BED MONITORING DEVICE

摘要

A bed monitoring device for monitoring bodily activity of a person and in particular vital signs such as respiration, cardiac activity and body's physical movement, including the presence, absence, step out or even falling out of a person using a sleeping environment such as a bed; mattress; top-mattress, bedding such as mattress covers, and pillow covers; a pad; a futon and the like. Based on the monitoring of bodily activity, it further allows determining sleep comfort and sleeping position of the user. It accordingly provides a valuable R&D tool to manufactures of sleeping articles like beds, mattresses, top-mattresses, futons and the like; but also in counseling consumers when buying sleeping articles under professional guidance. It comprises an optical fibre fixed to or mixed into a flat body positioned within said sleeping environment for detection of bodily activity by measuring a polarization variation of light propagating through the fibre.
