摘要： A network system includes a server, an access point connected to the server for transmitting wireless data or receiving wireless data for the server, and a station for receiving wireless data from the access point and transmitting wireless data to the access point. The station has a first key. A ciphering key updating method includes: authenticating the station with the first key; if authentication succeeds, the station transmitting identification data to the access point; and if the identification data matches registration data stored in the server, transmitting a second key to replace or update the first key.

摘要： A method for dynamically simplifying an international call in a cellular phone utilizes a conversion table for storing system codes of a plurality of network companies worldwide and their international access codes, and a phone record for storing a plurality of telephone numbers having international access codes respectively of different called parties in the database thereof. The cellular phone is able to determine the current location area while calling in international roaming and find the correct international access code from the conversion table in accordance with a system code received from a proximate network company, for replacing the international access code in the telephone number searched from the phone record.

摘要： 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.

摘要： A device for finding a position of a human comprises a micro controller, a pyro-electrical infrared sensing unit, a first motor, a rotating speed feed back unit, an ultrasonic sensing unit and a second motor. 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.
