ECG

Electrocardiography

-It gives useful information about the functioning of the heart.

-An initial breakthrough came when Willem Einthoven, working in Leiden, Netherlands, used the string galvanometer that he invented in 1903.

-Einthoven assigned the letters P, Q, R, S and T to the various deflections, and described the electrocardiographic features of a number of cardiovascular disorders. In 1924, he was awarded the Nobel Prize in Medicine for his discovery.-His idea is still used nowadays.

The Kidney Dialysis

-It was invented by Willem Johan Kolff in 1943.

-It is also known as haemo dialysis.

-It is used to provide an artificial kidney for those people whose kidneys are damaged.

-It refines the blood of the person who uses it.

-The patient’s blood is pumped through the dialyzer, and when it is cleaned it is returned back to the body.

-Generally the patient needs to go to a dialysis centre 3 times a week for a 3 to 5 hour treatment.

-BUT! studies have demonstrated the clinical benefits of dialyzing 5 to 7 times a week, for 6 to 8 hours.

The Traffic Enforcement Camera

-It was invented by Maus (Maurice) Gatsonides in 1958 (Gatsometer BV).

-It is a system including a camera and a vehicle-monitoring device to detect and catch the cars stepping over the speed-limit.

-The first systems were introduced in the late 1960s used film cameras to take their pictures. From the late 1990s, digital cameras began to be introduced.

The Milking Robot

-It is also called a milking machine.

-It was invented by the firm Prolion in 1987.

-The teat cups are attached to the cow's teats, then the cups alternate between vacuum and normal air pressure to extract the milk.

-The milk is filtered and cooled before being added to a large bulk tank of milk for storage. I’m lovin’

it! :)

The Compact Disk (CD)

-A Compact Disc (also known as a CD) is an optical disc used to store digital data.

-It was originally developed to store sound recordings exclusively, but later it also allowed the preservation of other types of data.

-Audio CDs have been commercially available since October 1982. In 2010, they remain the standard physical storage media for audio.

-It was invented by Philips (Eindhoven, Netherlands, on March 8, 1979)

-In fact James Russell invented the compact disk in 1965. However, the compact disk did not become popular until it was manufactured by Philips in 1980.

-The first test CD was pressed in Hannover, Germany, in 1981.

-In August 1982 the real pressing was ready to begin.

-Early the following year on March 2, 1983 CD players and discs were released in the United States and other markets. This event is often called as the "Big Bang" of the digital audio revolution.

It is a lamp…

-The first CD to be manufactured was The Visitor by ABBA.

-The first band to sell a million copies on CD was the Dire Straits, with its 1985 album called Brothers in Arms.

-Originally they wanted CDs to be the successors of the gramophone record, but they became data storage media.

- In June 1985, the computer readable CD-ROM (read-only memory) and, in 1990, CD-Recordable were introduced, also developed by both Sony and Philips.
