PROBLEM STATEMENT
Common symptoms of neurological disorders include numbness, leg pain, spasticity, muscle weakness, and loss of range of motion, which further lead to impairments in balance, gait, and functional ability.
Toe extension strength (TES) of the big toe, often ignored among other muscle strength outcomes,
Most aircraft composite repair has to be done in a controlled environment .Therefore the damaged parts need to be removed and sent to a shop to perform the proper repair.
To extract professional-quality espresso, it requires 20Bar(290psi) pressure. And, mechanically it requires a water pump to disperse the hot water onto ground coffee.
In a conventional espresso-making apparatus, electric-powered water pumps for indoor use, and hand-pump-powered espresso makers have been widely used. However,
This application is designed to allow for safer travel in low light conditions for motorcyclists.
Due to the low cost manufacture of this unit it will allow for an easy uptake among the general riding population.
Wireless power generating computer mouse and mousepad used to harvest mouse movement using a triboelectric nanogenerator. The power produced by the mouse motion on the mousepad is used to power the mouse.
Power generating mousepad and wireless mouse that are self-powered using triboelectrification.
Mr. Richard Phillips Feynman, a famous scientist, introduced a Brownian ratchet in his book “The Feynman Lectures on Physics” (see Figure 1). The Brownian ratchet is also referred to as Feynman’s ratchet, Feynman’s thermal ratchet and the like.
I have invented a Thermoelectric Generator with electrical power of 5,000 watts AC. The generator is the size of a bread box and weight is 15lbs. It is made of bismuth-tellurium P&N semiconductors arranged in a circular or square Thermopile. I researched,
When there is the need to change the blade pitch of the propeller of a helicopter, there is the problem of the strong natural coupling of the rotation of the regulating shaft with the rotation of the propeller hub, which in fact is a carrier.
The POWERBLoK system can replace the Lead, Cobalt, Cadmium, and Lithium used in common batteries with no thermal runaway risks.
Additionally per the 01/26/21 Bay Area Air Quality Management District (BAAQMD) assessment of the UCAP Power POWERBLoK,
