A multiple axis sensor assembly includes an enclosure and encapsulated microelectromechanical system sensors. To couple a sound tube to an earpiece, a connection element can be provided on the sound tube, which connection element can be connected to a connection element for the earpiece. According to yet another aspect, conditional processing is avoided by providing a common arithmetic operation when decoding code-words in various escape modes, but using neutral operand values in case the operation is not required. The first portion of the silicon containing film is thinned in the thickness direction. 65 V and the no-load cell voltage response is monitored at predetermined intervals. The disclosed embodiments are particularly useful in minimally invasive surgical techniques such as laterally performed anterolisthesis and retrolisthesis.
