Abstract: Shock absorber device for roller skates, particularly but not exclusively of the type with aligned wheels, the skates including the body of the shoe (11) wherein the foot and part of the user's leg fit, the shoe (11) being connected to a support (12) on which are mounted the elements (13) which run on the ground, the connection between the shoe (11) and the support (12) being of the articulated type (14), the device comprising an elastic foil element (21,121,221,321) shaped with at least an inverted angle and associated, at least at the ends, respectively with the shoe (11) and the support (12) at a point at a distance from the articulated connection (14).

Abstract: A method and an extractor for pressing out plasma and buffy coat from a collapsible blood container (1), in which blood has been divided, by centrifugation, into a plasma layer, a buffy coat layer and a layer of red blood cells. The plasma and then the buffy coat are pressed out each through a separate outlet tube (2) or through a common outlet tube (2), which is connected to the top portion of the blood container, a pulsating pressure being applied to a top section of the blood container (1) during the end phase of the pressing-out of buffy coat. The extractor has a stationary support surface (6) and a movable pressing member (7), between which the blood container is suspended and subjected to a compressive force in order to press out the plasma and then the buffy coat through the outlet tube (2).

Abstract: A hose with a protector comprises: a tubular-shaped hose body 10; a tubular-shaped protector 20 which is coaxially provided in the state in which it covers the outer peripheral surface of the hose body 10; a tubular-shaped engager 30 which bonds the hose body 10 and the protector 20 integrally at both edge portions thereof and which forms an inserting opening into which a nipple is inserted and bonded. By producing the hose body out of resin and producing the protector out of rubber, the present hose with a protector can obtain heat resistance and anti flame resistance which are suitable for a filler hose and which are necessary at the time of vehicle fire and also the present hose with a protector is good in sealing property with the mating pipe and good in connecting function.

Abstract: A non-contacting type radio frequency recognizing credit card system is disclosed. In the conventional credit card system, the card recognition is carried out by contactingly inserting a credit card (40) into a card reader which is connected to a card managing company. Therefore, the card may be damaged, and the card recognition time is extended.

Abstract: The invention provides a life-jacket which takes account of the articulation zones of a wearer's body, namely those parts of the upper torso that bend, twist and flex when engaged in maritime activities. This is done by providing a life-jacket having buoyancy material with articulation zones in it which are coincident with a wearer's articulation zone. One particularly suitable form of life-jacket may incorporate a sailing trousers. The life-jacket (1) has an upper body garment which has seven front pockets (10, 11, 12 and 13) on each side of a front opening (4), namely lower pockets (10 intermediate pockets (11), chest pockets (12) and a shoulder pocket (13) defining a waist articulation zone (20), an underneath ribs articulation zone (21), a mid-ribs to armpit articulation zone (22), a below collar bone to a top of the shoulder articulation zone (24). Each pocket contains suitable buoyancy material. Further pockets are placed on the back of the life-jacket (1).

Abstract: A video signal is coded by intraframe coding. The coded video signal is then decoded by intraframe/field decoding. A decoded local video signal is generated, which corresponds to a specific region in one frame of a video signal coded one frame prior to the video signal. A first motion signal is generated, which indicates motion of pictures in both the decoded video signal and the decoded local video signal. The motion signal is then subtracted from the video signal to generate a predictive error signal which is then coded by intraframe coding. The coded video signal and the coded predictive error signal are decoded by intraframe/field-decoding. A second motion signal is generated, which indicates motion of pictures in both the decoded video signal and a video signal decoded one frame prior to a video signal to be reproduced. The decoded predictive error signal and the second motion signal are added to each other to reproduce the video signal.

Abstract: A video data editor edits video data which has been predictive-coded between pictures. An editing controller outputs number data for specifying video data to be read from a recording medium and editing point data indicative of editing points of the video data to be read. The video the outputted number data. The read video data is decoded to obtain reproduced pictures. The reproduced pictures are coded to obtain re-coded video data. Before and after the editing points, original coded video data is switched to the re-coded video data on the basis of the editing point data. In stead of the editing point data, video processing control data indicative of types of video processing for editing can be used. With the video processing control data, when judged that the video processing is proceeding, original coded video data is switched to the re-coded video data, before, during and after the video processing.

Abstract: An adaptive polarization cancellation arrangement which nulls out all types of concurrent interference signals received by a Global Positioning System (GPS) receiver from antenna mainlobe and sidelobe situated sources. The orthogonally polarized components of the composite received signal are separated by the receive antenna arrangement and adjusted in the polarization feed adapter network between the antenna and GPS receiver to optimally cancel components. The antenna and installation arrangement creates a polarization filter relative to interference sources which changes their apparent polarization orientation and supports adaptive discrimination based on dissimilar polarization characteristics relative to the desired signals. The orthogonal received signal components from the GPS satellite constellation and from interference sources are combined to adaptively create cross-polarization nulls that adequately attenuate interference sources while slightly modifying the GPS received signals.
