PREVENTING WATER DAMAGE IN PORTABLE DEVICES

摘要

A shut-off circuit interrupts the flow of power to the system circuit of a portable device, when liquids are detected within the portable device. Liquid sensors are placed proximate to the ports of the portable device. The ports may admit the flow of liquids, so the liquid sensors may detect the passage of liquids into the portable device. If the liquid sensors detect liquids entering the portable device, a shut-off circuit interrupts the flow of power from the battery to the system circuit.
