  • Patent number: 10936029
    Abstract: A method for cooling a heat source by liquefied gas is provided, wherein the heat source is cooled by filling a liquefied gas into a chamber close to the heat source, and the heat source is located in an electronic device. The temperature of the heat source is detected, and the liquefied gas is filled into the chamber via an inlet valve to absorb heat generated by the heat source when the temperature of the heat source rises to a first value. Specifically, an exhaust valve that communicates with the chamber is opened when the temperature of the heat source decreases and then rises to a second value or the pressure inside the chamber reaches a critical value, so that the liquefied gas in the chamber can be vaporized and discharged through the exhaust valve to an atmospheric environment.

  • Patent number: 9536683
    Abstract: A touch module is provided, including a hollow frame, a positioning member, and a touch unit. The positioning member includes a main body, an extending portion, and a U-shape structure. The extending portion is connected to the main body and fixed to the frame. The U-shape structure includes a contact portion and a pair of flexible arms. The flexible arms are connected to the main body, wherein the U-shape structure and the main body form a gap therebetween. The contact portion and the extending portion are disposed on opposite sides of the main body, wherein the contact portion is disposed between the two flexible arms. The touch unit is connected to the main body and forms a protrusion, wherein when a force is applied to the touch unit, the protrusion contacts the contact portion.

  • Patent number: 9367089
    Abstract: An electronic apparatus combined with a magnetic attraction force includes a first body and a second body. The first body includes at least one first magnetic element, and the second body includes at least one receiving groove, at least one moving assembly, and at least one assistant magnetic element. Each moving assembly is movably disposed in each receiving groove, and each moving assembly includes a second magnetic element. Each assistant magnetic element is fixed in the receiving groove, and the magnetic attraction force between the assistant magnetic element and the second magnetic element is smaller than that between the first magnetic element and the second magnetic element. When the second body is combined with the first body, each second magnetic element is attracted by each first magnetic element, such that each moving assembly is driven to move toward the first body.
