Embodiments of the present disclosure provide systems and methods for implementing a secure processing system having a first processor that is certified as a secure processor. The illumination means is arranged to one or both sides of said image capturing means and, in use, shines light towards the eyeball, the image processing software receiving data from the image capturing means, and by processing said data according to an algorithm establishes the distance between the surface of the eyeball and the camera. Each of the state machine replicas is provided with a request manager instance. The information collection apparatus receives data from the semiconductor apparatus via connection terminals of the semiconductor apparatus, and select the internal monitoring data from among the received data. The non-contact receiving space is adapted for receiving a portion of a mating connector housing and has a substantially rounded cross sectional shape substantially perpendicular to the direction from the mating side towards the rear side. This particular invention effectively increases the perceived stereo separation of the left and right front speakers, and creates the perception of two and even four surround speakers typically placed in the rear of the listening area.
