Patent DE-4140911-A1 (DE)
Inventor: SCHULTE WOLFGANG
IPC: H04N13/307
Filed: 1991-12-12
Abstract: A projector has an essentially afocal projection system, in particular for reproducing three-dimensional images. This system has a system of convex lenses arranged on the side of the object and a Fresnel lens (2) arranged on the side of the image. The lenses are larger than the transverse dimensions of the object to be reproduced. By providing a double reflection (3, 4), this projection system is enabled to generate, besides the usual two-dimensional images, a three-dimensional image ''positioned in space'' of a three-dimensional object whose sides are correctly perceived by an observer. Preferably, a plane mirror (3) is used for that purpose, as well as a beam splitter (4) which is inclined by about 45 DEG  in relation to the main axis (5) of the system of convex lenses (1).

Title: Method, circuit and measurement pickup for detecting physical quantities by selective measurement of electrical quantities of the response signal
Inventor: ZWOSTA HELGE DIPL ING
IPC: G01D5/246
Filed: 1993-07-21
Abstract: The method causes a sequence of defined input signals to be applied to electrical components with dynamic behaviour. The response signals are determined by the physical parameters influencing such an electrical component with dynamic behaviour. It is possible to use characteristic quantities of the response signal for determining physical measurement quantities. Such characteristic quantities can be, among others, time or level values. It is also possible to cover dynamic measurement quantities by a sequence of input signals with the corresponding speed. The method described thus causes the electrical components with dynamic behaviour to function as measurement pickups. The structural design of these measurement pickups then determines their field of application and the measuring range. Thus, an inductive coil can be used as position, angle or distance pickup. A system of two conductive plates can be constructed as position, angle or force pickup. The type of electrical circuit into which a measurement pickup of the above type is connected then determines the type of input or response signals. That is to say the circuit arrangement determines, for example, whether step functions are input as input signals to a measurement pickup and whether a characteristic time or a characteristic level of the response signal is evaluated.

Title: Current measuring circuit using temp. sensors

IPC: G01R19/03
Filed: 1993-10-28
Abstract: The current to be measured is supplied to a first resistor (1) which includes a first temp. sensor (3) responsive to the temp. of the resistor. Amplifiers (4, 7) produce an output representative of the difference between the output of the first temp. sensor (3) and the output of a second temp. sensor (5) responsive to the temp. of a second resistor (6).The output of the amplifier (7) is connected to a square root unit (8), which provides a voltage that is representative of the square root of the difference between the first output and second output signals across the second resistor (6) and to a processor (9) that calculates the current through the first resistor (1) from the voltage across the second resistor (6). The square root unit avoids the problem of long setting times for low current values and instability at high currents.
