Title: Seat belt retractor
Inventor: FUJIMURA YOSHIICHI
IPC: B60R22/40
Filed: 1992-04-10
Abstract: ABSTRACT OF THE DIScLOSURE In a seat belt retractor according to the present invention, lock actuating means is actuated to engage locking pins with the engagement portion of a frame when deceleration in excess of a predetermined value acts upon the vehicle and/or when the seat belt is pulled at an acceleration in excess of a predetermined value.          Reliable engagement is achieved since the engagement portion of the frame is engaged by the locking pins, unlike the prior art which is adapted to mesh the teeth on a reel shaft with the teeth on a frame.  Accordingly, the reel shaft is assuredly locked against turning in the seat belt pulling direction, as a result of which reliability is enhanced.

Title: Foam analyzing method and apparatus
Inventor: CONSTANT MARC D
IPC: G01N33/14
Filed: 1992-11-16
Abstract: A method of analyzing the visually perceptible characteristics of foamable liquid, such as beer, comprises pouring a known quantity of the foamable liquid from a storage container into a clear beaker.

Patent CA-2083585-A1 (CA)
IPC: B67D7/36
Filed: 1992-11-23
Abstract: A tank-filling drop tube assembly (2, 48) includes a drop tube (16, 50) and a linear motion shut-off valve assembly (24).  One embodiment includes a barrier (30) which seals the interior of the drop tube.  Outlet ports (32) are formed through the drop tube above the barrier. A restrictor sleeve (26, 58) is mounted around the outside of the drop tube just below the outlet ports.  The restrictor sleeve is connected to a float (36) at the upper end (10) of the drop tube.  When the tank (4) is substantially filled, the float lifts the restrictor sleeve to seal the outlet ports to help prevent overfilling of the tank.  In an alternative embodiment, the shut-off valve assembly (80) includes a liquid level sensing floating valve element (90, 110) mounted within the interior (78, 106) of the drop tube.  When the liquid level within the tank reaches the valve element, the valve element begins floating until it blocks liquid flow through the drop tube. Thus, in this embodiment, the float acts as both the float and the valve element which seals off the drop tube.

Abstract: ABSTRACT            A TRAINABLE AUTOMATED IMAGE CYTOMETRY DEVICE FOR FULLY AUTOMATED SEARCH OF DESIRABLE OBJECTS            An apparatus and a method for training an automated image cytometer consists of acquiring in focus images of individual objects, analyzing the features of each object and recording the resulting data in a storage medium.  An operator then identifies a selection of images which are to be treated as being of the same class.  A computer then performs multivariate analysis on the features of the identified images and uses the results to identify other potential members of the class.  The apparatus may be further trained by displaying the potential members of the class and having the operator identify those members which are not properly within the class.  Further multivariate analysis is then performed to refine the class identification.

Title: Spatial/frequency hybrid video coding facilitating the derivation of variable-resolution images
Inventor: PURI ATUL
IPC: H04N7/50
Filed: 1993-06-09
Abstract: An adaptive technique for video encoding and decoding which facilitates the transmission, reception, storage, or retrieval of a scalable video signal.  The invention allows this scaling to be performed in both the spatial and frequency domains.  In a specific embodiment of the invention, video encoding is adaptively performed based upon a selection from among a multiplicity of compatible spatial-domain predictions from previously decoded images, and a selection of compatible predictions obtained from up-sampling decoded lower resolution images.  The decoded lower resolution images correspond to a current temporal reference, and at least one of  these lower resolution images is encoded in more than one frequency domain scales.  In yet another embodiment of the invention, one lower resolution signal is encoded (without reference to any other low resolution signal) by employing the MPEG-1 standard, with a modified partitioning of  the resultant bistream into two or more frequency scale bitstreams.  The decoded images from these bitstreams are employed in the spatial prediction of a higher resolution layers.

Abstract: An electrode structure (100) for an addressing structure using an ionizable gaseous medium has a substrate (102) and a cover (126). A plurality of channel-defining portions (116, 118, 120, 122, 124) each extend from the substrate to the cover; each pair of adjacent channel-defining portions defines a plasma discharge channel (129, 131, 133, 135, 137) for the ionizable gaseous medium. An electrode (104, 106, 108, 110, 112) extends through each channel-defining portion so that the electrode has a surface exposed to each of the channels defined in part by the channel-defining portion.      Each of the channel defining portions or walls separates each electrode from the cover. An addressing structure using the electrode structure of the invention ionizes the gas in each channel by driving the electrodes of the pair of adjacent channel-defining portions that define the channel.

Title: Dual status thin-film eas marker
Inventor: TSAI CHING-LONG
IPC: H01F10/12
Filed: 1993-11-22
Abstract: A dual status marker for use with a magnetic-type EAS system has a signal-producing layer including at least one magnetic thin-film of high permeability and low coercive force such as permalloy, and a signal-blocking layer including at least one remanently magnetizable thin-film such as an Fe-Cr alloy. The remanently magnetizable thin-film or thin-films should have a total thickness at least equal to, and preferably at least twice, the total thickness of the magnetic thin-film or thin-films of high permeability.      By doing so, the marker is more reliably deactivated when the signal-blocking layer is magnetized. For even greater assurance of deactivation, the signal-blocking layer should include more than one remanently magnetizable thin-film, thus giving it a squarer B-H loop and greater assurance against false alarms.
