1. A method of operating a medical device system, the method comprising:
- receiving at least one signal from a physiological sensor;
processing the at least one signal by performing a first analysis to estimate a first propensity for a subject to have a neurological event; and
performing a second analysis to estimate a second propensity for the subject to have a neurological event when the first estimate meets one or more specified criteria.

Abstract
Medical device systems and methods for operating medical device systems conserve energy by efficiently managing computational demands of the systems. A first analysis, having relatively lower computational processing demand than at least a second analysis, processes signals from a subject to determine a first estimate of a propensity for the subject to have a neurological event. If the first estimate meets a set of specified criteria, a second analysis is performed to determine a second estimate of the propensity for the subject to have a neurological event.

18. A system for estimating a propensity for a subject to have a neurological event comprising:
-
one or more sensors for measuring at least one signal from the subject; first logic arranged to analyze the at least one signal from the subject and estimate a first propensity for the subject to have a neurological event; a processor configured to perform the first logic; second logic configured to be performed when the first estimate meets one or more specified criteria and arranged to estimate a second propensity for the subject to have a neurological event. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A device comprising:
-
means for measuring at least one signal from a subject; means for analyzing the at least one signal from a subject to estimate a first propensity for the subject to have a neurological event; means for determining whether the estimate of the first propensity meets one or more specified criteria; means for estimating a second propensity for the subject to have a neurological event when the estimate of the first propensity meets the one or more specified criteria.

29. A system for estimating a propensity for a subject to have an epileptic seizure comprising:
-
at least one sensor for measuring at least one neurological signal from the subject; first logic arranged to extract at least one feature from the at least one neurological signal and to classify the extracted at least one feature to estimate a first propensity of the subject to have an epileptic seizure; a processor configured to perform the first logic; second logic arranged to estimate a second propensity of the subject to have an epileptic seizure when the estimate of the first propensity meets at least one specified criteria; and a processor configured to perform the second logic. - View Dependent Claims (30, 31, 32, 33, 34)
