Patent CA-2014854-A1 (CA)
IPC: H04N5/14
Filed: 1990-04-18
Abstract: A circuit for carrying out a full search block matching algorithm with fractional pixel precision comprises a first subcircuit for obtaining displacement vectors with integer pixel value precision and a second subcircuit for correcting the displacement vectors obtained by the first subcircuit so that the displacement vectors have fractional pixel value precision.  To obtain a displacement vector with integer pixel value precision for a block of pixels of a current video frame in a search area of a previous video frame, the first subcircuit finds a first specific position of the block with the smallest error out of a first plurality of positions defined by integer pixel values in the search area. The second subcircuit interpolates the integer pixel values of the first specific position to obtain fractional pixel values which define a second plurality of positions in the search area. The second subcircuit then determines which position of the block in the second plurality of positions has the smallest error, thereby providing a correction with fractional pixel precision for the displacement vector.

The balls (6) which transmit the force are maintained in non-positive contact with the bearing (5) by a freely rotating inertial race (7) and are also guided by guides located in the housing (2a) itself and in the output part (3). One of these guides consists of either radial guide grooves (10) or a continuous fluted groove and the other consists of a continuous fluted sliding channel (11); the number of flutes is different from the number of radial guide grooves (10) and from the number of flutes of the first flutes sliding channel, and the number of balls is equal to the number of radial grooves (10) and to the number of points of intersection of the two fluted sliding channels with the reference circle.  In a transmission in which the force-transmitting balls (6) are guided on one side in radial guide grooves (10), the ratio of the number of balls (6) and hence the number of radial guide grooves (10) to the number of flutes of the fluted sliding channel (11) is between n:(n-2) and n:(n+2), whereas in a transmission in which the force-transmitting balls (6) are guided on two sides in fluted sliding channels (11), the ratio of the number of balls (6) and hence the number of flutes in one fluted sliding channel to the number of flutes in the other fluted sliding channel (11) is at least equal to n:( +/- 2).

Title: Fiberoptic interferometric sensor
Inventor: LIPSON DAVID
IPC: G01N21/41
Filed: 1991-03-12
Abstract: ABSTRACT OF THE DISCLOSURE      An optical fiber interferometric system includes a pair of single-mode, polarization-preserving fibers having distal and proximal ends.  The cladding of a selected portion of one of the fibers having been removed to allow an evanescent portion of a light wave traveling within the fiber to interact with any medium surrounding the selected portion of the fiber.  A light source for producing a light of known character is coupled to the proximal ends of the pair of optical fibers for introducing a source signal to the pair of fibers.  A reflector at the distal ends of the optical fibers reflects the light from the distal ends back toward the light source.  The return signals are used to construct an interferogram which is observed to detect any modulation in the the phase of the light signals.  The modulation is examined ratiometrically to derive a change in the index of refraction of the medium surrounding the selected portion substantially free of any environmentally induced phase noise.

Title: Fish Retaining Device
Inventor: OLSZOWKA STANLEY J
IPC: A01K97/01
Filed: 1991-08-12
Abstract: A fish retaining device consisting of an elongate support having a first end and a second end.  A transverse brace member is secured to the first end of the elongate support for suspending the elongate support in an opening made through ice for ice fishing such that the second end of the elongate support extends toward a bottom of the ice opening.  A frame is secured to the second end of the elongate support.   The frame has a central passage and extends substantially perpendicular to the elongate support.  The frame substantially fills the ice opening such that there is no room for a fish to pass between the frame and the ice opening.  A one-way gate is pivotally mounted to the frame.  The gate pivots toward the first end of the elongate support such that clearance is provided for the passage of a fish through the central passage of the frame into the ice opening.  The gate rests upon the frame which serves as a stop preventing the gate from pivoting toward the second end of the elongate support thereby closing the central passage and retaining the fish within the ice opening.

Filed: 1991-08-13
Abstract: DESCRIPTIVE ABSTRACT        In order to break up agglomerated solid particles sus-pended in a liquid, e.g. fines obtained during the reprocessing of nuclear fuels, the liquid is circulated under pressure in venturi tube (44).  The radial gradient of the velocities within the latter induces shear forces, which disintegrate the aggregates.  The effect is increased by recirculating part of the liquid in the venturi tube, which then serves as an ejector.  The venturi tube is preferably vertically oriented, the liquid flowing downwards.  A baffle system can be placed at the outlet from the venturi tube.         (Fig. 1)
