Dock for portable devices

Abstract

Another embodiment of the invention provides a dock for connecting to a portable device. The dock includes a charging module, a backup program and a controller. The controller controls the dock to operate at a first mode or a second mode. When the dock operates at the first mode, the controller controls the charging module to charge the portable device, and when the dock operates at the second mode, the controller controls the charging module to charge the portable device and the backup program is executed to backup data of the portable device simultaneously.

1 . A dock for connecting to a portable device, comprising:
 a charging module;   a backup program; and   a controller to control the dock to operate at a first mode or a second mode, wherein when the dock operates at the first mode, the controller controls the charging module to charge the portable device, and when the dock operates at the second mode, the controller controls the charging module to charge the portable device and the backup program is executed to backup data of the portable device simultaneously.   
     
     
         2 . The dock as claimed in  claim 1 , wherein the charging module connects to an AC voltage source and transforms an AC voltage into a DC voltage for charging the portable device. 
     
     
         3 . The dock as claimed in  claim 1 , wherein the dock further comprises a storage medium and the data of the portable device is backed up in the storage medium. 
     
     
         4 . The dock as claimed in  claim 1 , wherein the dock backs up the data of the portable device to a backup server via an internet network. 
     
     
         5 . The dock as claimed in  claim 5 , wherein when the backup program is executed, the backup program executes the following steps:
 establishing a first transmission path, by the controller, between the dock and the backup server, wherein the first transmission path represents that the dock directly backs up data of the portable device to the backup server;   establishing a second transmission path, by the controller, between the dock and the backup server, wherein the second transmission path represents that the dock backs up data of the portable device to the backup server via a third party;   establishing a third transmission path, by the controller, between the dock and the backup server, wherein the third transmission path represents that the dock backs up data of the portable device to the backup server via a router or a wireless access point; and   selecting one of the first transmission path, the second transmission path and the third transmission path according to a select signal.   
     
     
         6 . The dock as claimed in  claim 1 , wherein when the dock operates at the second mode, the control of the portable device is transferred to the dock. 
     
     
         7 . The dock as claimed in  claim 1 , wherein when the dock operates at the second mode, the backup program is downloaded to the portable device and executed by a processor of the portable device. 
     
     
         8 . The dock as claimed in  claim 7 , wherein the controller is controlled by the processor of the portable device. 
     
     
         9 . The dock as claimed in  claim 1 , further comprising a communication interface for connecting to an internet network via a wired/wireless connection mechanism. 
     
     
         10 . An electronic system, comprising:
 a portable device; and   a dock for physically connecting to the portable device, wherein the dock comprises:
 a charging module; 
 a backup program; and 
 a controller to control the dock to operate at a first mode or a second mode, wherein when the dock operates at the first mode, the controller controls the charging module to charge the portable device, and when the dock operates at the second mode, the controller controls the charging module to charge the portable device and the backup program is executed to backup data of the portable device simultaneously. 
   
     
     
         11 . The electronic system as claimed in  claim 10 , wherein when the dock operates at the second mode, the backup program is downloaded to the portable device and executed by a processor of the portable device, and the controller is controlled by the processor of the portable device 
     
     
         12 . The electronic system as claimed in  claim 10 , wherein when the dock operates at the second mode, the control of the portable device is transferred to the dock. 
     
     
         13 . The electronic system as claimed in  claim 10 , wherein the charging module connects to an AC voltage source and transforms an AC voltage into a DC voltage for charging the portable device. 
     
     
         14 . The electronic system as claimed in  claim 10 , wherein the dock further comprises a storage medium and the data of the portable device is backed up in the storage medium. 
     
     
         15 . The electronic system as claimed in  claim 10 , wherein the dock backs up the data of the portable device to a backup server via an internet network. 
     
     
         16 . The electronic system as claimed in  claim 15 , wherein when the backup program is executed, the backup program executes the following steps:
 establishing a first transmission path, by the controller, between the dock and the backup server, wherein the first transmission path represents that the dock directly backs up data of the portable device to the backup server;   establishing a second transmission path, by the controller, between the dock and the backup server, wherein the second transmission path represents that the dock backs up data of the portable device to the backup server via a third party;   establishing a third transmission path, by the controller, between the dock and the backup server, wherein the third transmission path represents that the dock backs up data of the portable device to the backup server via a router or a wireless access point; and   selecting one of the first transmission path, the second transmission path and the third transmission path according to a select signal.   
     
     
         17 . The electronic system as claimed in  claim 16 , wherein the select signal is generated according to a network link quality or a transmission speed of the first transmission path, the second transmission path and the third transmission path. 
     
     
         18 . An operation method of a dock, comprising:
 determining whether a log file exists in a portable device;   backing up files from the portable device to a backup server according to the log file when the log file exists;   determining to charge the portable device or not according to the log file; and   when the log file does not exist, only charging the portable device.
