Patent number: 9645064Abstract: An example method includes positioning a mass at a height opposite a modulator characterized by a particular strain rate and support by a carrier moveably disposed opposite the mass. The method also includes releasing the mass such that the mass impacts the modulator, and an additional component connected to the carrier causes failure of a sample of material. The method further includes determining a displacement of the carrier corresponding to failure of the sample, determining a force applied to the modulator by the mass and resulting in failure of the sample, and determining at least one of a dynamic strength of the sample and a dynamic modulus of the sample. In such a method, the dynamic strength is based on the force applied to the modulator and the strain rate. Additionally, the dynamic modulus is based on the displacement of the carrier and the strain rate.Type: GrantFiled: March 9, 2015Date of Patent: May 9, 2017Assignee: Amazon Technologies, Inc.Inventors: Mohammed Aftab Alam, Ramez Nachman, Shankar Ganapathysubramanian, Guruprasad Ramanathan

Patent number: 9645125Abstract: A method of measuring an atmosphere in a guest vacuum chamber of a vacuum tool includes measuring a first composition of the atmosphere in the host vacuum chamber using a residual gas analyzer (RGA). The host and guest vacuum chambers are not coupled during the measuring of the first composition. The host vacuum chamber is coupled to the guest vacuum chamber, so the atmospheres in each can mix in the host vacuum chamber. A second composition of the atmosphere in the host vacuum chamber is measured using the RGA after the chambers are coupled. Using a processor, a composition of the guest atmosphere is automatically determined using the measured first and second compositions. A vacuum tool can include the host and guest chambers, the valve, the RGA, and a processor configured to control the valve to carry out this or other methods.Type: GrantFiled: December 4, 2013Date of Patent: May 9, 2017Assignee: INFICON, INC.Inventor: Chenglong Yang

Patent number: 9632100Abstract: A host system recognizes a sample pretreatment system at which a primary sample has first arrived and records the information, if multiple containers containing the primary sample are input. Upon issuing an analysis request to the sample pretreatment system, the host system determines whether the primary sample (sample bearing the same barcode for sample identification) is input to a system different from the system to which the sample was input for the first time and, if that is the case, then determines that “the sample is input to the wrong system” and issues a “do-nothing request” (request to do nothing) so that an aliquoting operation will not be performed. Given the “do-nothing request” from the host system, the sample pretreatment system does not prepare any aliquot sample and places the input sample onto a tray in a predetermined position.Type: GrantFiled: December 18, 2012Date of Patent: April 25, 2017Assignee: Hitachi High-Technologies CorporationInventors: Iwao Suzuki, Tadao Shimizu, Shigeru Yano, Koji Kamoshida

Patent number: 9632064Abstract: An injection port for a gas chromatograph (GC) is operated such that, during an injection sequence, an inert gas is used for sample transfer to the analytical column while hydrogen is subsequently utilized for the majority of the analytical separation. This allows for a high degree of chromatographic efficiency, while also reducing unwanted chemical reactions involving hydrogen and/or reactive solvents in a hot injection port. Certain embodiments also provide an increased margin of safety when using hydrogen, since the total flow may be limited such that the concentration of hydrogen in the GC oven never exceeds a safety limit, such as the lower explosive limit.Type: GrantFiled: July 17, 2014Date of Patent: April 25, 2017Assignee: Thermo Finnigan LLCInventors: Edward B. McCauley, Franco Ponciroli, Paolo Magni

Patent number: 9618417Abstract: Improved gas leak detection from moving platforms is provided. Automatic horizontal spatial scale analysis can be performed in order to distinguish a leak from background levels of the measured gas. Source identification can be provided by using isotopic ratios and/or chemical tracers to distinguish gas leaks from other sources of the measured gas. Multi-point measurements combined with spatial analysis of the multi-point measurement results can provide leak source distance estimates. These methods can be practiced individually or in any combination.Type: GrantFiled: October 19, 2012Date of Patent: April 11, 2017Assignee: Picarro, Inc.Inventors: Chris W. Rella, Eric R.

Patent number: 9610597Abstract: A system and method for tagging, tracking, locating and identifying people and vehicles transporting people using Perfluorocarbon tracers. An on-going problem faced by military as well as law enforcement personnel is that of friendly fire incidents. To prevent possible friendly-fire incidents, troops would separate the two layers of the uniform patch, thereby releasing a controlled release of the Perfluorocarbon vapors. Other “friendly” troops, equipped with sensors tuned to the specific perfluorocarbon characteristics would thus be able to literally view a plume around the tagged person or object. The system may conversely be used to tag enemies. Formulations of mixed perfluorocarbons may be used to provide coding of emissions.Type: GrantFiled: June 15, 2015Date of Patent: April 4, 2017Assignee: Copilot Ventures Fund III LLCInventor: Jay Fraser
