Patent EP-0319787-A2 (EP)
Inventor: EVANGELISTI CARLO JOHN
IPC: G06T15/50
Filed: 1988-11-24
Abstract: The present invention comprises a method for utilizing an socalled SIMD computer architecture in conjunction with a host processor and coordinate processor to render quality, three-dimensional, anti-aliased shaded color images into the frame buffer of a video display system. The method includes a parallel algorithm for rendering an important graphic primitive for accomplishing the production of a smoothly shaded color three-dimensional triangle with anti-aliased edges. By taking advantage of the SIMD architecture and said parallel algorithm, the very time consuming pixel by pixel computations are broken down for parallel execution. A single coordinate processor computes and transmits an overall triangle record which is essentially the same for all blocks of pixels within a given bounding box which box in turn surrounds each triangle. The individual pixel data is produced by a group of M x N pixel processors and stored in the frame buffer in a series of repetitive steps wherein each step corresponds to the processing of an M x N block of pixels within the bounding box of the triangle. Thus, each pixel processor performs the same operation, modifying its computations in accordance with triangle data received from the coordinate processor and positional data unique to its own sequential connectivity to the frame buffer, thus allowing parallel access to the frame buffer.

Filed: 1988-04-05
Abstract: A method of manufacturing a semiconductor device is described in which gaseous material is supplied into a reaction chamber containing a substrate to cause a first epitaxial layer of a first material to grow on the substrate and switching means are then operated to alter within a predetermined period the supply of gaseous material into the reaction chamber to cause a second eitaxial layer of a second material to grow on the first layer. During the predetermined period a radiant heat source is activated to radiantly heat the surface of the first layer so as to smooth the first layer on an atomic level before growth of the second layer is commenced. The radiant heat source may be a laser capable of directing one or more laser pulses at the surface to be radiantly heated.

Abstract: An expandable collapsible product is made by providing a pleated sheet (8,10) having legs (20) which are made by securing two parts of a fold (17) together. Two sheets are combined by securing the end of a leg (20) to a crease (16) or a leg (20) of an opposite sheet. The sheet material can be folded to provide alternating taller folds (17) and shorter folds (16), and the taller folds are modified to provide the legs (20) by glueing parts of the taller folds (17) together. Glueing can be accomplished by moving glue heads across the sheet at high velocity through the use of linear motors. The glue lines may be heated after being laid down by the use of electro-magnetic radiation, preferably from a high-powered laser. The finished product may be used as insulated window coverings, or the like.

Title: Modulator/demodulator apparatus
Inventor: CUMMISKEY PETER
IPC: H04B3/23
Filed: 1989-04-28
Abstract: A modulator/demodulator apparatus has a first digital signal processor (DSP1) that is operable in a full duplex mode for providing digital samples to a coder-decoder (IOP) and receiving transmitted samples therefrom. The first digital signal processor (DSP1) is responsive to received samples for initiating echo cancellation in the received samples. A second digital signal processor (DSP2) is operable to demodulate samples received from the first digital signal processor and output demodulated information therefrom. An input/output processor (IOP) initiates operation of the first and second digital signal processor. The input/output processor receives input information to be transmitted and supplies that information to the first digital signal processor and receives demodulated message information from the second digital signal processor and outputs message information to one or more user devices. The input/output processor also receives transmitter digital samples which are to be demodulated from the first digital signal processor and supplies the transmitted samples to be demodulated to the second digital signal processor. The input/output processor as operable in a full duplex mode. 
     Accordingly the input/output processor acts as a system controller in controlling transmission and reception digital signal processors which provide independent transmission and reception functions suitable for a multirate modem apparatus.

Abstract: A counter comprises a series of hollow digit-displaying drums (13-17), with mechanical driving connections (18 - 21) driving succeeding drums so that a decimal total number is set up. The higher significance digit drums (14 - 17) each carry an optical encoder comprising a cylindrical surface with slots forming a binary code which is related to the displayed digit. U-section reading devices (30 - 33) straddle the encoder to read the code and produce an electrical coded output. 
     To avoid problems caused by readings at changeover points, the lowest significance digit-displaying drum (13) is associated with an impulse drive which is triggered at each changeover point to drive the drum forward so that it does not come to rest at the changeover point. The impulse drive comprises an off-centre weight which rotates with the drum.

Abstract: An automatic wire bonding apparatus, for wedge-bonding using aluminium wire, comprises a bonding head comprising a bonding tool mounted on an ultrasonic transducer, a bonding tip of the tool being arranged, in the operation of the machine, to press aluminium wire against the contact surface of an electronic or electrical component, the wire being drawn from a suitable wire supply, and a wire clamp by which the wire drawn from the wire supply may be clamped, the wire clamp being movable backward and forward generally in the direction in which the wire is fed appropriately to position the free end of wire drawn from the spool after completion of a bonding operation. The automatic wire-bonding apparatus further comprises means for monitoring, during bonding, the quality of the bond formed between the wire and the surface to which it is to be bonded, by identifying those bonds which do not fall within predetermined maximum and minimum values for deformation of the wire due to ultrasonic excitation. By using the automatic wire bonding apparatus described, the time during which ultrasonic energy is transmitted to the bond is minimised, thus maximising the throughput of the machine, and wastage due to unsatisfactory bond formation is reduced.

Abstract: In a drive for a punch-side ejector slideably mounted in a ram of a mechanical forming press and having a bent lever which is swivellably mounted in the ram and one leg of which acts on the ejector end facing away from the punch and the other leg of which is acted upon by a cyclically driven control cam and is held in contact with the latter, the object is to make possible free adjustability of the motion characteristic of the ejector by as simple means as possible. The solution consists in the fact that the control cam (23) is provided on a control slide (9) which is displaceable in a guide fixed to the frame, parallel to the direction of motion of the ram (6), and on which there engages, in a bearing, a control connecting rod (8) which, at the other end, is mounted eccentrically on a shaft also serving for driving the ram (6).

Abstract: Television signals are currently still mainly reproduced by means of cathode ray tubes. Newly developed reproduction devices with a flat screen have as a rule a matrix with picture elements which are selected in dependence on the received television signals. The matrix arrangement selection system is designed in such a manner that a particular display control circuit is only suitable for one television standard. So that video signals of different scanning standards can also be reproduced on reproduction devices having a matrix-shaped display device, the video signal is temporarily stored in the reproduction device, and before reproduction occurs, digital signal processing is carried out by means of vertical reinterpolation. The circuit arrangement according to the invention is particularly suitable for standards conversion of video signals for representation on a reproduction device with matrix display device. <IMAGE>
