  • Publication number: 20240152193
    Abstract: The invention provides a power supply including at least one power output port, at least one status alert component, and at least one output port status monitoring module. The status alert component generates at least one visual prompt based on an alert signal. The output port status monitoring module includes at least one temperature sensor adjacent to the power output port, a microcontroller connected to the temperature sensor and sensing an output current from the power output port, and a reset signal generator connected to the microcontroller. The microcontroller comprises at least one port status alert condition that takes a temperature and the output current of the power output port as decision factors. The microcontroller outputs the alert signal to the status alert component when the port status alert condition is met and maintains the status until a reset signal provided by the reset signal generator is received.

  • Patent number: 7391006
    Abstract: A fingerprint scanning device and an electronic device with a fingerprint scanning function are proposed. The fingerprint scanning device has a contact image sensing module, a signal conversion controller, a module controller and an interface controller. The contact image sensing module captures a fingerprint image. The signal conversion controller converts this analog fingerprint image to a digital signal. The module controller controls the contact image sensing module and the signal conversion module. The interface controller transmits the digital signal to a controller in an electronic device. The contact image sensing module is used to lower the cost and lengthen the lifetime of use of the fingerprint scanning device, and to make the captured fingerprint image clearer. The interface controller is connected to the signal conversion module and the module controller to make the digital signal transmitted by the signal conversion controller more easily accessible.

  • Patent number: 6617392
    Abstract: The present invention provides the molding composition of siloxane, which is capable of extending mold lifetime where inhibitors alkene or acetylene polymerization are mixed in the molds composed of siloxane. The inhibitors can effectively inhibit the release of alkene or acetylene when a resin containing an alkene or acetylene is poured into the molds which extends lifetime of molds composed of siloxane. The inhibitors are compounds containing primarily sulfur, wherein sulfur is the most effective.
