In the context of perimeter security, one-way traffic spike strips may be used to enforce directional traffic flows. However, these devices simply lack the kinetic stopping ability of a physical barrier. Furthermore, their protruding spikes impose a 5mph speed limit on passing vehicles which can hinder rapid/emergency egress.
Retractable physical barriers, such as swing gates, retractable bollards, or hydraulic wedge barriers have much greater kinetic ratings, however, they often require a human operator and they can be vulnerable to outside penetration when retracted (such as when allowing a vehicle to exit the premise). In addition, one must consider the ...
Terror threats across the world, soldiers and policemen fight in the front lines every day. 24 hours and 7 days patrolling is an important tactical operation to control a dangerous area. A robot, a robotic vehicle, or an autonomous driving car are more focused on specific task or civil transportation, they are not intended to be used as a bullet resist equipment. Neither an armored vehicle nor personal protection equipment can protect soldiers and policemen from multiple directions attacks. Soldiers and policemen expose to assault firearms when they get off the vehicle and fight against terrorists face to face ...
POLYHEDROHELIOTROPE SATELLITE OPTICAL TRACKING
By Panagiotis Stefanides
The proposed model [ PHOTO 1 and 2], when moving in space, is expected to reflect light of Sun rays from its mirrors, which will enable observers on Earth to receive them and track its displacements.
The Polyhedroheliotrope model is based on Invention and Conceptual Design of the “ Generator Polyhedron” [ PHOTO 3] By Panagiotis Stefanides*.
The Polyhedron**, a new invention [ referred to in published book : ISBN 978-618-83169-0-4, National Library of Greece ***, by Panagiotis Ch. Stefanides] of novel aesthetic architectural geometry design configuration, has Contour of dissimilar kinds ...
Till date very little has been reported about the issues of Hirakud Dam. Increasing deterioration of soil in the catchments is causing erosion of the subsoil, resulting in Sedimentation and Siltation, Largescale water-logging, seepage and unscientific water distribution system are only a few to name. In addition, the Flood control objective of the dam conflicts with the other objectives of irrigation and hydel power generation.
Various Research and Reports suggest that 43 percent of silt was assumed to be annually trapped in the reservoir. This has led to loss of the live storage capacity at an annual rate ...
The patent pending engine design incorporates 12 sets of cylinders, each comprised of two opposing and one air pump (supercharger) piston, arranged radially in a rotating-cylinder cam-driven engine that uses diesel or JP-8 and completes 48 power strokes per revolution. Magnets are installed around the rotor periphery which, combined with coils in the radial housing, effect an integral motor/generator for starting, reverse, rapid acceleration, power generation, hybrid operation, and occasional silent running. Finally, the 12 vanes of a centrifugal cooling fan are incorporated between cylinders, and the fan’s intake air used to cool engine oil distributed via a centrifugal ...
The Rapid Cooling Station (RCS) and Integrated Cooling Ensemble (ICE) together provide a comprehensive, cheap, and easy-to-implement solution to one of the largest issues facing soldiers, firefighters, and other suited responders in the field today: heat management. Based on the requirements of protective equipment, significant heat builds within a subject’s suit even under moderate conditions and effort. In order to remove this layer of hot air and keep the subject cool, two methods are proposed.
The first, called RCS, is the “stationary” solution. In this scenario, a compressed air source accompanies the operator on scene. When the operator seeks ...
In our world today we are faced with many challenges regarding lethal weapons used by law enforcement and the military. I have designed a non-lethal polyhedron plastic sphere that creates an ear-piercing siren and temporary vision disturbance. Our brains are stimulated in multiple ways. When adrenaline kicks in during acts of rage or rioting the mind has tunnel vision. The idea is to create a mental interruption of the assailant in these highly escalated situations with loud sirens and debilitating light flashes from super bright LED lights. The theory is by diffusing the thought process in circumstances such as: ...
Both Military and domestic police forces use FlashBangs as entry devices, often called distraction devices. They allow for safe entry in situations where the occupants may be armed as the function of the devices gives the entering forces a few seconds before occupants gain their senses and reorient to their surroundings.
It is unfortunate though that the pyrotechnic nature of the FlashBang also has caused injuries and deaths. Injuries actually to a police office at least on one occasion.
To create a valued distraction intense enough but yet relatively safe, I have devised the Hi Frequency Entry Device. This unit ...
This type of transportation system is able to run, hover on the road surface and fly in the air. Vehicle has combined features of car-airplane-train-skater-hovercraft.
To drive the vehicle in forward direction following are options:
1. Four-wheel power drive
2. Height adjustable arm’s wheel drive
2. Thrust generated by propellers or other suitable thrust engine
3. Combination of wheel drive and thrust drive.
To lift and hover the vehicle in upward direction following are the options:
1. With the help of wings/fold-able wings
2. Vehicle without wings/ or body's airfoil shape work as wing to generate the lift force.
Vehicle can adjust its height while travelling ...
My Idea is about a drone with rifle. Some areas where for surveillance or any place where terrorist are present we can send this drone. Major 2 concepts to consider: recoil of gun and how to recognize face. Recoil surely imbalances the drone. So there are two ways to avoid this: [1.]By using hydraulic cylinders bed. [2.]By using spring bed. In first technique, (fig.1) by using few small hydraulic cylinders we can avoid backward movement of gun. When gun is fired shock is absorbed by hydraulic which negligibly affects drone’s stability. [2.]Using spring bed(fig.2), similar as hydraulic, spring bed ...
