摘要:
The invention relates to a microsystem, comprising a magnetic microactuator (2, 2′), with a mobile element supported by a substrate (3) and controlled by magnetic effect between a first position and a second position for switching at least one electric circuit, whereby a permanent magnet or a solenoid subjects the mobile element to a first uniform magnetic field (B0) to hold the same in the first position, an energising coil (4, 6), external to the substrate (3), said energising coil (4, 6), on energising the above, submits the mobile element to a second magnetic field (BSi) to move the mobile element from the first position to the second position, the energising coil being of the solenoid type and surrounding the substrate supporting the mobile element.

An electrical switching device that can be employed in a sliding button, a rotating button, in a position switch, or an impact sensor. This device includes: a permanent magnet creating a magnetic field and a microswitch controlled between at least two states, by being aligned along two different orientations of field lines of the magnetic field of the permanent magnet. The microswitch and the permanent magnet are fixed relative to one another and a movable ferromagnetic part is moved between two positions so as to act on the orientation of the field lines generated by the permanent magnet so as to impose on the microswitch one or other of its two states.

Planar magnetic sensor, made in particular via CMOS techniques on a semiconductor substrate (1) of for example parallelepiped shape. It includes an amorphous ferromagnetic core (10) in the shape of a Greek cross which occupies the two diagonals of the square defined by the outer contour (90) of the excitation coil (9), the latter being made in the form of a planar winding of square shape. One thus measures, via flat detection coils (70, 80 and 71, 81) which are mounted in series and in a differential arrangement, the two orthogonal components (H1, H2) of the external magnetic field (Hext).

The present invention relates to a control device (1, 1′) of an electrical circuit comprising: a microswitch (2, 2′) comprising a moving element that can be driven by magnetic effect between a first stable state and a second stable state to control the electrical circuit, a fixed permanent magnet (10, 10′), a moving permanent magnet (11, 11′) that can be actuated between a first position, in which it forms, with the fixed permanent magnet (10, 10′), a substantially uniform permanent magnetic field (B0) holding the moving element in the first state or the second state, and a second position in which it is able to control the switchover of the moving element from one state to the other, an excitation coil (4) able to create a temporary magnetic field (Bb) able to cause the moving element to switch over from one state to the other when the moving permanent magnet (11, 11′) is in the first position.
摘要:
A device for detecting three states, namely ‘on’, ‘off’ and ‘triggered’ of an electric circuit breaker. The device includes a mobile magnetic device, movable between three positions corresponding to the three states of the circuit breaker, and at least one permanent magnet generating a magnetic field provided with magnetic field lines for driving two DIP switches via the magnetic effect. In each of the magnetic device's positions, the two DIP switches are controlled in either an open or closed position to form a specific combination representing one of the three states of the circuit breaker.

摘要:
A detection system that includes an emitter, a power supply source, a receiver, a detector, and a processor. The emitter includes a light-emitting diode that emits a luminous signal. The power supply source applies a constant voltage to the light-emitting diode. The receiver senses the luminous signal emitted by the light-emitting diode and generates a first input signal representative of the luminous signal detected. The detector measures the current passing through the light-emitting diode and generates a second input signal representative of the current measured. The processor is connected to the receiver and provides an output signal as a function of the first input signal and of the second input signal.
摘要:
An electrical switching device including a plurality of magnetic microswitches organized in a matrix on a substrate and each includes a mobile element driven between two stable positions held under the effect of a magnetic field, the device being characterized in that it includes a network of crossed conducting lines, wherein magnetic microswitches are positioned near to intersections formed by the conducting lines. The passage of an electrical current, through two conducting lines commands a change in position of the mobile element of the magnetic microswitch situated at the intersection of the two conducting lines.
