Abstract: A method for automatically updating a ciphering key used in a network system. The network system has a server, an access point connected to the server, a station, and a counting module. The access point is used to transmit data received from the server via wireless transmission, and receive data transmitted via wireless transmission. The access point uses a first ciphering key to encrypt transmission data. The method includes: detonating the counting module to start counting the time; randomly generating a second ciphering key if the time counted by the counting module conforms to a predetermined time; the access point transmitting the second ciphering key to the station so as to update the first ciphering key stored in the station with the second ciphering key; and using the second ciphering key to encrypt data transmitted between the access point and the station.

Abstract: A changeable keyboard arrangement includes a database established in the memory of an electronic device, with a minimum of one or more keyboard layout code-page tables stored in the database such that the user can change to a different keyboard layout on the electronic device, and after selecting the key configuration of the keyboard to be changed from a keyboard layout set-up menu, the CPU of the electronic device reads numbers from the key code-page table stored beforehand in the memory; as such, when the user changes a keyboard layout and presses various keys, the CPU searches for the corresponding numbers in the code-page tables based on the first signal issued by the contacts of the keys within a unit interval and then executes the relevant processing.

Abstract: The invention is a method for communication apparatus in utilizing global positioning system to proceed time switch, wherein a global positioning system and a communication apparatus are integrated as a whole, and in one memory of said communication apparatus preset with a database of various time zone worldwide including a comparison table of the time differences between each said time zone and the longitude and latitude coordinates covered by each said time zone, and said communication apparatus utilizes said global positioning system to judge the longitude and latitude coordinates of residence and location, and utilize said comparison table according to the longitude and latitude coordinates of residence and location for searching the corresponding time differences therebetween, and renew the preset time to local time according to said time differences.

Abstract: In a cellular phone having a memory with a data base for storing a time conversion table regarding time of one place in the world belonging to a first telephone system and corresponding time of the other place in the world belonging to a second telephone system different from the first one, a method for automatically adjusting a time difference between the cellular phone and a connected base station during an international roaming comprises the steps of when a CPU of the cellular phone determines that an associated telephone system is different from that of the connected base station, the telephone system accessing the data base and looking up the conversion table for retrieving a corresponding time of the connected base station with respect to the cellular phone; and showing the corresponding time as a local time on a display of the cellular phone.

The infrared sensing unit is fitted to an edge of a disc coupled to the shaft of the first motor. The rotating speed feed back unit has a rotating disc which is also coupled to the shaft of the first motor. The ultrasonic sensing unit is fitted to an edge of a second disc coupled to the shaft of the second motor such that it can move with rotating of the second disc. The micro controller activates the first motor and the infrared sensing unit to search for a human, and figures out the direction of that human by means of the rotating speed feed back unit. At the same time, the controller activates the second motor for the ultrasonic unit to be directed to the found human; thus, the distance from that human to the device is available.
