ST. CHARLES – About 31 jobs will either be lost or shifted out of the area later this year when a Florida company completes the process of integrating a business it bought from St. Charles-based DuKane.

In 2009, HEICO, the parent company of Sarasota, Fla.-based Radiant Power Corp, purchased DuKane’s Seacom division.

Seacom is described as “the world’s leading supplier of underwater acoustic locator beacons,” which are devices installed on commercial and military aircraft, as well as in other maritime and underwater applications.
