US Patent:

20080183207, Jul 31, 2008

Filed:

Jan 25, 2007

Appl. No.:

11/657790

Inventors:

John N. Horne - Los Alamos NM, US

International Classification:

A61B 17/00

US Classification:

606203

Abstract:

A tourniquet having a strap and a pressure applying cam. The cam functions as both a buckle, to allow the strap to be tightened about an injured limb, and also as a pressure applicator that can be selectively positioned and applied to a specific arterial pressure point of the limb. The cam is shaped to have an upwardly extending portion which, when reversed in orientation, extends radially inward toward a limb and can be applied to an arterial pressure point to further control bleeding. In operation, the strap is pre-threaded through the cam for storage and preparation for use. In an emergency the tourniquet is first loosely applied to the injured limb and the strap then tightened and secured to the cam to constrict the limb. The strap is then pulled up and over the cam to rotate it approximately 180 degrees so that the cam is urged against the desired pressure point, while also further shortening the overall length of the tourniquet and thereby further increasing the tension of the tourniquet. The strap is then fastened to itself to secure the tourniquet in place until medical assistance is available.

Appl. No.:

13/199263

Inventors:

John Horne - Los Alamos NM, US

International Classification:

F41C 27/00

US Classification:

42 90

Abstract:

A multi-purpose firearm servicing tool has an elongated tool body having a first end portion and a second end portion. A bit engaging socket is provided at the first end portion of the elongated tool body. A plurality of deposit scraping structures are positioned around a longitudinal centerline axis of the tool body at the second end portion thereof. A gas tube clamp is provided at a position between the first and second end portions of the elongated tool body. Opposing tube clamp surfaces of the gas tube clamp are selectively movable between a tube clamping configuration and a tube receiving configuration.

Appl. No.:

7/664027

Inventors:

John N. Horne - Los Alamos NM
Michael A. Wolf - Los Alamos NM

International Classification:

F41A 962

US Classification:

42 102

Abstract:

A cartridge monitoring and display system for an automatic or semiautomatic firearm. A programmed microcontroller receives input signals from each of a slide switch and a magazine switch, which switches generate respective signals upon actuation of the firearm slide and upon insertion or withdrawal of a cartridge magazine. The microcontroller calculates the number of rounds remaining in the firearm and displays the number on an LCD display. A visible and audible warning is given when the cartridge count drops below a predetermined minimum level. The entire system is incorporated in a mounting strap which may be inserted between the frame and hand grip of a conventional semiautomatic pistol.
