Abstract: An energy harvester for use in-line with a pipe to harness potential and kinetic energy of fluids flowing therein. Structure for the energy harvester may include a shaft and a blade extending radially therefrom. The shaft can penetrate a housing that operates as a pipe section to install the device in-line with pipe. The shaft can couple with an electrical generator. A load may connect with voltage terminals on the generator so that fluid impinging on the blades will rotate the generator to power the load, effectively harvesting power from the flowing fluid. In one implementation, a load control device that couples with the generator voltage terminals controls a pressure characteristic of the fluid, such as pressure drop, by applying an electrical load on the generator and controllably impeding rotation of the shaft.

Title: Lidar based 3-d imaging with varying pulse repetition
Inventor: HALL DAVID S
IPC: G01C3/00
Filed: 2017-03-20
Abstract: Methods and systems for performing three dimensional LIDAR measurements with different pulse repetition patterns are described herein. Each repetitive pattern is a sequence of measurement pulses that repeat over time. In one aspect, the repetition pattern of a pulsed beam of illumination light emitted from a LIDAR system is varied to reduce total energy consumption and heat generated by the LIDAR system. In some examples, the repetitive pattern is varied by skipping a number of pulses. In some examples, the repetitive pattern of pulses of illumination light emitted from the LIDAR system is varied by changing a repetition rate of the sequence of emitted pulses. In some examples, the pulse repetition pattern is vared based on the orientation of the LIDAR device. In some examples, the repetition pattern is varied based on an object detected by the LIDAR device or another imaging system.
