People in wheelchairs can't currently travel on airplanes in their own wheelchairs. Airlines are reluctant to give up the real estate and revenue on their aircraft. They must transfer twice from their wheelchair to an aisle-chair then to the airline seat in a difficult and dehumanizing process.

Our Freedom Seat design converts from a normal airline seat into a space where a wheelchair can be docked onboard an airliner. The process takes seconds and the wheelchair docking system is already used on buses and trains.

When not required for wheelchair accommodation the seat converts back to a normal revenue-generating airline ...

The purpose of the work: to increase and improve the quality of parts and assembly of gearboxes of vehicles, reduce the labor intensity and cost of manufacturing the gearbox, increase productivity in the assembly operation.

Project objective. To elaborate: the base table for mounting of all equipment, drive rotation, the bearing support for clamping the chuck, spindle assembly for securing the test site, stand for securing the device to control torque, the system of fixing the device to control the friction torque from the test duplexity bearing assemblies, the system of control number of revolution of the spindle.

Preload is one of the most important parameters that determine the reliability and durability of any structure. Preload is created during ...

What is HyDroneTM - A vehicle designed to operate in and easily transition between maritime subsurface, surface, ground, hover, and forward flight domains. HyDroneTM can operate in or back and forth between any or all of these domains during a single sortie. This allows a single HyDroneTM to perform missions that would otherwise require two to four separate vehicles with their separate attendant control and support systems.

How Does it Work – The transformational design is enabled by the Hybrid Advanced Mobility Propulsion System (HyAMPSTM) (US Patent 10,180,083, additional patents pending). The HyAMPSTM design acts as a ducted fan propeller in air or water and engages the ducted shroud to serve as a drive wheel on the ground. A ...

Present day energy such as fossil fuels, nuclear,solar, wind and others are either to dangerous or not dependable or what not. The idea I have come up with is "energy distancing". Build a thermonuclear generator, using the used fuel pellets from power plants, in a 1'x6' steel cylinder, to generate, at minimum, 5K electricity.

Drill a 30' well in the backyard by the utility entrance. Place the generator capsule at the bottom of the well and connect it to the utility cable with a proper interface. The generator buried in your yard will supply you with continuous power. Peak power will be supplied by the grid. If the grid is disabled by weather or accident you will still have ...

A single-handle water faucet comprises a hollow base which mounts on the top-back portion of a sink, a valve assembly, a handle for controlling the flow rate of water and the temperature mix of water, a spout securely attached to the valve assembly and extending upwardly from the top end of the valve assembly, and a nozzle for discharging water. The handle is positioned below the nozzle so that the water discharged from the nozzle can be directed to the handle and sprayed onto the handle by hand in order to facilitate the cleaning of the handle during a handwash session. In one embodiment of the invention, the handle is axially and longitudinally rotatable. In another embodiment of the ...

10% of women and 20% of men do not wash their hands when leaving a public washroom.

How do you avoid potentially picking up infections from them when grasping the handle to leave?

In ordinary life this device, which allows one to leave cleanly without any risk of contamination, can reduce the occurrence of infections like stomach upsets.

Medical personnel would find it particularly useful in public areas of hospitals.

However, in the current situation, as the movement restrictions are eased, the need to keep clear of covid-19, which can survive for several hours on the metal handles of doors, is really important.

It is a hook device, which is not novel, they do exist but have a major ...

Plastic waste pollution is an increasingly prevalent environmental issue around the world. Many companies produce plastic waste through their manufacturing processes, and resource-limited environments - isolated island populations, natural disaster locations, remote operations, and more - continuously bring in plastic products that end up as waste. In parallel to these issues, individuals in these remote environments often face the challenge of acquiring manufactured tools and resources. Additive manufacturing technologies enable users to solve complex manufacturing and supply chain problems, but these technologies continue to suffer from barriers such as cost, accessibility, and sustainability.

To address these barriers, re:3D developed Gigabot X, a 3D printer that prints directly from polymer pellets, flakes, or recycled regrind, allowing it to revive plastic waste ...

The Everglades is a subtropical wetland ecosystem spanning almost two million acres across central and south Florida.

This GPS Python Trap Drone Retrieval System will make the capturing of Burmese Pythons in the Florida Everglades viable and efficient. The snakes are devastating mammal wildlife in the Florida Everglades, and seriously jeopardizing the ongoing restoration of our amazing 'River of Grass.' There is only 1/3 of the original Everglades still left in existence. To date efforts to capture significant numbers of pythons has been largely unsuccessful. E.g., 1,000 hunters caught 68 pythons in one hunt.

The USDA has received a Patent for a live trap that targets large, heavy snakes, while sparing smaller native species such as rattlesnakes, and water ...

One out of three people in the world is exposed to earthquakes, and the number of people living in seismic areas increased by 93% in the past 40 years - 2.7 billion in 2018. Cities face a growing pressure from global challenge on resilience of structures and infrastructures to catastrophic natural events.

Seismic isolation is the most used technology to mitigate vibrations to buildings. This technology uses rubber-steel composite interposed between the structure and the foundations to divert the energy of the earthquake and to minimize interstory drift and floor accelerations of the above structure. However, while steel is needed to reinforce the composite, its presence limits the use of base isolation technology to strategic buildings such as hospitals ...

Here is proposed a new control framework for converters of renewable energy sources, based on choosing their operation mode – grid-forming or grid-following depends on the dynamic properties of a power system. Accordingly with the proposed definition of the power system’s dynamic stiffness (DS) are defining its direct (DDS) and quadrature (QDS) components. The values of these components let us estimate a disturbance’s impact on a power system at bus i, and also the power system’s inertia around bus i at this disturbance. So, using the DS we can estimate the dynamic properties of a power system in real-time, and locally for each need bus. Based on this information, proposed different applications DS for resilience planning at increasing renewable ...
