Abstract: A method and an electronic device of updating and testing multiple embedded controllers (ECs) are provided. First, in the electronic device, a basic input output system (BIOS) executes an updating software to read an embedded-controller read-only file (ECROF) in an external read-only memory (ROM). A first embedded controller (first EC) writes the ECROF from the external ROM into the first EC. The first EC uses the ECROF to update a first firmware of the first EC. Then, the first EC updates a second firmware of a second embedded controller (second EC) with the ECROF. Next, the first EC or another hardware device compares the first summary information stored in the first EC and the second summary information of the updated second EC. When the first summary information and the second summary information are different, the first EC or the hardware device generates a warning message.

Abstract: A baby walker is introduced herein. The baby walker includes a base and a pair of shoulder straps. The base is made by flexible materials such as plastics, or the similar materials. In one exemplary embodiment, the base of the baby walker may be packaged in a deflated form, and may be filled with air to form a shape as desired for an operation mode. The baby walker further includes a pair of shoulder straps which are firmly and fixedly attached in a peripheral upper side of the base. When the baby is placed in a central cavity of the base, the pair of the shoulder straps can be placed alongside the two shoulders of the baby. When the baby wears the baby walker and stands up, the whole baby walker is lifted up for a height above the ground level.
