BIOGRAPHY - S. L. HOU, Ph.D. (Updated 5/24/2017)
Dr. Hou is the inventor of the patented returnles multi-pressure fuel injection delivery system developed for internal combustion engine. The system uses one or two fuel by-pass paths with flow restraint to control fuel pressure off-line in four configurations. A binary valve is used to select the pressure level. The system is capable of creating multi pressure levels and instant pressure switching. For an example, a vehicle with 230 HP engine in highway driving may operate like a 75 HP vehicle in city driving to save fuel. Less fuel reduces exhaust and smog in metropolitan areas. The same vehicle (equipped with air accessory) may deliver a burst of extra power at 320 HP to accelerate quickly for a sport-car-like performance. That allows the smaller Eco-Friendly Engine capable of instant super power on-demand for driving in metropolitan areas.
TMC Co. specializes in product development and OEM sales. Dr. Hou, president of TMC, was a management consultant to Executive Managing Director (R&D) of Ricoh Co., Ltd., and later to Executive Vice President of Konica Corp. Both have Headquarters in Tokyo. TMC helped their non-impact printer development. TMC also served as the liaison office in the U.S. as the sole OEM sales and importer of printer products from Konica Corp. Expanded its business from start-up to $25 million (in OEM shipment value) before handed over to their US subsidiary. At Dataquest Conference, Dr. Hou met a R&D Vice President of renowned multi-billion dollar fuel injection system manufacturer in Greater Detroit Area. Under consulting arrangement, we discussed a potential joint development project applying multi continuous jet fluid system technology to fuel injection. That started the development of fuel injection system for internal combustion engine.
Prior to TMC, Dr. Hou was R & D Director, Advanced Systems Group, Mead Corp. directed continuous jet array printers development. The technology was licensed to IBM, Kodak, Scitex and HP. Then he was Director of Non-Impact Printing, Exxon Enterprises, Exxon Corp. Helped the start-up of a new operating division in Exxon Enterprises. The technical professionals hired by Dr. Hou at Exxon Enterprises later developed solid ink jet printer, which was licensed to Tektronix, Xerox and Hitachi. Dr. Hou is the author of 34 technical publications and inventor of 30 issued patents. His joint review paper in Ink Jet Technology co-authored with Dr. R. D. Canahan, presented at IEEE-IAS Meeting, was the first using droplet generation mechanism to classify ink jet, and named Continuous Ink Jet for the industry. The paper was later published at IEEE Transactions on Industry Applications. Dr. Hou graduated magna cum laude from National Taiwan University with B.S. in Electrical Engineering, received M.S. in Electrical Engineering from University of Minnesota, and Ph.D. in Applied Physics from Harvard University. He was a recipient of Fulbright Scholarship and Gordon McKay Fellowship.
