DEVICE FOR TRAINING EYE ACCOMMODATION Russian patent published in 1996 - IPC

FIELD: medical engineering. SUBSTANCE: device has control unit 7 which signal starts operating generator 15 and counter 16. The signal enters switch 3 of decoding modes from output channel of counter 16. The signal enters also amplifier line 4 from the other output channel of counter 16 through multifunctional decoder 2 which is under control of unit 3. The signal from output of unit 7 controls operation of two switches 9 and 10 through commutator 8. Switches 9 and 10 commutate signal coming from pulse generator 15 through frequency divider 14. Control signals enter unit 12 from unit 11 switching pulsations on and from frequency control unit 13. Output signals from units 4, 9 and 10 control operation of digital indicators 5 and 6 synthesizing characters. EFFECT: enhanced effectiveness of training. 4 dwg, 2 tbl
