A pattern generator includes a control unit, an address generation unit, and a data memory unit. The control unit has a plurality of control memories for storing information of the scanning order of addresses, the control unit outputting an address in accordance with the information stored in the control memories. The address generation unit has a plurality of address control memories for storing information used for controlling to generate addresses, the address control memories being provided ...

There is provided a pattern generator which is capable of utilizing memory blocks connected to unused pins of a DUT. A pattern address from a vector generation control 1 and a control signal from a control table buffer 2 are used to control an address converter 9 to convert a pattern address PA into plural-bit addresses a, b and c. The address a or b is provided to m memory blocks 10 (m being an integral multiple of the number n of pins of the DUT) to generate therefrom pattern data. The pieces ...

Input values are digitally represented and the bits used to address memories. A composite (e.g. the sum) of the memory outputs is formed, and update control is used during "learning" to modify the memory contents. The digital representation is formed by an encoder which encodes input values using a redundant code, which preferably has a Hamming distance to signal distance relationship which has a relatively steep initial slope and is closer to being monotonic than is the relationship for a simpl...

A patterned sample is analyzed by traversing a light spot across the sample and analyzing detected color at several sites to spatially resolve the pattern. A pattern analyzer includes a holder for supporting the sample which is illuminated by projecting the light spot onto the sample. A color sensor receives light reflected by the sample at the light spot and analyzes color of the sample at the spot. The spot is traversed across the sample surface to obtain a plurality of color readings across t...

Pattern recognition apparatus uses a recognition processor for processing an input signal to indicate its similarity to allowed sequences of reference patterns to be recognised. A speech recognition processor includes a classification arrangement to identify a sequence of patterns corresponding to said input signal and for repeatedly partitioning the input signal into a speech-containing portion and, preceding and/or following said speech-containing portion, noise or silence portions. A noise mo...

A pattern making and pattern drafting system is disclosed. The system has a pattern group, stored in memory, consisting of a plurality of patterns having prescribed base lines and base points. Commands are executed to perform prescribed processing on a reference pattern and are stored into memory, the thus stored commands then being reproduced sequentially on at least one object pattern other than the reference pattern. In reproducing a command, the target point to be processed and the amount of...

In a map with a pattern of folding lines along which the map can be folded, it is easy to find geographical regions shown on the map due to two portions connected via a common center area and each having a plurality of folding lines in equidistant portions in a direction parallel to two parallel limiting lines, the map being folded on successive lines alternatingly in opposite directions so as to form a plurality of flaps.

A surface pattern (1) has N visually recognizable patterns which are composed of optically diffractive, microscopically fine relief structures, plane mirror faces or absorbing or scattering structures. The N patterns share at least one independent common surface element (11). The surface element (11) is subdivided into surface parts and has an arrangement of the surface parts which is independent of the N patterns, which has a predetermined structure, and which is not recognizable to the naked e...

A surface pattern comprises microscopically fine relief structures that diffract visible light. When the surface pattern is illuminated perpendicularly with white light, the surface pattern appears with bright and dark regions from a first viewing direction. The length and/or position and/or number of bright and dark regions changes as the viewing angle changes. Preferably, the contour of the surface pattern is selected so that the length or position of the bright regions changes markedly when t...

In a circular knitting machine, needle selection is controlled by pattern keys mounted on a pivoted pattern key carrier and having patterning butts which are selectively engageable with vertically stacked selector slides. The selector slides are engageable selectively with selector butts on pressers associated with needle jacks. When a presser is engaged by a selector slide the corresponding jack is pressed in so that a control butt on the jack is not engaged by a needle-operating cam. Pivoting ...
