simple arrangements to detect a change in state location a device capable of detecting a change from idle state to moving state mems gyroscopes mems accelerometers tilt sensors vibration sensor or a combination of the above mems are micro electromechanical systems or microscopic machines with electrical and mechanical parts on a silicon chip gyroscopes can be any kind of angular rate sensors such as those manufactured by analog devices which generate output signals that are indicative of angular rates the output signals may be converted to data sequences using electronic components such as resistors and capacitors accelerometers can be any kind of acceleration sensors such as those manufactured by analog devices which generate output signals that are indicative of the acceleration the output signals are converted to data sequences transceiver 26 is any type of transceiver or a combination of transmitter and receiver in a preferred embodiment transceiver 26 conforms to bluetooth specifications 802 11 wilan or any other communication protocol bluetooth may also be spelled bluetooth with both terms considered equivalent herein transceiver 26 can discover other compatible transceivers in the vicinity transceiver 26 can establish a temporary two way connection or a piconet network with other devices equipped with compatible transceivers battery 24 provides power to some of the components of loss prevention system 10 it will be understood that battery 24 may be a fuel.
