Abstract:
An RF signal is provided by a base such as a smart phone. A remote is engaged with a medication container. The remote includes an RFPM, RF signal receiver, LO signal generator, and IF signal emitter. An energizer on the remote provides power only as medication is dispensed. While energized, the RFPM modulates the RF signal with an LO signal to produce an IF signal. The existence of the IF signal (characteristic of the RFPM, RF signal, and LO signal) thus indicates medication has been dispensed. The IF signal is detected in the base, and registered (recorded, displayed, communicated, etc.) as an indication that medication has been dispensed. The remote may be configured as a label applied to or a sleeve engaged with an otherwise “non-smart” container. This provides authenticated data regarding medication adherence, transparent to the user and requiring no additional user actions to register the data.
