The orientation of the cantilever may be actively controlled in one or two dimensions, thus adjusting the orientation of the optical waveguide. Actuation of the cantilever may be performed, for example, thermally and/or electrostatically. Orientation of the cantilever may be performed in such a way to align the optical waveguide with an optical device.

  • Patent number: 10880766
    Abstract: Embodiments of the present disclosure provide a method and an apparatus for detecting a characteristic sequence in a wireless communication system. The method includes: receiving, by a receiving end base station, an original characteristic sequence periodically transmitted by a transmitting end base station; detecting out, by the receiving end base station, a candidate characteristic sequence meeting a preset condition from the original characteristic sequence; determining whether the candidate characteristic sequence is a valid characteristic sequence; and detecting whether there is an associated event based on a preset rule according to the detected valid characteristic sequence. In this way, it is solved the problem that it cannot be guaranteed that the number of characteristic sequences falsely detected is reduced without increasing the missed-detection probability in a scenario of larger number of detections in the prior art.

  • Patent number: 10854096
    Abstract: Described are systems, methods, and apparatus for detecting objects within a distance of an aerial vehicle, and developing a three-dimensional model or representation of those objects. Rather than attempting to use stereo imagery to determine distances and/or depth of objects, the described implementations utilize range-gating, or time-gating, and the known position of the aerial vehicle to develop a three-dimensional representation of objects. For example, when the aerial vehicle is at a first position it may use range-gating to detect an object at a defined distance from the vehicle. The aerial vehicle may then alter its position and use range-gating to detect an object that is the defined distance from the vehicle at the new position. This may be done at several different positions and the resulting information and aerial vehicle position information combined to form a three-dimensional representation of those objects.

  • Patent number: 10828776
    Abstract: A control device includes a stop command unit for stopping an operation of a robot when a person comes in contact with the robot, and a speed limit unit for limiting the operation speed of the robot. A distance determination value relating to an accident caused by sandwiching a person is predetermined. The speed limit unit includes a model generation unit for generating three-dimensional models of two objects among the component of the robot, a hand, and object arranged around the robot, and a distance calculation unit for calculating the shortest distance between the models of the two objects. When the shortest distance is less than the distance determination value, the speed limit unit controls the operation speed of the robot so that the operation speed is equal to or lower than a predetermined limit speed.
