Dr. Zhang, who is also fluent in Mandarin Chinese, received his Ph.D. in Nuclear Engineering from the Massachusetts Institute of Technology and a Masters degree in Electrical and Systems Engineering from the University of Connecticut. Having over 24 years of experience in research and development, systems engineering, software development, business development, and distribution channel management in the Asia-Pacific theatre represents a well rounded skill set for the wide range of sales growth initiatives planned for the region.

Richard Meyerhoff commented, “China has been our most productive sales territory and we expect this trend to continue. Through the efforts of our leading distributors there, we continue to receive multiple unit orders and anticipate fulfilling the majority of our current backlog to this region in the 3rd quarter. We also believe the upcoming 2008 Olympics, to be held in Beijing in August, could provide additional near term opportunities for sales of our security products. The establishment of a local support office in this region reaffirms our commitment to existing and new customers there, along with the opportunity to expand our capabilities in this important part of the world. We are fortunate to have retained Dr. Zhang to head our business development efforts in the Asia-Pacific territory. His background is well-suited to promote the sales of our security products and the development of new strategic partnerships. We continue to evaluate other international territories where the distributor network could benefit by this type of direct support from the Company.”
