Title: Motion estimation and compensation of video object planes for interlaced digital video
Inventor: EIFRIG ROBERT O
IPC: H04N7/50
Filed: 1998-02-25
Abstract: A motion estimation and compensation technique is provided for interlaced digital video such as video object planes (VOPs). Predictor motion vectors for use in differentially encoding a current field coded macroblock (700) are obtained using the median of motion vectors (MV1, MV2, MV3) of surrounding blocks or macroblocks (712, 722, 732). When a surrounding macroblock (820) is itself interlaced coded, an average motion vector for that macroblock is used, with fractional pixel values being mapped to the half-pixel. When the current block (912) is not interlaced coded but a surrounding block (820) is, the field motion vectors may be used individually or averaged.   In a repetitive padding technique for an interlaced coded VOP (1,010), the even (0, 2, ..., 14) and odd (1, 3, ..., 15) lines of the VOP and surrounding block (1,000) are grouped.  Within each field (1,210, 1,220), exterior pixels (1,6) are padded by setting them to the value of the nearest boundary pixel (0,6), or to an average of two boundary pixels (0,6; 1,7).  The lines are then reordered to provide a single padded reference VOP image.

Title: Balloon for a dilation catheter and method for manufacturing a balloon
Inventor: ROUCHER LEO R JR
IPC: B29C49/18
Filed: 1998-04-23
Abstract: A method for forming a balloon for a dilation catheter is provided herein. The method includes the steps of: (i) positioning a tube in a preconditioned mold; (ii) expanding the tube in a preconditioned mold to form a parison; (iii) positioning the parison in a balloon mold; and (iv) expanding the parison within the balloon mold to form the balloon. Thus, the tube is initially expanded into a parison in the preconditioned mold. Subsequently, the parison is expanded into a balloon in the balloon mold. Because of this unique manufacturing process, polyester block copolymers can be formed into balloons. Some of these polyester block copolymers could not be formed into a balloon using prior art blow molding processes. The resulting balloon exhibits superior characteristics, including relatively thin and consistent walls, soft texture, low uninflated crossing profile, expansion in a predictable fashion, and good tensile strength.

Abstract: Une unité de double vitrage isolante et une unité de double vitrage à vide classiques n'ont pas une propriété isolante suffisante et il convient d'augmenter l'épaisseur d'une unité isolante/de double vitrage afin d'améliorer la propriété isolante. L'unité isolante/de double vitrage de cette invention comprend une première unité de double vitrage à vide (2) dotée de deux plaques de verre plat (3 et 4) dont les périphéries sont hermétiques, entre lesquelles sont pris en sandwich des éléments d'espacement (5) multicouches et dont la partie intermédiaire est rendue vide, ainsi qu'une seconde unité de double vitrage à vide (2) ou un verre plat ordinaire (10) dont la périphérie est rendue hermétique par un agent d'étanchéité (12), et laquelle est stratifiée sur la première unité de double vitrage à vide (2) avec un espace intermédiaire. Etant donné que de l'air sec ou un gaz rare est enfermé hermétiquement entre ces deux plaques de verre plat, on peut améliorer la propriété isolante sans augmenter l'épaisseur globale de l'unité de double vitrage isolante.

Abstract: An adapter is disclosed which allows the secure installation of a lighting fixture to a lighting track and which lies flush with the face of the track in its locked condition. The lighting fixture can be locked in a desired horizontal and vertical orientation by the operation of a single actuator arm. Rotation of the actuator arm from an unlocked to a locked position causes two friction plates to come into engagement, thereby to establish a braking action that prevents further movement of the lighting fixture in the vertical direction, and also moves a pair of clamps into operative engagement with the lighting fixture, thereby to limit its horizontal rotation.

Patent CA-2253297-A1 (CA)
Inventor: DREWS MICHAEL D
IPC: G06T15/50
Filed: 1997-04-30
Abstract: An adaptive pixel multisampler (24) generates pixel data for display using an interlocking sub-pixel sampling pattern P and a frame buffer (26) organized as a per-polygon, per-pixel heap (64). The interlocking sampling pattern P provides the advantages of a multi-pixel shaped filter without pixel-to-pixel cross communication and without additional sub-pixels. The per-polygon, perpixel heap (64) allocates frame buffer memory so that each pixel will have one set of data stored in the frame buffer (26) for every polygon that influences that pixel. This memory allocation scheme can significantly reduce frame buffer memory requirements. The polygon data is blended to properly handle processing of transparent polygons and polygon edges without the degradation of image quality found in conventional computer graphics systems.

Title: Joint quantization of speech parameters
Inventor: HARDWICK JOHN CLARK
IPC: G10L19/02
Filed: 1998-11-23
Abstract: Speech is encoded into a frame of bits.  A speech signal is digitized into a sequence of digital speech samples that are then divided into a sequence of subframes.  A set of model parameters is estimated for each subframe.  The model parameters include a set of voicing metrics that represent voicing information for the subframe.  Two or more subframes from the sequence of subframes are designated as corresponding to a frame. The voicing metrics from the subframes within the frame jointly quantized.  The joint quantization includes forming predicted voicing information from the quantized voicing information from the previous frame, computing the residual parameters as the difference between the voicing information and the predicted voicing information, combining the residual parameters from both of the subframes within the frame, and quantizing the combined residual parameters into a set of encoded voicing information bits which are included in the frame of bits.  A similar technique is used to encode fundamental frequency information.
