Abstract: An apparatus for location of objects is provided. The apparatus includes an integrated circuit including a processor, a memory, a transceiver for sending and receiving data over a cellular network, and GPS receiver components for receiving GPS signals. The apparatus further includes an outer housing which may be operatively affixed to an object. Responsive to a notification over the cellular network from a subscriber, the apparatus determines location information and transmits the location information to the subscriber. In one embodiment, the apparatus is powered by a MEMS power source configured to harvest mechanical energy for conversion to electrical energy.
