A copper-palladium-loaded mesoporous silicon carbide-based catalyst, a preparation method, and an application thereof are provided. First, a mesoporous silicon carbide material is prepared by using mesoporous silica as a hard template; subsequently, the mesoporous silicon carbide material is mixed with a copper-palladium precursor mixed solution, and dried after the solvent is completely volatilized. The dried powder is successively subjected to calcination with Nand reduction with Hto finally obtain the copper-palladium-loaded mesoporous silicon carbide-based catalyst. The catalyst is made into an electrode, and the nitrate in water body is catalytically reduced by electrochemical method. The preparation method of the catalyst of the present invention is simple. The catalyst can realize high-efficiency catalytic denitrification at a low metal loading amount, with high selectivity of nitrogen. Moreover, the catalyst has the advantages of high activity, good stability, wide application range and low cost.

A WI-FI parameter transmitting device can transmit a WI-FI parameter in the form of a broadcast signal, and includes an encryption module, a configuration module, a modulation module, and a play module. The encryption module obtains and encrypts the WI-FI parameter and the configuration module configures an encrypted WI-FI parameter and authorization information to generate WI-FI configuration information. The modulation module modulates the WI-FI configuration information with a carrier signal to generate a PCM signal and the play module plays the PCM signal in at least one predetermined frequency. A WI-FI parameter transmitting method and a WI-FI parameter receiving device and method are further provided.

A tracking detection and alarm method which is applied to a navigation device use a number of positioning data points retrieved from a navigation module of the navigation device. A number of deflections and a number of average speeds that correspond to the position data points are calculated and generated. A number of maximum deflections are calculated and generated according to the average speeds. When a deflection of a positioning data point is greater than a maximum safe deflection thereof, one is added to a frequency of unsafe driving instances. When the frequency of unsafe driving instances is greater than a preset threshold value, an unsafe driving alarm is activated.
