Engineering student develops automatic tyre pressure testing system

Philadelphia, Pennsylvania -- Daniel Lang, an 18-year-old first-year student in

mechanical engineering at Drexel University, Philadelphia, has developed a method by which motorists can measure tyre pressure at the fuel pump

automatically, according to a Drexel press release.

The system consists of a metal strip

which, when installed parallel to gas pumps, allows motorists to align

their tyres on treadles composed of strain gauges. It is capable of

determining whether all four tyres are properly inflated based on the

strain certain areas of each tyre apply to the sensors.

Lang has also developed three other

pressure testing systems based on cameras, infrared treadles and load

cell-based treadles. He is exploring options to sell his systems to commercial organisations, the Drexel release said.
