Abstract: A device for use in a packet-oriented transmission network comprises a transmitter arranged to transmit a sequence comprising at least one data packet and a receiver arranged to receive a sequence comprising at least one data packet. At least one data packet in one of the transmitted or received sequence of data packets includes at least one pointer to indicate when a designated data packet in the sequence is to be received and/or transmitted. The designated data packet includes an indication of at least one other device connected to the packet-oriented transmission network.

Abstract: The present invention relates to a hairbrush with a plurality of filaments which is formulated by a mixture of thermo-sensitive color-changing powder and plastic materials, and the color of which varies with temperature, and the method of manufacturing such thermochromic filaments. The hairbrush comprises a handle, a head which has a number of pre-set filament holes on its surface and is attached to the handle by any convenient means, and a plurality of filaments which is formulated by extrusion process from plastic material of 98% to 94% by weight plus a mixture of 2% to 6% by weight comprising melamine plastics of 6%, latent dye of 4.5%, fixing agent of 10%, fatty acid of 0.5% and metallic oxide of 79% by weight and is attached to the filament holes by any convenient means.
