Title: Wind-direction sensor
Inventor: NICKEL HEINZ ING GRAD
IPC: G01P13/02
Filed: 1981-07-14
Abstract: In a wind-direction sensor (1), use is made of a single-turn potentiometer (5) having a closed resistance track (5') in the form of a circle, whose movable tapping element (4) is actuated as a function of position by a wind vane (2). The single-turn potentiometer (5) is fed from a constant- (stabiliser-) voltage source (6) via two feed-in points (N, S) offset by 180 DEG  relative to one another. A voltage (U) proportional to the position of the wind vane in the wind rose is tapped between one of the feed-in points (N or S) and the movable tapping element (4), and fed to a first output (A1) of the sensor (1). While respectively sweeping over one feed-in point (N or S), a bistable switching device (8) coupled to the movable tapping element (4) changes its switching state, which can be tapped at a second output (A2) of the sensor (1) as a binary switching signal and effects a changeover of the display range in the evaluation of the measurement signal picked off at the first output (A1). The sensor is used in automatic weather stations. <IMAGE>

Filed: 1982-02-13
Abstract: The application relates to a circuit arrangement with an MOS circuit for exchanging the dial switch of a subscriber telephone station in which the contacts of the hook switch are located between the dial pulse contact and the normally-open dial contact. As shown in Figure 2, the connections (2, 4) which lead to the contacts of the hook switch are connected to a hook-switch sensor which responds to the voltage via the contacts of the hook switch and which acts on the connection of an electronic dial pulse contact (nsi). A relay changeover contact is disposed between the connections (1, 3), each of which is connected to a respective wire of the exchange line, which contact is applied to the connection (3) of the circuit arrangement while the dialling operation is in progress, to which connection one wire (b) of the exchange line and one end of the speech circuit are connected. If the hook switch is opened during the dialling operation, the loop current continues to flow through the circuit arrangement until a delay period elapses, at the end of which the relay changeover contact (ris) is returned to the speech setting shown and the loop current is interrupted so that only a small permissible reverse current flows via the hook switch sensor to feed a semiconductor memory located in the MOS circuit. <IMAGE>

Patent DE-3242551-A1 (DE)
Title: Arrangement for identifying an object
Inventor: GOETTING JUN HANS-HEINRICH ING
IPC: G06K7/00
Filed: 1982-11-18
Abstract: The invention relates to an arrangement for identifying an object and for determining the distance, for example of a vehicle, machine part or of a location on a roadway. An identification device radiates energy via a transmitting antenna. A code carrier on the object receives this energy via a receiving antenna and converts it into operating energy. The code carrier activates a code memory. The code is read out and the receiving antenna is thereby loaded. This connection leads to a field change at the transmitting antenna of the identification device, and thus to a modulation. The modulation can be filtered out, amplified and evaluated. The degree of modulation is a measure of the distance between the identification device and code carrier. In a special embodiment, the code memory content can be overwritten. The arrangement operates reliably free of maintenance with very little expenditure. <IMAGE>
