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 ...

Water is very critical for survival and that is why you hear often on water saving awareness and researches that could help on saving water from big consumption to small consumption in households. The problem of water wastage is not because of awareness because people know when they waste water, they just do not have a habit of saving them. One of the places where water is wasted big time is in household activities like washing your dishes, your hands, brushing your teeth and other similar activities that require us to use the sink multiple times in a very few period of time. On average, about two gallons of water flow from a faucet each minute. Something as simple ...

Ever since the invention of electric power by Serbian-American inventor Tesla Nikola, electric power has been very critical for survival of human beings. Whether the source of the electric power supply is renewable or nonrenewable, you often hear the concept on the awareness of conservation of electric power or electric power saving and researches that could save electric power consumption. One of the places where electric power is wasted is at household level activities like overcharging your devices of any kind. Householders waste £134million a year overcharging gadgets such as mobile phones and laptop computers, according to a study in the UK. One in five Britons leave their devices plugged in once the battery is full because they are ...

"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.

After being ...

The cost of hospital ventilators has become cost prohibitive during our present Corona virus epIdemiic as hospitals, states, and countries compete to buy them from the limited supply available in todays’s market place. A safe emergency replacement for ventilators is here suggested. A compressor and accumulator feeds pressurized filtered oxygen or air to a multi electro-pneumatic valve array. A computer controller controls the variable sized opening of each valve controlling each valve’s own variable volume, pressure, and flow rate of oxygen. Oxygen is driven through an ultraviolet sterilizer then distributing the oxygen to many patient masks. An electro-pneumatic valve, as distinguished from, but very similar to, an electro-fluidic valve, can not only turn on the flow of a gas, ...

Pivot Materials manufactures bio-materials by using agri-waste into plastics and bio polymer. We have reduced the use of plastics from 10% to 100%. Our materials are used in Shipping Pallets, One-time use Disposables, Automotive, Packaging, and Housewares. Some of our initial projects have shown the CO2 reduction up 20% per part.

Our materials are sustainable, cost competitive and no special equipment is ...

A green means of generating electricity from the pitter patter of falling rain drops and sunshine is described here. A falling rain drop strikes at least one piezoelectric element (coated with multi-layer photovoltaic flexible thin films) of a micro-grid array comprised of many piezoelectric elements. The rain drop imparts its momentum from falling to the struck coated piezoelectric element(s) through its flexible coating converting the rain drop's kinetic energy to electricity. When a piezoelectric crystal is squeezed, deformed, compressed, bent, or struck, it generates electricity via the piezoelectric effect. The piezoelectric element can be a crystal, a ceramic, PZT, a plate, a wafer, scintered crystal mixture multi-layer sandwich, a stack, or a film. Each element is coated on top ...

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 ...

Waveco's Subwave solution is based on an invention patented in 2016 by Inge Bakke, the founder of Waveco. The Subwave turbine is hanging vertically about 100 meters under a buoy floating on the surface. When the buoy is affected by ocean waves, the turbine will alternately be lifted and sinking in the calm and dark water below the wave base, forcing the wings to exert torque on the rotors and generate electricity.

The solution has some important features:
• The energy conversion system will be far below the active wave-zone; hence it does not need to be designed for extreme waves.
• The surface buoy will be a very simple and robust structure that is easy to ...

Depending on the area and layout of the individual mine fire; one or more delivery tubes are drilled down to be close the burning coal veins. Temporary bulkheads may be necessary to force the Liquid Nitrogen into the coal vein. Once introduced, the extremely cold and incombustible gas will knock out two of the three legs of a fire triangle.

1) Reducing temperature and
2) Available Oxygen.

Thank you Kindly for your ...
