Filed:

Jul 17, 1997

Appl. No.:

8/896213

Inventors:

David A. Crenshaw - Roanoke VA
Mark R. Critzer - Salem VA
John T. Domalski - Roanoke VA

Assignee:

ITT Manufacturing Enterprises, Inc. - Wilmington DE

International Classification:

H01M 1046

US Classification:

320114

Abstract:

A clip-on power source for powering an ANVIS binocular. The power source has an electrical interface that enables the power source to be detachably coupled to the ANVIS binocular. The interface also enables the power source to pivot relative to the binocular from a first position to a second position to power-on and power-off the ANVIS binocular.

International Classification:

A42B 322
F41H 104

US Classification:

244121

Abstract:

A quick release coupling apparatus and method used to connect and quickly disengage a night vision assembly from a pilot's helmet. The quick release coupling apparatus includes a locking element disposed on a pilot's helmet. An aperture is disposed on the night vision assembly to be attached to the pilot's helmet. The locking element of the pilot's helmet is passed into the aperture of the night vision assembly wherein the locking element is engaged and retained by a collet. The collet is biased against the locking element by a wire that is wrapped around the collet. As such, the collet engages the locking element and prevents the locking element from being withdrawn out of the night vision assembly, thereby firmly joining the night vision assembly to the pilot's helmet. Springs or similar repelling elements are disposed between the night vision assembly and the pilot's helmet. The springs act to bias the night vision assembly and pilot's helmet away from each other but the bias is checked by the presence of the locking element in the collet.

Assignee:

ITT Corporation - New York NY

International Classification:

H05K 900
H01Q 1700

US Classification:

320 13

Abstract:

An improved battery pack for night vision goggles is employed in the cockpit of an aircraft, where RF fields of several hundred volts/meter are present. The improved battery pack includes a shunt circuit for shunting RF signals picked up by any external leads from the battery pack, and a resistor for dissipating electromagnetic energy from the RF signals shunted by the shunt circuit.
