Abstract: A memory device including a base semiconductor die, conductive terminals, memory dies, an insulating encapsulation and a buffer cap is provided. The conductive terminals are disposed on a first surface of the base semiconductor die. The memory dies are stacked over a second surface of the base semiconductor die, and the second surface of the base semiconductor die is opposite to the first surface of the base semiconductor die. The insulating encapsulation is disposed on the second surface of the base semiconductor die and laterally encapsulates the memory dies. The buffer cap covers the first surface of the base semiconductor die, sidewalls of the base semiconductor die and sidewalls of the insulating encapsulation. A package structure including the above- mentioned memory device is also provided.

Abstract: An ultra-wideband assisted precise positioning system and an ultra-wideband assisted precise positioning method are provided. The method includes: arranging a plurality of device nodes in a target area; configuring a central control device node to communicatively connect to the device nodes; configuring the device nodes to perform a positioning process to obtain measured distances and positioning positions to be corrected; and configuring a central control processor to execute a positioning algorithm. The positioning algorithm includes: obtaining the measured distances and the positioning positions to be corrected; for each of the positioning positions to be corrected, performing a center-of-gravity weighting processing on neighboring points for obtaining initial guess positions; and obtaining the initial guess positions to input to an optimizer and optimize an objective function, and finding corrected positions with relatively smallest errors.
