There are numerous high rise buildings in most cities situated either by narrow lanes or only their front sides face the main (wide) road and the other three sides face narrow lanes. lf fire breaks out in such narrow lanes facing buildings, much time is required to douse or control it, because presently-used 50-60 mtrs ladder-Loden vehicle can not enter into that lanes, leading to huge casualty through spreading the never-ending fire flames to other adjaust high-rise building. Such an incident has already happened a few month ago in Kolkata (lndia). To address this problem, l have invented such system by which 50-60 mtrs or more high ladder-loden vehicle can enter into those narrow lanes.

This system ...

Basic limitation of Traditional (Open) Differentials is accompanied with their large masses and costs. This limits use of differentials to the places, only where either requirement is must or economy is not a problem. However use of differential is to fulfill the need of relative angular speed between wheels on same axle. This scene creates when a vehicle has to take a turn or when it comes on a rough surface to drive or even when steering at high speeds. Also, traditional differential also face operational problems when traction is far different on both of wheels. This can be problematic when one wheel does not have enough traction, such as when it is in snow or mud. The wheel ...

The blue crab, Callinectes sapidus, is a keystone species that plays an integral ecological, economic, and sociological role in Chesapeake Bay. Concern for declining populations in this species is considerable and efforts to raise awareness regarding the need to conserve these precious natural resources is being advanced through use of the Quick-Capture Attended Waterman Trap (Grab-Crab™).

The “Grab-Crab™” is an invention comprising a new means/method of catching individual marine species through use of a new ‘attended waterman trap’ designed to a.) Enable conservation during the acts of sport and recreational fishing; and b.) Limit the catch size to “one” specimen during said use. For detailed information about the invention see: http://grab-crab.weebly.com.

Use includes singular collection of individual crustaceans, ...

Gesture recognition has a goal of interpreting human gestures that can originate from any bodily motion or state but commonly originate from the face or hand. It helps in building bridge between machines and humans than primitive text user interfaces or even GUIs (graphical user interfaces), which limits the majority of input to keyboard and mouse.

The project deals with the design and fabrication of a gesture controlled robotic arm. The robotic arm is operated & controlled wirelessly with the help of hand gestures, which transmits signals to the robotic arm through a Leap Motion device rather than controlling it manually through a conventional remote controller. The Leap Motion controller is a small USB peripheral device consisting of two ...

NASAs Kennedy Space Center has developed a novel ruggedized housing for an electrical or fluid umbilical connector that prevents intrusion of dust, sand, dirt, mud, and moisture during field use under harsh conditions. The technology consists of a pair of hand-sized protective umbilical interface housings, each containing a connector with an integrated end cap. When the end cap covers the connector, the connector is protected. Each housing has a unique lever assembly connected to the end cap that, when squeezed, flips the end cap up to expose the connector. When in the up position, the two end caps face each other. To mate the connectors, the levers on both housings are squeezed, raising the end caps, and the two ...

The Shutter Valve is a quarter turn, compact and fully piggable high performance valve that is based on a simple interlocking three petal design. This design gives it the ability to seal at very high pressures just like any other high performance valve. Unlike other high performance valves, it has a compact design that can be disassembled by a trained technician for field maintenance or repairs.

The valve is designed to work with all standard size flanges and pipes. Users can maintain the same standard face to face dimensions of their existing valves (‘plug-and-play’).
Among the Shutter Valve’s several features, it boasts precision flow control. With its design based on a mechanical iris, the Shutter Valve controls flow ...

Extreme advances in science and technology have opened up unlimited possibilities for development and creation of new products. By using a single hardware platform consisting of the latest embedded control and acquisition system with re-configurable FPGA technology plus an elaborate sets of data acquisition and controlling modules combined with a customized and adaptive circuit that can be interfaced to virtually any machinery, electronics and electrical devices to control, manipulate and monitor variety of diverse tasks.

The customized interface circuits was developed for a category of specific application such as Industrial, Medical, Consumer Electronics, R&D and are refer to as personality modules. As an example, we have developed a high speed/high power-switching module that can control and manipulate power ranging ...

In this undertaking we intend to develop an automated mobile robotic arm, for medium duty work (for a payload of 50-100 kg ).

1. Even though many robotic arms ( completely actuated through hydraulics ), they have either been built for very heavy duty works ( Diggers, forklifts ) or are stationary in nature, that is the base of the arm is fixed. Hence in our project we intend to develop the robotic arm on a mobile platform for medium duty work.

2. From application point of view we are developing the for the construction industry. For example, it is tough for a construction worker to carry out some activities at high altitudes due to various human reasons or ...

Smoothly interlock two independent power devices has been a challenge for mechanical designers. Toyota Prius with its synergy technology demonstrated a successful example. By using a planetary gear box, Prius is able to coordinate the interlocking between engine and motor smoothly, however a little heavy and expensive.

Induced Magnetic Clutch (IMC) is designed to smoothly interlock axles of two rotational power devices such as engine and motor. Faraday's law states that moving a coil near a stationary permanent magnet causes an induced current to flow in the coil. The induced current can be maximized if the coil is shorted. Similar to a stepping motor but in reverse (generator) mode; IMC uses motion differential between two rotational axles as power ...

A caster where the swiveling portion is internal. There are two vertically disposed, horizontally spaced-apart rollers located on a horizontal roller axle mounted in a yoke attached to the bottom of a central shaft. The central shaft has two bearings supporting it with two central core spacers. The spacers on the inside diameters of the bearings have angled holes that are offset by 180 degrees.

The inner central shaft lies in a vertical plane which is centered on the caster but the center line of the center line of the inner central shaft is angled with respect to the center line of the device. This allows the shaft and spacers to rotate if the ball tries to roll in ...
