Abstract: A communication device (9) has a Wi-Fi® device (14) for communicating with another communication device (9). The Wi-Fi® device (14) has one output connected to an antenna (13) and another output connected to a coaxial cable jack (10) via a coupler (11). The antenna (13) therefore provides a wireless communications link and the coupler (11) provides a wired communications link. A diversity switch (18) of the Wi-Fi® device (14) uses antenna diversity switching provided for in the Wi-Fi® standards to switch between the wireless communications link and the wired communications link.

Abstract: The invention provides for an audio system 10 comprising an audio signal generating means (12) for output of an audio signal (24), and a remote control device (14) for control of the audio signal generating means (12), the audio signal generating means (12) including means for including an identification signal within the audio output (12) and which serve to identify the audio signal generating means (12) from which the audio signal is output, the remote control device being arranged to receive the identification signal so as to identify the source (12) from which a particular audio signal (24) is output.

Abstract: A digital camera includes an image sensor; a buffer memory adapted to receive images from the image sensor and to store the images therein; an image processor adapted to receive selected images and to process the selected images, including applying a video compression algorithm to the selected images; an image storage device adapted to store the processed, selected images; and an image selector adapted to select the selected images among the stored images in the buffer memory based on at least one image selection criterion, and to cause unselected stored images to be discarded from the buffer memory.

Abstract: A method of acquiring a received spread spectrum signal, especially a GPS signal, is disclosed together with a spread spectrum signal receiver and a cellular telephone incorporating such a receiver. The method comprises the steps of: providing a replica signal containing a pseudorandom noise code, corresponding to that of the spread spectrum signal; providing a subject signal containing two fragments of the spread spectrum signal initially received during respective time periods between which a further time period elapses; and coherently correlating the replica signal with the subject signal over the two fragments.

Abstract: A method of enabling a user to define a call handling profile for a telephone is disclosed. The method comprising the steps of presenting on the telephone display (14) a plurality of groups of telephone numbers, or identifiers associated therewith, for selection (22) of at least one of them by the user; presenting on the telephone display a plurality of rules for handling incoming calls for selection of at least one of them by the user; and associating the or each group selected by the user with the or each rule selected by the user to define the profile.

Abstract: A method of determining the position of a transmitter (BS1) located in the vicinity of a mobile communications device (MS1) which is able to determine its position is disclosed. The method comprising the steps of: (i) moving the mobile communications device (MS1) to a plurality of reference locations (pn); (ii) determining the position of the mobile communications device (MS1) and the range from the mobile communications device (MS1) to the transmitter (BS1) at each reference location (pn); and (iii) determining the position of the transmitter (BS1) using the positions and corresponding ranges determined in step (ii). Also disclosed is a method of determining the position of a mobile communications device (MS1) which utilizes the above method.
