摘要:
A method for calibrating a device for non-contact position measurement wherein a movable part subject to positional identification is provided spatially proximate to a sensor carrier that includes a plurality of signal generators electrically and spatially separated from one another in order that the position of the moving part can be identified via voltage signals therefrom. To obtain an unequivocal characteristic of the positional voltage distribution, only defined signals such as a zero value signal or other characteristic value, have length values signed to them and neighboring voltage values are coemployed to obtain an unequivocal position identification.

Contact-free cards that have at least two coupling elements spatially separated from one another such as, inductor coils, capacitors plates or photoreceivers, that utilize the effects derived from the spatial distance of the coupling elements from one another, i.e. stereo effect, is provided. The contact-free chip cards use the stereo effect to decide whether they are located within a prescribed range of a transmitter receiver. The range of the access can be reduced further, but cannot be increased beyond a fixed limit. Thus, access to the data of such cards outside this range is precluded. Such cards can additionally be equipped with means for switchable authorization of remote access. The contact-free card apparatus of the present invention further provides that it is the card itself and not the card environment that decides whether it is located in the near range of the terminal device such that it allows protectable access to its data and prohibits access from a greater distance.

An apparatus for bidirectional data transmission includes a predominantly stationary part with a data line connected to cause a phase shift of an osicllator signal for transmission to a predominantly mobile part. AC signal components of the oscillator signal received by the mobile part are formed into square wave pulses and a difference between high and low states of the pulses is indicative of a phase shift. During the high and low states, positive signal edges of a second oscillation frequency are counted and compared to one another so that predetermined difference causes a status change on a data output line in the mobile part.

In a system having a mobile part and an immobile part between which data and energy are transmitted, an electronic control for two resonant circuits serve the purpose of transmitting energy to the mobile part. The resonant circuits are driven so that their oscillations have a prescribed phase shift relative to one another. For data transmission to the mobile part, a phase shift is superimposed on the transmitted signal at one resonant circuit. On the basis of the phase relation of the signals relative to one another, the mobile part can identify which resonant circuit is transmitting the data. The oscillation of the resonant circuit that is transmitting new data via the phase shift is used for the formation of the clock signal on the part of the mobile part.

Methods and devices are described with which screen displays, screen contents and screen layouts, for instance, job searches, are all available to users of competence functions (competence profiles) depending on the occurrence of certain types of data in databases. By means of the methods and devices, such screen displays, screen contents and screen layouts of job searches can be generated in the form of competence functions (competence profiles) depending on the occurrence of certain types of data in databases. It is likewise described how suitable search profiles can be found with competence functions and how suitable competence profiles can be found with search profiles.
摘要:
A process for dispensing individual chip cards to a plurality of individual chip card users employs a chip card dispensing station (1) with at least one storage container (2). Chip cards are stored in the chip card dispensing station (1). The chip cards are capable for use in external read-write stations and contain electronic components requested by a card user for implementing chip card applications. A remotely located verification or monitoring station (5) is linked to the chip card dispensing station (1) via a cable-linked and/or radio-linked active data connection (4) for entering personal data into the chip card dispensing station via a user menu (3). A loaded chip card is issued to the card user operating the user menu. The loaded chip card is selected from the chip cards stored the chip card dispensing station (1).
