An arrangement which has a panel-like electrical/electronic module, such as a solar power module, and a connection unit which are electrically connected to one another. The module and the connection unit each have an essentially flat printed conductor structure with connecting sections. The printed conductor structures are situated in parallel planes. The connecting sections are rigid electrical conductor sections and are bent out from the planes of the printed conductor structures of the connection unit and the module. The connecting sections of the connection unit are situated corresponding to the arrangement of the connecting sections of the module so that for the connection unit connected to the module each connecting section of the module is electrically connected to a respective connecting section of the connection unit and these adjoin one another in one section situated in a different spatial position than that of the planes of the printed conductor structures.

Assembly comprised of a panel-like constructed module and of a connection unit, production method and device

System for monitoring and controlling the opening and closing of

A method and apparatus for operating and monitoring the opening and closing cycle of electrically operated units such as electric windows and electric slide roofs which both eliminates the danger of body parts getting caught in the window and permits a complete opening and closing of the window automatically. In accordance with the invention, the speed of the drive motor is measured, directly or indirectly, and the first obtained measured value is compared with all following measured values. More particularly, this first measured value is used to detect momentary electrical and mechanical factors which change over the entire time of operation of the window, such as self-heating of the drive motor, the voltage charge of the battery, and the state and condition of the window. The processing or comparing of the measured values is carried out by a microcomputer. The actual measuring of the speed is by means of a sensor. The changes furnished by those sensors are utilized to determine the position of the window. This recognition of the position makes it possible in case of danger, to safely turn off the drive motor and possibly to open the window again. Further still, in a normal case, the window may be closed completely.

An electrical circuit for controlling the operating of the relay of a fuel pump depending on the number of revolutions of the motor supplied by the fuel pump, whereby the fuel pump is cut off if the minimally permissible time interval being ignition pulses falls short, i.e., the number of revolutions of the motor exceeds an established value.

Circuit arrangement for monitoring an electricity-consuming load fed with direct current one terminal of which is grounded, particularly for monitoring an incandescent of an automotive vehicle, and the circuit arrangement being installable without interfering with the existing network of lines or cutting conductors. Between the switch of the load and the current-consuming device a measurement coil is arranged parallel to a conductor within the magnetic field produced by the flow of electricity through the conductor, the input of the coil being connected to a voltage supply source and its output being connected in a Schmitt trigger circuit with the non-inverting input of a differential amplifier constituted as operational amplifier and the output of the amplifier being fed back via a resistor to the non-inverting input and being connected to a fault indicator.

A method for the coded data transmission in half-duplex operation between data terminal devices of two data stations employs a code device of the one data station to transmit a phase-in program to the code device of the other data station. Thereby, the code devices of the two data stations communicate via corresponding data transmission devices in full-duplex operation. After phase-in of crypto units of the two data stations in one direction, change of direction programs, data and end identifications are transmitted, and in the opposite direction, simultaneously, synchronizing signals are transmitted.

An electrical circuit providing a light passing signal function obtained by means of a single push switch independently of whether the low beam switch is open or closed. An electronic system controlled by the push switch and the low beam switch is provided for controlling the high beam contact of the relay and when the low beam is disconnected the electronic system closes the relay contact as a function of the length of time of the closure of the push switch and when the low beam is connected the relay contact is also closed as a function of the length of time of the closure of the push switch.

Automotive vehicle switching electric circuit

A precision resistor for use in electrical circuits arranged on printed circuit boards is produced from a band of thermally conductive alloy. The band is selectively surface treated with a conductive coating to improve solderability in the region of the resistor where it is connected to conductors of the circuit board.

Device for resetting a direction-of-travel indicator for automobiles after completing a curve providing in association with the turnable steering-column/steering-wheel unit and in fixed position thereto switch elements, particularly opto-electrical transmitters and receivers coverable by a mask turnable with the steering-column/steering-wheel unit which when the steering wheel is turned back after going around a curve disconnects the directional indicator which has been actuated by a push switch and a scanning of the direction of rotation takes place. The device is characterized by a digital evaluation electronic system which satisfies a series of sequential conditions.

An opto-electronical switching device provided with an operating push-button key, particularly for motor vehicles, comprises a housing, containing a photodiode and a phototransistor, a rectangular push-button key, guided in the housing, with aperture plate and with an after-connected interrogating circuit, responding to the switching condition of the phototransistor. A rectangular leaf spring, curved transversely to the longitudinal direction, supported with its corners upon ribs of the push-button key inner surface and curved away from the push-button key inner surface, and the counter-support of the leaf spring is formed by a pin in the geometrical mid-point.
