US Patent:

6575036, Jun 10, 2003

Filed:

Jun 22, 2000

Appl. No.:

09/602173

Inventors:

Jerry Qixin Huang - Hacienda Heights CA
Robert J. Perez - Westminster CA
Leo M. DeLangis - Lomita CA

Assignee:

The Boeing Company - Seattle WA

International Classification:

G01N 2918

US Classification:

73597, 73602, 73644

Abstract:

A method for determining stiffness of a composite laminate plate entails disposing a device for generating an acoustical pulse against a surface of the plate and disposing a detecting device against the same surface spaced a known distance from the pulse-generating device, and using the pulse-generating device to emit a pulse so as to create an extensional wave in the plate. The detecting device is used to determine a time of flight of the wave over the known distance, and the wave velocity is calculated. A Youngs modulus of the plate is determined based on the wave velocity. Methods for both anisotropic and quasi-isotropic laminates are disclosed.

US Classification:

73597, 73602, 73644

Abstract:

A method and apparatus for determining stiffness of a plate-like structure including a monolithic or composite laminate plate entails disposing a device for generating an acoustical pulse against a surface of the plate and disposing a detecting device against the same surface spaced a known distance from the pulse-generating device, and using the pulse-generating device to emit a pulse so as to create an extensional wave in the plate. The detecting device is used to determine a time of flight of the wave over the known distance, and the wave velocity is calculated. A Young's modulus of the plate is determined by a processor based on the wave velocity. Methods and apparatus for evaluating both isotropic plates and anisotropic laminates are disclosed.

US Classification:

705037000

Abstract:

A trading appliance for an electronic trading system comprises a keypad into which is integrated a computer which communicates between the keypad and the trading system. The keypad has keys for entry of trade related data into the trading system. A retractable keyboard has keys for entry of non-trade related data into the trading system and may be retracted to a position within the keypad housing. A mouse is provided on the keypad. A display monitor may be connected the keypad for display of trading data received from the keypad and the trading system. A portion of the keypad, and an associated circuit boards may be detached and replaced by a keypad portion appropriate for trading a different instrument or on a different market.
