The invention relates to a Hall effect sensor for recording the direction of a magnetic field, comprising a plurality of Hall effect sensor elements () arranged in pairs, wherein each pair comprises a first Hall effect sensor element () and a second Hall effect sensor element () which are arranged parallel to one another. The Hall effect sensor has a first switch () for disconnecting the first Hall effect sensor element () from a power supply ().

Hall effect sensor

A method and an arrangement () for detecting the actuation of an operator-controlled element () make possible a reliable detection of an operator-controlled function to be activated by the operator-controlled element () independently of environmental and wear conditions. The operator-controlled element () can be actuated with different adjustable degrees of actuation. Various operator-controlled functions of the operator-controlled element () are realized in dependence upon the degree of actuation. The operator-controlled element () is actuated against a spring force and at least two degrees of actuation are characterized by different spring constants. The at least one of the operator-controlled functions of the operator-controlled element () is detected in dependence upon the spring constant assigned to the instantaneous degree of actuation.

A device for wireless transmission of a deployment signal. The device includes two processors on both the primary side and the secondary side, which exchange data with one another. A high degree of redundancy is thereby achieved. The wireless transmission is preferably carried out as inductive transmission.

Deployment of vehicle safety restraint via wireless trigger signal

A system for transmitting data and/or energy between a chassis and a seat movably arranged on the chassis, the seat being able to glide in guide rails, attached to the chassis, with the aid of slides; one iron-core half of a transformer&#x2014;the iron-core half bearing at least one primary winding&#x2014;is disposed on the slide gliding in the guide rail, the primary winding being a cable lying in the guide rail; and the other iron-core half of the transformer having a secondary winding is arranged on the seat, the two iron-core halves of the transformer being positioned relative to each other for the data and/or energy transmission when the seat is mounted.

A system for transmitting data and/or energy between a chassis and a seat that is movably arranged on the chassis, the seat being able to glide with the aid of slides in guide rails attached to the chassis; one iron-core half of a transformer, the iron-core half bearing at least one primary winding is positioned on the slide gliding in the guide rail, the primary winding being a cable in the guide rail; and the other iron-core half of the transformer, having a secondary winding, is positioned on the seat, the two limbs of the other iron-core half being arranged in the longitudinal direction with respect to the guide rail, and both iron-core halves of the transformer being positioned relative to each other for the data and/or energy transmission.

The invention relates to an inductive transmitter for transmitting measurement data and electrical energy between two components () that move in relation to each other, having at least one primary () and at least one secondary transmitter component (). There is one transmitter () for transmitting measurement data and one transmitter () for transmitting electrical energy, with the primary () and secondary () transmitter components being disposed in separate chambers () that are magnetically shielded from each other to a large extent. The chambers () are formed on the components by concentric, radial metal walls of the chamber elements (), with the concentric walls extending into each other in such a way that they form chambers () situated radially one behind the other.

Inductive transformer

A system for the wireless transmission of information and energy between a removable vehicle seat and the vehicle body, in which the vehicle seat is detected by measuring the inductance. In this connection, the period of an oscillating circuit is determined, in which the winding of the primary side, and thus the inductance, is connected. In this context, the frequency of the resonance voltage is determined as a function of time. In this context, the zero crossings of the resonance voltage is measured. Alternatively, the secondary side impedance is additionally measured on the primary side by a forced oscillation, namely by a voltage decay in a resonance circuit in which the winding is connected as inductance. A monitoring of the performance reliability of a firing pellet is thereby implemented.

A device is provided for transmitting data or energy to a system of restraint in a vehicle, which is used for connecting movable vehicle parts by a transformer. According to an exemplary embodiment of the present invention, a reed contact is provided on the secondary side of the transformer which short-circuits the winding or the coil when the movable part is removed. This short-circuit prevents an induction voltage from leading to an undesired triggering of the restraint arrangement.

Device for transferring data and/or energy to restraining means in a vehicle

A device for wireless transmission of a trigger signal, in particular for a restraint system, which has a redundancy path to ensure reliable triggering of a restraint system, is proposed. On a primary side of a transmitter a redundancy unit is arranged; this generates a redundancy signal from a trigger command, the redundancy signal being detected by an enable unit on the secondary side in order to enable a trigger circuit for the restraint system, the trigger circuit then being triggered by an evaluation unit on the secondary side via a trigger signal. The trigger circuit triggers a restraint system.

Data bus for constraint devices, which connects a control unit to the constraint devices, which are connected to the data bus via transformers. The data is then transmitted over the data bus using frequency shift keying signals. The constraint devices are each provided in removable seats. Upon activation of the constraint devices, a deployment signal is sent to the constraint devices over a power supply line.

Data bus for constraint means in a vehicle

A device for the wireless transmission of a tripping signal for a restraint system, a firing command from a firing bus being converted by a filter into a firing signal, which can be transmitted via an inductive or capacitative transformer. On the secondary side of the transformer, a regeneration device is arranged, which reconstitutes from the firing signal a firing command, which then is used to trigger a restraint system. The restraint system can be connected to a bus simulation, so that the driving electronics for the restraint system are the same as those which are connected directly to the firing bus.

An inductive transformer for transmitting measurement data and/or electrical energy between two components ( ) moving relative to one another includes one primary and one secondary transformer part ( ), in which a gap is formed between the moving components ( ). A slide ring ( ), which is made of a plastic with embedded ferromagnetic metal parts is disposed in the gap. The metal parts are distributed nonhomogeneously in the plastic, such that their proportion, on the end with which it is solidly disposed on one of the components ( ), is high and becomes relatively slight toward the end with which it rubs against the respective other component ( ).
