摘要:
An arrangement for positioning an X-ray machine, with an input and an output device, for interactive control, with a memory region, in which digitised X-ray images and X-ray machine data are stored, an interface, by means of which information is exchanged with the X-ray machine, a pointing device for selecting regions in digitized X-ray images, a processing unit, which carries out calculations based on the digitized X-ray images, the associated X-ray machine data and the selected region, in order to determine control data such that the X-ray machine is controlled whereby, on taking an image, the selected region is screened.
摘要:
A method and device for identifying objects, especially teeth, on a digitized X-ray picture, by using image processing algorithms to localize areas containing the object by segmenting and/or edge detection, these areas being computationally linked with parameters of the X-ray unit and, optionally, with patient-heightened specific parameters. Another method and device for assigning information to objects, especially teeth, determined in a digitized X-ray picture or in a schematic representation, includes a first step detecting the digitized X-ray image for the schematic representation, a second step in which a determination of objects manually or automatically ensues in the event these objects have not yet been determined, a third step selecting the object for which additional information should be stored, retrieved or deleted, and a fourth step in which a reference that is stored is followed for a query operation to determine the information displayed by using such reference.
摘要:
A method of announcing an apparatus to a system containing a central apparatus and at least one individual apparatus is distinguished in that the announcement is effected by optical communication, preferably in the infrared range. In that respective information about the apparatuses in the system is stored in the central apparatus.

A centrifuge has a bucket for receiving the product to be centrifuged, and a support which is configured to be inserted in the bucket and receive microtiter plates and the like. The support has substantial stability and comprises a generally planar base and four upstanding lateral walls which are integrally formed with the base and which are coupled together at their upper edges to form a substantially self-contained enclosure.

The invention relates to a system for determining a sensor holder for holding an object, whereby the sensor holder carries a digital sensor of a dental X-ray unit. The inventive system comprises an input and display unit for interactively controlling the same, whereby a schema image can be displayed on the display unit. The system also comprises a processing unit that, based on the selected sensor holder, simulatively generates the schema image from which is apparent which area of the object is displayed when using the selected sensor holder.
摘要:
A microcomputer (10) is proposed, which includes a central processing unit (11), a non-volatile memory (13), a volatile memory (14), a monitoring circuit (12) and also an input/output unit (16). Two different operating states are possible in the microcomputer (10). In the first operating state, the microcomputer executes a program which is located in the non-volatile memory (13). In the second operating state, the microcomputer (10) executes a program which is located in the volatile memory (14). The monitoring circuit (12) effects a resetting of the microcomputer (10) whenever it does not receive a monitoring signal for a predetermined time (watchdog timer). The microcomputer is distinguished in that it includes an element for suppressing monitoring signals which are always active whenever the microcomputer (10) is operating in the second operating state.

摘要:
An input circuit for an HF-transmitting component 1 of a battery-operated device for the transmission of a data signal aims to reduce the power consumption. For that purpose the fundamental frequency of a reference oscillator 5 is modulated with the digital data signal, the data rate being greater than 20 kchip/s. For smoothing of the modulated reference signal an amplitude limiter 11 and a band pass filter 15 are connected between the reference oscillator 5 and the HF-transmitting component 1.
