Abstract: An antenna structure includes a feed section, a ground section, a first radiator, a second radiator, and a third radiator. The first radiator and the second radiator are both connected to the feed section. The third radiator is connected to the ground section. The first radiator defines a first slot. A second slot is defined between the second radiator and the third radiator. The third radiator defines a third slot. The third slot communicates with the second slot. Current is coupled from the first radiator and the second radiator to the third radiator via the first slot, the second slot, and the third slot.

Abstract: The present invention discloses a head-mounted display and a video data processing method thereof. The head-mounted display comprises: a video input module, a distortion processing module and a video output module. The head-mounted display divides each image frame in a video into a plurality of image blocks of symmetry according to a graphic correspondence of a distorted image after a distortion processing, performs a distortion processing of any one of the image blocks, and obtains data of the current image frame after the distortion processing according to the graphic correspondence. By dividing the image frame into blocks, the technical solutions provided by the present invention realize a transmission and processing of image data in the video in a block unit, in substitution of the solution in a frame unit in the prior art, and avoids the problem of limited internal storage space.

Abstract: A shift control apparatus of a manual transmission is disclosed. The shift control apparatus includes: a shift lever including a rod; a shift lock limiting the movement of the rod; and a controller which compares a speed of a vehicle with a predetermined critical speed of a predetermined gear and controls the shift lock. When the speed of the vehicle is greater than the critical speed, the controller controls the shift lock to be located on a shift path of the predetermined gear, and then limits the movement of the rod in a shift direction of the predetermined gear.

Abstract: An antenna structure includes an antenna holder, a feed unit, a grounding unit, a first radiating unit, a second radiating unit, a third radiating unit, a parasitic unit, and a coupling unit. The feed unit and the grounding unit are positioned on the antenna holder and are spaced apart from each other. The first radiating unit and the third radiating unit are both electrically connected to the feed unit. The parasitic unit is electrically connected to the grounding unit. The first radiating unit couples with the second radiating unit and the parasitic unit. The second radiating unit further couples with the coupling unit and is grounded through the coupling unit.

Abstract: An exemplary wireless communication device includes a circuit board, a metal board, and a display module. The circuit board includes two groups of connecting terminals. The metal board is located on the circuit board and includes two metal bodies. The display module is located on the metal board. One metal body is electronically connected to one group of connecting terminals. The other metal body is electronically connected to the other group of connecting terminals.

Abstract: An antenna structure includes a feed portion, a ground portion, a first radiating body, a second radiating body, and a third radiating body. The feed portion is connected to a first shared portion of the first radiating body. The second radiating body further includes a second shared portion connected to the first shared portion. The first and second shared portions are included in a third radiating body together with a combining portion between the second shared portion and the ground portion. The first radiating body receives and sends wireless signals of a first frequency band, the second radiating body uses a second frequency band, and the third radiating body uses a third frequency band.

Abstract: An antenna structure includes a main antenna, a parasitic antenna, a matching circuit and a switching circuit. The main antenna includes a feeding strip and a first radiating strip coupled to the feeding strip. The parasitic antenna includes a grounding strip and a second radiating strip coupled to the grounding strip. The second radiating strip is positioned adjacent to and apart from the first radiating strip, and further configured to electromagnetically couple to and be parasitically fed by the first radiating strip. The parasitic antenna and main antenna cooperatively generate at least one high-frequency resonate mode and a low-frequency resonate mode. The matching circuit is electronically coupled to the feeding strip. The switching circuit is electronically coupled to the matching circuit, and configured to regulate an inductance value of the matching circuit output to the feeding strip, thereby regulating a central frequency of the low-frequency resonate mode.

Abstract: An adhesive film that includes a first region having a first hardness, and second regions disposed on opposing sides of the first region and having a second hardness that is greater than the first hardness.
