INGESTIBLE DEVICES FOR MEASURING PHYSIOLOGICAL PARAMETERS
First Claim
1. An ingestible apparatus for producing and processing physiological signals, the apparatus comprising:
- a physiological transducer circuit to sense physiological signals representative of a physiological parameter measured from within the body of a living entity;
a processor, responsive to the physiological transducer circuit, to process the physiological signals;
a transmitter to transmit the processed signals during transmission intervals which are alternated with idle intervals; and
a capacitor-based circuit, including at least one capacitor, to accumulate sufficient charge during one of the idle intervals to supply power to the transmitter during one of the transmission intervals.

Abstract
An ingestible apparatus produces and processes physiological signals representative of a physiological parameter. The apparatus measures the physiological parameter from within the body of a living entity. The apparatus includes a physiological transducer circuit to sense the physiological signals, a processor to process the physiological signals in response to the physiological transducer circuit, and a transmitter that transmits the processed signals during transmission intervals which are alternated with idle intervals. The apparatus further includes a capacitor-based circuit, including at least one capacitor, to accumulate sufficient charge during one of the idle intervals to supply power to the transmitter during one of the transmission intervals.

17. A method for producing and communicating a physiological parameter measured from within the body of a living entity using an ingestible apparatus that includes a physiological transducer circuit that senses physiological signals representative of the physiological parameter, a processor that produces and processes the physiological signals, a transmitter, and a capacitor-based circuit, the method comprising:
-
sensing the physiological signals by measuring the physiological parameter from within the body of the living entity; processing the physiological signals; powering the transmitter and transmitting the processed signals during transmission intervals during which the transmitter is powered by the capacitor-based circuit; and disabling the transmitter and charging the capacitor-based circuit during idle intervals that are alternated with the transmission intervals, the capacitor-based circuit accumulating sufficient charge during one of the idle intervals to supply power to the transmitter during one of the transmission intervals. - View Dependent Claims (18)
