Abstract: A pointing device such as a scrolling device or trackball, including a ball formed at least partially from an electrically conductive material, and a PCB including a capacitive proximity sensor, wherein movement data representative of ball movement is communicated by a controller to an interface such as a monitor screen, and wherein an electrical switch is actuable in response to the proximity of the sensed object to the ball, such that when a user is not in contact with or in close proximity to the ball, movement data will not be communicated by the controller to the interface.

Abstract: Rigid, non-woven fibre panels that are used as privacy screens, partitioning, room dividers or as workstation surrounds, for example, are described. The panels are strong and may be self supporting, have good acoustic properties, and preferably have a substantially smooth surface. They are made from a single, substantially homogeneous, layer of polyethylene terephthalate (PET) fibres, of which a substantial proportion may be of recycled PET. The panels are generally produced by mixing PET fibres into a web, which is then carded, cross-lapped, needle punched, calendered and thermally bonded, preferably using a heated roller.

Abstract: A substrate comprising a single layer of compressed fibrous polyethylene terephthalate, his-density polyethylene, polyvinyl chloride, low-density polyethylene, polypropylene, polystyrene or acrylonitrile butadiene styrene, being substantially rigid and having a thickness of between approximately 6 mm and approximately 12 mm.
