Title: System for constructing urban design digital sandbox
Inventor: YANG JUNYAN
IPC: G06T17/10
Filed: 2018-06-06
Abstract: A system for constructing an urban design digital sandbox, the system comprising the following modules: a sandbox environment construction module (1), used for digital environment construction of an urban design sandbox; an element grading display module (2), which hierarchically manages urban design elements and performs visualized hierarchical display; a spatial indicator interpretation module (3), which links the names, algorithms and attributes of indicators in an urban design digital sandbox indicator library; a spatial calculation tool module (4), which calculatesa selected range loading toolkit in the digital sandbox; an offline data extraction module (5), which extracts digital sandbox data in an offline mode and is used for exporting two-dimensional or three-dimensional spatial data; and a dynamic instant editing module (6), used for carrying out real-time editing operations on an urban digital design scheme loaded in the system. The present system may easily introduce urban design schemes into a digital city environment and provide a platform and safeguard for the digital research, analysis and management, and control of urban design.

Title: Foldable propeller and unmanned aerial vehicle
Inventor: LI YANG
IPC: B64C11/28
Filed: 2018-06-27
Abstract: A foldable propeller, comprising a first blade (20), a second blade (30), a mounting seat (10), and an anti-swing member. The mounting seat (10) is rotatably connected to a driving mechanism of an unmanned aerial vehicle; one end of the first blade (20) and one end of the second blade (30) are rotatably connected onto the mounting seat (10); the driving mechanism drives the mounting seat (10) to rotate, so as to drive the first blade (20) and the second blade (30) to rotate around a rotating center of the mounting seat (10); the anti-swing member is used for applying pressure or tension to the first blade (20) and the second blade (30), so that a connection relationship is established between the first blade (20) and the second blade (30), and positions of the first blade (20) and the second blade (30) are limited. Also disclosed is an unmanned aerial vehicle. A force relationship can be established between the first blade (20) and the second blade (30) by providing the anti-swing member, the swing of the first blade (20) or the second blade (30) is weakened or even eliminated, so that the flight of the unmanned aerial vehicle is more stable.
