Method and Apparatus for Collecting and Providing Sensor Data

An electronic register comprising:

• communication interface circuitry configured for communicating with one or more external devices;
• a sensor interface circuit configured to interface with an external sensor;
• processing circuitry including or operatively associated with the communication interface circuitry, the sensor interface circuit, and storage, said processing circuitry configured to:
• receive conversion data from a first external device, for the sensor interface circuit, said conversion data comprising information for converting raw sensor data obtained from the external sensor into corresponding physical-domain measurements;
• store the conversion data in the storage, in logical association with the sensor interface circuit;
• obtain the raw sensor data from the external sensor, via the sensor interface circuit, and log the raw sensor data in the storage, in logical association with the stored conversion data, and without converting the logged raw sensor data into the corresponding physical-domain measurements;
• and
• responsive to a trigger, output the stored conversion data and the logged raw sensor data logically associated with the stored conversion data, to the first external device, or to a second external device.

A method implemented by an electronic register comprising:

• receiving conversion data for each of two or more sensor interface circuits of the electronic register, wherein the conversion data received for each sensor interface circuit comprises information for converting raw sensor data obtained from the sensor interface circuit into corresponding physical-domain measurements;
• storing the conversion data received for each sensor interface circuit in logical association with the sensor interface circuit;
• logging the raw sensor data obtained from each sensor interface circuit in logical association with the conversion data received and stored for the sensor interface circuit, and without converting the raw sensor data into the corresponding physical-domain measurements;
• and
• outputting the logged raw sensor data for any one of the sensor interface circuits to an external device, along with the conversion data received and stored for the sensor interface circuit, thereby enabling the external device to convert the logged raw sensor data into the corresponding physical-domain measurements.
