Abstract
An active medical device, including an input receiver configured to receive a frequency-varying input signal, and a functional component that reacts to the input signal and consumes power at a rate dependant on the frequency of portions of the input signal to which the functional component reacts, wherein the active medical device is configured to adjust one or more portions of the input signal corresponding to portions of the input signal where the functional component consumes power at a rate that is greater than that of other portions of the input signal.
Claims23
An active medical device, comprising:
- an input receiver configured to receive a frequency-varying input signal;
- and
- a functional component that reacts to the input signal and consumes power at a rate dependent on a frequency of the input signal to which the functional component reacts,
- wherein the device is configured to make an adjustment of one or more portions of the input signal where the functional component consumes power at a rate that is greater than that of other portions of the input signal.
An active medical device comprising:
- a functional component that has a parameter-dependent power consumption profile;
- and
- a power-smoothing circuit configured to determine an intensity level of a frequency-varying input signal, and to adjust, based on the intensity level, a parameter referenced by the functional component upon which the parameter-dependent power consumption profile depends so as to selectively reduce power consumption of the functional component, wherein
- the functional component is operably responsive to the adjusted parameter.
An active medical device, comprising:
- an external component including an input receiver configured to receive a frequency-varying input signal;
- and
- an implantable component configured to output stimulation to a recipient of the medical device to evoke a hearing percept based on the frequency-varying input signal, wherein
- the external component is configured to communicate with the implantable component via a transcutaneous wireless link,
- the device is configured to recognize a loudness level of an environment of the device, and adjust a duty cycle of the wireless link based on the recognized loudness level to manage power consumption by the device.
