Abstract: A method is provided, comprising transmitting a radio transmission using a radio transmitter circuit connected to a corresponding antenna of a mobile electronic device, detecting a change in transmission conditions, and adjusting the power radiated by said antenna in response to a detected change. A mobile electronic device is provided, comprising a radio transmitter circuit, an antenna connected to said radio transmitter circuit, and a controller adapted for transmitting a radio transmission using said radio transmitter circuit, detecting a change in transmission conditions, and adjusting the power radiated by said antenna in response to a detected change.

Abstract: In accordance with an example embodiment of the present invention, a method is presented which comprises searching for at least a device that is capable of a point-to-point transmission of media data. If such a device is not selected for the point-to-point transmission, a transmission of the media data is started on a second communication interface using a broadcast transmission.

Abstract: The present invention provides a method for maintaining continuity of radio transmissions, particularly unlicensed low-power FM transmissions, comprising transmitting frequency modulated media data via a radio transmission on a carrier frequency, interrupting the transmission of the media data while maintaining the transmission of the carrier frequency, transmitting a frequency modulated substitute signal during said interruption, and continuing the transmission of said frequency modulated media signal.

Abstract: A method comprises detecting whether or not a frequency modulation broadcast receiver is tuned to an overdeviated frequency modulated broadcast, or is at a location where overdeviated frequency modulated broadcasts exist or has received a user input indicating the presence of an overdeviated frequency modulated broadcast; and in response to the detection, automatically adjusting operation of the frequency modulated broadcast receiver. Automatically adjusting operation comprises adjusting one or more parameters or settings in such a way as to alter the susceptibility of a speaker arrangement to the possibility of being overdriven by overdeviated frequency modulated broadcasts.

Abstract: In accordance with an example embodiment of the present invention, an apparatus is presented that comprises a multichannel audio transmitter which has a first mode for transmitting a multichannel audio signal and a second mode for transmitting at least a first and a second audio signal, each having fewer channels than the multichannel audio transmitter. A controller is configured to switch the multichannel audio transmitter from the first mode to the second mode when the first audio signal becomes available.

Abstract: A mobile telephone handset is provided with a connector (8) and circuitry (18, 19) which permits universal serial bus (USB) and single-ended (SE) modes of data transmission with another device such as a personal computer, another mobile telephone handset or keyboard.

Abstract: The invention provides a method for broadcasting via radio transmission, comprising the steps broadcasting data on a first radio frequency, transmitting an indication of a second frequency via said broadcast on said first frequency, establishing a synchronous second broadcast of said data on said second frequency, and discontinuing transmission of said broadcast on said first frequency.

Abstract: A radio handset (20) is provided with an integral stand (22)either hinged to its main body or battery, to support it in its upright position. The stand may be in the form of a cover, such as a flip or slide and the operation of the handset may be controlled depending upon the position of the cover.

Abstract: A radiotelephone proximity detector, comprising a first proximity unit associated with a radiotelephone and a second proximity unit associated with a user wherein the second proximity unit includes a transmitter for transmitting a proximity signal, and the first proximity unit includes a receiver for receiving the proximity signal and an analysis unit for estimating the proximity of the first and second proximity units on the basis of the received proximity signal, the first proximity unit being operable when the estimated proximity of the first and second proximity units exceeds a threshold to cause the radiotelephone to change into an operating mode in which its normal use is prevented.

Abstract: An interface between unsynchronised devices such as ASICs. The interface comprises a delay means which synchronises the write strobe of the first device with the system clock of the second device, thus enabling the transfer of data from the first device to the second device. The interface requires fewer gates per register in the second device than prior art interfaces.
