摘要： A vibration sensing device, an acceleration sensing system and a method of manufacturing a vibration sensing device wherein the vibration sensing device comprises a flexible disk that is mounted symmetrically about a radial plane and has a mass located on the disk substantially symmetrical about this radial plane which exerts a force that is greater towards the edge than it is towards the centre of the disk. The vibration sensing device is sensitive to on-axis signals and insensitive to cross axis signals.

摘要： The present invention provides an optical fiber sensor for traffic monitoring, which comprises a former consisting of an elongated plate, and an optical fiber wound onto at least one surface of the elongated plate. The elongated plate is flexible in a direction transverse to the at least one predetermined property of an optical signal transmitted through the optical fiber sensor. The resulting sensor has a reduced depth which makes it easier to locate within the surface of a traffic route, has increased flexibility to enable to confirm to the surface of the traffic route, and has good cross axis sensitivity rejection.
