A low cost optical character recognition device is proposed as a peripheral for microcomputers. the device in conjunction with speech output will give a low cost reading device affordable by visually impaired individuals. the development strategy will focus on a feasibility demonstration of a low… More

Silicon is the semiconductor that is presently most generally used in the united states and worldwide for photovoltaic (pv) devices, power devices, and integrated circuit (ic) technology applications. a problem which is commonly noted is the presence of unwanted impurities in the single-crystal… More

The long-term goal of this project is the development of a full-page tactile display to create an effective interface between microcomputers and blind people. this connection will enable blind people to become more productive and independent by providing access to databases, communicationsnetworks,… More

Integrated gasification combined cycle (igcc) approaches to coal gasification require high temperature filters for removal of particulates directly after the primary reaction step. these filters must have high flexure strength during reverse flow cleaning. ceramic coatings forthe fibers promise to… More

Research on a novel processing technology to produce sheet materials from bulk solids is proposed. the principal objective is to develop a means to produce high quality, lowcost silicon ribbon. this new technology when developed will reduce the cost of silicon wafer production and respondto the… More
