Title: Impact zone detection device
Inventor: PARK KYUNG T
IPC: F41J5/04
Filed: 1989-11-29
Abstract: IMPACT ZONE DETECTION DEVICE  Abstract of the Disclosure A device for determining which zone on a target has been struck by an object.  The device is made of a frame, and a flexible support means which is mounted on the frame, and  is  disposed  in  the  path  of  a  moving  object.    A transducer  made  of  piezoelectric  film,  coated  with  a conductive  coating  on  each  of  its  surfaces  to  form electrodes, is mounted on the flexible surface. Attached to  the  electrodes  of  the  transducer  are  leads  which transmit electrical pulses to a signal processing unit.  An object striking the target produces an electrical pulse which is translated by the signal processing unit and which determines the zone on the target which was struck by the object.

Inventor: LU SHIH-LAI
IPC: B32B3/30
Filed: 1990-02-09
Abstract: A microstructure-bearing composite plastic article can be superior, both in microstructure and in physical properties, when it is a composite of a tough, flexible substrate, at a surface of which is microstructure formed of a cured oligomeric resin having hard segments and soft segments, which cured resin is substantially confined to the microstructure portion of the composite. Such a composite plastic article can be made by depositing an uncured oligomeric resin composition onto a master negative molding surface in an amount barely sufficient to fill the cavities of the master, filling the cavities by moving a bead of the composition between a substrate and the master, and curing the deposited composition by ultraviolet radiation while keeping the temperature during curing to not more than 50°C above the typical use temperature of the finished composite plastic article.

Abstract: TECHNIQUE FOR INFORMATION PROTECTION ON FAULT-TOLERANT REDUNDANT INFORMATION             STORAGE DEVICES Abstract The present invention relates to a technique which provides swift and easy error correction and detection on one or more fault-tolerant redundant storage devices. In the present technique, an information packet including (a) the destined storage location identifier in a first section, (b) the information in a second section, and (e) a unique monotonically increasing number in a third section, is sent by a processor to one or more redundant storage device controllers for storage in relative locations of the redundant storage device(s), where the monotonically increasingnumber is incremented and applied to each sequential information packet to be stored on the redundant storage device(s). When relative storage locations of the redundant storage device(s) are subsequently read and the information is found not to match, an error has occurred on one of the storage device(s), and if the storage location identifier on the compared information packets are also found not to match, then the information packet including the correct storage location identifier is used However, if the storage location identifiers are found to match, then the compared information packet with the higher monotonically increasing number is deemed to contain the correct information.

Title: Multi-port valveless pump
Inventor: PINKERTON DENNIS
IPC: F04B13/00
Filed: 1990-12-27
Abstract: A valveless, positive displacement metering pump is provided which is capable of either mixing two or more fluids or dividing a fluid from an inflow line into two or more outflow lines.  The pump includes a housing which contains a cylindrical working chamber at different radial positions.  Three or more passages extend through the housing and communicate with the working chamber.  A piston is positioned within the working chamber.  The piston includes a duct defined by its outer surface which communicates with one of the passages, depending upon its rotational position.  The piston is rotated as it is driven back and forth within the cylinder, thereby causing the duct to sequentially communicate with the passages and the piston to sequentially close the passages.  Depending upon the axial direction of movement of the piston, fluid is either pumped into or out of the working chamber as the duct rotates into communication with one of the passages.

Title: Machine for sorting plastic bottles as a function of their plastic composition in order to recycle the same
Inventor: MORIN ANDRE
IPC: B07C5/34
Filed: 1990-12-20
Abstract: ABSTRACT OF THE DISCLOSURE             An apparatus and a method are disclosed, for use to sort objects such as bottles, made of different transparent or translucent plastic materials according to the kind of plastic material of which these objects are made. The method consists in producing a beam of U.V. light and subjecting each object to be sorted to this beam in a detection zone, and detecting the intensity of the beam transmitted by the object at different wavelengths selected within a range encompassing the "cut-off wavelengths" of the different plastic materials to be sorted, the cut-off wavelength being the wavelength known per se and specific to each plastic material, above which the coefficient of light transmission through the plastic material, dramatically increases. By comparing with each other the values of the intensity detected at said different wavelengths, one can determine the cut-off wavelength of the plastic material of which the object subjected to the beam is made, and thus identify this plastic material. This method makes it possible to  industrially recycle reject objects made of different plastic materials, which has proved to be very difficult to do up to now.

Inventor: MASERA LORENZO
IPC: H04N19/00
Filed: 1991-03-01
Abstract: A video signal coding system allows still and moving picture components of a motion video transmission to be coded using the same algorithm.  A posteriori recognition of still pictures is performed and the quantization steps used to code groups of pixels of a still picture which belong to a certain hierarchial level (e.g. the macroblock level) are memorised and used in producing convergence of the  quantization  step  utilized  towards  a  minimum predetermined value.  This operation permits the bit rate required to transmit still pictures to be reduced, or the resolution with which such a picture is transmitted to be increased.
