    摘要: A measurement circuit includes a switch unit with a number of keys selectively pressed to output different resistance regulating signals. A resistance setting circuit receives the resistance regulating signals and connects different resistances to a voltage circuit and a current circuit. The voltage circuit outputs different voltages. The current voltage receives a voltage from the voltage circuit and outputs a current to a capacitor. A detecting circuit measures a temperature of the capacitor and outputs the temperature to the resistance setting circuit. The resistance setting circuit compares the received temperature with a preset temperature. If the received temperature is equal to or greater than the preset temperature, the resistance setting circuit outputs short-circuit information of the capacitor. If the received temperature is less than the preset temperature, the resistance setting circuit outputs normal information of the capacitor. A display unit displays the information of the capacitor.

When the edge connector is inserted into a second DIMM socket of a motherboard and the motherboard is powered on, the resistor samples first current, and converts the first current into a first voltage. The differential amplifier circuit amplifiers the first current to a second current. The voltage dividing circuit divides the first voltage, and outputs a second voltage. The controller converts the second current into a third current, converts the second voltage into a third voltage, and calculates a power according to the third current and the third voltage.

    摘要: A glass-ceramic cooking apparatus and a method relating to temperature limiting control of the glass heating area for preventing cooking oil ignition is disclosed. The apparatus comprises at least one glass surface, at least one heat source under the glass to create a heating area on the glass, one temperature sensor and one control unit for each heat source, wherein the sensor measures the temperature on the underside the glass heating area, and the control unit is electrically connected with the heat source, compares the measured glass temperature with predetermined upper and lower temperature limits that are based on a corresponding relationship between the heating area temperature and the cooking oil temperature within the cooking vessel, and then reduces or increases the output power of the heating source, so that the maximum temperature of the cooking oil in the cooking vessel can be limited in a range that is below the cooking oil ignition point while a minimum temperature can still be maintained for a desired cooking performance.

    摘要: A portable electronic device includes a first body and a second body. The first body includes a casing, a supporter, a first magnetic component and a torsion component. The casing includes an accommodating trench and a first trench communicated with the accommodating trench. A first lateral of the supporter is pivoted to the casing via the torsion component, and a second lateral of the supporter includes a notch. The magnetic component is slidably disposed in the first trench. The second body is pivoted to the first body and includes a second magnetic component. When the supporter is located in the accommodating trench and the first magnetic component extends into the notch, the supporter is positioned inside the accommodating trench by the first magnetic component, and the torsion component stores elastic potential energy. When the second body is rotated close to the first body, the first magnetic component exits the notch due to a magnetic repulsive force of the second magnetic component, and the torsion component releases the elastic potential energy so that the second lateral of the supporter is rotated out to support the second body.
