A filtering capacitor feedthrough assembly for an implantable active medical device is disclosed. A layer of analytical material is formed on a transparent layer overlying a solid state image sensor. Both the front and the rear channels are configured to allow rotational movement along two axes by having the socket moving on top of the ball and having the front hook moving within the front channel and the rear hook moving within the rear channel. This can enhance portability and a storage characteristic of the position information input system.
