6466310, Oct 15, 2002

Filed:

Aug 20, 1998

Appl. No.:

09/077499

Inventors:

Sang Van Nguyen - Huntington Beach CA
Foad Towfig - Oceanside CA
John Andrew White - Orange CA

Assignee:

McDonnell Douglas Corporation - St. Louis MO

International Classification:

G01N 2100

US Classification:

356 731

Abstract:

A method and apparatus are provided for inspecting an end face of an optical fiber. The apparatus includes a memory device for storing images of acceptable end faces and unacceptable end faces, and an imaging system for obtaining an image of the end face of the optical fiber. Further, the apparatus includes a means, responsive to said imaging system, for comparing the image of the end fare of the optical fiber with the images of acceptable end faces and unacceptable end faces to automatically determine if the optical fiber is acceptable.

McDonnell Douglas Corporation - St. Louis MO

International Classification:

B65H 6704

US Classification:

2424766, 242439, 29710

Abstract:

A method and apparatus is provided for mounting any one of a plurality of types of connectors upon the end portion of a fiber optic cable. The automated fiber optic connectorization apparatus includes a memory device for storing data relating to a plurality of types of connectors. The automated fiber optic connectorization apparatus also includes a controller for receiving input from a system operator or other source that specifies the type of connector to be mounted upon the specified fiber optic cable, the polishing geometry, and the optical performance specifications. Based upon this input, the controller determines the components required to mount the specified type of connector upon the end portion of the fiber optic cable based upon the data stored by the memory device. The automated fiber optic connectorization apparatus also includes means for obtaining the necessary components and means for assembling these components upon the end portion of the fiber optic cable. Therefore, the automated fiber optic connectorization apparatus can automatically mount the specified type of connector upon the end portion of the fiber optic cable.

International Classification:

G01N 2100

US Classification:

356 731

Abstract:

A cassette for preparing an end face of an optical fiber includes a housing that defines a window, and a supply reel and a take up reel disposed within the housing. The cassette also has a preparatory tape, advancing between the supply reel and the take us reel, for preparing the end face of the optical fiber. In addition, the cassette includes means for directing the tape by the window defined by the housing such that the tape contacts and prepares the end face of the optical fiber.

US Classification:

307 38, 307 65, 363 71

Abstract:

Presented is a system and method for providing reconfigurable AC interfaces for AC power systems. The method comprises embedding a reconfigurable AC interface for transferring power between power sources and loads, monitoring the voltage and current of the interfaces of the reconfigurable AC interface, and switching between power sources based on the monitoring. The system comprises a reconfigurable AC interface further comprising an inverter for converting DC power to AC, transfer switches with interfaces for connecting to the inverter, other transfer switches, and AC busses, and a controller that dynamically configures the transfer switches to transfer power between the inverter, and AC busses.
