  • Patent number: 11964881
    Abstract: A method for making iridium oxide nanoparticles includes dissolving an iridium salt to obtain a salt-containing solution, mixing a complexing agent with the salt-containing solution to obtain a blend solution, and adding an oxidating agent to the blend solution to obtain a product mixture. A molar ratio of a complexing compound of the complexing agent to the iridium salt is controlled in a predetermined range so as to permit the product mixture to include iridium oxide nanoparticles.

  • Patent number: 11923794
    Abstract: A motor control apparatus receives a DC power source through a DC terminal and is coupled to a motor. The motor control apparatus includes a brake, an inverter, and a controller. The brake is coupled to the inverter. The brake includes an energy-consuming component and a switch component. The controller controls the inverter to convert the DC power source to drive the motor. When the controller determines that the DC power source is interrupted, the controller stops controlling the inverter, and the switch component is self-driven turned on so that a back electromotive force generated by the motor is consumed through the energy-consuming component.

  • Publication number: 20200134149
    Abstract: A login mechanism for an operating system, including: a computer device, loaded with a computer operating system; and a mobile device, capable of sending a login password for the computer operating system, and capable of authenticating a human biometric feature. In the login mechanism of the present invention, the login password for the computer operating system is stored on the mobile device. When a user logs in to the computer operating system, the mobile device authenticates a biometric feature. After authentication succeeds, the mobile device transfers the login password to the computer device, so as to log in to the computer operating system. A user does not need to enter a login password, and two-factor authentication including login password authentication and biometric feature authentication is used to protect the security of login to the computer operating system.
