Abstract: A mobile phone has an encryption module, a decryption module, an antenna, a microphone, a speaker, a main memory, and a memory connector for connecting to an expansion memory. When the expansion memory connects to the memory connector to store a document received from the mobile phone, the encryption module first generates a crypto-key and then encrypts the document into a ciphered document by utilizing the crypto-key. The ciphered document is stored in the expansion memory, and crypto-key is restricted from being stored in the main memory.

Abstract: The invention relates to a method of carrying out a safe remote electronic signing by a cellular phone coupled to a computer having a browser for setting conditions for accessing the Internet, the computer being operated to perform the steps of registering for obtaining an authorized browsing driver from a server based on the conditions; installing the browsing driver in the cellular phone; and when the cellular phone is activated to access the Internet for remote signing of an electronic document, selecting a safety level by running the browsing driver in response to the selected safety level, adding a corresponding password in the document, and sending the document over the Internet in a form of encryption for transmission on an authorized network channel.

Abstract: A method of downloading application programs on the editing system platform of an electronic communication apparatus, includes the step of connecting an electronic communication apparatus to the Internet, the step of driving an editing system of a processor of the electronic communication apparatus to define a total area from a memory thereof for use by the application programs to be downloaded from the Internet, for enabling the application programs to be stored in any address within the total area, the step of driving the editing system to directly correct the operating instruction of direct address searching to the correct address when downloading an application program from the Internet and then to search the address after address correction, and the step of using a software interrupt (SWI) to alternate the operating instruction of indirect address searching so as to obtain the desired correct address for the editing system for further indirect address searching operation.

Abstract: A method of data access by simulating an external device to be a hard disk drive, the method enables an external device to proceed with data exchange directly with a computer. The data access method includes the following steps: firstly, the first operation system of a host detects an external device, and requests for a USB device describer from the external device. Next, the connection relationship between the host and the external device is set up in accordance with the USB device describer. An operation command is sent from the first operation system of the host to the external device, and the second operation system in the external device proceeds with data operation according to the operation command, and sends a completion message back to the host.

Abstract: A method for dialing an Internet protocol phone via a GPRS network is disclosed. First, a calling side unit issues a request signal for communication to a receiving side unit, wherein the request signal for communication includes a calling side IP address and a calling side communication port. Then, the receiving side user receives the request signal for communication and sends back a responding user datagram protocol (UDP) packet to the calling side unit, according to the calling side communication port, in which the responded UDP packet includes the calling side IP address of the calling side unit. Next, the calling side unit receives the UDP packet from the calling side IP communication port, and begins to transmit and receive the UDP packet carrying the voice digital data with the receiving side unit, so as to perform the communication via the Internet protocol phone. The present invention allows the user to easily dial the Internet protocol phone with a reduction of the communication cost.

Abstract: The invention relates to a separating system with hollow fiber membranes and an operating method. A dual backwash loop which is a pipeline connecting a top port of the said membrane assembly to a cleaning pump through a first branch and a second branch. The first branch is designed to fill a small amount of cleaning liquid into the said membrane assembly; and the second branch is designed to fill a relatively large amount of cleaning liquid in order to clean the membrane adequately. The said system operates in the following procedures: operation status, cleaning status 1, cleaning status 2, drain status, returning to the operation status. The technology of the present invention may be used to enhance the cleaning effect to the membrane system, further save water for the cleaning process, shorten the cleaning time, thus benefiting the continuous large scale industrial production and having higher efficiency.

Abstract: A phone book intelligent dialing method used in mobile phones. The method uses a country code table and area code table to analyze the phone number entered so that the phone number is a complete one, containing the country code and the area code, when being stored to the phone book. By defining related symbol tags for identification in the phone book (such as the country codes, area codes, pager numbers, and usual phone numbers), the data type of the phone number to be dialed can be analyzed to determine the exact phone number. Since the user does not need to manually enter the country codes, extension numbers, or pager numbers using the disclose method, the present invention is simple and does not make mistakes.
