Patent ID: 7337078

Claim:
An asset interface device comprising: a clock circuit intermittently activating a circuit of said device for a predetermined period of operation; a sensor circuit communicating with said clock circuit, wherein said sensor circuit is responsive to operational data related to an asset communicating with said asset interface device; a transceiver circuit communicating with said sensor circuit, wherein said transceiver circuit transmits and receives said operational data during said predetermined period of operation; and a control circuit communicating with and interposed between said sensor circuit and said transceiver circuit translating said operational data during said predetermined period of operation, wherein said clock circuit, sensor circuit, transceiver circuit, and control circuit each operate as ultra low current consuming circuits, which provide for an intrinsically safe classification of said asset interface device without having to rely on an enclosure enclosing said clock circuit, sensor circuit, transceiver circuit, and control circuit for said intrinsically safe classification.
