US Patent:

D472197, Mar 25, 2003

Filed:

Dec 3, 2001

Appl. No.:

29/151359

Inventors:

Lee K. Clark - Santa Ana CA 92705

International Classification:

1216

US Classification:

D12213

US Patent:

H2470, Apr 7, 1987

Filed:

Jul 11, 1986

Appl. No.:

6/887496

Inventors:

Lee K. Clark - Santa Ana CA
Michael C. Peron - Eltoro CA
James A. Wes - Diamond Bar CA

Assignee:

The United States of America as represented by the Secretary of the Army - Washington DC

International Classification:

G06F 1550
G05D 108
G01C 2300

US Classification:

364434

Abstract:

A roll measurement system for a flight vehicle, such as a tank-launched ged projectile or guided missile, includes a power source and a pulsed laser, such as a laser diode, which propagates a laser beam which is focused into a narrow conical beam and directed toward the earth. The laser beam's reflections from the earth are detected, for example, by a photo-diode, and converted into an analog electrical signal. The signal is converted to digital form and analyzed to determine its nadir (the shortest path-length to the earth). A microcomputer compares the immediate nadir determination with stored nadir determinations to compute the angle and rate of roll of the flight vehicle.

US Patent:

43542786, Oct 12, 1982

Filed:

Dec 10, 1980

Appl. No.:

6/214970

Inventors:

Lee K. Clark - Santa Ana CA
Michael C. Peron - Diamond Bar CA

Assignee:

Northrop Corporation - Hawthorne CA

International Classification:

H04B 900

US Classification:

455617

Abstract:

A projectile carries a laser transmitter which directs its output beam to the rear through an aperture in the projectile. The beam is coded (modulated) in accordance with the start or stop of events or flight conditions being monitored by one or more transducers in the projectile. The beam is initially pulsed at a known reference rate from a thermal battery automatically activated by the launching acceleration of the projectile. Thus, occurrence of an event or condition will change the laser frequency to a new predetermined rate. The beam can be decoded at a receiving station in the vicinity of the launching site.

H377, Jul 7, 1987

Filed:

Jun 23, 1986

Appl. No.:

6/877945

Inventors:

Stefan T. Epure - late of San Marino CA
Lee K. Clark - Santa Ana CA
James P. Haine - Tustin CA

Assignee:

The United States of America as represented by the Secretary of the Army - Washington DC

International Classification:

H05K 506
B29C 4318
H05K 114

US Classification:

174 52PE

Abstract:

The invention concerns a technique and apparatus for protecting sensitive ectronic components against the high accelerations encountered in a tank-powered projectile, for instance. A first ring is placed on a circuit board and filled with an RTV compound. A cap is placed on the first ring to force excess RTV compound from the first ring, and is removed once the RTV compound cures. A second shorter ring is placed about the RTV compound and is attached to the circuit board. A flat plate is then used to press the RTV compound into any voids which may exist between elements mounted on the circuit board. Circuit modules created in this manner may be stacked upon one another and interconnected.
