DACS actuator
First Claim
1. A compensation system for an implantable direct acoustic cochlear stimulation (DACS) actuator having a sealed housing containing a driving arrangement for the actuator, the compensation system comprising:
- an external pressure sensor configured to measure an external pressure outside of the sealed housing; and
a compensation module configured to determine a compensation factor for the implantable actuator based on a pressure differential between the measured external pressure and an internal pressure within the sealed housing, and to combine the compensation factor with a stimulation signal to adjust the driving arrangement for the actuator.

Abstract
A compensation system for an implantable actuator is disclosed where the implantable actuator includes a sealed housing containing a driving arrangement for the actuator. The compensation system includes an external pressure sensor for measuring an external pressure outside of the sealed housing and a compensation module for determining a compensation factor for the implantable actuator based on the external pressure. In one embodiment, the compensation is directed to a direct acoustic cochlear stimulation (DACS) implantable actuator.
