  • Patent number: 10991644
    Abstract: A method of providing a sensor IC package can include applying a film to a leadframe having first and second surfaces, mounting at least one component to the film, and applying a pre-mold material to cover at least a portion of the leadframe and the passive component while leaving a first side of the leadframe exposed. The film can be removed and a die attached to the first side of the leadframe. At least one electrical connection can be formed between the die and the leadframe. The assembly of the die, the leadframe, and the pre-mold material can be encapsulated with a final mold material to provide a low profile IC package.

  • Patent number: 10955306
    Abstract: A pressure sensor comprises a deformable substrate, at least one coil supported by the substrate and responsive to a changing coil drive signal to produce a changing magnetic field, a fluid chamber having a first wall formed by the substrate and a second wall formed by a conductive material and positioned proximate to the at least one coil so that the changing magnetic field produces eddy currents within the conductive material that generate a reflected magnetic field, and at least one magnetic field sensing element configured to detect the reflected magnetic field and produce a signal responsive to a distance between the magnetic field sensing element and the second wall. The substrate is deformable by fluid pressure within the fluid chamber and the deformation of the substrate changes the distance between the magnetic field sensing element and the second wall.

  • Publication number: 20200379501
    Abstract: A joystick assembly for use with a device including a joystick surface and a first magnet having north and south magnetic poles includes a second magnet having north and south magnetic poles and a movable elongated shaft having first and second opposing ends arranged along a major axis of the shaft. The first end of the shaft is coupled to the second magnet such that movement of the shaft results in movement of the second magnet relative to the first magnet such that a line between centers of the north and south magnetic poles of the second magnet is movable relative to a line between the north and south magnetic poles of the first magnet. An attraction of the second magnet to the first magnet results in a restoring force upon the shaft, and the shaft and the second magnet are removable from the joystick surface.

  • Publication number: 20200284676
    Abstract: A pressure sensor includes a conductive substrate having a cavity which forms a thin portion that can be deformed by a pressure differential. A magnetic field sensor has at least one coil responsive to a changing coil drive signal and positioned proximate to the thin portion of the substrate that induces eddy currents in the thin portion that generate a reflected magnetic field. Magnetic field sensing elements detect the reflected magnetic field and generate a magnetic field signal. The magnetic field sensor is positioned so that deformation of the thin portion of the substrate causes a distance between the thin portion of the substrate and the magnetic field sensor to change.
