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: A novel reversible ratchet wrench may include a wrench body, a control member, a ratchet member and a rotating member, wherein the control member has a restricting slot and two stopper planes, and a deep hole for placing the spring. The control member is placed into the round hole of the wrench body by the half cylindrical body and connects with the ratchet member which is placed into the arc-shaped ratchet slot, thereby resulting in a secure relative positioning between the control member and the ratchet member. The novel reversible ratchet wrench allows convenient switch between directions of the rotational movement of the wrench body and the structural design effectively prevents the spring from ejecting from the deep hole of the control member or getting stuck by restricting the movement space of the spring. Furthermore, this structural design improves the smoothness of switching operation of the ratchet wrench.

Abstract: A hinge includes a connecting member, a first shaft member, a pivoting member, at least one shock absorber and a restoring unit. The first shaft member extends rotatably through the connecting member. The pivoting member is connected co-rotatably to the first shaft member, and is connected to the object. The pivoting member has at least one limiting surface facing the object. The shock absorber is disposed between the limiting surface of the pivoting member and the object for preventing collision between the pivoting member and the object. The restoring unit is disposed in the connecting member for driving rotation of the first shaft member toward a neutral position.
