This drive mechanism does not use chaindrive or shaftdrive but has efficiency as chaindrive (in terms of gear teeth engagement) and requires less frequent maintenance. Extra length requirement due to pedals is removed and length of bicycle can be further reduced by using smaller front wheel.
Welding technologies are fundamental to fabrication and ubiquitous within manufacturing. Laser welding has found wide application for the joining of precision metal components and high-speed production due to the intense laser heat source. Low penetration or “conduction mode” welding is well controlled, depositing energy and melting at the surface of the metal. However,
Manned aircraft are quite heavy and cumbersome in some areas of aviation use. For example, aerial photography in cartography or forestry, spraying fertilizers or pesticides on medium-sized crop fields. And in these cases, unmanned aerial vehicles are a rational solution.
Drones give more secure, faster, and cheaper strategy for performing a variety of missions.
The main problem of space exploration are the costs due to an obsolete technology after sixty years we are still with liquid thrusters, plasma propulsion and relegated to military uses and it will take another twenty five years before it is released to the public utility if it will never be released given the terrorism problems.
The automotive greases have various metal additives to ensure the properties and retention under various extreme working conditions. However, depending on loss of these elements the grease looses its properties.
At Narbis, our mission is to improve people’s lives by helping them to get the most from their brains through the use of safe, affordable, consumer friendly technology that delivers lasting results. Narbis is a platform technology, based on patents originally developed by NASA, delivered through a set of “smart glasses”
Problem:
As a mechanical engineer with previous journey of work in different industries of which air pollution is a common factor that necessitates the protection of the workers respiratory tract, we used to wear face masks that I always believed not efficient enough to prevent dust from entering the lungs through the nose.
False alarms are a common problem with invisible laser based sensors.
In border areas it just creates panic to identification whether it is a human being, an object, dust, an animal or some vehicle moving across the border.
The proposed solution will work to neutralize false alarms through accurate identification.
