People with asthma might soon be able to predict an attack, thanks to a device developed by a student at the University of Pretoria. Moses Kebalepile, a doctoral candidate in inhalation toxicology, won first prize at the Technology Innovation Agency Inventors' Garage Competition, at the Innovation Summit, at Cape Town Stadium at the weekend.Kebalepile's device, the size of a cellphone, might be on the market in 2017.It is intended to detect signs of an impending asthma attack and alert the user."If you are likely to get an attack, you will be better prepared," said Kebalepile. "You'll have your medication and pump with you."The device warns users of environmental pollutants, such as carbon monoxide, and identifies common allergens . It tells users which allergen triggers their attacks.Technology has advanced considerably over recent years but our healthcare systems are lagging, said Kebalepile."This has triggered an interest, a passion, to contribute and be part of healthcare - but at the forefront of research."For his innovation Kebalepile won R25,000.Others showing their innovations included Josua Nghaamwa, who created the Master Terminator, a prototype satellite dish made of foil and intended to improve internet speed and signal strength for cellphones.Nghaamwa took home R5,000 after receiving 792 likes on Facebook for his invention.Load-shedding inspired Christo Rossouw to invent RE_LIT, said to be an environmentally friendly light for use during blackouts ...
