Patent CA-2111866-A1 (CA)
Title: Spray dispenser
Inventor: WILLIAMS JOHN E
IPC: B65D83/14
Filed: 1992-06-19
Abstract: A spray dispenser comprises a container (12) in which a product-containing bellows (80) is situated above an energy storing bellows (82). A piston (70) is disposed within the container (12) below the energy storing bellows (82). A sleeve (40, 42) surrounds the container and is threadedly connected with the piston (70) where by rotation of the sleeve (40, 42) relative to the container (12) causes the piston (70) to rise and compress the energy storing bellows (82). The energy storing bellows (82) thus pressurizes the product-containing bellows (80) to expel the product when the valve (60) is opened. The outer diameter of the bellows (80) is of progressively reduced diameter to enable the bellows segments to become more snugly nested within one another when collapsing.

Title: Electrophoretic Display Panel with Selective Line Erasure
Inventor: DISANTO FRANK J
IPC: G02F1/167
Filed: 1991-08-28
Abstract: An electrophoretic display apparatus has grid (10) and cathode (4) conductors arranged as an X-Y matrix spaced from an anode (14) with an electrophoretic dispersion in between them. Pigment particles in the dispersion become charged at selected intersection areas of the X-Y matrix and migrate towards the anode (14) to form a display image thereon by biasing the cathode (4) negatively with respect to the anode (14), and the display image is erased by oppositely biasing the cathode (4) and anode (14). The anode (14) is formed with a multiplicity of parallel anode line segments (62) corresponding to image lines of the display, and control circuitry is provided for individually controlling the potential applied to each anode line segment (62) in order to allow selective erasure of one or more lines and rewriting of only those lines. A new image frame having a substantial portion thereof the same as a previous frame can thus be rewritten in a shorter time.

Patent CA-2117006-A1 (CA)
Title: Noise reduction system using multi-frame motion estimation, outlier rejection and trajectory correction
Inventor: IU SIU L
IPC: H04N7/26
Filed: 1994-03-04
Abstract: ABSTRACT           A Video signal noise reduction system is disclosed in which image pixels are tracked across multiple frames and then averaged to produce respective noise reduced pixel values.  In the disclosed exemplary embodiment of the invention, a motion estimator identifies a motion block within several video frames and determines an approximate velocity vector using a trimmed square estimation procedure.  Trajectory correction is applied to each pixel in the motion block based on the velocity vector in order to determine a revised trajectory for the pixels.  This correction is accomplished by determining a difference in position of a motion block between successive video frames.  Based upon this revised trajectory, appropriate pixels corresponding to the motion block are obtained.  These pixels are used in conjunction with pixel values obtained from each of the processed frames to produce an averaged video frame. Each pixel of the averaged video frame replaces the corresponding pixel in the original frame if the difference between the original pixel and the corresponding averaged pixel is less than the median difference between all of the original and averaged pixels.

Title: Protamine-responsive polymeric membrane electrode
Inventor: YUN JONG HOON
IPC: C12M1/40
Filed: 1995-07-11
Abstract: A polymeric membrane electrode gives potentiometric responses to macromole-cules, such as protamine, in solution or biological specimens. A protamine-responsive membrane includes a lipophilic cation-exchange material for ionic macromolecules in a specially formulated plasticized, polymeric matrix material. Potentiometric response to protamine has been observed in membranes comprising 30-70 wt.% polymeric matrix material, such as polyvinyl chloride; 1-3 wt.% salt of a tetraphenylborate, such as potassium tetrakis(4-chlorophenyl) borate or salt of an organophosph(on)ate, such as calcium bis-[4-(1,1,3,3-tetramethylbutyl)phenyl] phosphate; and 30-70 wt.% of a plasti-cizer, such as 2-nitrophenyl octyl ether or tris (2-ethylhexyl) phosphate. The potentio-metric response of these membranes to protamine can be used to study the binding inter-action of protamine with heparin (both native and low molecular fractions) or to monitor protease activity, for example, by following the rate of degradation of intact protamine or a synthetic substrate by trypsin, as well as to measure protamine concentration in bio-logical fluids, such as blood or plasma.
