In extreme hot summer, many people, particularly the elderly, can suffer heat-stroke and die. For example, in 2018, there were more than 65,000 global deaths due to extreme heat wave. Therefore, air-conditioning is no longer a luxury but a necessity.
Air conditioners literally save lives and improve quality of life both at home and at work. So why are air conditioners not available everywhere? Present day air conditioners, invented in 1902, face a number of challenges. Firstly, they consume huge amounts of energy; secondly, they cause significant environmental detriment due to the use of chemical refrigerants; and lastly, to cool a desired location, they dissipate large amounts of heat to the environment; creating undesirable heat zones.

Conventional water-based ...

It is said that the main causes of sudden death in elder people are heart failures and risk of falling. Diagnosis and prevention of heart diseases and fall detection are more and more important in our daily life. In addition to increased population growth, online telemedicine systems are useful due to the possibility of timely and efficient healthcare services. The rapid growth in technology has remarkably enhanced the scope of remote health monitoring systems. Loss of consciousness and fall-induced injury is one of the leading problems faced by the elderly. They are the leading cause for the transfer of senior citizens from the comfort of their residence to assisted care environments. They also account for 40% of injury related deaths ...

passwordsFAST is an offline, compact, electronic password keeper. You just have to remember one simple password to access all other passwords. This allows you to have strong passwords without having to remember them, which, is the best defense against hackers. Data is encrypted using AES256 encryption which is combined with cipher block chaining and key stretching algorithms. The biggest distinction is the fact it's NOT CONNECTED to the internet so you can't put software hacking tools on the device. It takes the place of unsecure methods such as sticky notes, excel spreadsheets or having the same password for everything. Also, password managers and smartphones are all connected to the internet making them vulnerable to hacking. Some of the top ...
The purpose of the solar-silo is to decrease the geological footprint of solar arrays (using existing technologies) while maintaining maximum array output, eliminating solar tracking and reducing maintenance.

A solar-silo is a silo-shaped structure having a clear geodesic domed roof surrounding a solar array positioned around the inside perimeter with a clear cylindrical column containing a light refracting medium in the center of the structure.

Each geodesic segment of the clear geodesic domed roof has an attached Fresnel lens with its focal point passing through the top of the light refracting column (with only the top of the refracting column illuminated by the magnified light of the Fresnel lens). The refraction column consists of a closed clear cylindrical container, with a ...

Beddingo sheets are a two-piece fitted sheet simple system - a base and a sheet, which attached together for fast and easy sheet changes.

Once installed, the base will remain around the mattress and never have to be removed. Beddingo sheet then easily attached on and off, with velcro fasteners, for easy changing.

Beddingo sheets have 4 main advantages:
1. No need to ever lift your mattress again!
2. Corners doesn’t pop off, stay secure all night long.
3. All fabrics made from premium quality 100% organic cotton.
4. Takes half the time to change ...

Record-breaking amount of Sargassum is in the Caribbean resulting in the largest problem ever. The major problem it has brought are it piles up on beaches, sometimes many feet thick and begins to decay. The hydrogen sulphide that gets released smells like rotting eggs and many resorts had to close their doors. Since the species are Sargassum natans and Sargassum fluitans float they block sunlight creating a dead zone beneath them because plants under need sunlight to survive and the clean-up and removal of sargassum is an expensive task. This project proposes a new way to solve this problem. The best solution is a long term solution but the Caribbean economy depends upon tourism so it needs a quick ...

Earth exerts a gravitational force and pulls down every object that attempts to leave or escape it. Therefore, in order to break free from Earth’s gravitational pull, it is essential for a rocket to attain an enormously high speed. This velocity is known as the ‘escape velocity’. For Earth, the escape velocity value is 11.2 kilometers per second (25,020 mph); this means that you have to accelerate a rocket at 11.2 kilometers per second in order to make the orbit.

This project is about building a mechanism that uses gravitational force to launch space shuttles instead of against it to achieve the escape velocity with lower cost. This is done by integrating roller coaster principle, Newton law and existing ...

The problem statement chosen was to build a model that makes sure that the rules for the speed limit are followed in every road segment and thus reducing the possibility of accidents and ensures safer automobile systems.

Main motive for designing this model is to avoid accidents and alert the drivers about speed limit for safe travelling in every road segment. Most drivers are tempted to exceed the speed limit at one time or another. Speed has been identified as a key risk factor in road traffic injuries, influencing both the risk of a road crash as well as the severity of the injuries that result from crashes. Controlling vehicle speed can prevent crashes happening and can reduce the ...

This device uses GPS and a terrain/obstacle database to create a predicted flight path. When the predicted flight path detects an approaching CFIT threat, the device changes from a passive flight following mode, gives the pilot an aural warning and a visual threat display. The pilot gets a 3D visual picture of where the predicted flight path will hit the terrain/obstacle. By maneuvering the airplane, the pilot can alter the predicted flight path away from the terrain/obstacle. When the predicted flight path no longer detects a CFIT threat, the system returns to the passive mode.

What makes this system novel is that when a CFIT threat occurs, it shows the pilot a visual picture of the predicted flight path ...

Innovation
This is an attractive, affordable ‘human-amplifier’ in the form of a compact electric bicycle. It is disruptively innovative in ALL the key areas: size, weight, cost, ease of use and appeal. It has a new folding system that puts the clear, spoke-less wheels together to form a single ‘wheel’ with a telescopic handle to roll like most modern luggage.

Portable, the size and weight of carry-on luggage, it can easily become a ‘human-amplifier’
Riding it 'amplifies' walking effort by three to six times.
It can shrink the 30 minutes’ walk from the station to home, into an easy 7 minute 'glide' home and speeds up hills effortlessly. You can roll the device into your home where it ...
