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.

Appl. No.:

13/567765

Inventors:

Jerry T. Huang - Diamond Bar CA, US

International Classification:

A61C 17/12

US Classification:

433 99, 433216

Abstract:

A dental piezoelectric ultrasonic magnetic switching scaler handpiece is activated by magnetic means. The dental piezoelectric scaler handpiece includes a housing that contains a fixed magnet and a magnetically activated switch. An activation magnet longitudinally slides along the outside of the housing from a de-energized position to an energized position. The activation magnet is biased to the de-energized position by the fixed magnet. When a user moves the activation magnet away from the fixed magnet and toward the magnetically activated switch, the magnetic field of the activation magnet activates the magnetically activated switch and turns the dental scaler handpiece on.

G02C 708

US Classification:

351 47

Abstract:

A lens locator positions a pair of lenses. The lens locator has a plurality of buckles and a connector which is made a of titanium-nickel alloy. The buckle has a hook extending from one end of the buckle and a generally U-shaped groove defined by the buckle. The U-shaped groove receives a lens of the sunglasses while folded and the U-shaped groove receives a lens of regular glasses while the sunglasses are in.

International Classification:

G02C9/00

US Classification:

351 47

Abstract:

A reshapable sunglasses frame having a bridge with two open elliptical lens frames made of soft reshapable metal that will retain the shape that it is bent to and has a gap in each lens frame for inserting the lens. Each gap is closed by a thin string that is pulled tightly around the lens and attached to the two ends of each lens frame. The reshapable sunglasses frame is easily reshapable by bending each of the lens frame to conform to the shape of the lens. Once the lens frames are bent to the new shape, it will retain its new shape until further reshaping.

Abstract:

The present invention is directed to a bite tray having fiducial markers for head scan registration and method of use. The bite tray is held by a patient in his teeth while the scan of his head and the fiducial markers is made by x-ray, CT, or MRI and the scan is entered into a computer to register the scan to the fiducial markers. Instrument optical markers are placed on a dental instrument and it is observed by a camera and the observation is entered into the computer to register the instrument optical markers to the dental instrument. Patient optical markers are placed on the patient and it is observed by the camera and the observation is entered into the computer to register the patient optical markers to the patient. The tip of the dental instrument is then touched to one of the fiducial markers making the location of the tip and the fiducial marker the same. The computer then registers the scan to the instrument and the patient. The bite tray is then removed from the mouth allowing access by the dentist to the teeth. The camera follows the movement of the instrument optical markers to the patient optical markers to create a display of the instrument and tip on the scan.
