20130006042 | Method and System for Configuration of a Medical Device that Stimulates a Human Physiological System - A method and system for automatically configuring a medical device that is at least partially implanted in a human recipient and that includes a transducer arranged to stimulate a physiological system of the recipient, such as a middle-ear implant for instance. The energy level of a signal provided to drive the transducer is progressively increased until there is a threshold electrical change indicative of a threshold change in impedance of the transducer. In the context of a middle-ear implant, for instance, the threshold electrical change indicative of the threshold change in impedance of the transducer may be indicative of the acoustic reflex. The energy level of the signal at that point is then used as a basis to set an operational parameter of the medical device, such as a comfort-level of the middle-ear implant for instance. | 01-03-2013 |
20140039576 | Automatic Sound Optimizer - Disclosed herein are systems and methods that help to optimize the sound quality produced when a sound processing mode is enabled in an audio device, such as a hearing prosthesis. When the sound processing mode is enabled, a sound processor in the audio device will create a candidate transformed signal based on a default set of parameters associated with the sound processing mode (i.e. a candidate signal processing function). Further, the sound processor will create a reference transformed signal based on the same enabled sound processing mode, but with a varied set of parameters (i.e. a modified signal processing function). The sound processor will then compare the candidate transformed signal to the reference transformed signal to determine which signal has a higher quality. The device then creates an output based on the higher quality signal. | 02-06-2014 |
20140177890 | Frequency Based Feedback Control - Disclosed herein is a feedback reduction system for used in a hearing prosthesis. The hearing prosthesis will receive an input signal, process the input signal, and create a transformed output. However, the hearing prosthesis may suffer from feedback. Thus, a system to minimize the feedback in a hearing prosthesis may be desirable. One system to minimize the feedback includes down-sample circuitry configured to down-sample a first signal, creating a down-sampled signal. They system also includes a filter circuit. The filter circuit filters both the first signal and the down-sampled signal. The filter will output a filtered signal and a filtered down-sampled signal, respectively. Additionally, the system features up-sample circuitry that up-samples the filtered down-sampled signal. The output of the up-sample circuitry is an up-sampled signal. Further, the system features combining circuitry that creates a feedback-reduced signal based on the up-sampled signal, the filtered signal, and an input signal. | 06-26-2014 |

Additionally, the processor of the hearing prosthesis system may also be arranged to communicate a second stimulation signal to a vibration stimulator of the second hearing prosthesis. The processor receives an indication of a measured input signal from the first hearing prosthesis. Further, the processor calculates a second feedback associated with the second stimulation. | 09-18-2014 |

The predicted change may be based on one or more characteristics of an external feedback loop. Responsive to identifying the feedback artifact, the sound processor is further configured to apply a modification to a parameter used to process the input spectral component. The modification reduces a likelihood of including audible feedback in a processed input spectral component. | 09-18-2014 |
