IPC: G01N25/72
Filed: 2000-07-10
Granted: 2001-11-11
Abstract: In an infrared (IR) transient thermography system a sequence of image frames is acquired from an IR sensitive focal-plan array camera. Each sequentially acquired image frame is made up of an array of pixels and has assigned a frame-number that corresponds to elapsed time. Temperature-verses-time (T-t) data corresponding to each pixel is developed from stacks of sequential image-frames. A method of analyzing the stacks of thermal data image-frames is presented wherein either the Real or the Imaginary component portions of a Fast-Fourier Transform of a normalized T-t data curve from each pixel is used to determine the thickness of an object and produce a color-keyed or gray-scale coded thickness map.

Title: A display computer with on-screen identifiers for multiple serial ports for avoiding physical mislabelling of ports
Inventor: HAMILTON II RICK ALLEN
IPC: G06F13/38
Filed: 2000-07-26
Granted: 2004-01-01
Abstract: In a display computer with multiple serial ports, there is provided an on-screen facility for identifying each of the serial ports with a numerical identifier. A process is provided responsive to a change in the status of a connection to any serial port that displays the identifier for that serial port. The change in status takes place when connecting to the serial port. The process may be effectively used in systems having their serial ports extended through a universal serial bus. The identifiers for the serial ports may be stored in a look-up table from which the appropriate identifier may be obtained and displayed upon the connection of a peripheral device to a serial port. Among the many advantages of this on-screen serial port identification is the assurance that the user will not be confused or obstructed by any errors in the physical labelling of serial ports in the manufacture or assembly of computer hardware. Such mislabelling is often the result of unintentional cross-overs in the wiring of the multiple serial ports.

Abstract: An aberration correction element having first and second retardation members whose refractive indices are different for a predetermined polarized light beam, so that the first and second retardation members causes a phase difference of an incoming light beam according to the polarization of the incoming light beam, and an optical pickup adopting the aberration correction element are provided. When the aberration element is designed such that a phase difference caused by the aberration correction element with respect to a wavelength variation of incoming light beam increases of decreases with increasing distance from the optical axis, and then adopted in an optical pickup for high-density recording and reproduction with a shorter wavelength light beam, chromatic aberration caused by a slight wavelength variation between record and reproduction modes can be corrected with high light efficiency. The aberration correction element selectively causes a phase difference of incoming light beam according to the polarization of the incoming light beam, and thus it can be adopted in an optical pickup compatible for high-density and low-density recording media using two polarized light beams perpendicular to each other.
