Patent number: 10568981Abstract: UV hard-surface disinfection system that is able to disinfect the hard surfaces in a room, while minimizing missed areas due to shadows by providing multiple UV light towers that can be placed in several areas of a room such that shadowed areas are eliminated and that can be transported by a cart that is low to the ground such that the towers may be loaded and unloaded easily by a single operator. The system is able to be controlled remotely, such that during activation of the system, no operator is present, and to automatically cut power to all towers in the event that a person enters the room.Type: GrantFiled: September 7, 2018Date of Patent: February 25, 2020Assignee: Surfacide, LLCInventors: Waldemar John Lyslo, Mark Howard Schwartz, Stephen Boyd Pettis

Patent number: 9810713Abstract: Methods and apparatuses are provided for automatically controlling and stabilizing aspects of a scanning probe microscope (SPM), such as an atomic force microscope (AFM), using Peak Force Tapping (PFT) Mode. In an embodiment, a controller automatically controls periodic motion of a probe relative to a sample in response to a substantially instantaneous force determined, and automatically controls a gain in a feedback loop. A gain control circuit automatically tunes a gain based on separation distances between a probe and a sample to facilitate stability. Accordingly, instability onset is quickly and accurately determined during scanning, thereby eliminating the need of expert user tuning of gains during operation.Type: GrantFiled: March 1, 2016Date of Patent: November 7, 2017Assignee: Bruker Nano, Inc.Inventors: Jian Shi, Yan Hu, Shuiqing Hu, Ji Ma, Chanmin Su

Patent number: 9466457Abstract: Ordinary charged particle beam apparatuses have each been an apparatus manufactured for dedicated use in making observations in a gas atmosphere at atmospheric pressure or at a pressure substantially equal thereto. There have existed no devices capable of simply making observations using an ordinary high-vacuum charged particle microscope in a gas atmosphere at atmospheric pressure or at a pressure approximately equal thereto. Furthermore, ordinary techniques have been incapable of observing the same spot of the sample in such an atmosphere using a charged particle beam and light simultaneously.Type: GrantFiled: July 1, 2013Date of Patent: October 11, 2016Assignee: Hitachi High-Technologies CorporationInventors: Yusuke Ominami, Mami Konomi, Shinsuke Kawanishi, Sukehiro Ito

Patent number: 8320646Abstract: An MRI system produces a three-dimensional image by acquiring NMR signals that fully sample a central region of k-space and partially sample peripheral k-space as a set of asymmetric radial sectors. The NMR signals are acquired with a plurality of receive channels and coils. An image is reconstructed using a homodyne reconstruction combined with SENSE processing.Type: GrantFiled: May 2, 2006Date of Patent: November 27, 2012Assignee: MAYO Foundation for Medical Education and ResearchInventors: Houchun H. Hu, Ananth J. Madhuranthakam, Stephen J. Riederer

Patent number: 7428347Abstract: The invention includes an optical signal transmission transducer. The optical signal transmission transducer includes a magnetic tunnel junction. The magnetic tunnel junction can be tuned to switch states in response to selected frequencies of a magnetic field. A light source can be modulated based upon states of the magnetic tunnel junction. An alternate embodiment of the optical signal transmission transducer includes a light transducer that generates magnetic sense signals based upon reception of modulated light signals. The light transducer can be integrated with a magnetic tunnel junction. The magnetic tunnel junction can be tuned to switch states in response to selected frequencies of the magnetic sense signal.Type: GrantFiled: April 16, 2003Date of Patent: September 23, 2008Assignee: Samsung Electronics Co., Ltd.Inventors: Manish Sharma, Manoj K. Bhattacharyya

Patent number: 6970620Abstract: In the region of a distal end at its circumference the waveguide is formed transparent to the radiation which impinges onto the surface of the waveguide at suitable angles, and in the region of the distal end in the inside of the waveguide there are arranged scatter elements which scatter radiation transmitted by the waveguide in the direction of the distal end in a direction with a proximally directed component which exits the circumference of the waveguide. Alternatively, radiation entering into the waveguide at the circumference of the waveguide in a direction with a distally directed component is transmitted by the waveguide in the direction of the proximal end, as well as to its use and to a method for its manufacture.Type: GrantFiled: April 3, 2003Date of Patent: November 29, 2005Assignee: Richard Wolf GmbHInventors: Lars Ziegenhagen, Gereon Hüttmann

Patent number: 6947622Abstract: An optical device having one or more optical components is disclosed. A waveguide extends from an optical component to a testing port configured to receive a light signal from a position over the optical device and to insert the light signal into the waveguide. In some instances, the testing port is configured to receive a light signal from the waveguide and to direct the light signal to a location over the optical device. The optical device can be positioned on a wafer before being separated from the wafer. The waveguide can extend from an optical component over the perimeter of the optical device such that the testing ports are located outside the perimeter of the optical device.Type: GrantFiled: June 27, 2002Date of Patent: September 20, 2005Assignee: Kotura, Inc.Inventors: Liwei Wang, Dazeng Feng, Xiaoming Yin, Trenton Gary Coroy
