The invention provides a ramp speed limiting value prompting device and method and relates to the field of traffic safety. According to the invention, the device and the method comprises steps of based on a current environment image or the current travel speed, or based on the current environment image and a road type, recognizing whether the acquired current environment image includes a ramp speed limiting identifier; then, when the current environment image includes the ramp speed limiting identifier, according to the current environment image or the current position information or the travel state information, judging whether a vehicle enters a ramp preparation state; and when the vehicle enters the ramp preparation state, generating a speed limiting value prompt corresponding to the ramp speed limiting identifier, thereby achieving precise determination of the ramp speed limiting identifier. According to the invention, through the precisely determined ramp speed limiting identifier, it is determined that the vehicle enters the ramp preparation state, and at this moment, a speed limiting value prompt corresponding to the ramp speed limiting identifier is generated, so precise speed limiting value prompting is achieved when the vehicle travels on the ramp, error judgment will not be caused and experience of the driver is improved.

A method for increasing a signal to noise ratio of a capacitive touch device and a capacitive touch device and a touch panel using the same are provided. The capacitive touch device includes a first sensing electrode, a second sensing electrode, a touch detector, a resonant inductor and a detection signal output circuit. An output terminal of the detection signal output circuit outputs a detection signal, such that the resonant inductor and an equivalent capacitor of the first sensing electrode are resonant, and the first sensing electrode receives a resonant sinusoidal wave. When an electric field signal detected by the detecting terminal of the touch detector is smaller than a preset value, it is determined that the capacitive touch device is touched.

The invention provides a double-click processing method and a slaved electronic device. A misjudgment of double-click operation can be avoided when a main control electronic device is connected with multiple slaved electronic devices. The double-click processing method comprises the steps that a first parameter value corresponding to first-time click operation is received and recorded; a second parameter value corresponding to second-time click operation is received and recorded; whether a first difference value of the second parameter value and the first parameter value meets a preset double-click threshold or not is judged; when it is judged that the first difference value meets the preset double-click threshold, a defined double-click parameter value is sent to the main control electronic device, a defined double-click difference value corresponding to the defined double-click parameter value is located within a system double-click threshold, the system double-click threshold is the double-click condition arranged in the main control electronic device, and therefore the situation that the slaved electronic device conducts double-click operation can be determined by the main control electronic device according to the defined double-click parameter value and the system double-click threshold.

The invention discloses a method for identifying true and false precious metal ornaments. Appropriate laser pulse energy and defocusing distance are selected according to the material and thickness of a sample; precious metal ornaments are corroded by pulse laser in single points; the primary treatment procedure of the sample is simplified; the corroded material of the metal ornaments is detected by using an inductively coupled plasma source mass spectrometer; a time-resolved figure of an isotope is detected by collecting respective elements; the true and false precious metal ornaments can be known by analyzing the time-solved figure; and the purity of the precious metal can be accurately obtained by standardless analysis. The method has the advantages that the time required for the overall corrosion and signal collection processes is 1-2 minutes; the detection speed is high; in addition, the laser strength is not reduced due to increase of corrosion depth; misjudgment due to the fact that the sample cannot be fully corroded due to over-thickness is avoided; the method is not limited by coating or plating thickness; the identification accuracy is high; the corrosion diameter is 30-80 microns; and the appearance of a solid sample is in a good shape at the macro level.
