Abstract: A radar self-calibration device and method are disclosed. The device includes an antenna transceiver module and a processor. The antenna transceiver module has a detection range. The processor is coupled with the antenna transceiver module for obtaining a relative velocity and an angle of the object with respect to the antenna transceiver module in a period of time. The relative angle is the angle included between the object and the driving direction of the vehicle body with respect to the vehicle body. The processor determines if the relative angle is equal to an ideal angle according to a detection model. The detection condition of the detection model includes that when the relative velocity is 0, the ideal angle is 90 degrees. Thus, the present invention assures the correctness of the detected angle through the detection model. When the detected angle is incorrect, the error is promptly calibrated.

The first radar module gives a first radar signal that defines a first detection range. The second radar module gives a second radar signal that defines a second detection range. The first radar module and the second radar module give a first radar signal and a second radar signal toward each other, respectively, so that the first detection range and the second detection range fully cover the lateral of the vehicle, thereby providing full detection without any dead spaces.

Abstract: A method for manufacturing an electronic device casing having a coupling structure is provided. The electronic device casing is made of a casing material including a supportive substrate and a first thermoplastic substrate. A preliminary connecting section is formed on the first thermoplastic substrate by a hot-pressing molding process, and a molding plastic material is injected onto the preliminary connecting section by an in-mold injection process. After being cooled, the molding plastic material engages with the preliminary connecting section to form a secondary connecting section for a coupling element to couple with. Thus, the coupling structure of the electronic device casing can be directly formed during a manufacturing process without any additional procedures, thereby overall manufacturing time and costs are reduced.
