Title: Playback method and apparatus for reproducing encoded data in a reverse playback operation
Inventor: KAWAMURA MAKOTO
IPC: H04N7/50
Filed: 1996-01-30
Granted: 2006-12-12
Abstract: Encoded data is reversely reproduced by decoding each picture only once and using only as many frame memory sections as are needed in a normal playback operation. A picture header detector detects a picture header from data read out from a video code buffer to identify the type of picture. The picture type information controls a picture data selecting circuit for selecting frames of I and P pictures equal in number to the number of frame memory sections in a frame memory bank. The selected frames are supplied to an inverse VLC circuit to be decoded, starting at the head of a GOP with an I picture. The decoded I and P pictures are stored in the frame memory bank and transmitted to a display unit, starting with the temporally most recent picture and reading backward.

Granted: 2008-03-18
Abstract: A high bending strength and high density material for osteosynthesis, which comprises a biodegradable and bioabsorbable crystalline thermoplastic polymer material, and a high strength implant material, comprising a composite material in which a bioceramics powder of from 0.2 to 50 .mu.m in particle size is dispersed in the polymer material, wherein crystals of the polymer material are pressure--oriented not in a uni-axial direction but basically in parallel with a plurality of reference axes; and a production method by pressure orientation, which comprises preparing in advance a biodegradable and bioabsorbable crystalline thermoplastic polymer material or a dispersed mixture of the polymer material and a bioceramics powder and melt-molding it into a pre-molded material which is then press-charged at a cold temperature into a cavity of a closed type forming mold, thereby obtaining an oriented molding. Since the osteosynthesis and implant materials are dense and high strength oriented moldings having less anisotropy in which crystals are oriented in parallel with a plurality of reference axes, excellent ideal biomaterials can be provided which have appropriate hydrolysis property, can maintain sufficient strength during a period required for bone union and are degraded and absorbed atsuch a rate that they do not induce inflammatory reactions after healing of the fractured bones so that re-operation is not required.

Title: Radio frequency ion source
Inventor: LANGFORD MARIAN LESLEY
IPC: H01J27/16
Filed: 1995-12-14
Granted: 2006-02-21
Abstract: An rf ion source suitable for low power operation over a range of pressures in air comprises discharge electrodes having one or more cathodes (1) and an anode (2). Each cathode (1) is connected to an rf signal supply (8) through an associat ed coupling means (4) and the anode (2) is adapted to provide a surface area over which a plasma discharge may occur that is not substantially greater than the total cathoda l area over which the discharge may occur. In this way the anode (2) presents no more useful surface than is required to accommodate the optimum area of the plasma discharge thereby preventing plasma wander and enhancing the stability of the discharg e over known ion sources. By configuring the electrodes such that the respective areas of the anode and the cathode(s) over which discharge occurs are separated by no mor e than 5 mm and by forming the electrodes to have highly curved ends and so creating a higly distorted electric field in the inter-electrode gap when the source is in operation, it is possible to create an effective discharge with very low power input even at atmospheric pressure.

Granted: 2003-12-02
Abstract: The present invention is a food package comprising, in combination, a tray, a collar, and an anchor to resist slideable displacement of the collar relative to the tray. The tray has a plurality of open top food compartments, and, in plan view, is substantially rectangular with a top planar surface defining perimeter edges about the tray and borders between top openings of the compartments. Each compartment has bottom and side surfaces, the bottom surfaces lying substantially in a bottom plane parallel to the top surface of the tray, the sides of adjacent compartments being separated by predetermined spaces. The collar surrounds the tray over the top surface, about a first perimeter edge of the top surface, covering the sides and bottom surfaces of at least a portion of two adjacent compartments and about a second perimeter edge opposite to the first perimeter edge. The anchor is pressed from the collar into a space between the sides of two adjacent compartments to resist slideable displacement of the collar relative to the tray. In a preferred embodiment of this invention the collar also has an integral stand to support the package upright on it's edge with the top surface in a substantially vertical plane. For example, in an embodiment where the collar begins as a strip which is wrapped about the tray, the strip ends may overlap at the joint with an outside end extending from the joint to form a tab. The joint may be placed close to the perimeter of the bottom plane so that the extending tab can act with the corresponding edge of the top surface to support the package upright on its edge.

Title: Multiple mode digital x-ray imaging system
Inventor: SHAPIRO EDWARD G
IPC: H04N5/217
Filed: 1997-11-26
Granted: 2002-04-23
Abstract: A multiple mode digital X-ray imaging system providing for preprocessing "binning" of analog pixel signals from a detector array by selectively summing, within the detector array, adjacent pixel charges on a row-by-row basis and selectively summing, within detector array readout circuits, the previously summed pixel charges (by rows) on a column-by-column basis. An array, or mapping, of "defective pixel" flags is used to identify defective pixels within the detector array, with such flags being added to, or inserted into, the incoming data stream for dynamic processing along with the incoming pixel data. A  buffer and filter is used to perform still image capture during the radiographic mode of operation and to recursively filter incoming data frames during the fluoroscopic mode of operation by summing a scaled amount of pixel data from prior data frames with a scaled amount of incoming pixel data from the present data frame.
