Abstract
An environmental logging system that includes a housing and an electronic logging circuit sealed within the housing. The logging circuit includes an energy source, transducer, charging circuit, trigger circuit, electronic control unit (ECU), and transmitter. The energy source is charged by the charging circuit using electricity from the transducer in response to external energy applied to the transducer. Commands may also be received by the circuit via the transducer. The ECU includes a processor, memory, and one or more sensors, and it operates under power from the energy source to store data from the sensor(s). The transmitter is coupled to the ECU and transmits the data via electromagnetic radiation outside the housing. The trigger circuit supplies operating power to the processor only when the voltage level of the energy source is above a minimum threshold. The housing may be a tubular shell filled with a polymeric material.
