| titleOfInvention | Failsafe train vehicle control signal threshold detector apparatus |
| abstract | ABSTRACT OF THE DISCLOSURE A more failsafe signal voltage threshold determin-ing apparatus is disclosed for operation in a train vehicle control system, and which utilizes the forward voltage drop characteristic of an input light emitting diode of an optical isolator device as a train vehicle control signal threshold reference. The detector transistor of the optical isolator device provides an output control signal in response to an input train vehicle control signal applied to the light emitting diode which has a voltage level high enough to overcome the liqht emitting diode voltage drop. |
