Patent number: 11638882Abstract: A wall-climbing vehicle having a bottom cover configured along a bottom portion. The bottom cover is disposed along the bottom portion such that a gap between the vertical wall and the bottom portion of the wall-climbing vehicle is formed. An air intake area is configured along a middle portion of the bottom cover to enable symmetrical weight balance. The air intake area is configured to accommodate a circular air intake arrangement that includes a circular configuration to create a large opening along the air intake area to increase an air suction volume along the air intake area. The wall-climbing vehicle includes a plurality of sealing cloths strips configured along sides the bottom portion to form a closed area in the wall-climbing vehicle to be continuously evacuated to form a negative pressure. Moreover, a plurality of bumps and a plurality of dots may be provided for balancing effect.Type: GrantFiled: April 26, 2020Date of Patent: May 2, 2023Inventor: Lixiong Wang

Patent number: 9223887Abstract: The invention provides self-organization methodologies and system for internet users to build web-based organizational hierarchical structure that is constituent of units within which direct and sufficient communication can be fulfilled. Each unit is administrated autonomously through the democratic-decision process, and processes information internally. The members of unit can designate or replace its leader anytime though election; the leader elect of a unit will then become a member of its direct upper unit in the structure, representing its unit to participate in the management and election of upper unit and to bring the consolidated results of its unit to the upper unit for further consolidation; recursively, a hierarchical structure is to form from bottom to upper progressively, and to produce different level of end products at different layer.Type: GrantFiled: August 18, 2011Date of Patent: December 29, 2015Inventor: Lixiong Wang
