US Patent:

51111420, May 5, 1992

Filed:

Aug 8, 1990

Appl. No.:

7/564272

Inventors:

Daniel P. Mazzone - Dayton OH
James D. Hoeffel - Centerville OH
James S. Nevitt - Bellbrook OH
Richard E. Elliott - Dayton OH

Assignee:

Systems Research Laboratories, Inc. - Dayton OH

International Classification:

G01N 2772
G01R 3312

US Classification:

324262

Abstract:

A detachable, articulated rotating eddy current inspection tool includes a body member having a connector at one end for mechanically and electrically attaching the body member to a rotating drive member while at the other an eddy current probe is supported for radial movement with respect to the axis of rotation of the body member. A motor located within the body moves a slide on which the probe is mounted while at the same time a counterbalancing slide is moved radially in the opposite direction to maintain said tool in dynamic balance. An encoder housed within said body member senses the location of said eddy current probe with respect to the axis of rotation of said body member. A rotary transformer is used to transfer signals which control the position of the probe and to receive information from the eddy current probe and the encoder. The encoder output signals are modulated by the eddy current probe exciter signal to enable probe positions information to be sent through a rotary transformer.

International Classification:

G01B 1304

US Classification:

73 375

Abstract:

An apparatus for maintaining the end of a probe carrying a sensor, such as an eddy current probe, a predetermined distance from a workpiece includes a housing in which a piston is permitted to move. Air under pressure, introduced into a first chamber formed within the housing, acts on a first surface of the piston to urge it toward the workpiece. An air bearing is used to permit the almost friction free axial movement of the piston within the housing. Some of the air passes from the first chamber through a restricted opening in the piston into a second chamber and is vented toward the workpiece. The pressure in the second chamber will vary as a function of the distance of the end of the probe to the workpiece surface. The piston is provided with a second, larger, surface area exposed to the variable pressure in the second chamber, and as a result, the piston is urged away from the workpiece. The pressures acting in the two surfaces work together to maintain the piston, and the sensor, a constant distance from the workpiece.

Abstract:

Technology for detecting and remediating security vulnerabilities in view of one or more computing policies. An example method may involve receiving environment data of a computing environment, the environment data comprising a configuration value of a computing device in the computing environment; accessing an index data structure derived from a computing policy, wherein the index data structure associates an entry of the computing policy with one or more computing features of the computing environment; determining, by a processing device, whether a security vulnerability exists based on the environment data and the index data structure; and providing feedback regarding the security vulnerability and the computing policy.
