    • 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.
    • 与可摄入胶囊通信的方法包括检测可摄入胶囊的位置,将多传感器声阵列聚焦在可摄取胶囊上,以及经由多传感器声阵与可摄取胶囊通信声信息交换。 可摄入胶囊包括接收动物胃肠道内的刺激物的传感器,发送包含来自传感器的信息的声学信息信号的双向声学信息通信模块以及基本上包围传感器和通信模块的声透射封装, 其中所述声透射封装具有可摄取的尺寸。 多传感器阵列包括从可移动装置接收声信号的多个声换能器和多个延迟,其中每个延迟耦合到对应的声换能器。 每个延迟可以根据由相应的声换能器接收的信号的相位进行调整。
