MONITORING DEVICE FOR SUBJECT BEHAVIOR MONITORING

摘要

A subject behavior monitoring device is for monitoring the behavior of a subject based on their usage of a plurality of fluid outlets of a fluid supply system in a building. An acoustic measurement unit is adapted to generate an acoustic monitoring signal which varies in dependence on a fluid flow from the plurality of fluid outlets. A signal processor processes the acoustic monitoring signal and is adapted to detect usage of each of the plurality of fluid outlets and determine which usages were carried out by the subject being monitored. In this way, the behavior of a subject, in terms of their usage of fluid outlets, such as water taps and gas appliances, can be detected and also discriminated from other occupiers of the building in which the subject is resident.
