    摘要: A processor comprises instructions to adjust a bias of an input signal in order to decrease a duty cycle of a pulse modulated optical signal. The bias can be increased, decreased, or maintained in response to one or more measured values of the signal. In many embodiments, a gain of the signal is adjusted with the bias in order to inhibit distortion. The bias can be adjusted slowly in order to inhibit audible noise, and the gain can be adjusted faster than the bias in order to inhibit clipping of the signal. In many embodiments, one or more of the bias or the gain is adjusted in response to a value of the signal traversing a threshold amount. The value may comprise a trough of the signal traversing the threshold.

    摘要: A hearing prosthesis, including an actuator assembly, and a chassis supporting the actuator assembly, wherein the actuator assembly is configured to vibrate when an electrical current is applied to the actuator assembly such that a first apparatus of the actuator assembly vibrates relative to a second apparatus of the actuator assembly, the chassis is connected to the second apparatus, and the actuator assembly retains data related to an operational performance of the actuator assembly.
