METHOD AND SYSTEM FOR ACTIVITY/REST IDENTIFICATION
First Claim
1. A method for identification of activity and rest periods based on an actigraphy signal, said method comprising:
- (a) applying one or more filters to said actigraphy signal to generate a filtered actigraphy signal using a processing hardware element; and
(b) comparing said filtered actigraphy signal against an adaptive threshold to generate an output signal corresponding to said activity and rest periods.

Abstract
Disclosed embodiments include a method for automatic identification of activity and rest periods based on an actigraphy signal. According to an embodiment, the method comprises (a) applying one or more filters to the actigraphy signal to generate a filtered actigraphy signal, and (b) comparing the filtered actigraphy signal against an adaptive threshold to generate an output signal corresponding to the activity and rest periods. The method can be implemented as part of a medical apparatus or medical system for automatic activity/rest identification from actigraphy signals.
