Abstract: An element which can be plugged into an electronic data processing (EDP) device, for receiving a user card which is equipped with components, including at least one of a processor and/or data memory, a frame having an exterior form, which is designed to accommodate the user card, a first interface for transferring data between the element and the EDP device, and a second interface formed by contacts on the user card and on the frame, for transferring data to and from the user card. The exterior form of the frame is that of a diskette so that it can be inserted into a diskette station of an EDP device. The first interface between the element and the EDP device is designed in a standard fashion, so that data can be transferred using a standard read/write device already present in the diskette station of the EDP device.

Abstract: A pocket interface unit for a smart diskette. The smart diskette has a housing of the shape and size of a standard diskette, electrical contacts and/or a magnetic transducer, an activation switch, and further has an interface, a processor and memory disposed in the housing and operatively coupled to the electrical contacts/magnetic transducer.

Abstract: An insertable device, for use with electronic data processing equipment data transfer units, e.g., disk drives or cassette units. The device includes a housing for insertion into the electronic data processing equipment data transfer unit designed to fit the data transfer unit, an interface disposed in the housing for facilitating the transfer of data between the device and the electronic data processing equipment, and a processor disposed in the housing and operatively connected to the interface, for performing processing of data.

The first interface between the element and the EDP device is designed in a standard fashion, so that data can be transferred using a standard read/write device already present in the diskette station of the EDP device. The frame carries a battery for supplying current via the interface to the components located on the card, and carries an additional processor and data memory for providing the element with additional processor and storage capacity.

Abstract: An insertable element for the diskette or cassette station of a piece of electronic data processing equipment having an interface. The arrangement is such that data transmission between the EDP equipment and the element can be carried out through write/read devices which already exist in the EDP equipment. The element has a component which, in the inserted condition, is outside of the EDP equipment and itself is comprised of the EDP components and/or of the EDP devices and/or is constructed as a device to connect further EDP devices. According to another feature, a process for operating the EDP device with this insertable element is carried in such a way that the entire PC operating system and further programs are stored and at the commencement are loaded from there.

Abstract: A system for the exchange of data between a transfer device and an "intelligent insertable object" that comprises an electronic memory associated with an access circuit and emulates a magnetic recording support with respect to a magnetic read/write head of the transfer device, the data exchange bit rate of the transfer device being greater than that of the circuit providing access to the memory of the insertable object, the system comprising means to limit the bit rate of useful elements in the apparent bit rate of data elements entering and leaving the transfer device, so that it is compatible with the bit rate leaving and entering the circuit providing access to the memory of the insertable object. The system can be applied notably to the exchange of data elements between a microcomputer and an electronic card that can be inserted into the disk drive of the microcomputer or into a memory card reader.
