One hand replacing two-hands to perform dual fastener fastening or loosening, the “1 hand DUAL FASTENER MANIPULATION DEVICE" can be used to manipulate two fasteners with the same axis of rotation and to manipulate the fasteners of the same axis of rotation separated by the intermediate material, and the spacing distance can be freely adjusted according to the size of the separated object.

In order to successfully join the two fasteners together, one of the fasteners must be rotated in the first direction and the other fastener must be prevented from rotating or rotating in the second direction at the same time. Typically, the process is accomplished using two separate wrenches or other fastener engagement tools, where one or ...

"CLOCKVID-20" is a voice controlled, subtle, home assistant which helps loneliness. This encourages people in self-isolation (who are discouraged from staying at home during lockdown) to unlock their social side.

COVID-19 is the largest pandemic in over 100 years. Nearly half a million people have fell victim to Coronavirus. From this more than 3000 people have died within the past 3 months as a result. Growing at such an exponential rate, it begs the question, why did it take such a long time for authorities to take action? Local governments have been enforcing (or in some cases, advising) their citizens to quarantine themselves and participate in the act of social distancing. This is where CLOCKVID-20 can help.

Nowadays desertification is no longer a purely ecological and environmental problem, but also an economic and social problem, which brings poverty and social instability to human beings. For those threatened by desertification, it means that they will lose their most basic subsistence -- a lack of food. Accompanying flowerpots are designed to grow crops and improve plant survival in desert areas. On the basis of preventing wind and fixing sand, increase economic income to improve living environment for people in desertification areas.

All the details on how these work are described in the ...

Ambient Updraft Power Converter

Air moves up because of relative heat and density. Density is caused by the distance from the center of the earth and the amount of air on top of the air. The Ambient Updraft Power Converter (AUPC) uses both of these means with a vertical duct. Air is more dense at the bottom of the duct than it is at the top of the duct. The air is cooler at the bottom of the duct and warmer at the top of the duct. The density and the difference in temperature both move the air up. The AUPC also uses a duct with a larger diameter at the top and a smaller diameter at the bottom ...

The proposed innovation is a sustainable, cost-effective and scalable flow battery that can store excess renewable energy in water (H2O) and table salt (NaCl). I have named this the BlueBattery. It is a combination of two well-established technologies: [1] Electrodialysis (ED), which uses electricity to desalinate water with the help of special ion-exchange membrane. ED produces a stream of concentrated salty water and a stream of freshwater from brackish water. [2] The reverse is also possible. One can perform Reverse Electrodialysis (RED), i.e. mixing salty water with fresh water to produce electrical energy. Renewable energy sources are intermittent; this means that electricity generation using these sources fluctuates. To supply the world with 100% renewable energy, energy storage is indispensable. ...

Capsule Vaccine is a simple, disposable vaccine syringe designed initially for the people of Africa. The biggest feature of this vaccine syringe is that it is simple and convenient to operate. Users can make their own injections, which no longer require a large number of professional medical staff to participate, and can effectively save human resources. The disposable and safe syringe also can reduce the risk of medical infection.This vaccine syringe is convenient and hygienic. The location and population are not limited, which will help to improve the prevalence of vaccines and medical conditions in depressed areas such as ...

Rentable electric scooters are often found in many large city centers and on college campuses for use as environmentally friendly transportation. Unfortunately, The Journal of American Medical Association reported that 40,000 injuries and 29 deaths are related to e-scooter accidents. The safety concern causes many people to fear e-scooters and some cities to ban the use of this valuable mode of transportation.

The Collision Alert Technology for Scooters (CATS) is an “active safety” solution integrated into rental electric scooters. CATS uses sensors and controls to detect potential hazards in the path of the e-scooter. CATS then alerts the e-scooter rider of such hazards so that they can take action to avoid a collision. The CATS solution identifies hazards like ...

The recent coronavirus outbreak worldwide created an emergency involving all countries In order to help fight the virus one of the most important early activities is to detect potential carriers through the body temperature monitoring, by individuating those with body temperatures higher than 37.5C.

In order to do a mass screening in short time and at a distance we are proposing the following system:

-A carrier
In our case an unmanned platform, a small airship (15/20mt) that can fly permsnently powered by a PV film to generate solar energy for its electric engines during the day and producing hydrogen for night utilization through a fuel cell system

-A sensor
A powerful infrared sensor, similar to those utilized in airports ...

Underwater divers may swim in waters with limited visibility. Commercial divers may operate at depths where sunlight does not penetrate.

Sonar images could be presented on a organic led emitting diode screen which replaces the diver's normal mask. The proposed mask covers the entire view of the diver. If the diver switches off the sonar, the visor is transparent.

Graphics could be added to the much like an aircraft head up display. Critical information such as air supply or directions could be presented to the diver. If the system included and inertial navigation unit, it could significantly increase the safety of ...

As it becomes apparent that the COVID-19 virus can be exhaled as an airborne pathogen, it becomes equally important to protect oneself from inhaling the virus in its bioaerosol form.

Proposed is a downdraft visor, the device worn as shown provides a steady downdraft stream of filtered air across the wearer’s face. A rechargeable battery unit powers mini-fans to draw in ambient air through a milli-pore HEPA filtration cartridge directing it downward in front of the wearer’s face.

The constant stream of filtered air directed across the front of the wearer's face at 50ft/min provides sufficient airflow to prevent exhaled aerosolized droplets of the COVID-19 virus entering the user’s airways via the nose and mouth into the lungs.

The device can be ...
