Title: Transient thermography measurement of a metal layer thickness
IPC: G01N25/72
Filed: 2000-04-13
Abstract: An IR transient thermography imaging system includes high-power flash lamps fitted with spectrally tuned optical filters and a focal-plane array camera for IR image data acquisition. The image data processing control computer analyzes acquired IR image data frames and provides a color-keyed display of an imaged object that correlates to object thickness over the imaged surface area. Acquisition of IR data is initiated at a firing of flash lamps used to heat a surface of the object along with a reference standard. A predetermined number of IR image frames are acquired and recorded over a predetermined period of time after firing of the lamps to develop a temperature-time (T-t) history of the object surface and the reference standard. A contrast curve is calculated for each pixel in the image frame, each pixel corresponding to an elemental region on the object surface. Gaussian temporal smoothing of contrast curve data is performed to improve signal-to-noise characteristics and a derivative of the contrast curve is determined using data points mathematically related to image frame number. All local peaks in the derivative of the contrast curve are identified and given significance according to a predetermined weighting function. The frame number of the most significant peak is used to determine time of occurrence of an "inflection point" in the contrast curve which is then used in determining object thickness. Gain correction of pixel intensity data is employed to offset IR emissivity variations caused by surface curvatures and varying surface conditions on an object.

Title: Dynamic connection to multiple origin servers in a transcoding proxy
IPC: H04L29/08
Filed: 2000-06-28
Abstract: A method of enabling a proxy to participate in a secure communication between a client and a set of servers. The method begins by establishing a first secure session between the client and the proxy. Upon verifying the first secure session, the method continues by establishing a second secure session between the client and the proxy. In the second secure session, the client requests the proxy to act as a conduit to a first server. Thereafter, the client and the first server negotiate a first session master secret. Using the first secure session, this first session master secret is then provided by the client to the proxy to enable the proxy to participate in secure communications between the client and the first server. After receiving the first session master secret, the proxy generates cryptographic information that enables it to provide a given service (e.g., transcoding) on the client's behalf and without the first server's knowledge or participation. If data from a second server is required during the processing of a given client request to the first server, the proxy issues a request to the client to tunnel back through the proxy to the second server using the same protocol.
