Title: A method for compression encoding of digital picture video signals, using co-encoding of blocks from several pictures
Inventor: BJONTEGAARD GISLE
IPC: H04N7/46
Filed: 1995-09-27
Abstract: In a digital picture video signal compression encoding process for transmitting such signals via a narrowband transmission medium, two or more pictures are co-encoded by encoding/decoding blocks having the same picture position, together. First, the block of the last picture is encoded/decoded, and thereafter, the decoded result in this block is used as a prediction for the remaining blocks, together with information from previously decoded pictures. Preferably one single shift/movement vector is used in order to indicate a prediction for several blocks. In addition, transform coefficients representing difference signals to be transmitted, are interwoven from the blocks to be co-encoded, so that the transmission format for transforming coefficients will be the same as when encoding/decoding one block.

Title: Ninety degree pouring spout
Inventor: BRUCKER ROBERT J
IPC: B65D5/74
Filed: 1995-11-01
Abstract: Novel pouring spouts for a container are provided herein. The spout includes depending wings extending down from the bottom edge of the spout. The wings terminate in a point for piercing a container. The depending wings define an angle which is greater than ninety degrees with respect to the chute. Stop means are formed along the upper edges of the side walls of the spout, which permit the spout to open by pivoting about an arc of ninety degrees. The spout is inserted into a container with an apparatus which includes a ram which drives the spout against a ramp to rock the depending wings upward with respect to the bottom edge of the spout. Thereafter, the ram drives the points into the container and the upper edges of the side walls contact the container and cam the back of the spout to a horizontal position. This allows the spout with the depending wings to be inserted into a container through slits that are sized properly to receive and hold the spout in the container.

Inventor: JOHNSTON STEPHEN A
IPC: C12N15/87
Filed: 1996-04-03
Abstract: On présente un procédé général de vaccination, contre tout agent pathogène, qui implique de recourir à une immunisation par banque d'expressions, par laquelle on inocule à un animal une banque d'expressions construite à partir d'ADN génomique fragmenté provenant d'un agent pathogène. Tous les épitopes potentiels des protéines de cet agent sont codés dans son ADN et l'immunisation génétique permet d'introduire directement un ou plusieurs clones de banque d'expressions dans le système immunitaire, ce qui provoque une réponse immunitaire à la protéine codée. On a démontré que l'inoculation de banques d'expression représentant des parties du génome de Mycoplasma pulmonis protège des souris des provocations ultérieures de cet agent pathogène naturel. Ce procédé a aussi permis de conférer une protection contre Listeria.

Title: Motion analysis system
Inventor: FYFE KENNETH RICHARD
IPC: A61B5/103
Filed: 1997-10-09
Abstract: A device comprised of at least a pair of accelerometers and a tilt sensor mounted in fixed relation to a datum defining plane (sole of a shoe) maybe used for extracting kinematic variables including linear and rotational acceleration, velocity and position. These variables may be resolved into a selected direction thereby permitting both relative and absolute kinematic quantities to be determined. The acceleration is determined using a small cluster of two mutually perpendicular accelerometers mounted on a shoe. Angular orientation of the foot may be determined by double integration of the foot's angular acceleration (which requires a third accelerometer substantially parallel to one of the two orthogonal accelerometers). The two orthogonal accelerations are then resolved into a net horizontal acceleration or other selected direction which may be integrated to find the foot velocity in the selected direction.      The average of the foot velocity corresponds to the subject's gait speed.

Title: Lens adjustment device of stereo camera
Inventor: INABA MINORU
IPC: G03B35/00
Filed: 1997-12-09
Abstract: A lens adjustment device of a stereo camera of this invention operates adjustment rings of right and left lenses of an optical axis distance variable type stereo camera in the interlocking arrangement with each other. Crank arms are provided on stop adjustment rings of lenses mounted on the right and left lens boards capable of adjusting the distance between the optical axes.  The right and left crank arms are disposed in symmetry of rotation at 180°.      The center of a lever in a vertical direction is fitted to a shaft on a slide frame.  The upper end portion of the lever and one of the crank arms are interconnected by a link, while the lower end portion of the lever and the other crank arm are interconnected by another link.  When the distance between the optical axes of the right and left lenses is changed by an adjustment mechanism for adjusting the distance between the optical axes, the lever rotates while the stop adjustment rings are kept fixed.  When one of the stop adjustment rings is rotated either to the right or the left, the other adjustment ring, too, is rotated in the same direction and at the same angle through the links and the lever, so that stop adjustment of the right and left lenses operates in the interlocking arrangement irrespective of the change of the distance between the optical axes of these lenses.

Abstract: A refrigeration system (10) with a heat reclaim (11,11') is comprised of at least one compressor (12, 12') for compressing hot refrigerant low pressure gas from at least one evaporator (29) to elevate the gas pressure to an operating high pressure level. A remote condensor (19) is connected to the compressors (12, 12') through a directional controlled valve (13) whereby to control the high pressure refrigerant gas to produce a cooled operating liquid refrigerant for feeding at least one evaporator (29). At least one heat reclaim coil (11, 11') is connected to the directional controlled valve (13) for cooling the high pressure gas from the compressor (12, 12') to recover a substantial portion of the heat from the high pressure gas .      A controller device (20) is connected to an outlet (17) of the heat reclaim coil to sense the pressure of the refrigerant gas at the outlet and to control a valve network (21) to section the remote condensor coil (25) or bypass the remote condensor (19). The refrigerant gas being fed to the remote condensor (19) from the outlet of the heat reclaim coil passes through the remote condensor or sections thereof or bypasses the remote condensor depending on the state of the valve network (21) controlled by the controller device (20). The valve network (21) is actuated dependent on the pressure at the outlet (17) of the heat reclaim coil (11') whereby refrigerant gas pressure at that outlet is controlled to prevent excessive pressure drop by the remote condensor which can shut down the refrigeration system (10).
