Abstract: In order to operate a motor vehicle, a position sensor and a radiation source as well as at least one vital sensor having a detector are provided. The position sensor delivers a measurement signal having information regarding a predetermined area of the vehicle interior of the motor vehicle. The radiation source emits a predetermined radiation after activation. The vital sensor detects a reflected portion of the radiation that is emitted by the radiation source. The measurement signal of the vital sensor is representative of at least one vital parameter of a given vehicle occupant. As a function of the measurement signal of the position sensor, a position is determined of at least one predetermined reference body part of the vehicle occupant in question. The orientation of the radiation source is controlled as a function of the detected position of the predetermined reference body part of the vehicle occupant in question.

Abstract: A graphic character that has a character matrix with a number of character units that are indivisible at least in either a horizontal direction or a vertical direction is scaled by dividing the character matrix into one first and at least one second character segment, each comprising at least one of the character units. The first character segment is symmetrically scaled using a first scaling factor and the second character segment is scaled using a second scaling factor different from the first scaling factor.

Abstract: A circuit configuration of an integratable and controllable ring oscillator for generating a clock signal includes first and second stages being connected between supply terminals and having input and output terminals. The output terminal of the first stage is connected to the input terminal of the second stage. An inverter is connected between the output terminal of the second stage and the input terminal of the first stage. The input terminal of the second stage supplies a clock signal. Each of the stages includes first and second transistors having load paths connected between the supply terminals in a series circuit with a connecting point between the transistors. The second transistor has a gate terminal connected to the input terminal. The first transistor determines the frequency of the clock signal, is controllable in accordance with a control variable and acts as a current source. A capacitor has one terminal connected to the connecting point and another terminal connected to a fixed potential.

Abstract: A data slicer circuit for separating and recovering digital teletext signals from a demodulated composite color signal derives the slicing level by using a framing code detector and a gating pulse having an active phase during horizontal and color sync pulses. By an adder or a multiplier, a start value is formed at the beginning of each picture line. A square wave reference signal is formed which is subtracted from the start value containing composite color signal. From the difference signal, a digital automatic control system forms the slicing level.

Abstract: With this correcting method, errors in bytes are corrected successively. To this end, the signal resulting from the parity check is stored into a page memory, along with the character bits of each byte. The parity check signal replaces the parity bit of each byte. Two successively received identical pages are stored together with their parity check bits into first and second segments of the page memory. The two pages are compared for equality of the character bits and parity check bits. The result of the comparison is evaluated as follows.

Abstract: A delay circuit provides adjustable delay in constant increments. In order to achieve adjustable but constant delay times of a chain of inverter pairs, each pair is completed by a capacitor, a third inverter, and a transfer transistor the gate of which is fed by a voltage controlling the pair delay time. This voltage is generated by a control circuit measuring the actual delay time of the chain with respect to the period of a constant clock signal.
