A blind spot detection system with speed detection function and device and method thereof are provided. The system is disposed on the rear portion of the vehicle, and includes a signal transceiving module and a central processing unit. The central processing unit includes a speed calculation module and an object detection module. The device includes a main body in which the signal transceiving module is disposed. A first signal is sent toward a detection area behind the vehicle for acquiring a second signal for blind spot detection. By calculation based on the second signal, a third signal is acquired for identifying the static and moving objects, and the relative speed between the vehicle and the static object is determined as the speed of the vehicle. Therefore, the blind spot detection system has a speed detection function.

An integrated contactless signal transfer apparatus makes use of the rule of filter design to transfer signal from a chip to the transmission lines of a PCB. The integrated contactless signal transfer apparatus includes a substrate, a chip disposed on the substrate, a first resonator unit disposed on the chip for receiving a first signal with a first frequency generated from the chip, a PCB positioned at a distance opposite to the substrate, and a second resonator unit disposed on the PCB. The first signal passes through the first resonator unit to generate a contactless coupling between the first and second resonator units, so the second resonator unit generates a second signal. The second signal has a second frequency substantially equal to the first frequency.
