The sewage treatment biological agent according to an embodiment of the present invention includes an induced nucleus. The induced nucleus has good bioaffinity. A microbial flora can be attached to the induced nucleus to achieve rapid growth. As the microbial flora gathers and grows on the induced nucleus, the granulation is gradually achieved by the sewage treatment biological agent to facilitate the sewage treatment. The microbial flora grows on the induced nucleus, and the growth process of microbial flora is a covering growth process which starts from the induced nucleus and gradually expands outward and centers on the induced nucleus. During the growth of microbial flora, extracellular polymers are secreted, which can further promote the granulation process by the sewage treatment biological agent.Type: ApplicationFiled: October 9, 2022Publication date: August 10, 2023Applicant: Hunan Sanyou Environmental Protection Technology Co.

Patent number: 8611643Abstract: Photographs of an object may be oriented with respect to both the geographic location and orientation of the object by registering a 3D model derived from a plurality of photographs of the objects with a 2D image of the object having a known location and orientation. For example, a 3D point cloud of an object created from photographs of the object using a Photosynthâ„¢ tool may be aligned with a satellite photograph of the object, where the satellite photograph has location and orientation information. A tool providing scaling and rotation of the 3D model with respect to the 2D image may be used or an automatic alignment may be performed using a function based on object edges filtered at particular angles. Once aligned, data may be recorded that registers camera locations for the plurality of photographs with geographic coordinates of the object, either absolute latitude/longitude or relative to the object.Type: GrantFiled: September 14, 2012Date of Patent: December 17, 2013Assignee: Microsoft CorporationInventors: Eyal Ofek, Dan Hou, Blaise Aguera y Arcas, Scott Vernon Fynn, Roberto R.
