The invention relates to a method and a device for sintering objects by means of time-resolved detection of two- or three-dimensional surface profiles and, optionally, by means of temperature measurement in a high temperature furnace on the basis of optical measurement methods. During sintering, each surface point on an object can be measured for its position and, optionally, its temperature, and a change can be determined by successive measurements. The measured change additionally permits control of the sintering regime. The method comprises the steps of: placing an objectinto a high temperature furnace; heating the furnace; generating a two- or three-dimensional surface profile at least of a subregion of the objectby: irradiating the objectwith light from a light source; detecting the light scattered by the objectwith the aid of a detector; determining the geometric surface profile from the detected light.

In a correction method for a microprocessor-controlled digital regulation of a drive motor, wherein the measurement arrangement used for the regulation of the motor is simplified. recognizing that the real value surveying cannot always be implemented periodically by the microprocessor at the requested point in time, making sporadic measurement errors of a simplified measurement arrangement ineffectual, in accordance with the method individual measurement values with a sudden change are read out and correction values are used instead of these for the regulation.

In a method and arrangement for manipulation of the contents of a data memory with which a processing device can be connected to manipulate (in at least one manipulation step at least one first memory range of the data memory, the processing device monitors a monitoring range of the first memory range, the state progression of which allowing the conclusion of the manipulation of the first memory range to be detected. A processing device with a buffer is used, into which buffer the data are read from the data memory. A sub-range of the data memory is established as a first exclusion range of the data memory. The first exclusion range not being read into the buffer. The first exclusion range is established in an establishing step preceding the manipulation step. The exclusion range includes the monitoring range.
