This is my undergraduate final project: a portable ultrasonography device, or the "portable USG". The background for this product is Indonesia’s high mother and infant mortality rate, which is mainly caused by lack of medical infrastructures that allow continuous pregnancy examinations, especially in isolated rural locations such as Irian Jaya. This portable USG is aimed to meet the need for early pregnancy examinations in isolated or poor areas of the country.

This is one of my undergraduate project in 1992. The Gas Pump design features a payment system that utilises magnetic cards similar to telephone cards which makes it easier for the consumer to purchase fuel.
