Analog Conversion for Radio Frequency Sensing

      Described is a hardware implementation that provides a means of
converting analog signals to Radio Frequency (RF) sensing so as to
provide a means of remotely identifying tagged information.

      In applications, such as temperature sensing used in
refrigerated trucks and railroad cars, prior art required manual
identification readings of the sensed values.  The concept described
herein utilizes an automatic equipment identification tag* interfaced
to an RS/232 communications device so as to allow 128 bits of data
written into the tag and read remotely as the tagged information
passes an RF antenna.

      Using this tag, with appropriate isolation and conditioning, a
variety of applications can be enabled, such as:  temperature status,
high/low temperature detection, fuel level, battery condition,
coolant temperature level, and gas pressure.
