Abstract: The present invention relates to firearms recoil reducer. Current reducers are some type of shock absorbers with limited efficiency, of about 15%. The lift and the back kick of the firearm remain causing pain to the shoulder and instability in targeting especially with repeating firearms. In my invention the combined recoil of primary recoil associated with bullet speed and about four folds more powerful secondary recoil associated with exploding gas burst leaving the front of the barrel are countered by the backwards puff of the burst by the recoil reducer. The secondary recoil resulting from exploding gas burst leaving the barrel is utilized to nullify the primary and part of the secondary recoil. My recoil reducer is a wide cap absorbing the explosion and pulling forward the muzzle to counter the native recoil. The recoil reduction is further maximized or reinforced by a duckbill valve, by wide flat cap, by flat cap with side walls or rims, and by a cup shaped reducer with a hole in its bottom part.

Abstract: The present invention relates to artillery shell range, cannon fired satellite, missiles, and communication satellite launcher. Cannon shell range can be increased by decreasing the drag through making the flat base shape into inverted cone or by fastening a wood or lightweight plastic cone. Fastening a booster filled with gun powder to the base of the shell with a delay primer fuse that explodes in flight get the recoil push the trajectory higher in the air and faster in speed to reach a longer range. Adding multiple boosters in tandem causes successive explosions in flight that the successive recoils speeds up the shell in-flight and increases the range. Fastening a round thin steel smooth barrel to the base of the shell and stacking multiple flat sides or cone shaped boosters separated by felt or plastic separators with center holes filled with slow burning primer adds more blank-type recoil to enchance shell speed and range.

Abstract: A relatively low cost but effective vehicular safety system includes a navigational status determination system generating navigational status information, an alarm response system generating alarm responses in response to alarm response command information and a data processing system. The data processing system stores a list of safety zones having one or more safety conditions for each safety zone. The data processing system receives the navigational status information and compares the received navigational status information to the stored safety conditions. If a safety condition is found to be violated the data processing system communicates a response command to the alarm response system. Depending upon the severity of the violated safety condition, the alarm response system notifies the vehicle operator of the violation, notifies law enforcement authorities external to the vehicle of the violation or takes some other safety response.

Abstract: The present invention relates to flying airplane security during landing or taking off from the risk of surface to air missiles fired by shoulder held launchers as the heat seeking Stinger or SAM-18 missile. In Kenya two stinger missiles attempted to down an Arkia Israeli airliner carrying tourists. Stinger or SAM-18 surface to air missile available on black market and fired from shoulder-held launcher with heat seeking guidance head might be deadly to low flying passengers planes worldwide, the USA included. This missile deflector system positioned at the rear belly of the plane comprises a missile detector and a decoy IR light source sprung to trail the plane. The detector can be an infrared-daylight video camera with a fisheye lens, a flying laser spot, a flying line laser, a range finder, and with software for motion detection.

Abstract: The present invention relates to preventing one or a group of suicide hijackers from taking over control of an airplane and crashing it onto public facility such as a building, city, dam, atomic reactor, or ship for the purpose of causing mass destruction and killing of innocent civilians. This invention comprises multiple defense stations inside the passengers cabin. Each station has a motorized defense tool, video camera viewer with remote controller is in front of the pilot and in airline, FBI, and CIA headquarters. Each station has one of the following; a defense tool, a gun with silencer, stunt gun, tranquilizer, MACE or pepper sprayer, arrow thrower with high voltage electric charge, wood hammer, head banger, stomach puncher, foot tripper and trap, head holder, waist grabber, or a leg trapper or breaker as one of the stunt none-lethal and no permanent damage to immobilize the intruders.

Abstract: An arrangement for using laser light in densitometers and spectrophotometers by using filters to cut down intensity and variable slits to regulate sensitivity. The arrangement also contemplates stretching the spot laser to a line laser by using a hollow transparent tubing in front of the laser and moving it to obtain various intensities. The line laser may be focused by a cylindrical lens at a fixed position, and the beam width may be adjusted by moving a cylindrical lens away or closer to the sample object. Furthermore, a slit before the sample and a slit after the sample will improve resolution by cutting off diffracted or aberated light.

Abstract: An arrangement for producing a laser beam as a line utilizing a sharp straight edge intercepting a portion of the original spot laser beam. The use of an diffraction grating at varying angles of the incident spot laser beam also produces a stretched laser spot of various orders with laser lines connecting the various orders.
