Abstract: The present invention relates to a an active pillow system and a method for manipulating a person's resting conditions, wherein the actual resting conditions of the person are determined by a sensor unit, an actigraph, a temperature sensor and/or a humidity sensor for instance, and wherein an acoustic synthetic jet cooling mechanism, is triggered by the determined actual resting conditions for manipulating the person's resting conditions.

Abstract: A method of outputting multimedia content such as a video clip on a plurality of user devices (11, 12, 13) allows users of their devices to view the video clip in substantially time synchronised manner. Devices (10,11,12) communicate with each other to exchange control signals over a telecommunications network via communications links (13,14,15). The video clip is provided to user devices in advance of viewing so that during subsequent viewing only small control instructions denoting ‘play’, ‘stop’, ‘pause’ and the like need to be communicated between devices, where such small instructions suffer less from bandwidth constraints and latency of the communications network.
