Abstract: An actuator assembly comprising: a support structure; an image sensor assembly comprising an image sensor having a light-sensitive region, the image sensor assembly being suspended on the support structure in a manner allowing movement of the image sensor assembly relative to the support structure; and at least two flexible printed circuits, each electrically connected at one end to the image sensor assembly, wherein the flexible printed circuits fold around the image sensor assembly such that their other ends are at the same side of the image sensor assembly.

Abstract: Disclosed is a method of synchronising an image sensor with a PWM driver operable to drive an arrangement associated with the image sensor, wherein at least one synchronisation signal produced by the image sensor is used to reset the PWM driver and the at least one synchronisation signal is delayed before being used to reset the PWM driver such that the switching on or off of the at least one synchronisation signal occurs at a defined time in relation to a sensitive period of the image sensor's operation.

Abstract: A loudspeaker comprises a region devoid of electroacoustic transducers and at least two groups of electroacoustic transducers at the periphery of the region. Each of the groups is configured to produce a different sound field representative of an audio signal and each of the groups comprise a different set of transducers. This allows a more compact loudspeaker to be provided because the transducers can be located around the periphery of a visual display screen. Sound quality is not compromised because groups of transducers forming a subset of the totality of transducers are used for each sound signal, thereby avoiding alias beams.
