摘要:
An MPEG video decompression method and apparatus utilizing a plurality of stages interconnected by a two-wire interface arranged as a pipeline processing machine. Control tokens and DATA Tokens pass over the single two-wire interface for carrying both control and in token format. A token decode circuit is positioned in certain of the stages for recognizing certain of the tokens as control tokens pertinent to that stage and for passing unrecognized control tokens along the pipeline. Reconfiguration processing circuits are positioned in select stages and are responsive to a recognized control token for reconfiguring such stages to handle an identified DATA Token. A wide variety of unique supporting subsystems circuitry and processing techniques are disclosed for implementing the system, including memory addressing, transforming data using a common processing block, time synchronization, asynchronous swing buffering, storing of video information, a parallel Huffman decoder, and the like.

A method and apparatus are described for cleaving a relatively thin semiconductor wafer for inspecting a target feature on a workface thereof by: producing, on a first lateral face of the semiconductor wafer, laterally of the workface on one side of the target feature, an indentation in alignment with the target feature; and inducing by impact, in a second lateral face of the semiconductor wafer, laterally of the workface on the opposite side of the target feature, a shock wave substantially in alignment with the target feature and the indentation on the first lateral face, to split the semiconductor wafer along a cleavage plane essentially coinciding with the target feature and the indentation.

Material transparent at infra red wavelengths, 3-5 and 8-14 .mu.m is formed of ZrN, YN, CeN, TLN, or EuN. The material can be used as a self supporting material or as a coating on substrates such as infra red transparent material e.g. Ge, ZnS, ZnSe, As.sub.2 S.sub.3, As.sub.2 Se.sub.3, optically transparent materials e.g. sodium glass, or reflecting surfaces such as metal surfaces, e.g. Al or silvered surfaces. For some substrates e.g. Ge a thin, e.g. 10-1,000 Angstrom bonding layer may be used to improve adhesion. Bonding layers may be Ge, Si, Ge.sub.x C.sub.1-x, Si.sub.x C.sub.1-x (0
摘要:
The invention relates to an insect trap (10), which mimics certain characteristics of a mammal and comprises a housing comprising a base (22) and a cover (24). The pad generates an infrared heat source (14) and can also generate water vapour (16). The trap has an insect retention surface (18) and is characterized in that the cover is positioned over the base in a manner such that it defines an opening (50) around the base/cover interface (52). The opening has a depth (d) of less than 1.5 cm and is sized and positioned such that at least one attractant signal (14′, 16′) is directed out of the opening in a manner allowing effective operation for at least 8 hours.

Providing an ion beam; and directing and at least twice deflecting the provided ion beam, for forming a directed multi-deflected ion beam, wherein the directed multi-deflected ion beam is directed towards, incident and impinges upon, and mills, a surface of the work piece. Device includes an ion beam source assembly; and an ion beam directing and multi-deflecting assembly, for directing and at least twice deflecting the provided ion beam, for forming a directed multi-deflected ion beam, wherein the directed multi-deflected ion beam is directed towards, incident and impinges upon, and mills, a surface of the work piece.
摘要:
A memory interface for connecting a bus to memory comprises an input, a buffer, an address input, a generator, and a writer. The input receives a plurality of data words from the bus. The buffer buffers the data words received from the bus. The address input receives from the bus addresses associated with the plurality of data words. The generator generates a series of addresses in the memory into which the buffered data words may be written. The series of addresses are derived from the received addresses. The writer writes the buffered data words into the memory at the generated addresses.

A transducer assembly adapted for the pulse-emission of a signal includes a transducer (10) with a drive-circuit (20) therefor. The drive circuit (20) includes a charge-storage device (21), a wound-coil device (23) and one or more switching-elements (24, 25). The assembly can be used to determine the level of a fluid in an enclosed vessel.
