Abstract: A LiDAR is provided. The LiDAR includes two laser emission modules and one laser receiving module. The two laser emission modules are located separately on opposite sides of the laser receiving module, and a combination of emission fields of view of the two laser emission modules matches a receiving field of view of the laser receiving module.

Abstract: An integrated multi-scale modeling platform is utilized to assess agricultural productivity and sustainability. The model is used to assess the environmental impacts of agricultural management from individual fields to watershed/basin to continental scales. In addition, an integrated irrigation system is developed using data and a machine-learning model that includes weather forecast and soil moisture simulation to determine an irrigation amount for farmers. Next, crop cover classification prediction can be established for an ongoing growing system using a machine learning or statistical model to predict the planted crop type in an area. Finally, a method of predicting key phenology dates of crops for individual field parcels, farms, or parts of a field parcel, in a growing season, can be established.

Abstract: The utility model relates to an electric driver and an illumination device. The electric driver comprises: a carrier; a first electrical component and a second electrical component, wherein the first electrical component and the second electrical component are provided on the carrier; and a heat insulation structure, wherein the second electrical component comprises a first heat insulator surrounding the second electrical component and a second heat insulator surrounding the first heat insulator, wherein a gap is provided between the first heat insulator and a second heat insulator. The electric driver according to the present utility model improves the lifetime of capacitors, is low-cost, and has a compact structure.
