Patent ID: 8746036

Claim:
A method for storing sensor information, comprising the steps of: selectively heating one or more of a plurality of sensors in an array by a corresponding a heating element; sensing one or more parameters by each of the one or more of the plurality of sensors in the array that have been heated, each sensor providing an output current in accordance with a level of the sensed parameter; sensing one or more parameters by each of a the one or more of the plurality of sensors in the array that have not been heated, each sensor providing an output current in accordance with a level of the sensed parameter; receiving the output current and generating an output oscillation frequency in accordance with the level of the received output current by a plurality of Voltage Controlled Oscillators (VCOs) in an array, each such VCO corresponding to one of the sensors; and counting a number of oscillations generated at each of the VCOs over a predetermined time by a plurality of counters in an array, each such counter corresponding to one of the VCOs.
