Introduced: September 1968

Title

Titles differ between systems:

IPC: using opto-electronic devices, i.e. light-emitting and photoelectric devices electrically- or optically-coupled

CPC: using opto-electronic devices, i.e. light-emitting and photoelectric devices electrically- or optically-coupled (optical logic elements G02F3/00)

Full titles differ between systems:

IPC:

Logic circuits, i.e. having at least two inputs acting on one output; Inverting circuits > using specified components > using opto-electronic devices, i.e. light-emitting and photoelectric devices electrically- or optically-coupled

CPC:

Logic circuits, i.e. having at least two inputs acting on one output (circuits for computer systems using fuzzy logic G06N7/02); Inverting circuits > using specified components (, H03K19/003 - H03K19/0175 take precedence) > using opto-electronic devices, i.e. light-emitting and photoelectric devices electrically- or optically-coupled (optical logic elements G02F3/00)
