Abstract: A method and a system for transmitting data and an electronic apparatus using the method are provided. The electronic apparatus is detachably coupled to an external apparatus. When the electronic apparatus performs data transmission with the external apparatus via a first transmission path, whether a state change signal is generated is checked. After the state change signal is generated, the follow-up data to be transmitted to the external apparatus is stored temporarily in a virtual storage interface. And, after a second transmission path is established between the electronic apparatus and the external apparatus, the data stored temporarily in the virtual storage interface is transmitted to the external apparatus via the second transmission path, so as to continue the data transmission with the external apparatus.

Abstract: A fingerprint method for access control includes the steps of: providing an application server (20) for controlling access of different users; providing a database (40) connected to the application server for storing original fingerprint data of each user; scanning a fingerprint of a user through a handheld device (10), and obtaining fingerprint data of the scanned fingerprint; establishing a wireless communication channel between the handheld device and the application server, and transmitting the fingerprint data to the application server through the wireless communication channel; receiving the fingerprint data from the handheld device by the application server; determining whether the fingerprint data is the same as the original fingerprint data of the user in the database; and the user to access an access control device (30) connected to the application server if the fingerprint data is the same as the original fingerprint data stored in the database.

Abstract: A portable electronic device includes a random access memory, a non-volatile random access memory, a detecting unit, and a processing unit. The detecting unit is configured to detect an acceleration of the portable electronic device. The processing unit is configured to compare a value of the acceleration of the portable electronic device with a predetermined parameter. If the value of the acceleration is greater or equal to the predetermined parameter, data is copied from the random access memory to the non-volatile random access memory.

Abstract: A system and method for associating functions of an electronic device comprises setting one or more associated functions and storing the associated functions onto a storage system of the electronic device, searching the storage system and determining if there are functions associated with a selected function, and displaying sub-options of the selected function as well as the functions associated with the selected function.

Abstract: A portable electronic device (10) includes a data cable (105) and a housing (101). The data cable is configured to receive or transfer data. The housing includes a receiving portion (103) formed therein; the receiving portion is configured for receiving the data cable.
