  • Patent number: 11936238
    Abstract: An uninterruptible power apparatus is coupled between a power grid and a load. The uninterruptible power apparatus includes a bypass path, a power conversion module, and a control module. The bypass path is coupled to the power grid through a grid terminal, and coupled to the load through a load terminal. The control module turns off a first thyristor and a second thyristor by injecting a second voltage into the load terminal during a forced commutation period. The control module calculates a magnetic flux offset amount based on an error amount between the second voltage and a voltage command, and provides a compensation command in response to the magnetic flux offset amount. The control module controls the DC/AC conversion circuit to provide a third voltage to the load terminal based on the compensation command and the voltage command.

  • Patent number: 7277097
    Abstract: A method for utilizing software to implement multiple power-up graphics in a single computer platform. The computer platform receives a power-up graphic mode and determined whether the power-up graphic mode is multiple graphic mode or general graphic mode. The computer platform then displays corresponding power-up graphics according to the power-up mode during power-up, implementing multiple power-up graphics to match IA functions or satisfy user preference.

  • Publication number: 20070150717
    Abstract: A selectable booting operation method by Basic Input Output System (BIOS) with multi-partitioned disk is provided in the present invention. The INT 19H interrupt service program in the original BIOS are slightly modified, so that when power is on the multi-partition boot selection flag being setup serves to select from the operating systems stored in different partitions of the disk, and booting time of the system is reduced accordingly. Therefore, with the present invention, users are free to choose one of the different operating systems on a single computer platform under different booting conditions upon preference without additional installation of the Boot Management Utility (BMU). Accordingly, the present invention eliminates the synchronization process that is originally performed on BMU if the operating system is being reinstalled or repeatedly installed, so as to avoid inconvenience and annoyance thereby.

  • Patent number: 5933441
    Abstract: A circuit for protecting a laser indicator is disclosed in which a current amplifying circuit composed of two transistors drives a laser light emitting diode (LED) to generate a laser light. A base of one of the two transistors connects with a protective resistor and a variable resistor. The variable resistor is used to control the magnitude of a base current of the transistor and the protective resistor is used to prevent an overrating current. A diode is further coupled to a positive power input terminal of the current amplifying circuit to prevent the circuit for protecting a laser indicator from being damaged due to being reversely connected the polarities of the power source. Through a design of such a circuit, a stable laser light-spot is achieved and the components in the circuit will not be damaged.
