ASSEMBLY AND A METHOD OF DETERMINING A CHANGE IN CAPACITANCE

摘要

An assembly and a method for determining a change in capacitance in a cable, such as a change caused by a deformation of the cable. The deformation may be caused by a deforming element attached to the cable and slideable along the cable. The deforming element may be adapted to be compressed by a user and convert the compression force into a compression of the cable so as to cause the capacitance change. The assembly may form part of a headset and the deformation may be used to control a media player or mobile telephone used with the headset.

主权项

1. An assembly comprising:
a cable comprising at least two elongate, co-extending electrical conductors, a sensor configured to determine a change in capacitance between a first and a second of the conductors and output a corresponding electrical signal, and a deforming element attached to the cable so as to be translatable along the cable,the deforming element comprising:
engaging elements configured to engage with the cable, a deforming part, an energy storage configured to provide energy to the deforming part, the deforming part being configured to convert at least part of the provided energy into a temporary deformation of the cable, and an activator configured to receive a force and activate the deforming part, when the received force exceeds a threshold force.
