BTL Fellows Inc. is a company started by Martin P. Lepselter to develop technology based on the patents he has
been granted or are pending. For example, U.S. Patent Number 5,469,021 describes a Plasma flat screen microbridge
display suitable for HDTV. The issuance of these patents is an important indication of the uniqueness of the
microbridge technology, and is deemed by potential investors to have important advantages over other technologies.
The microbridge, also known as the air bridge, was originally invented by Lepselter in the early 1960's as an
outgrowth of the Beam Lead Technology, invented by him while at Bell Telephone Labs. The present day technology
known as MEMS is an outgrowth of his Beam Lead Technology as is the MMIC System used for high-speed devices.

A particularly universal technology, part of all modern silicon devices and invented by Lepselter, is the Silicide-Silicon
metal-semiconductor contact and Schottky Diode.
