Abstract: A method, apparatus and system are disclosed. The system includes a portable wireless communication device operable with a wireless communication network. The portable device receives information from the network. The portable device can transmit to the network a request for an address from which additional information is available. The network can supply the address to the portable device, which can then transmit the address to another device.

Abstract: A method and equipment implementing the method for processing digital image information. The image information consists of a bit stream comprising a first set of successive source values, for which a corresponding output value can be determined. In the method it is read a source value, and it is determined an output value corresponding to the source value. Further, it is determined a residual part corresponding to the difference between the source value and the output value; it is calculated the sum of said residual part and the next source value; said sum is used as the next source value as a response to said sum being lower than or equal to a predetermined threshold value. The invention provides a fast colour dithering method for such solutions in which the processing time of an image is desired to be the shortest possible.

Abstract: A new functionality in a fax communication system including a PC with a virtual data port (DTE) and a fax modem (DCE), having an infrared (IR) connection between them, wherein the DCE is capable of indicating to the local infrared communications, i.e., IrDA IrCOMM, port or interface the type of the software flow control, either local or end-to-end, so that the local and the remote IrCOMM ports can be made to function such that:______________________________________ IF an XON/XOFF character is received from the client AND the mode is end-to-end AND the SW flow control is enabled, THEN the XON/XOFF character is handled as flow control and the character is transmitted to the host IrCOMM. ______________________________________A new interface primitive at the interface of the IrCOMM in the DCE requests the desired mode and if the desired mode is "local", the XON/XOFF characters are not transmitted to the host system when SW flow control is active.
