“It's really difficult to get security at the terminal,†says Sampriti Bhattacharyya, an undergraduate student at the Massachusetts Institute of Technology for mechanical engineering. “How do you check everything?†The inspectors need to patrol all the cabins and lockers under the deck. Make sure there are no hidden things. In early September, she and her mentor, Harry Asada, professor of engineering at the Massachusetts Institute of Technology, presented a completely new solution when participating in the International Conference on Intelligent Robots and Systems. What they propose is an inspection and detection robot (EVIE) called the Ellipsoidal Vehicle. This is an underwater robot that uses ultrasound to detect the possession of smuggled goods. Smugglers usually hide their cargo in secret compartments in the hull. Such bays are generally small, and port security does not have the facilities and time to inspect each boat. However, EVIE's own ultrasonic technology can detect the hull cavity, if you find the cavity, it is likely that the smugglers used to hide the compartment. The diameter of the EVIE is about 20 cm. The plastic body is divided into two parts. Six water jet propulsion devices are installed in the upper hemisphere. The EVIE can travel at a speed of 3.2 kilometers per hour. The lower hemisphere is a waterproof structure in which all electronic components are placed—battery, motion sensor, CPU, radio station and camera. equipment. The development team made the bottom of the ball robot a plane so that the EVIE could counter the flow of the river bed. Now robots can already be remotely controlled, but researchers think that one day robots can be programmed to work autonomously.
Calcium Hypochlorite is an inorganic compound with formula Ca(OCl)2. Calcium Hypochlorite Granular is the main active ingredient of commercial products called bleaching powder, chlorine powder, or chlorinated lime, used for Water Treatment and as a bleaching agent.This compound is relatively stable and has greater available chlorine than sodium hypochlorite.It is a white solid, although commercial samples appear yellow. It strongly smells of chlorine, owing to its slow decomposition in moist air.
Calcium Hypochlorite Granules is commonly used to sanitize public swimming pools and disinfect drinking water. Generally the commercial substances are sold with a purity of 65% to 73% with other chemicals present, such as calcium chloride and calcium carbonate, resulting from the manufacturing process. As a swimming pool chemical, Pool Calcium Hypochlorite is blended with other chemicals less often than other forms of chlorine, due to dangerous reactions Boric Acid Flakes with some common pool chemicals. In solution, calcium hypochlorite could be used as a general purpose sanitizer,Titanium Dioxide but due to calcium residue, sodium hypochlorite (bleach) is usually preferred.
