Patent number: 11579056Abstract: A universal material tester with two or more consecutively arranges test units has a test tool supporting carriage, which is provided with a removable partition that allows conversion of the test-unit installation socket from a multiple test unit holder into a single test-unit holder, or vice versa. An advantage of the tester is a possibility of expanding dynamic range of measurements by using two or more test units, which are installed in series at one setting and can be used in sequential tests without replacement but with different measurement ranges. This broadens the dynamic measurement ranges and allows revealing material properties otherwise unattainable. The test units may be combined with an imaging device installed in series with the test tools that engage the sample physically.Type: GrantFiled: June 16, 2020Date of Patent: February 14, 2023Inventors: Gautam Char, Nick Doe, Vishal Khosla, Ming Chan, Michael Vinogradov-Nurenberg, Jun Xiao

Publication number: 20230013131Abstract: A novel shoulder brace that can provide active dynamic support to an injured shoulder while providing the capability to also raise the attached arm and support the arm in an elevated position. The brace can be used both in conjunction with a rehabilitation intervention program to maintain or restore range of motion and strength and to assist in functional tasks at work and at home. The brace works by supporting a locking or ratchet mechanism connected to an arm cuff from a chest piece that, when desired, the user can move the arm connected to an injured shoulder and supported by the arm cuff from a normal side resting position to an elevated position 90 degrees from the resting position while transferring the load created by the arm and whatever the hand is holding back to the chest piece and to the torso of the user. A release mechanism can be used to release the locking or ratchet mechanism to let the user lower their arm back to a resting position.Type: ApplicationFiled: July 16, 2021Publication date: January 19, 2023Inventors: Ming CHAN, Taylor MURPHY, Dhruvi DAVE, Jim TOLLER, Mark Vernon FEDORAK, Liam Joseph ABRAMS

Publication number: 20220196525Abstract: Proposed are a method and apparatus for maintaining constancy of force in contact between a test probe and test object, which are in a state of relative motion, e.g., in a material testing machine. This is achieved by providing the material testing machine with a leveling stage that includes an adjustable leveling mechanism for eliminating deviations of the support surface of the test sample table from flatness and parallelism to a reference plane that passes through the point of contact of the probe with the object perpendicular to the test probe. The mechanism includes springing elements and thrust elements that pass through the carrier member and rest against the springing elements for adjusting thrust forces applied to the springing elements for adjusting a position of the sample supporting surface relative to a virtual reference plane, which passes through the contact point perpendicular to the longitudinal axis of the probe.Type: ApplicationFiled: December 18, 2020Publication date: June 23, 2022Inventors: Vishal Khosla, Nick Doe, Ming Chan, Michael Vinogradov-Nurenberg, Jun Xiao, Gautam Char

Patent number: 10985998Abstract: A managed directory service receives a request to add a domain controller to a directory. In response to the request, the managed directory service determines, based on locations of other domain controllers of the directory, a location for the domain controller. The managed directory service provisions the domain controller at the location and associates the domain controller to the directory. The domain controller is activated in order to perform directory operations for the directory.Type: GrantFiled: May 21, 2018Date of Patent: April 20, 2021Assignee: Amazon Technologies, Inc.Inventors: Sachin Sanjay Gujar, Nitish Goyal, Ming Chan

Patent number: 10354255Abstract: A client tracking mechanism has a log file analysis routine that may generate two tables, one having a licensable entity designator and last logged off time, and the other having a current session designator. The first table may be aggregated by a server that may collect data from multiple client tracking mechanisms to determine a licensable entity's sessions across multiple servers. The client tracking mechanism may save and resume analysis from the last analyzed log file entry, and may be able to track sessions that are both shorter and longer than the time between each analysis. In many embodiments, a licensable entity may be a user or a device, when a license arrangement is configured in a per-user or per-device basis.Type: GrantFiled: January 9, 2008Date of Patent: July 16, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Ming Chan, Mark Sterin, Jagadeesh Kalki

Patent number: 10258239Abstract: Proposed is a method for in-line testing and surface analysis of test material with participation of Raman spectroscopy wherein the apparatus has a column with a plurality of test units at least one of which is a wear test unit and another is a Raman spectrometer. The sample is located on a rotary table under the test units. By sequentially removing the material of the sample to a predetermined depth and then conducting the surface analysis with the use of the Raman spectrometer, it becomes possible to analyze distribution of the material components in the depth direction from the surface of the sample.Type: GrantFiled: May 30, 2017Date of Patent: April 16, 2019Inventors: Vishal Khosla, Nick Doe, Ming Chan, Jun Xiao, Gautam Char

Patent number: 10215675Abstract: The sensor unit of the material tester consists of a pressure-sensor unit that measures a vertical force applied to the test probe during movement of the test probe relative to the test specimen and a horizontal force sensor unit for measuring the horizontally directed friction force. The horizontal force sensor unit is made in the form of a flexible parallelogram consisting of two sensor-holding plates interconnected through flexible beams, wherein one end of the first beam is attached to the upper sensor-holding plate and the opposite end to the lower sensor-holding plate, while one end of the second beam is attached to the lower sensor-holding plate and the other to the upper one. The beams are installed with gaps relative to both plates. The quick-release test probe incorporates a soft-touch feature.Type: GrantFiled: September 5, 2016Date of Patent: February 26, 2019Inventors: Vishal Khosla, Nick Doe, Jun Xiao, Ming Chan, Gautam Char

Patent number: 10179386Abstract: Proposed is a torque measurement tester for testing hole-treating rotary tools used on hole treating operations such as drilling, tapping, reaming, countersinking, or the like under real operation conditions for determining the most optimal operations parameters. The torque measurement unit consists of a package of three sensor units, in which the first unit is connected to the frame of the tester via pressure sensors for measuring a thrust force acting in the Z-axis direction, the second sensor unit measures forces acting on the tool in the direction of the X-axis, and the third sensor unit measures forces acting in the Y-axis direction. All measurements are carried out irrespective of each other without mutual effect on the measurement data. The third unit resiliently supports the rotary tool relative to the second unit, while the second unit is connected to the first sensor unit.Type: GrantFiled: December 24, 2016Date of Patent: January 15, 2019Inventors: Vishal Khosla, Nick Doe, Jun Xiao, Ming Chan, Gautam Char

Patent number: 10180367Abstract: Proposed is a method of determining optimal operation conditions for treating holes with a rotary tool by performing a hole treatment operation on a tester under various treatment conditions which are similar to the use of the tool in the industrial production on a real manufacturing equipment. The method consists of changing the treatment conditions and determining those operation parameters at which the treated hole is most optimally satisfies the given technical requirements. A criterion for evaluation of these optimal conditions is equality of pair forces acting on the rotary tool in the X- and Y-axis directions since such a situation prevents sidewise deviation of the tool from the direction of the thrust force applied in the Z-axis direction. The above condition is provided by the specific structure of the tester used for carrying out the method.Type: GrantFiled: December 24, 2016Date of Patent: January 15, 2019Inventors: Vishal Khosla, Nick Doe, Jun Xiao, Ming Chan, Gautam Char
