Methods and systems for acoustic data transmission
First Claim
1. A method of acoustic communication of information, comprising;
- sensing a stimulus via one or more sensors;
generating a sensor output signal based on the sensed stimulus;
selecting a frequency channel from among a plurality of frequency channels based on upon a time interval;
encoding an acoustic communications signal onto the selected frequency channel based on information from the sensor output signal by varying a length of time delay in a transmission between adjacent frequency channels; and
acoustically transmitting the encoded acoustic communications signal.

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.
