Abstract: Various embodiments of the invention provide systems and methods for accurately determining temperatures in harsh environments such as, for example, in a steam autoclave chamber during a sterilization cycle. In certain embodiments, temperature data accuracy is increased by utilizing an IC-based temperature logging device that monitors and compensates for inherent thermal delays that would otherwise cause a discrepancy between temperature as measured by a temperature sensor and the actual ambient gas temperature. By properly correcting for the thermal delay, the data accuracy of the measured gas temperature is thus greatly enhanced.

Abstract: The present invention comprises a circuit for transferring N inputs, wherein N is greater than or equal to 2, across a capacitive coupling media comprising a line circuit, a coupling capacitor, and a neutral potential circuit. The line circuit comprises: (1) a data converter for each input, for sampling and converting the N inputs; (2) a multiplexer for combining the outputs of the N data converters and a synchronization signal to generate an unencoded composite bit stream; (3) a data encoder for encoding the composite bit stream. The capacitor couples the encoded composite bit stream to a data decoder. The neutral potential circuit comprises: (1) the data decoder for decoding the coupled composite bit stream, and generating a recovered data stream and a recovered clock; (2) a synchronization recovery, control logic, and de-multiplex function for providing a set of digital outputs that correspond to the inputs to the data converters.
