Title: Engineered setpoints for autonomous distributed sensors and actuators

Abstract

Loads on an electric power system are configured with under-frequency relays in which the frequency setpoints and delay times for reclosure are uniformly distributed. If demand exceeds supply in the system, frequency will decrease. The decrease in frequency will actuate relays and reduce load to the point where demand will meet the available supply. After its engineered delay time, each relay will attempt to close contact and reestablish the load.

Autonomous sensor fish to support advanced hydropower development

Patent Deng, Z. Daniel; Myjak, Mitchell J.; Lu, Jun; ...

An improved sensor fish with robust design and enhanced measurement capabilities. This sensor fish contains sensors for acceleration, rotation, magnetic field intensity, pressure, and temperature. A low-power microcontroller collects data from the sensors and stores up to 5 minutes of data on a non-volatile flash memory. A rechargeable battery supplies power to the sensor fish. A recovery system helps locating sensor fish. The package, when ready for use is nearly neutrally buoyant and thus mimics the behavior of an actual fish.

Microscale autonomous sensor and communications module

Patent Okandan, Murat; Nielson, Gregory N

Various technologies pertaining to a microscale autonomous sensor and communications module are described herein. Such a module includes a sensor that generates a sensor signal that is indicative of an environmental parameter. An integrated circuit receives the sensor signal and generates an output signal based at least in part upon the sensor signal. An optical emitter receives the output signal and generates an optical signal as a function of the output signal. An energy storage device is configured to provide power to at least the integrated circuit and the optical emitter, and wherein the module has a relatively small diametermore » and thickness. « less

Multi-sensor fusion for robust autonomous flight in indoor and outdoor environments with a rotorcraft micro-aerial vehicle (MAV)

Patent Shen, Shaojie

The subject matter described herein includes a modular and extensible approach to integrate noisy measurements from multiple heterogeneous sensors that yield either absolute or relative observations at different and varying time intervals, and to provide smooth and globally consistent estimates of position in real time for autonomous flight. We describe the development of the algorithms and software architecture for a new 1.9 kg MAV platform equipped with an IMU, laser scanner, stereo cameras, pressure altimeter, magnetometer, and a GPS receiver, in which the state estimation and control are performed onboard on an Intel NUC 3rd generation i3 processor.
