Methods and systems for acoustic data transmission
First Claim
1. A method for communicating with an ingestible capsule, comprising:
- selecting a first and a second carrier frequency that are associated with a first and a second frequency channel, respectively, based on a hopping pattern;
acoustically transmitting, by 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; and
switching, by the ingestible capsule, from the first carrier frequency to the second carrier frequency before a reflection of the original waveform is received by a receiver that is communicatively coupled to the ingestible capsule.

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.
