Input: Question: How old was the founder of Masimo when it was founded? Passage:Masimo is an American manufacturer of noninvasive patient monitoring technologies based in Irvine, California. The company sells more pulse oximetry to hospitals than any other company. Masimo was founded in 1989 by electrical engineer Joe Kiani, who was later joined by fellow engineer Mohamed Diab. Masimo invented measure-through motion and low perfusion pulse oximetry, known as Masimo SET (Signal Extraction Technology). Masimo has been recognized for its intellectual property and for being one of the most innovative companies in the medical device industry. The company went public in 2007 and is currently traded on the NASDAQ stock exchange under the symbol MASI. In 2011, Forbes named Masimo to its list of top 20 public companies under a billion dollars in revenue, based on earnings growth, sales growth, and return on equity. In 2012, Joe Kiani, founder, CEO and Chairman of the Board was named the Ernst & Young National Entrepreneur of the Year - 2012 Life Sciences Award Winner. Kiani was recognized for "revolutionizing the health care industry by taking risks to create and commercialize noninvasive patient monitoring devices, which include an array of sensors that lead to improved accuracy, a reduction in the overall number of false readings, and ultimately, reduced cost of care."
