Publication number: 20200222723Abstract: A method and system for using in a two-modality apparatus. The two-modality apparatus comprises a couch with a table top, a first modality unit and a second modality unit. A second image of a target portion of an object when the table top is at a second working position of the second modality unit may be acquired. A second sag of the table top at a second measurement point of the table top according to the second image may be determined based on the image.

Patent number: 10347996Abstract: An electrical connector includes a barrel type terminal, having a first connecting area and a second connecting area. The first connecting area has a first non-soldering surface and a first soldering surface. The second connecting area has a second non-soldering surface and a second soldering surface. Each of the first and second soldering surfaces and the first and second non-soldering surfaces has a first solder layer. A sleeve sheathes outside the barrel type terminal, and has a first fixing area and a second fixing area. Two second solder layers are provided between the first fixing area and the first soldering surface and between the second fixing area and the second soldering surface. The amount of solder provided between the first fixing area and the first soldering surface and between the second fixing area and the second soldering surface is greater than that provided on the first and second non-soldering surfaces.Type: GrantFiled: October 16, 2018Date of Patent: July 9, 2019Assignee: LOTES CO., LTDInventors: Yung Sheng Kung, Lu Xu, Jian Wei Gong

Patent number: 10320130Abstract: A barrel terminal has one end for inserting a mating member and the other end for connecting a cable. The barrel terminal includes a contact portion, a connecting portion, and a buffer portion connecting the contact portion and the connecting portion. The contact portion has multiple contact elastic pieces, and the contact elastic pieces are used for electrically contacting the mating member. The connecting portion is used for connecting the cable. The buffer portion has multiple absorption portions. The absorption portions absorb the deformation stress of the connecting portion to prevent the stress from being transferred to the contact portion, to avoid the deformation of the contact elastic pieces, so as not to cause the reduction of the contact area between the contact elastic pieces and the abutment terminal, and to prevent reduction of a clamping force of the barrel terminal to the mating member.Type: GrantFiled: August 21, 2017Date of Patent: June 11, 2019Assignee: LOTES CO., LTDInventor: Lu Xu

Publication number: 20190067504Abstract: Luminescent solar concentrators in accordance with various embodiments of the invention can be designed to minimize photon thermalization losses and incomplete light trapping using various components and techniques. Cadmium selenide core, cadmium sulfide shell (CdSe/CdS) quantum dot (“QD”) technology can be implemented in such devices to allow for near-unity QDs and sufficiently large Stokes shifts. Many embodiments of the invention include a luminescent solar concentrator that incorporates CdSe/CdS quantum dot luminophores. In further embodiments, anisotropic luminophore emission can be implemented through metasurface/plasmonic antenna coupling. In several embodiments, red-shifted luminophores are implemented. Additionally, top and bottom spectrally-selective filters, such as but not limited to selectively-reflective metasurface mirrors and polymeric stack filters, can be implemented to enhance the photon collection efficiency.Type: ApplicationFiled: August 27, 2018Publication date: February 28, 2019Applicants: California Institute of Technology, The Regents of the University of California, The Board of Trustees of the University of lllinoisInventors: David R.
