History of Technology Heroes and Villains – A little light reading Here you will find a brief history of technology. Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many personalities, eccentrics and charlatans involved. You may find the Search Engine , the Technology Timeline or the Hall of Fame quicker if you are looking for something or somebody in particular. Scroll down and see what treasures you can discover. Background We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind. Volta’s pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications. The electronics, computers and communications industries, power engineering and much of the chemical industry of today were founded on discoveries made possible by the battery. Pioneers It is often overlooked that throughout the nineteenth century, most of the electrical experimenters, inventors and engineers who made these advances possible had to make their own batteries before they could start their investigations. They did not have the benefit of cheap, off the shelf, mass produced batteries. For many years the telegraph, and later the telephone, industries were the only consumers of batteries in modest volumes and it wasn’t until the twentieth century that new applications created the demand that made the battery a commodity item.

What if the scan shows a problem? What is an ultrasound scan? An ultrasound scan sends sound waves through your womb uterus. These waves bounce off your baby as echoes. Hard tissues, such as bone, reflect the most sound waves and so make the biggest echoes.
Sometimes the results of a first trimester scan may be inconclusive or uncertain, and need to be combined with your clinical history and blood tests (serum BhCG). Some women need to return for another ultrasound scan a few weeks later to assess the progress of the pregnancy, or they may require another blood test (serial serum BhCG).
History Galton whistle, one of the first devices to produce ultrasound Acoustics , the science of sound , starts as far back as Pythagoras in the 6th century BC, who wrote on the mathematical properties of stringed instruments. Echolocation in bats was discovered by Lazzaro Spallanzani in , when he demonstrated that bats hunted and navigated by inaudible sound and not vision.
Francis Galton in invented the Galton whistle , an adjustable whistle which produced ultrasound, which he used to measure the hearing range of humans and other animals, demonstrating that many animals could hear sounds above the hearing range of humans. The first technological application of ultrasound was an attempt to detect submarines by Paul Langevin in The piezoelectric effect , discovered by Jacques and Pierre Curie in , was useful in transducers to generate and detect ultrasonic waves in air and water.
The Mosquito is an electronic device that uses a high pitched frequency to deter loitering by young people. Animals Bats use ultrasounds to navigate in the darkness.
Doppler Ultrasound The doppler shift principle has been used for a long time in fetal heart rate detectors. Further developments in doppler ultrasound technology in recent years have enabled a great expansion in its application in Obstetrics, particularly in the area of assessing and monitoring the well-being of the fetus, its progression in the face of intrauterine growth restriction, and the diagnosis of cardiac malformations. Doppler ultrasound is presently most widely employed in the detection of fetal cardiac pulsations and pulsations in the various fetal blood vessels.
The “Doptone” fetal pulse detector is a commonly used handheld device to detect fetal heartbeat using the same doppler principle. Blood flow characteristics in the fetal blood vessels can be assessed with Doppler ‘flow velocity waveforms’.
