A system for the electronic control of a multi-system machine, or for the manufacture of control strips for textile machines containing a storage system for color lines which are obtained by scanning a multi color design pattern and which contain in series form information about a given color of a standard design, and a storage unit inserted after the storage system for the continuous control of each system by step-wise read-out of the stored color lines, the system having the improvement of a storage system having storage means with variable information content during continuous machine operation whereby a number of color lines corresponding at least to the number of systems is storable and where each stored color line may be exchanged for a new one after processing of its information and a displacement means for generating the displacement of the storage lines so as to alter the sequence of each color line as a function of the machine.
A process for preparing discrimination criteria for color identification comprises reading values representing a plurality of color components delivered from a color sensor for each of a plurality of given reference colors, calculating relative values of the color components, calculating relative values of the color components, calculating the deviation of the relative value of each color component from a specified value, extracting pairs of deviations each having a discrimination distance of at least specified times relative to any other reference color, determining a discrimination criterion between the extracted pair of deviation, and repeating the extracting and determining steps by calculating deviations of higher order with use of the deviations until discrimination criteria are determined for all the given reference colors.
Apparatus for the electronic control of a knitting machine of the type comprising a storage device having an information store in which the information of a knitting pattern is stored in block form with every information block containing all the information for one course. The information blocks are broken down into color lines related to the particular colors being knitted, and a distributor mechanism is arranged to feed the color lines to the storage units of a working store, the storage units being associated with respective knitting systems of the knitting machine. The distributor mechanism includes a programming mechanism in the form of a selector matrix controlled by a cross-bar distributor and which determines which knitting system will receive the information for any information block selected from the storage device.
The toroidal computer memory system utilizes toroidal memory paths in its chitecture to enable memory locations along those paths to be obtained in a single access, as compared to multiple accesses typically required by conventional linear computer memory. The storage/retrievable media is designed to replicate paths on the surface of a torus. By defining certain parameters and the mathematical properties of these memory paths in the electronics of a controller, points on the memory paths can be accessed from the storage/retrieval media more efficiently than conventional computer memory.
In an orthophotograph recorder, a three dimensional optical model of a terrain produced by a stereo pair of aerial transparencies is projected onto an imaging plate. The optical model is scanned by an optically produced reference point while the height of the viewing plate is manually adjusted by the operator to maintain the reference on the apparent ground level of the terrain. The scanning motion of the reference point, as well as the height of the imaging plate, is digitally encoded and formatted into data blocks. Each block of digital data represents an individual scan line on the optical model, and is characterized by a starting coordinate and incremental coordinate data. This data format minimizes storage requirements and permits editing of individual scan lines. The encoded data are scaled and stored on magnetic tape to be used to control exposure of a photosensitive sheet in an orthophotograph printer. The printer comprises a light projector located above a platen carrying the photosensitive sheet. A transparency corresponding to the optical model is located between the projector and platen. Adjacent the photosensitive sheet, there is a screen containing an aperture which is moved parallel to the platen to expose the photosensitive sheet to the projected optical model in scanning fashion. During scanning, the height of the platen is adjusted in accordance with the stored digital data so that the sheet portion being exposed is always kept in intersection with the apparent ground plane of the optical model.
A home knitting machine is provided with electronic control means which function pursuant to patterning instructions on a program card and in response to the operation of control devices by an operator causing needle actuators on the carriage of the machine to be selectively operated and fabric knitted in a prescribed manner on the machine.
