this is the Technology Report.(Music)Cameroon is experimenting with Africa's first mobile systemto send a cardiac, or heart signal over a wireless network.The system will give much needed medical assistanceto heart patients in rural areas.Cameroonian Arthur Zang invented the device called the Cardiopad.He was just 24 years old when he invented it.The Cardiopad is a touch screen medical tabletthat enables heart examinations to be performed.The results of the tests are sent wirelessly to specialistsin other parts of Cameroon who can interpret them.Simplice Momo is a 55-year-old heart patientin a rural area of Cameroon.He says the Cardiopad saves him time and money.He says it is too costly and difficult for himto see a heart specialist in the city.Cameroon has a population of about 22 million people.But the country only has 40 heart surgeons.Most are in the cities of Douala or Yaounde.Sometimes the heart experts neededcan only be found outside the country.Apolonia Budzee is a nurse at Saint Elizabeth Cardiac Center.She says the device will permit doctorsto send patients' medical information to specialists in Europe.Arthur Zang started the Cardiopad project five years ago.The young computer engineer said he needed more trainingand $45,000 to develop the device.His family did not have the money.Banks would not give him loans.So he shared his idea on social media.The president of Cameroon, Paul Biya,answered the appeal with money for the project.Mr. Zang also received free online trainingfrom an engineering school in India.The Cameroon scientific communityhas recognized the Cardiopad as extremely effective.The device costs about $4,000.The government of Cameroon has not been ableto provide the device to hospitals in need.Most of them lack internet and enough electricity.But the Cardiopad testing at the Bafia Hospitalis gaining attention and may get the assistance needed.Mr. Zang says he has had private investors contact him.But he is more interested in investors who share his vision.That vision is not of money,but of better ways to help improve people's lives.And that's the VOA Learning English Technology Report.
