The processing unit comprises:
Two omni-directional microphones for receiving sound.•
An internal telecoil for receiving magnetic fields radiated by •
phones, neckloops and roomloops (optimised for phone use).
Custom analogue and digital integrated circuits with digital signal •
processing (DSP) and bi-directional wireless communication
capabilities.
A dual-colour light emitting diode (indicator light) for visual •
indication of processor function or processor problem.
Two push-buttons to allow user control of key features.•
Custom 4-pin accessory connector for connection of audio •
accessories (e.g. Personal Audio Cable).
Custom 4-pin coil connector for connection of the coil cable. •
A range of earhooks.•
The batteries provide power to the processor. The following options are
available for powering the processor:
Two disposable batteries.•
Rechargeable battery module.•
The coil acts as a transformer coupling that transfers energy and data
information to the implant. It is connected to the processing unit by
the coil cable. The coil cable is a separate cable, which can be detached
from both the coil and the processing unit. It is connected to both
the coil and the processing unit by custom 4-pin connectors. The
connection forms a seal to prevent moisture ingress.
