Abstract: An apparatus and method for the early detection of a subject in a drowning or in a near-drowning situation in a body of water, such as a swimming pool, are disclosed. When the drowning or near-drowning situation is identified the apparatus issues an alarm signal that, in order to promote early rescue, attracts the relative, guest, friend or any other person. Following the identification of the alarm signal the potential rescuer is capable of initiating an immediate rescue operation and consequently requisite emergency medical procedures.

Abstract: A device adapted for mitigating the formation of a blood clot, the device comprising: a sensor adapted to identify muscle movement associated with blood circulation in a vein and to produce a signal indicating the movement; and a controller adapted to monitor the sensor signal and to activate an actuator upon said controller determining that less than a defined number of movements have been sensed over a defined period of time, wherein the actuator is adapted to produce a stimulating action of a given set of parameters urging the user to move his/her feet if, for example, the predefined number of dorsiflexions is not met.
