from 1979 1980, ledley , golab developed computerized electro neuro ophthalmograph (cenog). machine enabled healthcare providers automatically analyze ocular motility, important factor in diagnosis of neurological , ophthalmic disorders. cenog generated considerable media attention in 1980s, largely because served demonstration of feasibility of automated medical diagnosis.

while @ nbrf, ledley carried out work related computer design. in 1970, when moore’s law still relatively new idea, , when powerful computers had 1,000 2,000 logic gates, ledley wrote paper titled “realization of billion-gate computer” in speculated on capabilities of transistorized computer had 1,000,000,000 logic gates. proposed such machine would: 1) have no fixed logic design; 2) capable of redesign of own components; 3) able “self-heal.” billion-transistor microprocessors have been commonplace in personal computers since 2010, though these machines not dynamic (in terms of logic structure) ledley had predicted.

in late 1980s, ledley lead team developed bat, three-dimensional mouse allowed users interact objects in three-dimensional space (generated using stereo images).
