Patent EP-0329129-A2 (EP)
Inventor: TURNER PAUL
IPC: G07F17/24
Filed: 1989-02-16
Abstract: A parking meter reset device includes an infra-red radiation transmitter element slidably positioned within a transmitter module and an infra-red radiation detector element positioned within a cavity in a detector module. The modules are within a housing adapted for mounting on a parking meter pole so that the detector element is directed downwardly from 5° to 10° below horizontal and the transmitter element is directed downwardly at an angle about 5° less than the downward angle of the detector element. This minimizes detection of stray radiation such as from sunlight. An edge of a first window, positioned in front of the transmitter module, abuts an edge of a second window, in front of the detector module. A portion of the radiation transmitted into the first window is refracted through the abutting edges into the second window. If either window is blocked, refracted radiation causes the parking meter to function like a non-resetting meter. The transmitter and receiver circuitry draws power only during brief pulses ocurring at greater intervals, minimizing power requirements.

IPC: H04B3/44
Filed: 1989-02-20
Abstract: In a connection line with digital information transmission, where the voltage poles and the power-consuming units are connected in each case at the mid-points of transformers terminating the connection lines, it is to be ensured that partial currents of equal strength flow in each case through the individual connection wires. To achieve this, a control network is in each case connected in series to the windings of a transformer which are applied to a connection line, which network adjusts the strength of the partial currents flowing through the individual wires to exactly identical values. The control networks ensure that the partial currents flowing in opposite directions in the transformer windings cancel one another so completely that no magnetisation of the transformer core can take place. Any impairment of transmission quality which this might produce is thus prevented. <IMAGE>
