Abstract: A coupler for coupling rail vehicles together comprising: an extendable coupling body; an extending mechanism; and a support housing for mounting the coupler to a railway carriage, wherein the coupling body and the extending mechanism are mounted within the support housing, the extending mechanism being arranged to move the coupling body relative to the support housing between a retracted position and an extended position; wherein the coupling body comprises a coupling interface that is arranged to receive connections of the railway carriage for coupling to a coupling interface of a second coupler; wherein a distance between the coupling interface and the support body increases as the coupling body moves from the retracted position towards the extended position; and wherein the coupling interface is arranged to engage the coupling interface of the second coupler upon contact between the interfaces.

Abstract: A carriage connector for connecting railway carriages together includes a pair of wall portions; a floor portion; and a roof portion, wherein the portions form a passage with a first end having an opening and forming a mountable interface, for mounting the carriage connector to a railway carriage, and an opposing end forming a connectable interface. The wall portions are configured to allow their longitudinal length to be varied. The portions are arranged to be retracted to the mountable interface so the wall portions obstruct the opening, defining a closed position of the carriage connector, and may be extended from the mountable interface to form the passage, defining an open position of the carriage connector. The carriage connector is movable between the open and closed positions and the wall portions can pivot about the first end between a first and second position which correspond to the closed and open positions respectively.

Abstract: A communication device (1, 1?, 1?) with at least one wireless communication channel is configured to receive digital pictures and/or video streams from at least one remote source. The communication device (1, 1?, 1?) is configured to test whether at least one person who is/are associated with said communication device by pre-stored person identification data is identifiable in the digital pictures and/or video streams of the remote source, and to process the digital pictures and/or video streams of the remote source only if the result of the person identification test is positive.

Abstract: A multi-channel audio system having multiple loudspeakers is used to obtain information on the location of one or more independent noise sources within an area covered by the loudspeakers. Within the multi-channel audio system, an audio output device has an input for coupling to and receiving audio signals from one or more audio sources; an audio processing module for generating a audio drive signals and providing them on respective outputs to a number of loudspeakers. A sensing module has inputs connected to respective outputs of the audio processing module, for receiving signals corresponding to sound sensed by the loudspeakers. The sensing module includes a discriminator for discriminating between signals corresponding to the audio drive signals and sensed signals from an independent noise source within range of the loudspeakers. A position computation module determines a two or three dimensional position of each independent noise source sensed, relative to the loudspeakers.

Abstract: A method of labelling an image for display on a screen is disclosed together with a computer program, a computer-readable storage medium and apparatus for the same. The method comprises the steps of retrieving the image, displaying the image rotated, and displaying first and second text labels on the image wherein each label identifies a part or feature of the image, and wherein the first text label is displayed in accordance with one labelling scheme, and the second text label is displayed in accordance with a different labelling scheme. Also disclosed is a method of labelling in which a text label is displayed on a rotated image wherein the label is rotated to one of a plurality of possible orientations relative to the rotated image.

Abstract: Power converter circuitry includes a switch mode converter stage and a controller controlling the converter stage and including a digital signal processor. The width of switching pulses applied to the converter stage are controlled by the digital signal processor so as to control an output current from the converter stage.
