Utilizing current LED monitor technology, incorporate it into both fabric and complex surfaces, combined with data processing of video imaging. The purpose of this is to project an image on both clothing and surfaces of objects replicating the background of an identified viewer.

For example, an object can be hidden from a viewer without camoflage. Using this approach, a viewer identified with a direction finder could direct a camera to video the view behing the object; projecting it onto the monitor surface facing the viewer. With the associated microprocessing capability, the object would blend into the background the viewer sees. As a result, the object would be completely invisible to the viewer.

This technology could be applied to personnel, ...

Reduction of drag and boosting of lift to drag ratio is of paramount importance to maximize flight efficiency. Body shape has a major role in producing drag. In order to reduce drag and increase lift to drag ratio I have successfully developed a new concept after spending several years to research. The concept is described below.

Using cycloid profile sideward acceleration smoothly changes from zero to peak then to zero so there would not by sudden impulses or momentum changes of fluid and sideward velocity of fluid smoothly changes from zero to peak and the to zero. This causes what’s known as 3D relieving, for example a cylinder has smooth up (y+) and down (y-) flow during a passage ...

The availability of high-performance Commercial Off-The-Shelf (COTS) electronics that can withstand Low Earth Orbit conditions has opened an avenue for wide deployment of CubeSats and small-satellites. Swarms of these small satellites offer whole new capabilities in Earth observation, global positioning and communication compared to a large monolithic spacecraft. These spacecraft can provide bigger apertures that increase gain in communication antennas, increase area coverage or effective resolution of distributed cameras and enable persistent observation of ground or space targets. However, there remain important challenges in operating large number of spacecrafts at once. Current methods require a large number of ground operators which poses challenges in terms of coordination and control and which prevents the technology from scaled up in cost-effective ...

For 30 years lean combustion has been known to lower NOx emissions and many programs outline its benefit and in its Tapps II Combusor final report submitted by GE for its GEnx Engine in 2013 it shows zero fractal components. If things are the same, a small but important change can be made. It was shown that fractal grids can increase turbulence by over 100% and higher (Geipel et al 2010). In the recent book “Fractal Flow Design: How to Design Bespoke Turbulence and Why” Springer 2016. Editors Yaschiko Sakai and Christos Vassilicos outlined a series of studies that show bespoke or “customized” turbulence is now possible and can play an important role in Lean Combustion.

This project is about doing an experiment on circulation of light. It is known that mirrors can reflect light and there is a device called the periscope used for this purpose. The mirrors of a periscope are fixed 45 degrees to reflect light. What if we place four mirrors at an angle of 45 degrees as seen in the picture and shine a light on one end as seen in the figure. Assuming that the media is ideal and the mirror can reflect 100 percent and if we move the light source away from the mirror faster than the speed of light, does the light rays keep circulating? This project is only some part of the project I am ...

A parachute canopy is supported at its central hole by a large ring that contains a centrifugal fan, which is mounted on suitable bearings attached to the ring. The fan is supported on bearings and is arranged for it to rotate about a vertical axis. Intake air is drawn in above the canopy by this fan, creating a low pressure which pulls the canopy upwards. This air is blown out radially below the canopy, The shape of the canopy turns the air-flow downwards, creating higher pressures inside the canopy, which increase its vertical lifting force. The motor that drives the fan is mounted below the canopy, with a vertical drive shaft between the motor and the centrifugal fan.

Innovation is a thin, flexible “Matrix Hinge." This hinge is novel in many ways; it is durable, lightweight, and continuous and is not like any other hinge. The hinge is excellent in tiny applications to large building construction base on the material used to make the unique configuration. The hinge is nonmetallic, non-conductivity, waterproof, rust free, easy to disinfect, any color, transparent, flat, airtight, non-binding, no recess required to be near flush, detachable, permeant, durable, won’t twist or rack, peel or tear, compact and economical. This hinge does not use pins, plates, grooves, unique plastic, or specific material to fold or to be molded. The new simple design addresses direct, indirect, lateral, uplift, and torque loads to provide a ...

Typical AR style rifles have a round or hexagon shaped tube that wraps around the barrel to protect the operator from the heat of the barrel during firing while simultaneously providing a location to mount additional accessories which facilitate the operation of the rifle such as lighting, aiming, etc. On most AR style rifle handguards, accessories are restricted to being mounted in four locations evenly staggered around the circumference of the handguard. An additional problem with the accessory rails that exist on the market is their inability to mount accessories directly beside one another, outside of the cardinal positions of 12 o’clock, 3 o’clock, 6 o’clock and 9 o’clock positions. This cylindrical handguard would enable the operator to mount ...

The Navy and Military Sealift Command use reciprocating analysis (RA) as a part of a wide portfolio of technologies to monitor the condition (CM) of the fleet’s large Propulsion and Ship’s Service Diesel Generator engines. The CM data is used to improve fuel economy and enhance the effectiveness of preventative maintenance activities. The RA “shots” are taken periodically by attaching pressure sensors to the indicator cocks, and the Crew Engineers moving a pressure sensor between sequential cylinders during collection. The Pressure Time (PT) data that is recorded is downloaded to the ship’s computer, then displayed graphically in various analysis software packages for interpretation. Some engine compartment environments are cramped and pose potential hazards to personnel during collection activities. With ...

Oasis on Mars
Natural disasters, wars-atom bombs, threaten human existence on earth. The only other planet in our solar system that offers suitable conditions for existence is Mars. The arms war is at it's peak. NASA, space research stations around the world and startup companies are already working enthusiastically to enable habitation in 2030 on Mars.

What will be the design of the habitat? How will it be built with minimum means, with a suitable environment for the first astronauts away from Earth? The environment should protect their mental and physical health, and act as a base for future city development. Here is where architecture comes into play.

Architecture on Mars is different. For the firs time, it deals ...
