Publication number: 20040124834Abstract: Described are methods for pressurizing elastic support structures or balloons in sensor probes used for the inspection of components having areas of limited access. When inflated, the balloons press flexible sensors against the surface of the material under test. When deflated, the balloons permit easier insertion of the probes into the component and reduce the mechanical stresses on the sensors, thereby extending the sensor lifetime. By sequentially partially inserting the sensor into a limited access area from either side of the limited access area and scanning in opposite directions, the entire surface of the test material can be inspected.Type: ApplicationFiled: August 28, 2003Publication date: July 1, 2004Applicant: JENTEK Sensors, Inc.Inventors: Neil J.

The gauge bracket (16) includes ratcheting surfaces (22) for retaining the housing (14) to the bracket (16) in any one of various positions. The ratcheting surfaces (22) are disposed upon flexible tabs (24) extending from the bracket (16). The gauge housing (14) includes a plurality of annular and parallel ribs (26) for engaging the ratcheting surfaces (22) on the tabs (24).Type: GrantFiled: June 16, 1999Date of Patent: June 12, 2001Assignee: Teleflex, IncorporatedInventors: Steve D. Nelson, Richard K. Anderson, Jack T. Sossamon

Patent number: 6192755Abstract: A dial gauge case, which has a bottom and a peripheral wall surrounding the bottom, the bottom and the peripheral wall defining a recess for accommodating a dial gauge mechanism therein. The peripheral wall is provided with a pair of bearings for slidably supporting a spindle of the dial gauge. The peripheral wall and the pair bearings are formed together as a one-piece molding of a plastic material. With the peripheral wall and the bearings formed together as a one-piece molding, the number of dial gauge components can be reduced, and the operation of assembling the dial gauge is simplified.Type: GrantFiled: September 22, 1997Date of Patent: February 27, 2001Assignee: Mitutoyo CorporationInventors: Munenori Ishii, Toshiyuki Shinohara

Patent number: 6170329Abstract: An improvement in the enclosure assembly for automated testing devices. The enclosure includes various modular components, such that one components contains common elements and another component contains unique elements. The common elements may be elements found in a design family and the unique elements may be the unique feature of a device in a design family. The customized and common components are mounted in a chassis and enclosed with a cover.Type: GrantFiled: June 14, 1999Date of Patent: January 9, 2001Assignee: Agilent Technologies, Inc.Inventor: Edward Steketee

Patent number: 6112593Abstract: A non-destructive inspection device has an inspection unit body and a support casing which is used as a set-up type device by combining the inspection unit body and the support casing in ordinary inspection, and is used as a portable type device by separating them for special inspection situations involving narrow places or high places. The support casing can be freely combined to or separated from the inspection unit body. When combining the two components, the non-destructive inspection device can carry out the inspection based on a stable set-up mode in the same way as conventional devices. When separated, the inspection unit body is used as a portable device.Type: GrantFiled: November 10, 1998Date of Patent: September 5, 2000Assignee: Hitachi Construction Machinery Co., Ltd.Inventors: Shigenori Aoki, Tohru Miyata, Seigo Kikuchi, Shigeru Miwa, Hajime Mizunoya, Takenori Hiroki

Patent number: 6115261Abstract: A sensor mount for mounting a sensor to a substrate having a support member, a substrate attachment surface, and a sensor attachment surface. The support member can be attached to the substrate at the substrate attachment surface and the sensor can be attached to the support member at the sensor attachment surface. The sensor mount is shaped so an oblique angle is formed between the plane that includes the substrate attachment surface and the plane that includes the sensor attachment surfaces. Preferably, the support member has a wedge shape.Type: GrantFiled: June 14, 1999Date of Patent: September 5, 2000Assignee: Honeywell Inc.Inventors: William P. Platt, Dale J. Hagenson, Douglas P. Mortenson
