Assignee:

International Business Machines Corporation - Armonk NY
International Classification:

H04B 1008
US Classification:

359189
Abstract:

An automated, computer-controlled system automatically measures various parameters associated with the transmitter and/or receiver of an electro-optic module. Measured transmitter parameters include transmitter average power, transmitter rise/fall time, transmitter extinction ratio, transmitter duty cycle distortion, and transmitter data dependent jitter. Measured receiver parameters include receiver sensitivity, receiver pulse width distortion, receiver signal detect threshold, and receiver signal detect assert/deassert times.

US Patent:

58778829, Mar 2, 1999
Filed:

Jun 13, 1996
Appl. No.:

8/663339
Inventors:

William F. Green - Vestal NY
Vincent M. Lisica - Raleigh NC
Donald L. Pearl - Endwell NY
Assignee:

International Business Machines Corp. - Armonk NY
International Classification:

H04B 1010
H04B 1024
US Classification:

359163
Abstract:

An optical connection means is provided for connecting an optical docking station to an information handling system and to one or more peripheral devices. The optical connection means comprises two components that are not mechanically attached. The two components are a laptop component that is housed within the information handling system and within the one or more peripheral devices, and a docking station component housed within the optical docking station. The components send and receive information optically (i. e. , in the form of light) to each other.

US Patent:

59108789, Jun 8, 1999
Filed:

Jun 26, 1997
Appl. No.:

8/883488
Inventors:

Alfred A. Mello - Endicott NY
Donald L. Pearl - Endicott NY
Assignee:

International Business Machines Corporation - Armonk NY
International Classification:

H05F 100
US Classification:

361212
Abstract:

Electrical devices such as leaded electronic components, i. e. , components with extended input/output leads, are loaded in a magazine that protects them from electrostatic discharge. Each component is held in a component holder with a conductive shorting or discharge pad, comprising a bundle of conductive filaments within a conductive foraminous web that can be moved into contact with the leads to protect them from electrostatic discharge, and moved away from the leads to allow access for testing or processing. At a testing or processing station, the magazine is placed on a mating base and the devices are supported and positioned by supports on the magazine and base. Upon completion of a testing or processing sequence, the magazine can be separated from the base and moved to another testing or processing station, where the magazine is placed on another base.
