacement pump is avoided.

Title: Method and apparatus for coding chrominance information in a low bit rate color video coder
Inventor: PODILCHUK CHRISTINE IRENE
IPC: H04N19/94
Filed: 1996-08-21
Abstract: A method and apparatus for low bit rate coding of color video signals in which the use of the codebook entry identified by the codebook index may be bypassed in the coding of chrominance information when it is determined that it is advantageous to do so. In particular and in accordance with an illustrative embodiment of the present invention, the method comprises the steps of generating a codebook index signal based on the luminance information of the block being coded; determining a coding error based on a comparison of the chrominance information contained in the given block and the chrominance vector represented by the generated codebook index signal; and generating a chrominance vector bypass signal based on whether the coding error exceeds a threshold. Specifically, the chrominance vector bypass signal is used to indicate whether the chrominance information of the given block has or has not been coded with use of the codebook. In one illustrative embodiment, the motion-compensated interframe prediction for the given block is used (without any interframe codebook difference vector adjustment) to code the chrominance signal when the chrominance data from the indexed codebook entry is not used (i.e., when it is bypassed).

Title: Method and devices for wavelength and power demodulation based on the use of a quantum well electroabsorption filtering detector
Inventor: COROY TRENTON G
IPC: H04B10/158
Filed: 1996-11-20
Abstract: Devices for measuring one or more properties of a light signal is disclosed. More particularly the invention relates to devices for wavelength and power demodulation based on the use of quantum well electroabsorption photodiodes. In one aspect the invention provides and power and wavelength demodulation system based on a quantum well electroabsorption (QWEA) filtering detector. The input optical signal passes through an optical beam splitter with part of the signal input into a filtering detector which is a multiple quantum well electroabsorption (MQW EA) photodiode having a tunable bandgap and the other part into a reference detector. The input light signal is impinged on the QW diode perpendicular to the plane of the quantum wells. The output of filtering detector is amplified by an amplifier and the output of the reference detector is input into another amplifier. The output from reference detector amplifier serves as a measurement of the power of the input optical signal. The outputs of the amplifiers are input into an analog divider circuit where the signals are ratioed. A ratiometric voltage signal, Vratio, is obtained by ratioing the filtered output of filtering detector and the unfiltered reference output to provide optical intensity self-referencing (immunity to input power fluctuations). This Vratio output signal is continuously compared with a reference voltage signal, Vref, and the difference of Vratio and Vref is input into a feedback control circuit. The output voltage Vout of the feedback control circuit is used to bias the QW EA photodiode so that in closed loop operation the QW EA photodiode is continuously wavelength tuned to maintain Vratio equal to Vref.
