Abstract:
1. An ingestible apparatus for producing and processing physiological signals, the ingestible apparatus comprising: a physiological transducer circuit configured to sense physiological signals representative of a physiological parameter measured from within a body of a living entity; a processor, responsive to the physiological transducer circuit, that is configured to process the physiological signals to produce processed signals; a transmitter configured to transmit the processed signals during transmission intervals which are alternated with idle intervals; a capacitor-based circuit, including at least one capacitor, configured to accumulate sufficient charge during one of the idle intervals to supply power to the transmitter during one of the transmission intervals; a power supply; and startup circuitry responsive to an external RF signal configured to permit flow of charge from the power supply to the capacitor-based circuit.
