Through synergies in infrared sensing and drone platforms, we have found a new innovative way to detect hidden PFM-1 anti-personnel landmines. These particular unexploded ordnance (UXO) devices pose a difficult challenge to conventional landmine detection methods like metal detecting, because the mines are primarily composed of plastic and only weigh 75 g. As a remnant of the Soviet-Afghan War which lasted from 1979 to 1989, there are an estimated 10 million PFM-1 devices scattered throughout Afghanistan. These mines remain emplaced in isolated locations, frequently out of reach of demining NGOs and act to thwart local economic and social development. The PFM-1s are infamously referred to as “toy mines” as children often mistake the mines for toys and set off ...

Under “Discrete” I refer to the acceptance in Engineering [ and not only ] of π in the Form of :

4 /{SQRT[ Golden Ratio ]},
which is associated, indissolubly, with Microcosmos and Macrocosmos .

The proposed π keeps its “Irrational” form in powers and roots unchanged.

As it is difficult to anticipate truth of the many π values, obtained “Diachronically” by searching various theoretical methods [ without a controlling feedback to each method used- e.g for the cube root of 2 ( Unsolved Theorem by Ruler and Compass), theoretically we obtain 1.25992105 and, as a feedback check, find that the cube of this is 2], it is proposed, here, that one experimental method could be reassuring, as is ...

The disk shaped hand grenade will be a new design. The grenade will be made with metal. All components will be the same in this disk like basketball shape grenade but only difference is its disk shape.

It will be more aerodynamic due to its disk shape. It will occupy less space to carry out and will be very easy to throw. Range will be over 150 meters or more. Its blasting range will be more than any other grenade. The disk can be attached separately with any other kind of ...

An idea from 1985 now updated. Although direction back to balloons, drones are more flexible. Large wing area with solar cells, bent slightly to catch more light when the sun, off apex. 2 concepts ST-1, and ST-2. Concept can be enlarged for passengers. Concepts also useful for Mars missions, rather than helicopter. Drones to carry 100kg to 200kg equipent for surveillance, or Internet,TV transmissions to remote ...

I always had a wish to upgrade and accelerate the figth against a fire. In my country every summer we have many fires that burn large areas specially in windy days. Many times these fires are close to the sea and can be to areas difficult to approach. So it is ideal to use a drone for firefigthing (obviously no humans are subjected to danger) specially for areas where we take advantage of the water of the sea or lake. Also a drone can easily approach areas where people and vehicles cannot approach. Another advantage of using water from the sea is that the water supply is unstoppable. Imagine to have the possibility from a safe distance to drive ...

By sintering ceramic powder with metal powder under very high pressure and temperature, elastic and plastic deformable metal rich ceramic can be created. Although the metal the powder was added to the ceramic powder, thus sintered bulk ceramic does not show sign of metal by X-ray diffraction check and elastically and plastically deformable. In addition, high temperature resistivity of the ceramic is maintained. The ceramic created by this technique is thought to useful for gas turbine blades without cooling by air and can operate under higher temperature blade than the metal turbine blades now employed to raise the fuel efficiency much higher. Not only for aerospace applications, it can be used very wide area of industrial ...

EAS device full absolute time same code structure that uses a true full absolute time protocol. This improvement will better guarantee absolute time from year to year as well as preventing bad BLU or WTE BLA CEA alerts.The solution is simple. Others have proposed similar ideas but my idea does more with elegant simplicity. The first same code message is transmitted three times as usual but after the same code message station ID of sender the year is added and the originator' senders call letters are added to the message in the same code string. This is to ensure proper absolute date when absolute date required is set on the decoder.

For the validation issues in general false alarms ...

It is known that vertical flight is very costly from an energy point of view. To avoid the same disadvantage during forward flight it is obviously recommended to use mainly the wings to produce lift instead of the air impulse. This increases the efficiency, respectively the range or can reduce the total weight of the aircraft.

Winged Personal VTOL aircraft – WIP
WIP is is a practical one man aircraft powered by a battery package driving at least six ducted fans which each produce a straight jetstream of air. The ducted fans provide both vertical and horizontal thrust and rotation speed management of the ducted fans control the aircraft’s direction/rotation movements. The ducted fans use a thrust augmenter system ...

New propulsion type with thrust augmenter and new VTOL aircraft

The present concept aims to improve the disk loading value with around 15 - 20% and to reduce noise with around 20% over current ducted fan propulsion systems. This increases the hover efficiency and reduces the power requirement. The propulsion system mainly employs a multiple ducted fan arrangement with thrust augmenter creating a very efficient air distribution. The innovative ducted fans are used for both vertical lift and horizontal propulsion. Each multiple ducted fan is rotatable mounted between the fuselage and a side support. The propulsion system offers the following advantages:

-The thrust augmenter increases the volume of air propelled with a corresponding decrease in average air velocity.

-The ...

A new image processing technology, nearest neighbor deconvolution (US Patent 7912307), is able to enhance image spatial resolution beyond the diffraction limit.

This technology rewrites the point spread function (PSF) with nearest neighbor model, applies the Shift Theory in Fourier domain, and achieves higher resolution images with inverse Fourier Transform.

This technology is able to:

1. Dramatically reduce weight of imaging satellites.
2. Enable small aperture cameras to reach resolutions as high as large aperture cameras.
3. Find more details from existing images.

Feasibility of this technology was approved by experiment, and by applying it to several NASA space photos. The processed photos have shown some new features.

Basic idea of this technology was invented 10 years ago, but ...
