The Hanvon e-book reader won the only top prize at the fifth Beijing Innovative Invention Competition last week.

The device not only displays electronic books, but can also identify and save hand-written messages.

Some 19 gold, 30 silver and 60 bronze medals, as well as 517 citations for excellence, were awarded at the ceremony.

The youngest winner was an 8-year-old boy who designed a solar power generating system for small home appliances.

The 11-month competition received more than 1,000 entries from 26 provinces and cities, 75 percent of them from individuals.

The entries covered a wide range of fields including environmental protection, electronic information, new energies and materials, modern agriculture and biomedicine.
