Patent number: 10458450Abstract: A probe head of a coordinate measuring machine (‘CMM”) includes a sensor to detect impact of the probe head with a foreign object. The probe head is movably coupled to the CMM such that the sensor detects motion of the probe head relative to a portion of the CMM resulting from an impact event. Some embodiments cause the CMM to take action in response to detecting an impact. Probe clips allow adjustment of the position of a CMM probe relative to the portion of the CMM from which the probe is suspended. This allows the position and orientation of the CMM probe to be adapted to a variety of applications.Type: GrantFiled: March 16, 2017Date of Patent: October 29, 2019Assignee: Hexagon Metrology, Inc.Inventors: Gurpreet Singh, Paul Racine, John Langlais, Jie Zheng

Patent number: 10352340Abstract: A probe clip allows easy and accurate placement of a probe clip onto a coordinate measuring machine (“CMM”). Moreover various probe clips are configured to movably and adjustably secure an optical probe to the CMM. To that end, the probe clip may have a probe seat, for holding the probe, movably coupled to a clamp segment by an adjustable joint. The clamp segment movably couples the probe seat to a probe platform on the CMM.Type: GrantFiled: March 16, 2017Date of Patent: July 16, 2019Assignee: Hexagon Metrology, Inc.Inventors: Gurpreet Singh, Paul Racine, John Langlais, Jie Zheng

Patent number: 10323920Abstract: A coordinate measuring machine has a base for supporting an object, a movable assembly having a probe for measuring the object, and a rail movably guiding the movable assembly along its length. The rail includes carbon fiber and has a rail CTE. The coordinate measuring machine also has an air bearing member circumscribing the rail and fixedly coupled with the movable assembly. The air bearing member has a member CTE, which is about equal to the rail engineered CTE.Type: GrantFiled: April 25, 2017Date of Patent: June 18, 2019Assignee: Hexagon Metrology, Inc.Inventors: Gurpreet Singh, John Langlais, Jie Zheng, Joseph G.

Publication number: 20160171179Abstract: Systems and methods for investigating the spread of pathogens at a site are provided. Flow data indicating an identity and location of objects at the site and movement of the objects within the site over time is acquired. Sampling data indicating a presence of pathogens on the objects over time and an identity of pathogens that are present is acquired. A computing device receives and evaluates the flow data and the sampling data. Based on evaluating the flow data and the sampling data, the computing device generates a graphical indicator that is informative of movement of the identified pathogens within the site over time and is visually presented for display.Type: ApplicationFiled: December 10, 2015Publication date: June 16, 2016Applicant: NSF InternationalInventors: Robert Scott Donofrio, Kurtis Richard Kneen, Peter John Langlais, Sireesha Mandava

Patent number: 9222763Abstract: A coordinate measuring machine has a measuring member for measuring a workpiece, a counterweight to control movement of the measuring member, and a pulley and cable system coupling the measuring member with the counterweight. The coordinate measuring machine also has a guide track, where the counterweight is movably secured to the guide track. The guide track substantially limits counterweight movement, relative to the measuring member, to one dimension.Type: GrantFiled: March 1, 2013Date of Patent: December 29, 2015Assignee: Hexagon Metrology, Inc.Inventors: Gurpreet Singh, John Langlais, Jie Zheng

Patent number: 8973279Abstract: A coordinate measuring machine has 1) an anchor beam with a top end and a bottom end, 2) at least one support beam having a top end and a bottom end, and 3) a cross-beam supported on the top ends of both the anchor beam and the at least one support beam. In addition, the coordinate measuring machine also has 4) a base supporting the bottom ends of the anchor beam and the at least one support beam. At least one of the at least one support beams has a first spring and a second spring. In preferred embodiments, the first spring is adapted to allow movement and is spaced from the second spring in a direction that is generally parallel with the longitudinal axis of the cross-beam.Type: GrantFiled: March 1, 2013Date of Patent: March 10, 2015Assignee: Hexagon Metrology, Inc.Inventors: Gurpreet Singh, John Langlais, Jie Zheng

Patent number: 8826719Abstract: A calibration artifact includes an elongated body made substantially entirely of ceramic material and having a direction of elongation. A plurality of measurement elements comprising the ceramic material are integrally formed with the elongated body, each measurement element comprising a first planar measurement surface facing in a first direction. The first planar measurement surface of each measurement element is parallel to the first planar measurement surface of each of the other measurement elements of the plurality of measurement elements. The calibration artifact may be a unitary step gauge formed with a single piece of ceramic material.Type: GrantFiled: December 14, 2011Date of Patent: September 9, 2014Assignee: Hexagon Metrology, Inc.Inventors: Wilhelmus Weekers, John Langlais, David Harvey, Peter Hicks

Patent number: 7191541Abstract: A machine, such as a coordinate measuring machine, having a component or element movable with respect to a support structure along rails or guideways, wherein the rails have a coefficient of thermal expansion that is different from that of the support structure to which they are attached. Differential thermal expansion and contraction of the rails with respect to the support structure may be accommodated without binding or distortion of the rails by coupling each guideway to the support structure at two different points. Typically, the coupling at the first point is rigid and prevents any movement of the rail with respect to the support structure. The second coupling includes a flexible component that permits movement of the rail with respect to the support structure in a direction of movement of the element or component. This flexible component may be a leaf spring. In another embodiment, the first coupling may also be flexible.Type: GrantFiled: December 6, 2005Date of Patent: March 20, 2007Assignee: Hexagon Metrology ABInventors: Wilhelmus Godefridus Weekers, Jens Hupkau, David W.
