Safety and Security

Modern fabrication techniques permit manufacture of economical personnel and package security scanners integrating traditional metal detection with high-resolution ultrasound imaging of dense materials, such as explosives, hidden in clothing or small packages. currently deployed systems for security imaging are large, expensive, fixed installations with large power requirements, providing whole-body images susceptible to abuse, and undesirable doses of electromagnetic radiation to personnel being scanned.

The concept proposed provides a lighweight, portable, low-power solution for rapid screening of personnel and packages without exposing examinees to millimeter-wave radiation, or misuse of full-body imaging through clothing. it can be manufactured with standard semiconductor fabrication methods, and affords flexibility in location and routing of acquired images for examination. persons and packages can be vetted ...

A highly successful innovation to increase highway safety was the introduction of water-filled crash barriers at various high-danger locations. Many of these barriers are cylindrical is shape with a detachable cover. They are made of an easily crushable/deformable material and are filled with ordinary water. The theory of operation of these barriers is simple: The incoming vehicle comes in forceful contact with the barrier and begins to crush it. The rapid deformation of the container causes the horizontal kinetic energy of the vehicle to be transferred to the vertical kinetic energy of the water as it is projected upwards from the container, thereby slowing the vehicle. Several crushable barriers are positioned in front of each other to make sure ...

“L.I.B.E.R.O.” is a patented fire fighting system which offers particular safety characteristics since it is not an obstacle to navigation. It has been thought to be used in open spaces such as airports, heliports, helipads as well per subways, harbours, oil and industrial sector. This is a distinctive feature which allows the fire fighting system to be available in any accident condition, since it does not protrude above the ground and does not create obstacles during the landing and take off runs, which may occur on and even out of the of runway or by the edge of the just mentioned one.
The system L.I.B.E.R.O guarantees the fire extinction in the first seconds, basic to save human lives, ...

Knock, knock, knock! As a homeowner, I get visits from home security companies. As a father and a husband, I want to do everything within my power to ensure the safety of my family. However, current commercially available home security systems are rather cost-ineffective and just very passive electronics. Service normally requires a multi-year contract with costly monthly payments, and even then may not provide any protection in the case of an intruder (more on this below). Utilizing inexpensive hardware and advances in pattern recognition software algorithms, I propose a family of intelligent home security systems as follows.

The simplest device is an intelligent appliance timer that automatically learns the daily routines of the owner. It has a relay ...

Military/Police/Security Forces need cheaper, yet just as effective NIJ level IV protection from heavily armed adversaries. The Salamander Research And Development design is lighter, cheaper and “greener” to produce; as my design does not require a Kiln/Sintering oven to produce “plates”. My design is also very flexible as it has very few limitations to potential sizes or shapes. Initially my idea was conceived as replacement Chest Trauma Plates for body armor. Later, it will be available for vehicles and buildings.
The market for my design is quite large. The US Military market alone is a minimum of 150,000 units. The Police and Security forces, while smaller, are still significant.
My design is a laminated composite which uses ceramic components ...

Sudden Infant Death Syndrome (SIDS) claims the life of nearly one out of every 200 children born worldwide. As of today, no explanation has been offered for this phenomenon, and no solution has been found…yet.

System:
The SureChild: LiveSensor system comprises a monitoring system consisting of a thin, padded sensor belt, and a receiver unit. The sensor belt loops around the patient’s chest and is snugly secured in place with a piece of Velcro sewed to one end. The unit monitors the patient’s movement and respiration as they either move or expand their chest during respiration via an integral sensor embedded in the belt. If movement or respiration stops, the system will emit an alarm intended to either startle ...

LONG RANGE FIRE DETECTION AND RESPONSE
WITH UNIQUE OPTICAL DETECTOR

Approximately five billion dollars in US revenue is lost annually due to open area fires. Millions of acres of forest, many buildings and other properties are destroyed. Tragically, many brave firefighters and countless wildlife are lost. Worldwide the numbers are staggering and add additional carbon loading in the atmosphere beyond all the fossil fuel burned. Early detection of open area fires is typically performed by manned observatories, random reporting, space and aerial surveillance. These methods, while valuable, lead to unnecessarily long reporting times, low coverage, and rapid spread of wildfires. Optical flame detectors exist but typically experience high false alarms and low flame detection sensitivity in open areas ...

The Lund Variable Velocity Weapon System, or LVVWS, is a variable velocity non-lethal projectile launch system that uses a commercially available combustion gas in a single cycle engine to launch impact projectiles to deter or incapacitate an opponent.

This microprocessor-controlled weapons system is designed to launch projectiles at velocities appropriate for the distance at a minimum of two rounds per second. Magazine capacity is currently 15 rounds, which may be increased with simple design modifications. Fully loaded with the magazine in place, the final configuration of the LVVWS will weigh under 5 pounds, has minimal firing recoil and functions at extreme temperatures ranging from -15oF to +120oF.

Classified as a ‘green’ weapons system, ...

There have been many types of brakes to stop what's moving. From that there is one braking system that is known as magnetic brakes. These brakes are being used in the Trams and Railways.
These Brakes operate on the principle of Eddy current Losses, i.e when a conducting wheel is rotating between the two magnets the reverse force is generated on the rotating wheel in opposite direction to the motion of wheel. That makes the wheel stop. But the concept used here in this type of magnetic brake is a little different.

In this project we are using electromagnets to repel the brake pad. The brake pad will be attached to a High Power Permanent Magnet called NdFeB. ...

For those who want to participate, an add-on sensor to your PDA and/or Cell Phone that can sense the presents of volitile material can be designed. Once installed and activated, this information along with GPS coordinates could be feed into a Homeland security data warehouse for analysis. If the data indicates a gas station or fueling a lawn mower at home, then the data could be scrubbed. However if the sensor indicates a response for a mass transit or other public area, a flag can be raised to have this investigated. Other variations on this theme can be employed such as stationary locations in public areas for sensing, ...
