Abstract: A device and method for reminding following distance are provided. The following distance reminding device (FDRD) adapted for a first vehicle is capable of computing a following distance between the first vehicle and a second vehicle. The FDRD comprises an image acquiring module, a reminding module, and a processing module. The image acquiring module receives a vehicle image of the second vehicle. The processing module extracts a license plate image from the vehicle image, and computes the following distance between the first vehicle and the second vehicle according to image characteristics of the license plate image. The processing module computes a safe distance according to a driving speed of the first vehicle and the image characteristics, and determines whether the following distance is more than the safe distance or not, in order to control the reminding module to correspondingly send a reminding message.

Abstract: The present invention relates to an automobile anti-collision early-warning device, which is structured from a main unit used for processing images and a plurality of camera devices. The main unit is internally provided with a holding space, within which a system board is located. The system board is configured with an image analysis unit, an early-warning message unit, a speed signal unit, a video recording unit and a sound signal unit. Moreover, a plurality of electrical members respectively extend from the system board and separately connect to the plurality of camera devices. Accordingly, when the driver activates the anti-collision early-warning device, then the anti-collision early-warning device begins to transmit images to the main unit through the camera devices, whereupon safety distances between vehicles are simultaneously calculated, thereby achieving monitoring of safe distances between front and rear vehicles at all times when driving.

Abstract: A burglarproof device is constituted by a control element, a switching element, a battery element, an electric energy transformation device, load equipment, and a charging device. When the burglarproof device is used, a supply-voltage and supply-current of the battery element is transformed into a low voltage and low current by the electric energy transformation device and through an action of the control element, such that a low voltage and low current equipment of the load equipment can continue to maintain at an original function.

Abstract: A capacity detecting circuit detects battery voltage and load current, compares the load current to the battery voltage to determine whether the voltage of the battery is sufficient, displays both the current and the relative capacity of the batteries, and cuts off power to the load if the battery voltage is too low, the current is excessive, or if the battery capacity is too low in comparison with said current.
