Abstract: A lockable container adapted to fit within a docking area in a vehicle comprising three side panels, a bottom panel, a top panel and fourth side panel comprising a lockable door arranged to define a cavity within which goods may be stored wherein at least one of the panels is constructed of a plastics material and is removable from the other panels. The container is light and may be repaired on-site and thereby remain durable and replacement of at least one side panel enables rapid repair of the container when damaged through collision with fixtures in the vicinity of use. The container may be used on a vehicle during a journey to dispense goods for example on an aircraft, bus or a train.

Abstract: A near field RF communicator has: an antenna operable to generate an RF signal to enable inductive coupling via the magnetic field of the RF signal between the antenna and another near field RF communicator or RF transponder in near field range; and a signal generator operable to generate a multi-level digital sine wave drive signal to drive the antenna to generate the RF signal, wherein the signal generator comprises a selector operable to select one or more digital sequences to provide one or more digital signals from which the digital sine wave drive signal is generated.
