Abstract:
A power supply circuit comprises an input for receiving a power supply from a battery and a DC/DC converter for supplying a converted voltage to a load. A regulator is used for controlling the DC/DC converter such that the current drawn from the converter is smoothed. A charge storage device at the output of the DC/DC converter enables delivery of a non-constant current to the load.
Abstract:
There is disclosed herein a sensor for detecting at least one of urination and excretion into an incontinence garment, the sensor comprising an activation unit and a sensing unit and being connectable to a power supply; the activation unit comprising: two spaced-apart electrodes, and a switch arranged in series between the sensing unit and the power supply; wherein the activation unit is configured to activate the sensing unit in the presence of moisture by closing the switch; and wherein at least one of the sensing unit and the activation unit comprises a latching circuit arranged such that the activation of the sensing unit is irreversible. An incontinence garments such as the diaper is incorporating such a sensor is also disclosed as it is a method for operating such a sensor or incontinence garment.
