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.
