Abstract: At least one electrical value for a plurality of frequencies is measured over a range of frequencies. An impedance is calculated based upon the at least one electrical value for each of the plurality of frequencies in the frequency range, the calculating producing a plurality of impedances. A maximum impedance from the plurality of impedances and a frequency associated with the maximum impedance are determined. The frequency is compared to a predetermined threshold, and based upon the comparing it is determined whether an earphone has been removed from the ear of a wearer.

Abstract: A seal assembly for use with a casing hanger that includes a pair of split rings held together by a threaded fastener. Torqueing the fastener axially compresses one of the rings so that it expands radially inward into sealing engagement with a wall of wellbore casing, and radially outward against an inner wall of a wellhead housing. Support grommets are provided where the fastener enters and exits the compressible ring. Protrusions on a side of the support grommets project into the compressible ring and create a sealing interface between each support grommet and compressible ring. O-rings line inner circumferences of the support grommets to seal between the support grommets and fasteners. A threaded end on a lower end of the fastener has a diameter less than an inner diameter of the O-rings to prevent damaging the O-rings during assembly.
