A telecommunications system including a plurality of switches defining an Ethernet ring; a plurality of virtual local area networks defined on the Ethernet ring, defining a number of virtual local area networks (VLANs) equal in number to the number of links; and a ring recovery system configured to recover from a link failure by rerouting traffic to a destination on the Ethernet ring via a VLAN not including a failed link

A fishing bobber for use with a fishing line terminating in a hook is disclosed. The bobber has a body floatable in water and a pair of elongate arms projecting from opposite sides of the body, said pair comprising a first arm to which said line is secured in use and a second arm. The centre of gravity of said bobber can be adjusted such that, in use and in the absence of external forces, the bobber is balanced so as to float in the water with its arms projecting substantially horizontally, and said hook is suspended by the line a user-selectable depth beneath the body. When a fish applies tension to the line, the bobber tips such that the first arm portion extends downwardly from the body; and when a fish releases tension from the line, the bobber tips such that the first arm extends upwardly from the body.

An antenna configuration for a flip type mobile phone is disclosed. The antenna configuration is designed to reduce, to a hearing aid compatibility (HAC) M3 rating or better, any scattered EM field effects that can cause interference to an active hearing aid. The antenna configuration comprises a halfwave type antenna extendable from the lower portion of the mobile phone. The antenna does not share the same vertical axis as the lower portion of the mobile phone when extended. Rather, it forms a tilt angle (α) that extends the antenna away from the upper portion of the mobile phone creating a greater separation distance between the speaker and the antenna. An antenna feed contact couples the antenna to components within the mobile phone. An antenna matching network can tune and attenuate the antenna configuration to enhance operation in the GSM frequency bands.
