Abstract: A method for automatically designing a buffer packing size and a computer accessible storage media to store program thereof are provided. First, a buffer thickness of a buffer material is calculated, and a buffer area for a surface of the object receiving an impact is calculated according to a weight of an object and a static stress of the buffer material. Next, a suitable buffer packing size is automatically calculated according to the buffer thickness and the buffer area.

Abstract: The present invention is to provide a method for protecting data applied to an electronic communication device, which enables the electronic communication device to receive a wireless signal containing a data output instruction transmitted by a user of the electronic communication device when the electronic communication device is stolen or lost, output a plurality of preset protected data stored in the electronic communication device to an external storage device, and delete the preset protected data from the electronic communication device so that the preset protected data no more exists in the electronic communication device and can't be used by others who picked up or stole the electronic communication device.
