Abstract: An apparatus, method and computer program wherein the apparatus comprises: a housing comprising a convex portion configured to enable the apparatus to rock in response to an impulse provided by a user; and a processor configured to enable a function of the apparatus to be performed in response to the detection of the rocking of the apparatus.

Abstract: An earplug for water sports has a wing adapted for fixation of the ear plug in the outer ear of the user, and has a tube of a funnelled and tapered configuration forming an audio channel extending within the ear canal. The wing is arranged in an angled position in relation to the tube for adaption to the anatomy of the ear, and has a flexible portion for adaption to the outer ear. A hollow tip element with flanges for sealing the ear canal and for fixating the ear plug in the ear canal surrounds a narrow portion of the tube. The tip element has a nose end with recessed areas for forming a free air canal. The ear plug has a mesh with an open area structure for air permeability that allows sound to pass the mesh and through the audio channel, while preventing water and wind from entering the ear canal.

Abstract: A process for the preparation of an aqueous suspension of a solid free-radical forming initiator, a plant for the preparation, an initiator suspension and use of the suspension in polymerization of ethylenically unsaturated monomers. The process for the preparation of the suspension comprises the steps of:(a) heating the initiator to its melting point;(b) finely dividing the initiator in water while it is in a molten state;(c) rapid cooling so that the initiator is in a molten state for a period of time which is less than about 5 minutes.The initiator suspension has very small particles and a narrow particle size distribution whereby at least 50% by weight of the particles are smaller than 5 .mu.m and at least 90% by weight of the particles are smaller than 10 .mu.m.

Abstract: An initiator suspension for use in the suspension polymerization of ethylenically unsaturated monomers is prepared by (a) heating the initiator to its melting point; (b) finely dividing the initiator in water while it is in a molten state; and (c) rapidly cooling so that the initiator is in a molten state for a period of time which is less than about 5 minutes. The initiator suspension has very small particles and a narrow particle size distribution whereby at least 50% by weight of the particles are smaller than 5 .mu.m and at least 90% by weight of the particles are smaller than 10 .mu.m.
