  • Patent number: 9151865
    Abstract: A reflective photo-electric sensing system includes a transmitter for the transmission of light and a reflector for reflecting the light. The reflector being positioned in a far field. A light channeling device receives reflected light from the far field or from a near field and channels the received reflected light to a near field receiver or a far field receiver dependent on an angle of the received reflected light. An electrical signal is generated at the near field receiver or the far field receiver. A controller evaluates the electrical signal of the near field receiver and the electrical signal of the far field receiver and generates an actuation signal dependent on the evaluation.

  • Patent number: 7616895
    Abstract: A device and method for operating an optoelectronic safety sensitive edge (100) for the safeguarded motor-driven movement of a gate having a closing edge (141). The device has a deformable, hollow, elastic profile (110), a light transmitter device with a light transmitter (121a), and a transmitter control system (121b), by means of which at least one operating parameter of the light transmitter (121a) can be adjusted, a light receiver device (122) with a light receiver, the light transmitter device and the light receiver device (122) being coupled optically and electrically by the transfer of dynamic signals, an optical, dynamic coupling signal (K2, K2?, K2?) within the hollow profile (110); and an evaluating device (130) with means for detecting an electric, dynamic coupling signal (K2, K2?, K2?), the evaluating device (130), generating a release signal in response to the detected, dynamic, electric coupling signal.
