Optical Fiber Attenuator
US Patent:
6456775, Sep 24, 2002
Filed:
Apr 5, 2001
Appl. No.:
09/826523
Inventors:
Warren Johnson - Wilmington DE
N. John Nagurny - Haddonfield NJ
N. John Nagurny - Haddonfield NJ
Assignee:
General Instrument Corporation - Horsham PA
International Classification:
G02B 636
US Classification:
385140, 385 15, 385 39
Abstract:
An optical fiber attenuator for adjusting the attenuation of a fiber optic cable, including a generally L-shaped housing with a spring clip positioned within the housing. The spring clip is adjustably positioned to change and hold the radius of curvature of a fiber optic cable wrapped around the spring clip. The fiber optic attenuator is fitted with a movable arm mounted to its housing which engages and adjusts the spring clip through a plurality of positions to adjust the position of the spring clip, thereby adjusting the attenuation of the fiber optic cable.
Photodiode/Laser Mounting Bracket
US Patent:
6639809, Oct 28, 2003
Filed:
Oct 26, 2000
Appl. No.:
09/697619
Inventors:
Brett Rosen - Richboro PA
Warren Panama Johnson - Wilmington DE
Warren Panama Johnson - Wilmington DE
Assignee:
General Instrument Corporation - Horsham PA
International Classification:
H02B 101
US Classification:
361825, 361807
Abstract:
An apparatus and method for mounting an electronic component device directly to a plug in board within an electronic product thereby eliminating differential movement between the mounting surface of a mounting bracket holding an electrical component device, and the plug in board to which the component device is attached during transportation or use. By eliminating differential/relative movement between the anchoring surface of the mounting bracket and the plug in board commonly found in conventional applications, the stresses generated by differential movement of the connection leads of the mounted component device, relative to the plug in board, and the concomitant potential for degradation of component device performance resulting therefrom, are eliminated.
