Abstract: An adjusting device for positioning a load comprises a spindle and a spindle nut which is arranged on the spindle. Either the spindle nut is supported in a gear housing so as to be rotatable and not axially displaceable and the spindle is axially adjustable by rotating the spindle nut for positioning the load, or the spindle is supported in the gear housing so as to be rotatable and not axially displaceable and the spindle nut is axially adjustable by rotating the spindle for positioning the load. The gear housing has blind holes on two oppositely located housing sides and the swivel bearing bushes are pressed into these blind holes for receiving swivel pins.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An electronic releasing device for pyrotechnic igniters has a primary and a secondary charge. The primary charge is ignited by means of a circuit that comprises electronic components and whose essential electronic components are accommodated as an integrated components as an integrated circuit in an IC housing, with the housing being disposed on a printed circuit board. The terminals of the IC housing are provided as connecting points for test instruments for checking the serviceability of the integrated circuit and the igniter function and also serve for connection to external electronic devices for programming the releasing device.

Abstract: A chair, in particular an office chair, comprises a pedestal; a seat support propped thereon; a seat supporting itself on the seat support; a backrest support mounted on the seat support; a headrest support mounted on the backrest support; and a headrest mounted on the headrest support and having a height setting mechanism for height adjustment of the headrest and an inclination setting mechanism for adjustment of an angle of inclination a of the headrest.

Abstract: The invention relates to trigger units for initiating pyrotechnic elements which usually consist of a switch and control unit, ignition means and an ignition charge body. Said switch and control element is triggered by way of an electric coupling via a line in order to initiate ignition. The line for the electric coupling and the dimensions of the switch and control element which are usually accommodated in an IC housing complicate the design and the automatic assembly of the trigger units. According to the invention, the switch and control element (1) is surrounded by a first shell (2). Said first shell (2) is connected to a second shell (1) which contains the ignition charge body (23). The invention is further characterized in that the ignition means (19) dip into said second shell (21).

Abstract: A method is provided for protecting stored-program control systems, in particular in motor vehicles, which offers a software protection system for programming. A programming routine for programming by an external device is subdivided into segments in such a way that queries for programming authorization can be accomplished between the individual segments.

Abstract: 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.

Abstract: A device for the recording, storing and outputting of data of a control unit in a motor vehicle, besides the operating time of the control unit, makes it possible for other data to be acquired and stored as well, so that information will be provided regarding the probability of failure or the future reliability of the control unit. Noteworthy as these additional data is at least one of the quantities:maximum control-unit temperatureduration of a control-unit temperature above a certain valueminimum control-unit temperatureduration of a control-unit temperature below a certain valuemaximum value of the voltage on the supply-voltage linelength of time a supply voltage is applied above a certain valueduration and intensity of interference voltages on control-unit lines.

Abstract: A digital control unit, in particular an ignition and/or injection control unit for motor vehicles, is provided. The control unit has a microcomputer (10) and a permanently connected main storage (12) containing control data and operating programs. This main storage unit (12) is designed as a read/write memory (RAM, EEPROM or the like). A control program that runs when the control unit is switched on is provided in an auxiliary storage (13) designed as a permanent storage (ROM, EPROM or the like). Based on a load instruction, the control program controls the loading of the main storage (12) from an external storage medium via an interface (21). The control program also automatically transfers the operating program access of the microcomputer (10) to the main storage (12). In this manner, software modifications can easily be subsequently implemented in the control unit when, for example, improvements or variations in program data or characteristic data are available and desired.
