The White Star electric toothbrush is a product that is aimed at making kids enjoy brushing their teeth. At the heart of the concept is the notion of helping others, so for every brush sold, one is donated to those less fortunate.
Description:
BZ200 is a novel, high-performance, thin, lightweight, polarization-insensitive, and wide-angle metamaterial RF absorber. It absorbs up to 99% of electromagnetic waves from 1 to 18 GHz (L to Ku band) as well as 35 and 94 GHz, without scatter.
With the recent development of low-cost means for harvesting water from the ambient air, more widespread implementation of such technologies is needed, especially in areas that typically do not receive much rainfall. The existing technologies typically rely on wired electricity or other power sources to be implemented.
Background :
When an emergency braking situation occurs, people panic to control the vehicle to avoid the accident. But unlikely we should not be able to control the vehicle (refer Fig 1 to 5 without wind catcher). Why? Because all our primary, secondary,
The turbine is based on the principle of aircraft. A body with a shape as an aircraft with a wing with attack angle of less then 15 degrees. On the other side a similar wing but upside down.
The lifting force is acting in opposite direction.
The problem
The higher power consumption in a home is for heating. According to recent survey about 60% of energy use in an average home is for heating water and for space heating.
Problem:
Highway vehicle accidents during inclement weather due to decreased visibility, and inefficient rubber windshield wiper mechanisms.
Solution:
Several embodiments are shown of a proposed system that uses a centrifugal compressor/impeller,or a mini-multi-stage turbine to draw in fresh,filtered air.
Said compressor/turbine can be driven by a belt,
The single greatest barrier to escaping poverty in Africa is the lack of roads.
Over 600 million people, living on less than $1.25 per day, grow the food they eat and if possible they grow extra crops to pay for clothes, schooling,
Of the 38,000 level crossings (Rail-Road Intersections) in India, 50 % are unmanned. There is a steady increase in the number of accidents (about 35 per cent of the train accidents) occurring at unmanned level crossings (ULC). Apart from disrupting rail and road services, loss of lives, vehicles,
Flight passengers having smart phone with WiFi can be identified and in-flight amenities serviced easily and quickly at seat level resolution (0.5m) with 90% accuracy.
