Patent number: 11715615Abstract: A light modulated electron source utilizes a photon-beam source to modulate the emission current of an electron beam emitted from a silicon-based field emitter. The field emitter's cathode includes a protrusion fabricated on a silicon substrate and having an emission tip covered by a coating layer. An extractor generates an electric field that attracts free electrons toward the emission tip for emission as part of the electron beam. The photon-beam source generates a photon beam including photons having an energy greater than the bandgap of silicon, and includes optics that direct the photon beam onto the emission tip, whereby each absorbed photon creates a photo-electron that combines with the free electrons to enhance the electron beam's emission current. A controller modulates the emission current by controlling the intensity of the photon beam applied to the emission tip. A monitor measures the electron beam and provides feedback to the controller.Type: GrantFiled: July 6, 2022Date of Patent: August 1, 2023Assignee: KLA CorporationInventors: Edgardo Garcia Berrios, J.

Patent number: 10346523Abstract: Techniques and solutions are described for content synchronization across devices. A web page currently being viewed at a first device associated with a user profile of a user can be identified. Browsing information for the page (such as URL, scrolling location, and a DOM element) may be stored in the profile. The DOM element may be associated with page content displayed during a browsing session in a viewport while the web page is at the current scrolling location. The browsing information may be updated dynamically, upon detecting a change in the current scrolling location of the page at the first device. A request for displaying the web page at a second device associated with the user profile may be received. The browsing information for the web page may be provided to the second device, so that the web page with the current scrolling location is displayed at the second device.Type: GrantFiled: October 10, 2017Date of Patent: July 9, 2019Assignee: Amazon Technologies, Inc.Inventors: Patrick Joseph Armstrong, Yousef Zachary Khwaja, Sajeeva Lakmal Bandara Pallemulle, Vincent Roseberry, Arun Sundaram, Ameet Nirmal Vaswani, Leonardo Davi Viccari, Li Yan

Patent number: 10296580Abstract: Systems and methods are described that relate to processing content, such as web pages, to be rendered and displayed on client computing devices. In one embodiment, a content parsing system may retrieve a content item on behalf of a client computing device, and parse markup language within the content item to generate a binary representation of objects within the content item. The content parsing system may then serialize the binary representation, and transmit the binary representation to the client computing device. The client computing device can then utilize the binary representation to output the content item, without parsing at least a portion of the content item.Type: GrantFiled: September 18, 2015Date of Patent: May 21, 2019Assignee: Amazon Technologies, Inc.Inventors: Venkata Sri Krishnakanth Pulla, Andrew Kenneth Milton, Kenneth Thomas Brown, Patrick Joseph Armstrong, Yasaswi Vempati

Patent number: 10199149Abstract: A laser assembly for generating laser output light at an output wavelength of approximately 183 nm includes a fundamental laser, an optical parametric system (OPS), a fifth harmonic generator, and a frequency mixing module. The fundamental laser generates fundamental light at a fundamental frequency. The OPS generates a down-converted signal at a down-converted frequency. The fifth harmonic generator generates a fifth harmonic of the fundamental light. The frequency mixing module mixes the down-converted signal and the fifth harmonic to produce the laser output light at a frequency equal to a sum of the fifth harmonic frequency and the down-converted frequency. The OPS generates the down-converted signal by generating a down-converted seed signal at the down-converted frequency, and then mixing the down-converted seed signal with a portion of the fundamental light.Type: GrantFiled: July 26, 2017Date of Patent: February 5, 2019Assignee: KLA-Tencor CorporationInventors: Yung-Ho Alex Chuang, J.

Patent number: 10193293Abstract: A pulse multiplier includes a polarizing beam splitter, a wave plate, and a set of multi-surface reflecting components (e.g., one or more etalons and one or more mirrors). The polarizing beam splitter passes input laser pulses through the wave plate to the multi-surface reflecting components, which reflect portions of each input laser pulse back through the wave plate to the polarizing beam splitter. The polarizing beam splitter reflects each reflected portion to form an output of the pulse multiplier. The multi-surface reflecting components are configured such that the output pulses exiting the pulse multiplier have an output repetition pulse frequency rate that is at least double the input repetition pulse frequency.Type: GrantFiled: April 9, 2018Date of Patent: January 29, 2019Assignee: KLA-Tencor CorporationInventors: Yung-Ho Chuang, J.

Patent number: 10095663Abstract: A system and process are disclosed for providing users with page previews during page loading events, such that the delay experienced before the display of page content is reduced. The previews may include screenshots of the pages or of portions thereof, and may be generated periodically and cached by the system for delivery to user devices. The process of generating and delivering the previews via the Internet or some other network may be implemented partly or wholly within an intermediary system that sits logically between the user devices and content servers. The process may be used with existing browsers without the need for any browser modifications, or may be used with a “preview-aware” browser that includes special program code for providing page previews.Type: GrantFiled: March 15, 2013Date of Patent: October 9, 2018Assignee: Amazon Technologies, Inc.Inventors: Rohit Krishna Kumar, Scott Zachary Bressler, Ivan King Yu Sham, Ian William Stewart, Brett Richard Taylor, Peter Frank Hill, Aakarsh Nair, Steven Michael Reddie, Patrick Joseph Armstrong, Samuel John Young, Ameet Nirmal Vaswani, Andrew Lynch Hayden

Patent number: 10044164Abstract: A repetition rate (pulse) multiplier includes one or more beam splitters and prisms forming one or more ring cavities with different optical path lengths that delay parts of the energy of each pulse. A series of input laser pulses circulate in the ring cavities and part of the energy of each pulse leaves the system after traversing the shorter cavity path, while another part of the energy leaves the system after traversing the longer cavity path, and/or a combination of both cavity paths. By proper choice of the ring cavity optical path length, the repetition rate of an output series of laser pulses can be made to be a multiple of the input repetition rate. The relative energies of the output pulses can be controlled by choosing the transmission and reflection coefficients of the beam splitters. Some embodiments generate a time-averaged output beam profile that is substantially flat in one dimension.Type: GrantFiled: August 17, 2016Date of Patent: August 7, 2018Assignee: KLA-Tencor CorporationInventors: Yung-Ho Alex Chuang, Xiaoxu Lu, Justin Dianhuan Liou, J.

Patent number: 10021195Abstract: Features are disclosed for synchronizing information across various devices, and using the synchronized information during subsequent content interactions. Devices may receive and/or store information, such as cookies or other account-level information, in connection with content interactions, such as content page retrieval, application execution, and the like. Information that is not device-specific can be synchronized across multiple devices, thus providing access to the information on any of the devices regardless of which device originally received or stored the information.Type: GrantFiled: August 14, 2017Date of Patent: July 10, 2018Assignee: Amazon Technologies, Inc.Inventor: Patrick Joseph Armstrong
