Filed:

Jul 19, 2001

Appl. No.:

09/907905

Inventors:

Richard J. Szwec - Roanoke VA
David R. Kegley - Roanoke VA

Assignee:

ITT Manufacturing Enterprises, Inc. - Wilmington DE

International Classification:

G06F 1900

US Classification:

702 78, 327178, 327291

Abstract:

A controllable pulse generator apparatus and method are provided according to the invention. The pulse generator generates an adjustable, high current, high voltage pulse train output that may be transmitted to an external device under operation. The pulse generator includes a controller device and a pulse generator device. The controller device accepts one or more pulse train requests, may accept one or more external signals, and may accept feedback from the device under operation. The controller device generates one or more pulse train signals in response to the pulse train requests, the external signals, and the feedback. The controller device transmits the one or more pulse train signals to the pulse generator device. The pulse generator device receives the one or more pulse train signals and in response generates a pulse train output of a predetermined current level and of a predetermined voltage level according to the one or more pulse train signals.

Richard Szwec - Roanoke VA, US
Edward Donoho - Roanoke VA, US

International Classification:

G01N003/08

US Classification:

073/818000

Abstract:

A method of non-destructively testing the adhesion of electrical leads joined to a package comprising the steps of holding the package and a portion of a lead in respective stationary positions, applying a force to the lead proximate an area where it's joined to the package, and measuring the resistance of the lead to the force. An apparatus for holding the package and leads during such testing comprising first and second holding members, each having three arms connected by a transverse member.

International Classification:

H01P 104

US Classification:

333260

Abstract:

A miniature coaxial connector with a mating end for mating to another connector and a termination end for direct connection to a circuit, provides a closely controlled impedance along its entire length. The connector comprises a coax assembly (14, FIG. 2) having a glass bead (120), a conductive pin (28) projecting through the bead, and a conductive impedance member (40) surrounding the bead. The coax assembly is installed in a connector body (12) having a hollow front mating end portion (50) and a rear end portion (52). The impedance member of the coax assembly has a flange (46) lying on the front face (34) of the bead, and the rear of the body includes a precision passage (60) with the pin projecting completely through the passage and with only air between the pin and passage walls. This arrangement provides precision alignment of the pin with grounded conductive surfaces surrounding it. The flange provides a precision transformer at the front of the pin where it will engage a socket of a mating connector.
