1417 results about "Data preparation" patented technology

Data preparation is the act of manipulating (or pre-processing) raw data (which may come from disparate data sources) into a form that can readily and accurately be analysed, e.g. for business purposes.

Method and arrangement for control of the printing of a thermotransfer printing device

In a method and an arrangement for controlling printing by a thermotransfer printing apparatus with relative movement between a thermotransfer print head and a print medium, a microprocessor that provides pixel energy data to a pixel energy memory by making an energy value calculation and by coding, and a print data controller prepares the pixel energy data by decoding during the printing in a number (corresponding to the pixel energy value) of binary pixel data each with the same binary value. The print data controller includes at least one pixel energy data preparation unit, a DMA controller, an address generator, a printer controller and a phase counter. The DMA controller allows an access to the pixel energy data stored in the pixel energy memory as code in order to provide the pixel energy data in print columns to the at least one pixel energy data preparation unit. The address generator generates addresses for selection of the buffered code during each phase of a number of phases. The phase counter supplies a phase count value to a phase data preparation unit in which the code value A and phase count value B are compared in order to generated binary pixel data, which are serially supplied from the output D to at least one shift register of the thermotransfer print head.

Communication navigation system

A communication navigation system, wherein a navigation apparatus requests a recommended route guidance data to a information center and guides a user of the navigation apparatus to a destination by using the recommended route guidance data received from the information center.In this present invention, the navigation apparatus transmits version data of road data held in the navigation apparatus at the request to the information center. The information center prepares a guidance data of recommended route using latest road data held in the information center, and transmits the data to the navigation apparatus. When the information center transmits the guidance data, the information center selects the type of data of the road links along the recommended route, in the guidance data, by comparing the version data received from the navigation apparatus and the version data of each road link along the recommended route. If each data of road links along the recommended route is considered to be contained in the road data held in the navigation apparatus, the information center transmits the only data which enable to specify the road link from the road data held in the navigation apparatus. On the hand, if each data of road links is considered not to be contained in the road data held in the navigation apparatus, the information center transmits whole data of the road link. Therefore, the navigation apparatus can generate the route guidance data by extracting road link data, from its own road data, corresponding to the road link specified by transmitted data and by reconstructing road link data using transmitted data.

Position ensuring system for oblique machining in five-axis machine tool

There is provided a position ensuring system for oblique machining in a five-axis machine tool which, based on the inclination and the direction of an inclined hole to be machined, carries out measurement of an error in the pivot angle of a spindle head and an error in the rotation angle of a table before initiating machining of the hole, and can automatically correct the pivot angle of the spindle head and the rotation angle of the table upon machining of the hole, thereby precisely ensuring the position of the spindle head and the position of the table in the machining.
The position ensuring system includes: an A-axis calibration means for measuring a displacement angle, which is an error between a target value and a measured value of the pivot angle of the spindle head about the A-axis as the spindle head is pivoted to meet the inclination angle of an inclined hole to be machined in a workpiece, and correcting the pivot angle about the A-axis in such a manner that the displacement angle as measured with the corrected pivot angle as a target value fall within a tolerable range, before initiating machining of the workpiece, the measurement of displacement angle being carried out for all the inclined holes to be machined by execution of a measurement program prepared based on data on the shapes, including the inclination angles and the directions, of the inclined holes to be machined; a corrected data storage means for storing the corrected pivot angle about the A-axis for each of the inclined holes to be machined; and an A-axis control means for reading out the corrected pivot angle about the A-axis for each inclined hole upon executing a machining program for the workpiece by means of an NC apparatus, and instructing the corrected pivot angle about the A-axis to pivot the spindle head when executing oblique machining of the inclined hole.
