Abstract: An electronic device and method for setting an operating interface according to information downloaded via network are disclosed. The electronic device includes a network transmission module for downloading at least one operating interface reference message by network transmission, a display module for displaying the operating interface, and a control unit coupled to the network transmission module and the display module for controlling the display module to display the corresponding operating interface according to the at least one operating interface reference downloaded by the network transmission module. Such operating interface can meet requirements for the diversity and customization of electronic products and has personal characters.

Abstract: The present disclosure discloses a navigation device and a navigation method. The navigation method includes a satellite signal receiving module of the navigation device for receiving a positioning signal, a control unit of the navigation device for controlling a display module to display a navigation map on a map region according to the positioning signal, and the control unit of the navigation device for controlling a prompt region to present prompt information with different light effects according to traffic information. The prompt region is located outside the map region. Therefore, it is unnecessary for the user to further pay too much cognitive attention on understanding or referring to the navigation images and instructions, so the driving safety can be ensured.

Abstract: In an electric contact material of silver matrix capable of resisting arc erosion and containing no cadmium-composite, an Ag—(SnO2+In2O3) composite containing 9˜11% of (SnO2+In2O3) or an Ag—Cu oxide, composite containing 15˜25% of Cu oxide is used. The electrical contact material has a contact resistance of 5˜60 milliohms (mohm) and an arc erosion resistance capability up to 2*103˜10*103 times provided that the Vickers hardness (Hv) of the material is 100˜150, the measured current is 1˜5 amperes, and the measured voltage is 10˜20 volts. Two electrical contacts maintain an arc erosion resisting capability at the condition of a low contact resistance when the electrical contact material is formed on a surface of a metal substrate of an electric connector.

Abstract: A reversible ratchet wrench includes a drive shank having a support base, a shell pivotally mounted on the support base, a ratchet wheel mounted in the shell and having a plurality of ratchet teeth, a pawl member having a first side provided with a driven face that is driven by the support base to move the pawl member relative to the ratchet wheel and a second side provided with a toothed engaging face meshing with the ratchet teeth. Thus, the user only needs to hold the support base to shake and drive the shell to pivot relative to the support base by the weight of the shell and the ratchet wheel so as to change the operation direction of the ratchet wheel, so that the user can change the operation direction of the ratchet wheel easily and quickly.

Abstract: A reversible ratchet wrench includes a drive shank having a support base, an open shell pivotally mounted on the support base, a ratchet wheel having a plurality of ratchet teeth, a pawl member having a sliding face slidably mounted on the support base and a toothed engaging face meshing with the ratchet teeth, and a cover to cover the ratchet wheel, the pawl member and the support base of the drive shank. The shell is pivoted relative to the support base to change the operation direction of the ratchet wheel. Thus, the user only needs to hold and pivot the shell relative to the support base to change the operation direction of the ratchet wheel, so that the user can change the operation direction of the ratchet wheel easily and quickly.
