Miniaturized self-contained sensors for monitoring and storing data as to temperature and the like at remote areas and removable therefrom for digital reading, and novel method of operating the same
First Claim
1. The method of outputting digital data stored in a housing sensor device comprising conductive base and cap sections sealed together by an insulating gasket and that has monitored a parameter at a remote location and stored corresponding digital data, that comprises, removing the device of such location and inserting the same into a conductive well the cross sectional dimension of which is made slightly larger than the housing and of depth substantially equal to the length of the base section, to capacitively couple the housing base section to the inner wall of the well;
- establishing a radio-frequency ground connection about the housing cap section protruding above the well; and
communicating the data stored in the housing for external readout by means of a radio-frequency communication path through the capacitive coupling and the outer wall of the well.
