Abstract: A processing device embodied in an integrated circuit may be divided into first and second functional units. A mount for the integrated circuit may be assigned to the first functional unit, which may define the external electrical connections of the processing device. Processing may take place in a second functional unit of the processing device, whose essential connections may normally be accessible from outside via the external connections of the first functional unit. The processor device having first and second functional units in a mount may be similar to a hybrid circuit but may serve a different purpose. The first functional unit, which may also comprise more than one monolithic integrated circuit, may define the external connections and may make available suitable matching circuits for the second functional unit.

Abstract: A mount for a programmable electronic processing device is disclosed. It is divided into at least a first functional unit (7) and a second functional unit (8) which represent separate, particularly monolithic integrated, components. The first functional unit (7) defines all input and output interfaces of the processing device with respect to their electrical properties. All essential connections of the second functional unit (8) are accessible from outside only via the first functional unit (7). To this end, the first functional unit (7) includes matching circuits which serve to electrically adapt the connections of the second functional unit (8) to the external conditions.

Abstract: An iterative interpolator permits linear interpolation between a first known value and second known value, which are defined by n-coordinate values in an n-dimensional coordinate system. An intermediate value to be interpolated is defined by n-1 intermediate values. By an interval nesting process in a first coordinate direction, an approximate value is formed for the first intermediate value. A copying device transfers this interval nesting process to the required coordinate value in the other coordinate direction.

Abstract: A master-slave data transmission system employs a flexible single-wire bus and where any master unit can send data to or read data from any slave at a single time. Data transfer is accomplished by means of a flexible message format having a variable-length address section and a variable-length data section, with the beginning and end of the individual message sections being defined by labels, and a fixed bit clock being transmitted for a given interval before and/or after the message. During multiple master operation, a priority control arrangement prevents two or more masters from accessing the single-wire bus at the same time.

Abstract: A floating data interface, particularly for integrated circuits, is formed by a Hall-effect arrangement that includes a Hall-voltage-measuring device and a current-carrying coupling loop whose current is controlled by a data source. Because of the low internal resistance of the coupling loop, a plurality of such interfaces can be connected in series, and the individual circuits selected by addresses. Bidirectional data transfer via the floating interface is accomplished by an interrupter stage which interrupts the current flow on the bus line in an interrogation interval during one clock period and forces a predetermined mark/space ratio.

Abstract: A zoom system for enlarging a portion of a video image chosen on a display screen by a cursor wherein the cursor is controlled by a remote position-dependent transmitter. An electrooptical arrangement receives positional signals from the remote transmitter causing the cursor to move on the display screen in relation to the movement of the remote transmitter. The cursor is used to select a portion of the displayed video image to be enlarged. Once chosen by the cursor, the selected portion of the video image is enlarged in a zoom circuit and shown on the display screen in place and stead of the original image.

Abstract: A remote-control system with position control includes a spread-spectrum where at least three independent spread-spectrum signals are transmitted. At the receiving end, these signals are separated into their individual components by means of at least three correlators and form the diode signals. Synchronizing means at the receiving end, including further correlators, synchronize the received spread-spectrum signals with associated reference signals with the aid of a phase-locked loop and a control unit.

Abstract: A projection television system includes a projection unit having an optical element through which infrared television signals are received. The received signals are processed to provide a television image display which is projected for viewing. Received television signals from a TV station or cable are converted to infrared signals and transmitted along a given axis of an infrared transmission link extending between an infrared transmitter, remotely positioned from the projection unit, to an infrared detector, located in the projection unit. The detector converts the infrared TV signal into a video signal which signal is processed by the projection receiver to provide the image for display. The infrared transmitter, the optical element and the detector are aligned along a given axis which is also the optical axis of the system.

Abstract: A system for remotely controlling a television receiver has a position-dependant transmitter and an electrooptical arrangement which controls the motion of a cursor on a television screen. The electrooptical arrangement also generates menu entries to facilitate the selection of functions for tuning and operating the television receiver. The menu entries are selected by means of the cursor. The electrooptical arrangement includes adaptive filters which stabilize the position of the cursor on the screen and thereby allow for an increased number of control functions to be implemented.

Abstract: A digital control circuit with a device for generating a high-resolution tuning voltage is suitable for use in receivers for RF signals, particularly in consumer equipment. The tuning voltage can be electronically switched from one value to another at a high speed. The transient time required with conventional control loops is nearly eliminated since the low-pass filter or the digital integrator is preset to its steady-state integration value. To generate the tuning voltage, dynamic digital-to-analog convertors are provided which, despite their high resolution, require only a smoothing filter with a short response time and a short time constant.

Abstract: In an electrooptical arrangement for remotely controlling an electronic apparatus with a remote control transmitter, the transmitter is formed with three sources of radiation whose radiation patterns are different from each other and can be comparatively detected relative to each other to indicate the tilting of the transmitter in different reference plane directions. A radiation detector at the receiver side detects the different radiation intensities for the signals from the three sources, and the relation between the signal intensities is evaluated to determine the tilt angles of the remote control transmitter in the reference plane directions.
