    Abstract: A current sensor arrangement comprises plural sensor elements arranged around a center point, each of the sensor elements having a plane of zero sensitivity to uniform magnetic fields. A first one (202) of the sensor elements has a first angular separation (X1) relative to the center point from a second, adjacent sensor element (204) and a second angular separation (X2) relative to the center point from a third, adjacent sensor element (206). The first angular separation is less than the second angular separation. An intercept (I13) of the planes of the first and third sensor elements is located outside a triangle formed by the center point and the first and third sensor elements and an intercept (I12) of the planes of the first and second sensor elements is located inside a triangle formed by the center point and the first and second sensor elements.

    Abstract: An electroacoustic transducer comprises a pair of active piezo electric membranes and a sleeve closed at its ends by the membranes to a form an enclosed rear volume of air. A case accomodates the assembly of sleeve and membranes and provides an enclosed front volume of air between its inner wall and the assembly. An opening in the case to the outside forms a sound pressure output. Each membrane comprises a sandwich of two active piezo layers on a substrate material. Very small thicknesses of the substrate and active piezo layers provides for a correct impedance match to the acoustic load in the ear when used in hearing aids.

    Abstract: A magnetic latching actuator operable to control the movement of at least a first contact and second contact between a closed position in which the contacts physically engage each other and an open position in which the contacts are spaced from each other. The magnetic latching actuator includes first and second stationary permanent magnets oriented such that the first magnetic field created by the first magnet and the second magnetic field created by the second magnet are in opposite directions. An actuation coil surrounds both the first and second magnets. Current is supplied to the actuation coil in a first direction to create a first magnetic field or a second direction to create a second actuation magnetic field opposite the first actuation magnetic field. A yoke is movable relative to the first and second magnets to cause the first and second contacts to move between the open and closed positions.
