The revolutionary FrictionLess-Gear© [FLG] and Continuously Variable FLG [CV-FLG] provide absolute minimum product size, mass/weight, friction, cost, and energy/fuel requirement, resulting in highest performance - maximal operating speeds, specific torque capacity, reliability, safety factor, longevity, energy output in power generation and solution overall - at any scale.

The Continuously Variable FLG [CV-FLG] is NOT a friction device like all others and therefore significantly superior.

The concept is an innovative reformulation of gearing theory based on the idea of a roller bearing which can act as both in the same unit, obviating the need for a bearing in some devices in which it is installed. The large number of engaged teeth gives it a tremendous torque capacity compared to conventional ...

Although elevator plunges are rare because brakes and cables provide fail-safe protection, free-falling elevators still happen at some point. Elevator free-fall occurs when the cables lifting the elevator snaps due to overload or when the cables that lift the elevator is faulty and left to operate unknowingly. These are just some of the many factors that could cause free-falling elevators and often cause drastic results like serious injuries or even death. There are some documented free-falling incidents on the internet like youtube and many other blog sites that can be read with accompanying videos to be watch. There are millions of people using elevators everyday around the world, so, as an early safety countermeasure, I would like to suggest ...

Machines have contributed their presence in cultivation which has greatly reduced human effort and by removing weeds so that there is no consumption of nutrients from soil by weeds. In conventional method of cultivation, tractors cultivate i.e. remove weeds only the area along its pathway and in addition human labor is required to cultivate the area between successive plants which becomes tedious. The team conducts research in several areas including survey of existing methods of cultivation and farm mechanizations. This leads to the decision to design and fabricate Inter Row Cultivator for Horticulture fields, when attached to present cultivators which removes weeds between the rows as well as between successive plants simultaneously.

Cultivation of large fields manually is time ...

Low Cost Cluster Computer Produces Underwater Acoustic Fields

Research and development of fields such as seabed composition, communications with in situ oceanographic instruments and marine biology will be greatly assisted with the development of a low cost, cluster computer capable of generating and graphically displaying underwater acoustic fields. An intuitive user interface goes a long way in making the modelling system simpler and easier to use by both veteran researchers and student assistants as well.

The product builds on a popular ARM V8 based system (a 1.2 GHz, 64 bit, quad core processor) which scales very easily into a multiple CPU cluster while still retaining its low cost production benefits. In a teaching / learning, research environment, unlike current commercial systems ...

One key issues regarding coffee production is the bean selection process, which is a tedious task that nowadays is often manually done. Since traditional selection techniques are based on size and density, most of them do not consider faded, mottled, and blotchy beans. However, beans with these characteristics should be discarded because they affect coffee quality.

The latest technology employed for coffee beans selection uses laser equipment. However, these kinds of machines a very expensive, and therefore they are only used by large producers. Due to the fact that small producers do not have access to this technology, their market competitiveness is drastically reduced.

Current technology favors the use of low cost tools that can be applied to automate ...

NASA's Langley Research Center offers a novel lifting and precision positioning device with hybrid functional characteristics of both crane-type lifting devices and robotic manipulators. The design of the Lunar Surface Manipulation System (LSMS) allows for fine positioning with complete control over both translation and rotation of the payload. In addition, the design permits several other operations using a wide variety of special purpose tools, such as a bucket, pallet forks, grappling devices, sensor and visualization packages, and dexterous robotic arms that can be quickly added to the tip. NASA is seeking development partners and potential licensees.


* Precise positioning for a broad range of heavy lifting operations
* Compact for transport
* Cost-effective
* Scalable ...

Every object in an environment is subject to air flow and so subject to the aerodynamic forces like drag, lift. Objects should be designed properly to bear these forces and their effects easily by using aerodynamics, streamlining principles.
But tall objects have some limitations:
1. These objects like towers, chimneys cover more surrounding space because of their supports.
2. These objects become imbalanced when one of their support fails.
3. These objects require multiple number of supports.

Main parts of design are:
Elastic sheet (suitable modulus of elasticity according to design).
Elastic pillars (integrated in building).
Sliders (movable and fixed as per need).

In the image, an elastic sheet has been mounted on an elastic pillar’s ...

Hi, my name is Lutf and I am going to design a turbine in the right of way pipe line going towards the house with pressure. For this I have selected a site in my village. The head of the pipe line is about 45 meters high and the length of pipe line is 120 meters long. Section of my turbine is attached here.

But here I have a problem. I want to fix the turbine in way of pipe line and think is it possible that the water flowing in the pipe produce movement in the turbine and flow through the outlet pipe for the village as I think the water store inside the turbine will cause ...

The objective of this project is to make a controller based model to avoid accidents in blind curves. Here we used a sensor for sensing the vehicle. Collision avoidance systems are especially useful in bad weather conditions. The sensors in the car would be capable of detecting the poor conditions and would inform the driver on how to drive in them. For example, because fog affects visibility, the sensors would recognize this and alert the driver of any dangers that lie ahead, like a windy turn or another car, giving the driver enough time to slow down, allowing him to escape from what could have been a bad accident.

A collision prevention system for a vehicle has a brake ...

In ring-yarn-spinning, the ring and traveler combination is the limiting factor for the maximum spindle speed.

The important factors in the design of ring-traveller are (1) the traveller stability during its high speed rotation while being clipped onto the ring flange and (2) the space for yarn passage between ring and traveller.

The high rotational speed of the traveller creates a considerable amount of centrifugal force resulting in a very high contact pressure of the order of 35 N mm-2. The extremely low area of contact between the ring and traveller with this level of centrifugal force results in the generation of considerable amounts of heat. The temperatures reach values as high as ...
