Abstract: The invention relates to a method and arrangement for creating a virtual keyboard for a terminal (800) used in a cellular network. The virtual keyboard is generated using an IR transceiver arrangement (12) in which a reflection from an obstacle (15) placed in the field of IR transmitters is registered by discrete IR receivers. The received reflection data are processed in a neural network arrangement (33). The purpose of the data processing is to find out the virtual key position/function that the received reflection data corresponds to.

Abstract: A method and system for providing selective access to appliances by terminals in a smart environment is provided. Each terminal and appliance is assigned a unique identification code (UID). Appliances and terminals wireless transmit their UID and receive UIDs transmitted by other appliances and terminals. Upon receiving a terminal's UID, an appliance queries a database to determine whether the terminal is authorized to control that appliance based on authorization information stored in the database. An owner may be notified id a terminal without authorization attempts to control an appliance or enters the environment.

Abstract: The invention relates to a method for manufacturing a cellular phone (200), and to a cellular phone manufactured using said method. In the manufacturing method according to the invention, the platform, which comprises the essential electronic components of the cellular phone, is manufactured using mass production technology. A working cellular phone (200) also includes electronic custom parts which are integrated in a structural element in the phone. A customer can modify the properties of his phone by replacing the structural element with another one which comprises different components. A custom part may also be changed by the customer himself.
