Abstract

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.

Dependent claims

A device for use in a system for processing electrophysiological signals, the device comprising:

an input configured to receive, from a remote device, an electrophysiological signal request specifying at least one electrode from which to receive an electrophysiological signal;
a first output configured to transmit to an implanted component of a hearing prosthesis instructions for applying a plurality of stimuli via the specified at least one electrode;
a recording module including one or more amplifiers, wherein the recording module is configured to record an electrophysiological signal component resulting from each stimulus in the plurality of stimuli applied by the stimulation device;
distortion detection circuitry configured to determine that one or more of the recorded electrophysiological signal components have been distorted as a result of saturation of one of the one or more amplifiers in the recording module,
logic configured to eliminate the one or more recorded electrophysiological signal components determined to have been distorted as a result of saturation of one of the one or more amplifiers in the recording module such that only a plurality of non-distorted recorded electrophysiological signal components remain;
a combiner configured to combine only the plurality of the non-distorted recorded electrophysiological signal components to produce the electrophysiological signal;
and
a second output configured to transmit, to the remote device, the electrophysiological signal that includes only the non-distorted recorded electrophysiological signal components.
