    摘要: Provided is an LED display unit group, comprising: an insulation substrate, a front circuit board, and a back circuit board. The front circuit board is divided into pixel areas arranged in an array of 2m rows and 2n columns. Each pixel area comprises three A-electrode pads, three LED light-emitting chips of different light emission colors, and B-electrode pads corresponding to the three LED light-emitting chips. In each pixel area, the electrode A of each LED light-emitting chip is electrically connected to a corresponding A-electrode pad, and the electrode B of each LED light-emitting chip is electrically connected to a corresponding B-electrode pad. In the same column of pixel areas, B-electrode pads corresponding to all LED light-emitting chips are electrically connected to each other. In the same row of pixel areas, A-electrode pads corresponding to LED light-emitting chips of the same light emission color are electrically connected to each other.

    摘要: Eyewear including a frame, a projector supported by the frame, and a lens supported by the frame. The lens has a first surface facing an eye of the user and a second surface facing away from the eye of the user when the frame is worn. The lens also includes a waveguide defined by the first and second surfaces to receive light from the projector. An input light coupler and an output light coupler are on the first surface of the lens and at least one reflector is positioned on a second surface of the lens to redirect light received from the input coupler and/or the output coupler to redirect light having an angle of incidence with respect to the second surface of the lens that would result in that portion of the light exiting the waveguide through the second surface in the absence of the at least one reflector.

    摘要: Systems, devices, and methods for drone pairing are disclosed. Drones may be paired by configuring each of a first drone and a second drone in a drone pairing mode, establishing physical contact between the first drone and the second drone while in the drone pairing mode, determining an acceleration parameter for each of the first drone and the second drone related to the physical contact between the first drone and the second drone, comparing the determined acceleration parameter of the first drone and the determined acceleration parameter of the second drone to identify a match, and pairing the first drone and the second drone in response to the identified match between the compared acceleration parameters of the first and second drones.

    摘要: Systems, devices, media, and methods are presented for identifying emerging viewing patterns for visual media such as still images and videos. Emerging viewing patterns are identified by identifying visual tags for visual media viewed by users, selecting a subset of the tags by applying a taxonomy-based filter, generating pattern candidates from the subset, evaluating consumption metrics for each of the generated patterns, and ranking the generated pattern candidates responsive to the consumption metrics to identify emerging viewing patterns for the users.
