Abstract:
1. An electroencephalography (EEG) monitoring device, comprising: at least one electrode; a non-linear analog signal processor configured to receive a signal from the at least one electrode and determine whether the signal is within a significant category, wherein a significant EEG event is within the significant category, the non-linear analog signal processor comprising: a variable resolution analog-to-digital converter configured to convert signals received from the non-linear analog signal processor into high-resolution digital signals if the signals are within the significant category, and configured to convert signals received from the non-linear analog signal processor at a low resolution if the signals are not within the significant category; storage means configured to store high-resolution digital signals received from the variable resolution analog-to-digital converter; and a power source connected to, and providing power to, the non-linear analog signal processor, the variable resolution analog-to-digital converter, and the storage means.
