Abstract: When a multitude of devices (200) operate in a transmissive medium (206) and absorb a mechanical wave signal, absorption of the signal by devices (200) closer to the transmission source (208) may limit available signal strength experienced by devices located further from the source. Device design and/or operation can be adjusted to mitigate such attenuation. For example, the properties and/or actions of closer devices can be adjusted to reduce their absorption of the signal, including limiting the action of the absorptive structures employed and/or changing the frequency of absorption.

Abstract: Devices, including robotic devices, operating in viscous fluid flow can use passive sensor data collected to represent fluid parameters at an instant in time to derive information about the flow, the motion and position of the device, and parameters of the physical system constraining the flow. Using quasi-static analysis techniques, and appropriate feature selection for machine learning, very accurate determinations can be made, generally in real time, with very modest computational requirements. These determinations can then be used to map systems, navigate devices through a system, or otherwise control the actions of, e.g., robotic devices for clean-up, leak detection, or other functions.

Abstract: Methods are disclosed for operating devices in diffusion-limited regimes, where diffusion rates are sufficiently low that device operation can be optimized by taking the rate of diffusion into account when directing devices what actions to take.

Abstract: Devices and methods are described for transmitting acoustic waves through a fluid medium to communicate between a macro-scale transceiver and micro-devices or to communicate between micro-devices. Acoustical transmission can be used to communicate data or to provide power to the micro-device(s). The ability to transmit and receive on multiple frequencies can optimize the transmission for a particular situation.

Abstract: The invention provides devices and methods for using acoustics to communicate between a macro-scale transceiver and a micro-device or between multiple micro-devices. The micro-devices may passively scatter sound from a transceiver or actively generate sound. Acoustic waves can also provide power to a micro-device.
