Abstract: A warning device for displaying information in a vehicle, particularly a motor vehicle, the warning device having a display of the information presented as a virtual image in a visible region of the windshield of the vehicle. In order to make certain that a warning information is transmitted with great persistence to the party to be warned, the invention provides that the information be mirrored into the windshield on a larger scale within increasing intensity of warning.

Abstract: A shift register is disclosed in which an n-stage shift-register chain (sr) consists of 2n series-connected, like basic cells (zi) which are driven in antiphase by a first and a second shift clock (C1, C2) from a clock generator (g). The nonoverlap range of the two shift clocks is temperature- and frequency-stable, so that the shift register can be used within a wide frequency and temperature range. Frequency adaptation is accomplished simply by changing resistance values.

Abstract: A parallel analog to digital converter and a method of processing at least two independnet signals therein are disclosed in accordance with the teachings of the present invention. The analog to digital converter has an improved sample and hold stage which, in addition to quantizing the analog signals, also multiplexes them. The sample and hold stage comprises at least two differential amplifier circuits, a latch stage, and a timing stage. Each differential amplifier circuit converts one analog input by comparing it to a reference voltage. The discrete output of the differential amplifier circuit is stored in the latch stage and outputted to an encoder. The timing circuit stage first selects one differential amplifier circuit to output its discrete signal, and then selects the latch stage to output its stored results. By sequencing through each differential amplifier circuit, the present invention effectively multiplexes the analog inputs.

Ambient light can pass through the display panel from the side away from the observer to the side towards the observer. On this side of the display panel away from the observer there is arranged a background surface, the projection of the contour of the display panel from the observer onto the background surface being smaller than the background surface as seen from the perspective of the observer.

The base-emitter pn junctions of the transistor structures are so connected in series with respect to the direction of the total current flowing during operation that some of them are operated in the reverse direction up to the breakdown region as zener diodes and the remainder in the forward direction as forward bias diodes. The emitter of the first transistor structure acting as a zener diode or the base of a transistor structure acting as a forward bias diode, as well as the collector of the latter transistor structure, are connected to the first external terminal. The emitter of the latter transistor structure, acting as a forward bias diode, is connected to the second external terminal.
