How do speed traps work?

How do speed traps work?
Speed trap is a device used by the officers to measure the speed of your vehicle in a particular area where speed limit is enforced. Radar or laser is used to measure the speed while speed trap is a stationary thing in itself.
The element of stealth is used in the working of a speed trap and can surprise the driver running their vehicle more than the speed limit. The policeman using speed trap mostly remains hidden from the sight so that they cannot be located and can easily trap the speed. Mostly these devices are used in the blind corners, near a turn or under an underpass. In such regions officers have the laser gun which is a radar to trace the speed of moving vehicles that pass from there.
Another type of speed trap is placed on the highway passes or off ramps. Generally a driver drives by looking straight in front and he cannot recognize a laser gun or radar in the hands of an officer pointed towards their vehicle and tracing its speed. To know that a vehicle has passed through a speed trap is a flashing light is seen in the mirror of rear view.
Radar speed traps are used by one officer at a time. One traces the speed of vehicle and informs the other about it. Then driver can be investigated ahead.
Stationary speed traps are also used and are also called as photo radar camera. They are placed near the road or inside another vehicle of the officers, parked near the road. This speed trap not only measures the speed but also take the photographs of driver and license plate as the vehicle passes through the area of speed trap. This helps to find the owner through the photographs of license plate. Now the speeding ticket can be posted

ROBOT used in a complicated heart operation.

CHENNAI: A rare heart surgery using a robot was recently perormed in a city hospital on 23-year-old D Vijayakanth, an auto driver from Vellore.

Dr R Ravi Kumar, director of the institute of cardiovascular disease, robotic surgery centre at the Chettinad Health City who controlled the surgery, said on Friday that the robotically-assisted procedure involves replacing both the mitral and the aortal valve simultaneously. The surgery, done by a three armed robot, took four hours and cost Rs 2.25 lakh. "The best part about using a robot in cardiac surgery is that the patient's heart need not be opened and the surgery can be done using a small 4cm incision. This is not possible with normal surgeries without a robot," said Dr Ravi Kumar.
Robotic surgery, which is fairly new in the country, can be used for a gamut of medical procedures, said Dr Ravi Kumar. "It requires a lot of precision and intense training because though the robotic hands do the surgery, it has to be controlled by a trained surgeon. One of the biggest disadvantages is the lack of sensory perception which is there when the surgeon actually does the surgery himself," said Dr Ravi Kumar.
Talking from New Delhi where he is chairman and managing director of Medanta the Medicity, Dr Naresh Trehan, who pioneered robotic surgery in the country, said from a three-armed robot in 2002 to a four-armed robot now, robotic surgery has come a long way. "We have an institute where we train doctors to perform robotic surgeries. There are people who are doing colon surgery, prostate surgery and cardiac surgery using robots almost on a daily basis," he said.
The biggest advantage in this field, said Dr Ravi Kumar, was the time of recovery. He predicted that in the next 10 years almost 80% of the procedures in the country would be done using robots.

Always look for simple solutions.

The Empty Soap Box
One of the most memorable case studies on Japanese management was the case of the empty soap box, which happened in one of Japan's biggest cosmetics companies. The company received a complaint that a consumer had bought a soap box that was empty.
Immediately the authorities isolated the problem to the assembly line, which transported all the packaged boxes of soap to the delivery department. For some reason, one soap box went through the assembly line empty.
Management asked its engineers to solve the problem. Post-haste, the engineers worked hard to devise an X-ray machine with high- resolution monitors manned by two people to watch all the soap boxes that passed through the line to make sure they were not empty.
No doubt, they worked hard and they worked fast but they spent whoopee amount to do so. But when a workman was posed with the same problem, did not get into complications of X-rays, etc but instead came out with another solution.
He bought a strong industrial electric fan and pointed it at the assembly line. He switched the fan on, and as each soap box passed the fan, it simply blew the empty boxes out of the line.
Moral of the story: Always look for simple solutions. Devise the simplest possible solution that solves the problem. So, learn to focus on solutions not on problems. "If you look at what you do not have in life, you don't have anything; if you look at what you have in life, you have everything.
