Low Power Device With Variable Scheduling
First Claim
1. A method of operating a medical device system, the method comprising:
- receiving at least one signal from a physiological sensor at a first time;
processing the at least one signal to detect pre-onset characteristics of a neurological event; and
scheduling subsequent receiving at least one signal and subsequent processing the at least one signal, wherein said scheduling is based at least in part on the processing of the at least one signal.

Abstract
Medical device systems and methods for operating medical device systems conserve energy by efficiently managing computational demands of the systems. Signals from a subject are processed and analyzed and an estimate of a propensity for a subject to have a neurological event is determined. Based on the results of the analysis and the estimate, further analysis may be performed and the estimate may be refined. Succeeding cycles of signal measurement and analysis are scheduled depending on the results of the analysis and the estimate. The schedule may be varied temporally or with regard to the types and intensities of analyses performed.

14. A neurological measurement system comprising:
-
at least one sensor input that receives at least one electrical signal indicative of a physiological measurement; logic arranged to process the at least one electrical signal and estimate a propensity for a future neurological event to occur; and a processor and memory programmed to activate the logic at a variable time interval wherein the variable time interval is adjusted in response to the estimate of a propensity for a future neurological event to occur. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. A system for estimating a propensity for a subject to have an epileptic seizure comprising:
-
at least one sensor input that receives at least one electrical signal indicative of a physiological measurement from a subject; first logic arranged to extract one or more characteristics from at least one electrical signal and to classify the extracted characteristics to estimate a first propensity of the subject to have an epileptic seizure; second logic configured to schedule subsequent signal receiving and subsequent extraction of one or more characteristics of subsequently received signals based at least in part on the estimate of a propensity for the subject to have an epileptic seizure. - View Dependent Claims (24, 25)
