  • Optical detection in access control systems
    Patent number: 11841478
    Abstract: Detecting passengers traveling through a transit gate, includes transmitting a first beam from a first optical emitter on a side of the transit gate to a first plurality of optical receivers on an opposite side of the transit gate, and transmitting a second beam from a second optical emitter on the opposite side of the transit gate to a second plurality of optical receivers on the side of the transit gate in a direction opposite the direction of the first beam. Transmit intensities are adjusted based on learned patterns or drifts in the receive intensities of light beams. Detection times are reduced based on pairing additional optical receivers with a single optical emitter.
    Type: Grant
