Publication number: 20240071713Abstract: There is provided a charged particle apparatus comprising: a particle beam generator, optics, a first and a second positioning device, both configured for positioning the substrate relative to the particle beam generator along its optical axis, and a controller configured for switching between a first operational mode and a second operational mode. The apparatus is configured, when operating in the first operational mode, for irradiating the substrate by the particle beam at a first landing energy of the particle beam and, when operating in the second operational mode, for irradiating the substrate at a second, different landing energy. When operating in the first operational mode, the second positioning device is configured to position the substrate relative to the particle beam generator at a first focus position of the particle beam and in the second operational mode, to position the substrate at a second, different focus position.Type: ApplicationFiled: December 9, 2021Publication date: February 29, 2024Applicant: ASML Netherlands B.V.Inventors: Niels Johannes Maria BOSCH, Xu WANG, Peter Paul HEMPENIUS, Yongqiang WANG, Hans BUTLER, Youjin WANG, Jasper Hendrik GRASMAN, Jianzi SUI, Tianming CHEN, Aimin WU

Patent number: 8926121Abstract: A portable light with spectrum control means which allows the user to adjust the output spectrum manually and conveniently. The portable light includes compact housing with waterproof design and excellent heat dissipation, and it is preferably powered by batteries. A light source with multiple light-emitting units is aligned with light mixing and projecting components to produce light with uniform and consistent output synthetic spectra. Peripheral components, such as tactile switch, potentiometer, etc., and the electrical control circuit work together to respond to the user's actions to adjust the spectrum of the output light. The power management module regulates the electrical output of the power source to maintain a consistent light output as the power source drains.Type: GrantFiled: February 15, 2013Date of Patent: January 6, 2015Inventor: Youjin Wu

Patent number: 8752325Abstract: An apparatus is disclosed. The apparatus includes an adapter including a first body and a second body. A lower surface profile of the first body and the second body cooperate to form a first geometric mounting profile. An upper surface profile of the first body and the second body cooperate to form a second geometric mounting profile. The first geometric mounting profile is different from the second geometric mounting profile. Each of the first body and the second body forms at least one first aligned bore that receives a first fastener that connects the first body to the second body and a spring that biases the first body and the second body away from one another. An assembly is also disclosed. A method is also disclosed.Type: GrantFiled: October 17, 2011Date of Patent: June 17, 2014Assignee: Leapers, Inc.Inventors: Tai-Lai Ding, Youjin Wu

Patent number: 8437079Abstract: A scope is disclosed and includes a substantially tubular body having an inner surface and an outer surface. The scope includes a reticle, a light-emitting diode, and a circuit board including a processor having a program. The light-emitting diode is connected to the circuit board and the program controls the light-emitting diode to emit one of at least three user-selectable colored lights upon the reticle.Type: GrantFiled: May 6, 2011Date of Patent: May 7, 2013Assignee: Leapers, Inc.Inventor: Youjin Wu

Patent number: 8397421Abstract: A quick disconnect apparatus is disclosed. The quick disconnect apparatus includes a base member, a rail clamp member and a rail clamp adjustment device. The base member includes at least one passage. The rail clamp member includes a support bar receiving passage. The rail clamp member is movably-coupled to the base member. The rail clamp adjustment device is coupled to at least one of the base member and rail clamp member. The rail clamp adjustment device includes a pivot pin, a cam member including at least one offset passage and a support bar including a pivot-pin receiving passage. The support bar is inserted through the support bar receiving passage of the rail clamp member and a passage of the at least one passage of the base member to movably-couple the rail clamp member with the base member. The pivot pin is inserted through the at least one offset passage of the cam member and the pivot-pin receiving passage of the support bar to rotatably-couple the cam member relative the support bar.Type: GrantFiled: March 29, 2011Date of Patent: March 19, 2013Assignee: Leapers, Inc.Inventors: Tai-Lai Ding, Youjin Wu
