  • Publication number: 20230357886
    Abstract: An exemplary embodiment of the present disclosure provides a method to extract components from a metal-containing material, forming a first multicomponent system comprising an ionic liquid and a first aqueous component, wherein the first aqueous component and the ionic liquid form an immiscible mixture when the first multicomponent system is at a temperature below a critical temperature, contacting a metal-containing material with the first multicomponent system, adjusting the temperature of the first multicomponent system above the first critical temperature to form a miscible mixture with the ionic liquid and the first aqueous component, reverting the temperature of the first multicomponent system below the critical temperature to form an immiscible mixture with the ionic liquid and the first aqueous component, and isolating the ionic liquid from the first aqueous component and the metal-containing material, wherein the ionic liquid comprises one or more metals from the metal-containing material.

  • Publication number: 20130083437
    Abstract: An ESD elimination device includes an ESD elimination circuit connected between a power line and a ground line and an ESD detection circuit. The ESD detection circuit includes a switch unit and a resistor, the switch unit and the resistor are electrically connected between the power line and the ground line. The switch unit is turned on when an ESD event occurs in the power line, a detecting voltage is generated across the resistor when the switch unit is turned on, the detecting voltage is used for triggering the ESD elimination circuit to eliminate the ESD surge current caused by the ESD event.

  • Publication number: 20090327307
    Abstract: A personal routine system that automatically traces and links a users' time, locations and activities. The person routine system includes a position recording unit for recording the user's location information, a routine tracking system having a first mapping module for matching data and files the data with the user's time and location information, and a service platform. The routine tracking system also provides a browse function and a search function for the matched records and transfers them to the service platform. The service platform stores the records transmitted from a second network interface into a second storage unit and uses a user interface to display the records stored in the second storage unit and further provides the browse and search functions.

  • Publication number: 20070252615
    Abstract: A logic-keeping apparatus including a logic judgment unit and a noise-event detection unit is disclosed. When the level at the input terminal of the logic judgment unit is larger than a first level, the output terminal thereof outputs a first logic state; when the level at the input terminal is smaller than a second level, the output terminal thereof outputs a second logic state; when the level at the input terminal is between the first level and the second level, the output terminal thereof keeps the previous logic state. The noise-event detection unit is for detecting whether a noise-event occurs (for example, an ESD event). Wherein, when a noise-even occurs in the system, the noise-event detection unit keeps the level at the input terminal of the logic judgment unit between the first level and the second level.

  • Publication number: 20070247183
    Abstract: A logic-latching apparatus includes a noise-event detection unit, a combinational logic unit and a latch unit. The noise-event detection unit is used for detecting whether or not a noise-event occurs (for example, an ESD). The latch unit is coupled with the noise-event detection unit and the combinational logic unit for latching the state of the combinational logic unit. When the output of the noise-event detection unit indicates that a noise-event occurs, the latch unit provides the input terminal of the combinational logic unit with a corresponding input signal according to the latched state of the combinational logic unit inside the latch unit to prevent the state of the combinational logic unit from being affected by the noise-event.
