Patent number: 11074520Abstract: Systems and methods are disclosed for preparing and evolving atomic defects in diamond. Silicon vacancy spins may be cooled to temperatures equal to or below 500 mK to reduce the influence of phonons. The cooling, manipulation, and observation systems may be designed to minimize added heat into the system. A CPMG sequence may be applied to extend coherence times. Coherence times may be extended, for example, to 13 ms.Type: GrantFiled: August 10, 2018Date of Patent: July 27, 2021Assignee: President and Fellows of Harvard CollegeInventors: Denis D.

Publication number: 20140253684Abstract: A system and method for visualization of subsurface anatomy includes obtaining a first image from a first camera and a second image from a second camera or a second channel of the first camera, where the first and second images contain shared anatomical structures. The second camera and the second channel of the first camera are capable of imaging anatomy beneath the surface in ultra-violet, visual, or infra-red spectrum. A data processor is configured for computing registration of the first image to the second image to provide visualization of subsurface anatomy during surgical procedures. A visual interface displays the registered visualization of the first and second images. The system and method are particularly useful for imaging during minimally invasive surgery, such as robotic surgery.Type: ApplicationFiled: May 5, 2011Publication date: September 11, 2014Applicant: THE JOHNS HOPKINS UNIVERSITYInventors: Rajesh Kumar, Russell H.

Patent number: 8347267Abstract: An automated software testing system allows automated test script generation with fully parameterized scripts, execution, and result correlation. A software Application Under Test (AUT) includes a process having Graphical User Interface (GUI) windows, objects and data elements. A test thread tree is generated corresponding to these windows, objects and data elements. A data structure is generated to enumerate test cases indicative of the windows, objects and data elements. Also generated is a parameterized script implementing the test cases and having string values instead of hard-coded data. A global change manager automates modifying in the data structure, data object attributes across multiple scripts. A Scenario view or data generation member generates Test Descriptions, automatically documenting the test cases. The script is executed to apply each of the test cases to the AUT and receive responses.Type: GrantFiled: March 11, 2011Date of Patent: January 1, 2013Assignee: SmarteSoft, Inc.Inventors: Ethan Givoni, Naomi Ravitz, Ziv Ravitz, Thang Quoc Nguyen, Thieu Nguyen

Patent number: 7987150Abstract: Automated defect sourcing systems identify root-causes of yield excursions due to contamination, process faults, equipment failure and/or handling. They perform this function in timely manner and provide accurate and timely feedback to address and contain the sources of yield excursion. A signature repository stores known wafer surface manufacturing defect types as set of rules. The signature of a manufacturing defect pattern is associated with the equipment or process that causes the defects, and is used to source the manufacturing defects and to provide process control for changing and/or stopping yield excursion during fabrication. A defect signature rule-based engine matches wafer defects against the signature repository during wafer fabrication. Once the defect signature is detected during fabrication, handling and/or disposing the root-cause of the corresponding defect is facilitated using messages according to an event handling database.Type: GrantFiled: September 4, 2007Date of Patent: July 26, 2011Assignee: SIGLazInventors: Victor V.
