Title: Field electron emission materials and devices
Inventor: TUCK RICHARD ALLAN
IPC: H01J9/02
Filed: 1999-07-30
Abstract: A field electron emission material has a substrate (1700) with an electrical ly conductive surface. Electron emission sites on the conductive surface each include a layer of electrically insulating material (1703) to define a prima ry interface region (1702) between the conductive surface and the insulating layer (1703), and a secondary interface region between the insulating layer (1703) and the vacuum environment. Each primary interface region (1702) is treated or created so as to enhance the probability of electron injection fr om the conductive surface into the insulating layer (1703). Each primary interface region (1702) after such treatment or creation is either an insulator or graded from conducting adjacent the conductive surface to insulating adjacent the insulating layer (1703).

Title: Method for determining warp potential in wood
Inventor: STANISH MARK A
IPC: G06F9/46
Filed: 1999-09-01
Abstract: A method for determining warp potential of wood. One embodiment comprises nondestructively obtaining lengthwise shrinkage rates and grain angles of wood - such as trees, logs, or lumber - then determining warp potential of the wood based on the lengthwise shrinkage rates and grain angles. The method typically comprises measuring plural lengthwise shrinkage rates and plural grain angles to determine wasp potential. Where the wood comprises lumber, lengthwise shrinkage rate and grain angle measurements typically are made on at least one major planar surface of the lumber at at least two measuring points separated by a predetermined distance, such as at substantially one-foot intervals along the lumber. Particular embodiments of the present invention determine lengthwise shrinkage rates using electromagnetic energy, acoustic energy, and combinations thereof.  Working embodiments of the method use ultrasound energy to determine lengthwise shrinkage rates and grain angles. Another embodiment of the present invention comprises providing a piece of wood having at least one major planar surface, positioning the piece of wood adjacent to a device for imparting energy through the piece of wood to determine at least one lengthwise shrinkage rate and at least one grain angle. Embodiments of the present invention are automated and can be adapted to industrial processes for commercial production of lumber or for forest management practices. Warp potential can be determined using a finite element model (FEM).
