Filed:

Apr 26, 2001

Appl. No.:

09/842539

Inventors:

James F. Freeman - Memphis TN
Roy E. Williams - Collierville TN

Assignee:

Memphis Eye Contact Associates - Memphis TN

International Classification:

G06K 900

US Classification:

382128, 348 78

Abstract:

An automated eye corneal striae detection system for use with a refractive laser system includes a cornea illuminator, a video camera interface, a computer, and a video display for showing possible eye corneal striae to the surgeon. The computer includes an interface to control the corneal illuminator, a video frame grabber which extracts images of the eye cornea from the video camera, and is programmed to detect and recognize eye corneal striae. The striae detection algorithm finds possible cornea striae, determines their location, or position, on the cornea and analyzes their shape. After all possible eye corneal striae are detected and analyzed, they are displayed for the surgeon on an external video display. The surgeon can then make a determination as to whether the corneal LASIK flap should be refloated, adjusted or smoothed again.

International Classification:

E21B 47/12

US Classification:

1662542, 166 651, 166 66, 7315203, 7315231

Abstract:

In at least some embodiments, a tool may comprise a tool body and one or more tool components. The tool may further comprise tool electronics located within the tool body, wherein the tool electronics are operable to sense and store tool component characteristics and environmental characteristics. At least some of the tool electronics are operable, at least for one week, when exposed to temperatures of at least 200 Celsius. The tool electronics may be integrated circuits formed on a silicon carbide substrate or a silicon on sapphire substrate. One illustrative embodiment of the tool is a drill bit for employment in a high temperature drill well.

International Classification:

G01V 3/30

US Classification:

324338, 324339

Abstract:

A resistivity tool includes receiver electronics near each receiver antenna loop. Placement of the electronics in this position such as at the circuit card between the terminal ends of the receiver antenna loop improves signal to noise ratio by reducing or eliminating interference, noise, and cross-talk of transmissions from the receiver to a remote microprocessor. By using material such as silicon-on-sapphire, electronics can be miniaturized and operate reliably at when exposed to high temperatures, even for long periods.

International Classification:

G01J 5/00

US Classification:

2503381, 25033802

Abstract:

High temperature imaging devices are disclosed. In one embodiment, the imaging device comprises an array of photosensitive elements fabricated on an insulator substrate, and an information storage component coupled to the array. The information storage component stores data representing one or more light patterns detected by the array. The light patterns may be images or spectral patterns. The insulator substrate may be a sapphire or spinel substrate. Alternatively, the substrate may be silicon carbide or an insulated silicon substrate. In at least some embodiments, a processor is integrated on the same substrate as the array.
