Abstract: A method of synchronising audio content arranged to be played by a second device with video content played by a first device, wherein the second device includes a camera, comprises: capturing at least a portion of the video content with the camera; performing image recognition on the captured video content to identify a set time point in the audio content; and commencing playing the audio content from a selected time point in the audio content corresponding to the set time point, such that the audio content is synchronous with the video content. A method of pre-preparing video content for use in such a synchronisation method is also described.

Abstract: The present invention relates to the use of acoustic waves for the manipulation and sorting of particles and cells. In an embodiment, there is provided a microfluidic device for manipulating a particle in a fluid suspension, the device comprising: (a) a substrate; (b) a channel defined in the substrate, the channel having an inlet for receiving the fluid suspension and an outlet for discharging the fluid suspension; and (c) an acoustic source configured to deliver a travelling surface acoustic wave transverse the flow of the fluid suspension in the channel, wherein the acoustic source is an interdigital transducer (IDT), the IDT comprises a plurality of concentric circular arcs having a tapered end directed at the channel, and the tapered end has an aperture of between 4 ?m and 150 ?m. In an alternative embodiment, the device comprises a second channel disposed intermediate the first channel and the acoustic source wherein the first and second channels are connected by a pumping channel.

Abstract: A microfluidic device for separating or sorting particles in a fluid including: a substrate; a plurality of interdigital transducers on the substrate; a microfluidic channel adapted to have fluid flow within, located over the interdigital transducers, the microfluidic channel having a width, wherein: the interdigital transducers are located within the width of the microfluidic channel; and application of a signal to the interdigital transducers produces a force field at an angle to the fluid flow direction within the microfluidic channel.

Abstract: An object is examined by detecting properties of the object at different times within a space formed by spatial frequencies. This is done such that temporally consecutive recordings are made in overlapping regions of the spatial frequency space and also in regions of the spatial frequency space that differ from one another.
