  • Lens for eye-tracking and device with such a lens
    Patent number: 11226682
    Abstract: A lens for eye tracking applications is described. The lens comprises a first protective layer with a first surface, arranged to face towards the eye to be tracked when the lens is used for eye tracking. The lens is characterized in that the lens further comprises a supporting layer and a second protective layer with a second surface, arranged to face away from the eye to be tracked when the lens is used for eye tracking. The supporting layer is arranged between the first protective layer and the second protective layer, and the supporting layer comprises at least a first opening between the first protective layer and the second protective layer. At least one electrical component arranged extending through the first opening.
    Type: Grant

  • Method and optical network for front haul protection
    Patent number: 10079638
    Abstract: An optical system is provided comprising a first node and a channel drop add device. The first node is configured to transmit data onto an optical fiber in a first line direction. The channel drop add device (501) is adapted to receive and add channels onto the optical fiber thereby transmitting the data into the first and a second line direction. The network further comprises a second node configured to form a transmitter/receiver function. The second node is configured to receive data on said optical fiber from said first and second line directions. Further, the second node is adapted to synchronize received data from said first and second line directions by delaying the data signals seeing the shortest delay, by a delay device.
