Abstract: A display controller comprises at least one multifunctional encoder including a plurality of magnetic field sensors disposed within a housing cavity of the encoder in proximity to a permanent magnet attached to a knob shaft which is axially and rotatably movable in the housing cavity. The sensors are distributed angularly about the magnet to sense the magnetic field strength thereof based on the orientation of the permanent magnet with respect to the sensors. Each sensor is capable of generating an analog signal representative of the magnitude of the magnetic field strength sensed thereby.

Abstract: The invention relates to Electromagnetic Interference ("EMI") shielding of electrical components mounted on circuit boards. An EMI shielded assembly is provided, comprising a circuit board having at least one electrical contact distributed around the perimeter of an area within which EMI shielding is desired, an EMI shielding cover encircling the area over the contact and covering the area, and a ring-like EMI shielding gasket encircling the area and compressed between the contact and the cover, the gasket in an uncompressed state having low portions alternated with high portions spaced around the gasket. The high portions are spaced away from the at least one electrical contact above the low portions, and the high portions are displaceable toward the low portions upon compression of the gasket. A method for EMI shielding is also provided.
