  • Publication number: 20160303880
    Abstract: A method of manufacturing and detecting an anti-counterfeiting mark includes steps as follows. For manufacturing an anti-counterfeiting mark, a first ink, which has a contrast enhancer and a lecithin solution with a first concentration, is provided. Then, the first ink is used for drawing an anti-counterfeiting mark on a target object. For detecting the anti-counterfeiting mark, a second ink, which has a chloroauric acid solution having a second concentration, is provided. Then, the second ink is applied onto the target object to form a plurality of gold nanoparticles on the surface of the anti-counterfeiting mark. Further, a tool implementing the above method is also included.

  • Patent number: 8711551
    Abstract: An electronic device includes a back shell, a support, a slide button and an elastic member. The back shell defines a first sliding slot and at least three second slots communicating with and intersecting with the first sliding slot. The support includes a connection portion connected to the back shell. The connection portion defines a through hole and includes a stop portion. The slide button is slidably connected to the back shell and includes a positioning portion. The positioning portion passes through the through hole and is operable to be selectively received in one of the second slots to enable the support to maintain different positions. The elastic member includes two ends respectively abutting against the positioning portion and the stop portion. The elastic member is configured to apply a push force to hold the positioning portion in position.

  • Patent number: 8622646
    Abstract: An electronic device includes a frame defining a slot and a first through hole, a slot cover moveably received in the slot, a latching member rotateably connected to the frame, and a torsion spring. The latching member includes a first arm and a second arm protruding therefrom and extending in opposite directions. When the latching member is at a locking position, the first arm faces the first through hole, and the second arm engages an elastic hook to retain the cover in the slot. The spring includes a first arm fixed to the first arm and a second arm fixed to the frame. The latching member is driven to rotate when the first arm is pushed by an elongated object passing through the first through hole, causing the second arm push the elastic hook to be deformed, thereby allowing the second arm to disengage from the elastic hook.

  • Publication number: 20130141355
    Abstract: An electronic device includes a touch sensitive display module. The touch sensitive display module includes a securing structure to secure a touch panel, a front frame and a display panel together. The securing structure includes an elongated securing member and double-faced adhesive tapes. The securing member includes a sidewall, and an elongated tab and an angled portion protruding from two edges of the sidewall of the securing member. The elongated tab is sandwiched between the display panel and the touch panel. The sidewall of the securing structure is sandwiched between a limiting element of the front frame and the display panel, and the limiting element of the front frame rests on the angled portion. The double-faced adhesive tape adhere the touch panel to the supporting surface of the front frame and the elongated tab, and adhere the elongated tab to the display panel.

  • Patent number: 8432682
    Abstract: An electronic device includes a housing defining a slot, a card socket, a slot cover moveably received in the slot, and an elastic piece. The card socket is capable of ejecting an electronic card out when pressed. The cover defines a through hole and an elastic hook engaging the slot to retain the cover in the slot. The elastic piece includes a base facing the first through hole, and a pair of arms connected to opposite ends of the base and abutting against the cover. The elastic piece is urged to be deformed to push the cover when the base is pushed by an object passing through the through hole, causing the hook to disengage from the slot. Then the base pushes the card to move inwardly, causing the card socket to push the card and the cover to move out of the slot in union.

  • Patent number: 8405967
    Abstract: An electronic device includes a frame defining a slot and a through hole, a slot cover moveably received in the slot, an elastic piece rotatably connected to the frame, and a torsion spring. The elastic piece includes a main body, a side arm and an extended tab defined on opposite ends of the main body. When the elastic piece is at a normal position, the side arm faces the first through hole, and the tab faces the slot. The torsion spring includes a first arm fixed to the frame and a second arm fixed to the elastic piece. The elastic piece is rotatable by insertion of an elongated object into through the through hole to push the side arm, thereby causing the tab to push the slot cover to be deformed until the hook disengages from the slot.
