Abstract
The presence of a child within an enclosed space in an appliance, such as a washing machine, dishwasher or refrigerator, is detected using one or more MEMS sensors positioned to detect movement within the enclosed space through various measured characteristics. In preference, combinations of different types of MEMS sensors are utilized to detect the movement. Movement may be attributed to the presence of a child inside the enclosed space, rather than resulting from other influences, with increased reliability if the determination is made based upon such combinations of different characteristics. Safety processes may be initiated upon detecting the presence of the child.
