Abstract: An electronic package module and a method for fabrication of the same are provided. The electronic package module has the circuit substrate with the flat surface and the electronic component located on the circuit substrate. The electronic component includes the input end located on the flat surface of the circuit substrate and electrically connected to the circuit substrate. The electronic component includes the main part located on the input end and the ground end located on the main part. The input end and the ground end are located on two opposite sides of the main part separately and are located between the ground end and the circuit substrate. The input end, the main part and the ground end are arranged along the normal direction of the flat surface.

Abstract: An ultra wideband (UWB) dynamic positioning method and a system thereof are provided. A target UWB device detecting step includes driving a host UWB device to detect whether a target UWB device or at least one first-order seeking UWB device is around the host UWB device, and then a detecting result is generated. A host UWB device operation deciding step includes deciding an operating mode of the host UWB device according to the detecting result. When the target UWB device is around the host UWB device, the operating mode includes calculating a moving direction from the host UWB device to the target UWB device. When there is the first-order seeking UWB device around the host UWB device without the target UWB device, the operating mode includes switching on the first-order seeking UWB device to enter a seeking mode.
