McLean, Virginia-based n-Vision, Inc, a vendor of high-resolution 3D immersive display systems, has lost its chief financial office, Robert B. Hamilton, who is said to be leaving ‘to pursue other interests’. A spokesperson for the company said Hamilton, who is in his late fifties, is considering going into retirement. The company reported a net profit of $16,217 on revenues of $1m in the first quarter of this year, following two consecutive years of losses ($1.1m in 1997 and $4.6m in 1996). The chief financial officer of Advanced Technology Systems, Harry S. Katrivanos, is to stand in for Hamilton pursuant to a service arrangement between the companies, until a permanent replacement is found.
