Patent CA-2314456-A1 (CA)
Inventor: BOYCHUK JERALD JOHN
IPC: C09J7/22
Filed: 2000-07-21
Abstract: A tear tape for attachment to an overwrap material is formed by longitudinally drawing a bi-axially oriented film of a polymeric material, preferably polyester so as to effect further orientation in the longitudinal direction.  After drawing a layer of a pressure sensitive adhesive is applied on one surface a nd a release coat is applied to the other surface so as to provide a release acti on when contacting the pressure sensitive adhesive. The film is longitudinally slit with the adhesive layer thereon into a plurality of side by side tapes which are woun d into individual supply packages for supply to an end use machine. The additional drawing can be carried out at a draw ratio and at a temperature such that th e heat shrink characteristics of the tape are matched to the overwrap material for heat shrinking of the overwrap onto the underlying product without puckering. The  extra longitudinal strength imparted by the drawing allows the formation of a thinner tape while matching the absolute strength value required to carry out the tearing  action.

Title: Apparatus and method for applying mud to drywall tape
Inventor: KORMOS DAVE
IPC: E04F21/00
Filed: 2000-06-15
Abstract: A method for applying drywall mud to drywall tape allowing for lengthy stoppages in a drywall application process comprises threading the drywall tape through mud in a container. When the drywall process is interrupted, a strip of material. is attached to at least one surface of the drywall tape between the roll and the container. The strip of material is substantially longer than the distance across the container and has a tensile strength substantially unaffected by prolonged exposure to drywall mud. The drywall tape with attached material is drawn through the container until both ends of the strip of material extend outside the container on opposite sides thereof. The container is sealed and the apparatus, with tape still threaded through the container may now be left for a prolonged period of time. When it is desired to re-commence the drywall process, the drywall tape and applied material is drawn through the slots until the material exits the container and is torn off and discarded, leaving a free end of drywall tape outside the container available for grasping and pulling more drywall tape. The material is conveniently adhesive tape. An apparatus for conveniently applying mud to drywall tape is also provided.

Title: Video signal processor
Inventor: HAMADA MASANORI
IPC: H04N5/14
Filed: 1999-02-18
Abstract: A phase control circuit sets the phase of a sampling clock signal for A/D conversion of a video signal in order. A binarizing circuit binarizes an analog video signal. A first counter circuit counts the changes of the output signal of the binarizing circuit. An A/D converting circuit digitizes the input signal. A  second counter circuit counts the changes of the most significant bit of the A/D  converting circuit. A subtracting circuit subtracts one from the other of the output signals of the two counter circuits. By changing the phase of the sampling clock signal of the A/D conversion in order within one period, the subtraction results are found, and this process is repeated for one or more periods. Thus the phase of the optimum sampling clock is set according to the subtraction results.

Abstract: While ice skating or in-line roller skating, a big effort is imparted on our ankles to support our body weight. Therefore, hockey players for example, will apply a plastic tape around the ankles for additional support. Tape however, doesn't provide a uniform and constant support, it hampers flexibility and it greatly pollutes the environment. Practically, it is a chore to install and remove the tape every time you want to go skating. Finally, even more tape is needed to hold the shin pad in place. The invention is composed of an elongated elastomeric strip of a minimal thickness and an important width. To each end is affixed quick-release fasteners. Hence, the practical inconveniences mentioned earlier are resolved by the simplicity of the invention. One advantage is the quick and simple one step application. The width of the invention allows hockey players to hold the bottom of the shin pad at the same time.  Finally, the elastomeric strip's thinness will allow the invention to mold to the exterior of the equipment it is in contact with, providing a good tension and a uniform and constant support, without compromising flexibility.

Abstract: A stylus with biometric sensors captures a wide variety of biometrics while the pen is being used. The stylus is the centerpiece of a system to enable conversion from a card-based commercial transaction system to a cardless commercial transaction system. The stylus senses the prints of the index finger and thumb along with other properties, while the customer uses the stylus to sign his name. In signature verification systems currently in use, pen-like systems are used, but prints are not being measured. The stylus enables the conversion at point-of-sale terminals when used to verify signatures, and in closed environments where house cards are issued for a limited purpose or within a limited area. Initially, the stylus will replace existing pen-like systems for signature verification. Once used for signature verficiation, the credit card becomes optional. Applicants can also use the stylus to participate in government programs (such as subsidies, voter registration, and driver's licenses).
Patent CA-2331913-A1 (CA)
Title: Base station transceiver to radio network controller synchronization filtering function
Inventor: STICHTER ALLEN WILBUR
IPC: H04L7/00
Filed: 2001-01-23
Abstract: A method that initiates several time synchronization passes between clock slave components and a clock master component in a wireless telecommunications system is provided. For every pass, each clock slave component generates and transmits a first timing cell to the clock master. The first timing cell contains a transmission time based on the clock slave component's clock. Upon receipt of the first timing cell, the clock master generates and transmits to the clock slave component a second timing cell containing the time the clock master received the first timing cell and the time the master transmitted the second timing cell. Upon receipt of the second timing cell, the clock slave component will obtain its reception time and calculate a transmission delay based on the reception time and the timing information contained in the timing cells. Each clock slave component utilizes a filtering function to drop information from a synchronization pass that may have undesirable data due to processing and other delays. The filtering function will also restart the synchronization process whenever a calculated transmission delay is smaller than the best delay. This allows the process to accurately hone in on the proper delay experienced between each clock slave component and the clock master. After timing information from a predetermined number of time synchronization passes has been obtained, each clock slave component uses an average transmission delay to synchronize its time to the clock master time.

Title: High gain fluid control valve assembly
Inventor: CAMPAU DANIEL N
IPC: F16K31/00
Filed: 2001-01-24
Abstract: The valve assembly of the present invention includes a body portion having one or more inlets and two aligned outlets. The outlets are located on opposing faces of the body portion, one having a generally rigid valve seat defining a first valve outlet port and the other having a generally flexible valve seat defining a second valve outlet port. The valve assembly also employs a valve support assembly configured to move relative to the body portion generally along the axis of the aligned outlets. The support assembly has a flexible valve member at one end positioned inside the body portion and configured to engage the rigid valve seat to block flow through the first valve outlet port. The support assembly also has a generally rigid valve member positioned outside the body portion and configured to engage the flexible valve seat to block flow through the second valve outlet port.      With this construction, when the valve support member is in an open position, both the flexible and rigid valve members are spaced from the rigid valve seat and flexible valve seat, respectively, allowing flow of fluid through the valve. However, when the valve support assembly is moved to the closed position, both the valve members are in contact with their respective valve seats and fluid flow is blocked.
