Filed:

Nov 20, 2001

Appl. No.:

09/989626

Inventors:

Sanjiv Singh Samant - Cordova TN
Jinesh Jitendra Jain - Memphis TN
Joseph Laughter - Millington TN

Assignee:

St. Jude Childrens Research Hospital - Memphis TN
The University of Tennessee Research Corp. - Knoxville TN

International Classification:

H05K 100

US Classification:

361749, 361750, 361751, 361790, 439 67, 174250, 174254

Abstract:

An easier and cheaper way to obtain multilayer circuit board is by using a flexible circuit board and folding it in an organized pattern. Flexible circuit has the unique property of being a three-dimensional circuit that can be shaped in multiplanar configurations, rigidized in specific areas, and molded to backer boards for specific applications. The folded circuit is fabricated from a series of foldable circuit board strips and rigid circuit board strips which are interconnected, folded, and bonded into a composite structure. The foldable strips may have prefolds arranged so that a group of upper foldable strips and lower foldable strips are folded in opposite directions. A plurality of intermediate portions are stacked on each other by the folding the foldable strips in opposite directions. The folded circuit, can be bonded after a first fold, or folded further to achieve a greater reduction in area and subsequently be bonded as a composite multilayer structure.

International Classification:

B64D 4702

US Classification:

244 75R

Abstract:

An apparatus for use in an ultralight aircraft, glider, or sailplane to detect and navigate within thermal updrafts is disclosed. The apparatus includes a right temperature sensor and a left temperature sensor mounted on the wings of the aircraft. A difference circuit and difference indicator measure and indicate whether the right or left sensor is warmer and indicate a measured temperature difference. A derivative circuit and derivative indicator measure and indicate whether the air temperature is increasing or decreasing and indicate a rate of temperature change. The derivative circuit may be responsive to any of the right temperature sensor, the left temperature sensor, both the right and left temperature sensors, or to a third temperature sensor mounted on the aircraft. The apparatus detects thermal updrafts and indicates to the pilot when and how rapidly to turn to obtain the maximum lift from the thermal updraft.
