A method for making a subsurface electrical contact on a micro-electrical-mechanical-systems device. The elastomeric material is then penetrated with a needle and a quantity of softer material is injected through the needle into the sealed compartment. The pulse-count detection sensor unit 32 and the rotational-direction detection sensor unit 33 are arranged such that a phase difference occurs between the signals of the sensor unit 32 and the signals of the sensor unit 33, so that it is possible to detect the rotational direction of the rotary bezel. The backer rod hereof is a continuously extruded closed-cell foam body that is degassed by a secondary extrusion. At least one of the current source cells further includes a calibration circuit configured to detect a voltage variation at the gate terminal and provide a compensation voltage for the compensation capacitor. More particularly, the antenna assembly may include a flexible substrate, an electrically conductive antenna element on the flexible substrate and connected to the wireless communications circuitry and the ground plane, and a floating, electrically conductive director element on the flexible substrate for directing a beam pattern of the antenna element.
