Abstract
A method of communicating with an ingestible capsule includes detecting the location of the ingestible capsule, focusing a multi-sensor acoustic array on the ingestible capsule, and communicating an acoustic information exchange with the ingestible capsule via the multi-sensor acoustic array. The ingestible capsule includes a sensor that receives a stimulus inside the gastrointestinal tract of an animal, a bidirectional acoustic information communications module that transmits an acoustic information signal containing information from the sensor, and an acoustically transmissive encapsulation that substantially encloses the sensor and communications module, wherein the acoustically transmissive encapsulation is of ingestible size. The multi-sensor array includes a plurality of acoustic transducers that receive an acoustic signal from a movable device, and a plurality of delays, wherein each delay is coupled to a corresponding acoustic transducer. Each delay may be adjusted according to a phase of a signal received by the corresponding acoustic transducer.

16. A receiver that is communicatively coupled to an ingestible capsule, the receiver comprising:
-
a carrier generator configured to select a first and a second carrier frequency that are associated with a first and a second frequency channel, respectively, based on a hopping pattern; and a radiating element configured to acoustically receive, from the ingestible capsule, a first portion of data through a body of an animal as an original waveform in accordance with the first carrier frequency for a duration of the first frequency channel, wherein the carrier generator is further configured to switch from the first carrier frequency to the second carrier frequency before a reflection of the original waveform is received by the radiating element.
