System of monitoring a person in a living space
First Claim
1. A system for monitoring a lifestyle of a person in a living space, comprising:
- sensors located in the living space for detecting at least one of a presence of the person and an activity of the person, anda processor coupled to the sensors for;
deriving events caused by the person and times when the events occur,detecting event-free periods, each of a first length, in which no events of a predetermined group occur, andderiving an estimate of in-bed time on the basis of a beginning of one said event-free period of at least the first length, detected in a first observation period beginning before a usual in-bed time, whereby the estimate of the in-bed time is determined by said beginning and is indicative of an actual time that the person has gone to bed, and whereby the usual in-bed time is representative of a time that the person usually goes to bed.

Abstract
A system for monitoring a lifestyle of a person in a living space includes sensors for detecting a presence of the person and/or an activity of the person, and a processor controlled system, coupled to the sensors for deriving events caused by the person and times when the events occur, for detecting event free periods of first lengths in which no events of a predetermined group occur, and for deriving, an estimate of in-bed time on the basis of the event free period of at least the first length detected in a first observation period beginning before a usual in-bed time, and for determining an estimate of the out-bed time on the basis of the events, and event free periods of at least a second length, detected in a second observation period ending after an usual out-bed time.
