Since then successful inventions have included the following:
- CAT computer
(widely used for evoked potential studies, worldwide.)
- On-line Auto and Cross Correlator.
- Pulse Frequency Modulation tape recording and data transmission
(several patents)
- Color Ultrasound, and other ultrasonic means for imaging biologic structures
(several patents)
