Patents by Inventor Chih-Hsiang LIANG

Chih-Hsiang LIANG has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12208500
    Abstract: A control device of a power tool includes a trigger mounting bracket, a control circuit board, a control trigger, and a direction-switching button. The control circuit board is disposed on the trigger mounting bracket and has a 3D Hall sensor. The control trigger has a first magnet and is disposed on the trigger mounting bracket to approach or move away from the 3D Hall sensor along a first axis. The direction-switching button has a second magnet and is disposed on the trigger mounting bracket to approach or move away from the 3D Hall sensor along a second axis. By detecting a variation of a magnetic field generated by different magnets in the first axis and the second axis when approaching or moving away from the 3D Hall sensor through the 3D Hall sensor, the power tool could be controlled to activate and switch directions.

  • Patent number: 12122107
    Abstract: The present application relates to a composite material and a method for molding the same. Firstly, components to be pressed is disposed in a gas-isolation element, and located between two pressing plates. Next, a plate is disposed based on a location of a prepreg element of the components, and then a hot pressing step is performed. After the hot pressing step, a cooling step is performed, thereby producing the composite material of the present application. A dimension of the composite material can be easily adjusted to meet requirements of various applications.

  • Patent number: 12104316
    Abstract: A manufacturing method for an antibacterial fiber includes the following steps. A dipping step is performed to soak a conductive fiber in a solution, in which the solution includes an ionic compound, and the ionic compound includes a metal cation. An oxidation step is performed by using the conductive fiber as an anode, such that an antibacterial material produced by the solution is adhered to a surface of the conductive fiber, in which the antibacterial material includes a metal oxide.

  • Patent number: 12048916
    Abstract: The present invention relates to carbon fiber composites and a method for producing the same. By reducing specific transition metal ions with a specific concentration, the method for producing the carbon fiber composites can form nanoparticles of a transition metal on an outer surface of a titanium dioxide layer encapsulating a carbon fiber to produce the carbon fiber composites. The nanoparticles of the transition metal directionally contact the titanium dioxide layer, so that the carbon fiber composites have synergistically photocatalytic activity.
