20120197065 | Systems and Methods for Using a Simplified User Interface for Hearing Prosthesis Fitting - The present application discloses systems and methods for displaying and operating a user interface having one or more channel group controllers corresponding to one or more groups of hearing prosthesis channels. The hearing prosthesis may be configured to generate a plurality of signals via a plurality of channels based on a channel profile. The channel profile may define at least one intensity level for each channel. In operation, the user interface may be configured to instruct the hearing prosthesis to change the channel profile of the plurality of channels in response to receiving an input via one of the channel group controllers. The user interface may be used to fit a hearing prosthesis to a recipient. In one embodiment, an initial channel profile may be automatically determined, and the prosthesis channel profile may be adjusted by changing a representative intensity level corresponding to the channel profile. | 08-02-2012 |
20120226331 | Distributed Processing of Electrophysiological Signals - The present application discloses systems and methods for distributed processing of electrophysiological signals. The system may include a processor, a remote device, and an implant comprising an array of electrodes. The method may comprise the processor receiving an electrophysiological signal request from the remote device that specifies at least one electrode at the implant from which to receive an electrophysiological signal, transmitting to the implant instructions to apply a plurality of stimuli via the specified at least one electrode and, for individual stimuli in the plurality of stimuli, recording an electrophysiological signal component resulting from the stimulus. The method may also comprise the processor combining the recorded individual electrophysiological signal components to produce the electrophysiological signal and transmitting the electrophysiological signal to the remote device for further processing. In some embodiments of the method, the processor may compress the electrophysiological signal before transmitting it to the remote device. | 09-06-2012 |

20110015700 | PROVISION OF STIMULUS COMPONENTS HAVING VARIABLE PERCEPTABILITY TO STIMULATING DEVICE RECIPIENT - The automatic measurement of evoked compound action potential (ECAP) thresholds of the auditory nerve; that is, a neural response, concurrently with the performance of psychophysics measurements of a prosthetic hearing implant recipient. During the fitting process, a stimulus signal comprising two components is applied to each stimulation channel. One signal component is configured to elicit an ECAP neural response, referred to herein as a neural response signal component. The other component is configured to elicit a response to a psychophysics stimulation, referred to herein as a psychophysics signal component. Indications of the psychophysics measurement and the concurrently obtained neural response measurements are provided to the user. For the psychophysics measurement, this includes the selected characteristics of the psychophysics signal component since the results of the applied stimulation is a recipient behavioral or auditory response. | 01-20-2011 |

20090201970 | METHOD AND SYSTEM FOR MONITORING GAS MIXTURE QUALITY - A method and system for monitoring the quality of a given gas mixture being transmitted under pressure by throttling a sample of the gas mixture to a representative pressure and measuring the hydrocarbon dew point of the sample at the representative pressure. The measured hydrocarbon dew point is indicative of the cricondentherm of the gas mixture. The representative pressure is pre-selected to provide a pre-selected margin of error between measured hydrocarbon dew points of a set of representative gas mixtures at the representative pressure and respective cricondentherms of the set of representative gas mixtures. | 08-13-2009 |
