Abstract: A sensor for indirect estimation of breast milk intake by an infant, the sensor comprising: a housing configured to be externally attached to an incontinence product worn by a subject, said housing comprising: a light-emitting diode (LED) configured to illuminate the incontinence product; a photodetector configured to output an indication of the amount of light reflected from the incontinence product; and an integrated circuit configured to: (a) receive the indication from said photodetector, (b) compute, based on the indication, an amount of urine secreted by the subject into the incontinence product, and (c) estimate the amount of breast milk intake by the infant based on the amount of urine secreted by the subject into the incontinence product.

Abstract: A system for monitoring breathing of a subject, the system comprising: (a) a wearable subject unit comprising: an elastic resistive sensor positionable such that breathing motion of the subject applies mechanical pressure to said elastic resistive sensor, wherein said elastic resistive sensor is configured to change its resistance responsive to the mechanical pressure, and a transmitter configured to wirelessly transmit a signal based on the change in resistance of the elastic resistive sensor; and (b) a platform unit comprising a receiver and being positionable in wireless transmission range with said subject unit, said platform unit configured to receive said signal from said subject unit and to issue an advisory signal indicative of the breathing of the subject.
