This weapon is a double barrel (slide pump) action shotgun that has the capability of holding fifty (50) rounds of 12 gauge shotgun shells in a side-by-side stagger single box magazine.

The primary feeding mechanisms in use today by shotguns are:
1. Under barrel tube or multiple tubes with a maximum capacity of 16 rounds. 2. Single stack magazines, no more than 10 rounds. 3. Drum magazines with capacities up to 32 rounds but the drums are large, clumsy, fragile and expensive to manufacture. The "stagger" magazine has never been used in a shotgun because, when the stagger magazine is successfully used in rifles and pistols, the bullets have a pointed or round point created ...

In modern wideband receivers one of basic element is ADC,working in undersampling mode or direct RF digitizing

Main imperfections these of modes:

1.Result undersampling is appearance a few digital images of signal,what require application complex filters.
2.Direct digitizing RF/IF require clock generators with minimum jitter and application DDC.
3.Wideband in these receivers limited exemplarily 10-20%RF.

For removal these imperfections i designed ADCs with function RF detector(Fig.2)

So as, parameters vector in constellation (magnitude,phase) define I/Q signals,i suppose digitize amplitudes in I/Q canals will be enough for further processing.

Advantages direct conversion receivers,where used ADCs with function RF detector:

1.In result we have only one digital image of signal.

2.ADCs with function RF detector not require clock generator with minimum ...

Remote manipulation in uncontrolled environments remains challenging despite advances in computing, robotics, and telecommunication. Complex objects can be manipulated with custom fixturing, but this limits adaptability in dynamic environments. Due to their ability to grip and manipulate objects with myriad shapes and textures, humans are still required to manufacture complex devices and structures in extreme environments (i.e. underwater, space, war-zones, etc). This ability is dependent not only on the orientation of the digital manipulators, but also on the ability to dynamically control the force applied to the manipulated object.

Fingers allow a variety of objects to be manipulated without damage. Attempts to mimic the physiology of the human hand result in simple forms with limited movement, adaptability, and performance. ...

What would a super fuel-efficient aircraft look like; how far can we refine its aerodynamics; and what kind of performances, load capability and comfort can we expect from it?

The AGA-33 is a 250-passenger fuel-efficient twinjet that is optimized for 6000 km transatlantic missions. This aircraft will be constructed using known materials and mature technologies. This is something that can be done right now, and not “sometime in the future.”

To achieve better fuel-economy, the L/D (lift to drag ratio) has to be boosted by enlarging the wingspan, and reducing the wetted area. With a 68 meters wingspan, the AGA-33 aircraft achieves a L/D of 32. As a result, the fuel burn per passenger falls to 1.01kg ...

Personal flight has stayed an ojective since the Icarus story and Leonardo da Vinci. The problem is getting sufficient lift. The attempt to solve this problem here is through a hot air balloon effect of putting hot exhaust from a (possibly motorbike) motor into wing compartments through (empty) tubes which also serve as struts for a motorized flapping motion in line with bird/insect flight as described by Vol. IV of Sir James Lighthill's collected works (1997), including the Weis-Fogh Mechanism or other mechanism of lift. The wing compartment for each of the two wings, which may be around eight inches thick, contains three or more flaps on the top and bottom surface,which are closed on the downward part of ...

The invention relates to the use of the collision of matter and antimatter as a means of propulsion in a spacecraft, to the control system for said engine and to a block diagram of the connections for same, in which all of the functions are divided into modules. Said invention refers to a form of propulsion that is totally different to those know at present, which enables spacecraft to move considerably faster in outer space and to reach up to one third of the speed light owing to the controlled collision of matter and antimatter. The control system works in conjunction with the engine in order to control the collision and to maintain the optimal parameters for performing said ...

The separation of flow over a body such as an aircraft wing can cause substantial loss of lift and reduction in the overall fuel efficiency of the aircraft. Delaying or elimination of the separation of flow can help in decreasing fuel consumption and decreasing emissions, thus producing a more fuel efficient–greener aircraft.

Fluidic oscillators can be used as active flow control devices which produce oscillating output flow, which can be used for effective flow control. These oscillators use the phenomenon of Coanda effect (the tendency of a jet of fluid to be attached to the adjacent wall). A series of fluidic oscillators in an array can produce oscillating flow for an entire span of an aircraft wing. Fluidic devices ...

Who do you know that would like a safer, faster, more fuel efficient airliner that could carry more at lower costs, take off at less than 100 mph yet travel near Mach 1 with minimal drag penalty? This design has already been proven in NASA, hypersonic testing. The time to support this giant leap forward in design is now.

This is the next logical step in aviation design. Its natural stability and proven history make it most desirable for minimal flight testing and overall cost reduction. The design lends itself to adaptability. With the use of advanced composites, this structure can be pressurized for safe, human transport now.

With the latest in efficient design and technology, this plane is ...

The Beam Irradiance on Target System (BITS) is a high energy laser (HEL) sensor array that directly measures the beam irradiance profile of HEL weapons. The BITS is a sensor array composed of 105 sensors arranged in a hexagonal pattern over a circular area and is designed to withstand direct exposure to continuous wave (CW) lasers at threat irradiance levels. The sensor array spatially and temporally samples HEL beam profiles and is the only reusable and direct (on target) measurement system of its type. The BITS represents the state of the art in the directed energy test and evaluation HEL sensors.

The directed energy test and evaluation community required a reusable, direct (on target) detection technique to measure CW ...

The proposed project is about generation of instantaneously Ultra High Vacuum (UHV) [2] to deflect or damp the blast load of the high explosive explosions. This method can be used as standard countermeasure against any type of warfare explosions.
This project aimed to reduce the blast load caused by any type of the weapon explosions. After a very short time of the detonation, system reacts as a vacuum generator that pulls the whole blast load and throws away from the area to be protected. System reaction time has to be short enough to generate UHV before the blast reaches the area to be protected. Since the highly compressed air after detonation may have supersonic velocities [1].

A high explosive ...
