  • Publication number: 20240358214
    Abstract: A robot cleaner including a cleaner main body configured to travel and clean a cleaning area, a sensor case arrangeable on the cleaner main body such that while the sensor case is arranged on the cleaner main body, the sensor case is configured to cover a sensor for detecting an obstacle in the cleaning area, and a sensor collision detector configured to detect an impact applied to the sensor. The sensor collision detector includes a bumper connectable to the sensor case which covers the sensor such that while the bumper is connected to the sensor case, the bumper is moveable and at least a portion of the bumper is arranged along an outer circumference of the sensor, a detecting portion to interact with the bumper to detect a collision of the sensor case, and wherein the bumper and the detecting portion are on a lower side of the sensor.

  • Patent number: 12052885
    Abstract: An display device including a substrate, an organic light-emitting diode, and a thin film encapsulation layer. The organic light-emitting diode is disposed on the substrate. The thin film encapsulation layer is disposed on the organic light-emitting diode. The thin film encapsulation layer includes at least one inorganic layer, at least one organic layer, and a first refractive-index control layer. The at least one organic layer is alternately disposed with the at least one inorganic layer. The first refractive-index layer is disposed between one of the at least one inorganic layer and one of the at least one organic layer disposed adjacent to each other. The first refractive-index control layer has a refractive-index variation ratio per unit length (?n/nm) from about 0.001/nm to about 0.002/nm along a direction from the organic light-emitting diode toward the thin film encapsulation layer.
