The antenna assembly (1) comprises an extendible mast (2) constructed and arranged so as to be configurable between a coiled form and an extended form. The extended mast (2) is resiliently biased in the form of an elongate tube having a slit along its length. The coiled mast is wound about an axis extending transversely to the longitudinal extent of the mast. An antenna (6) is integrally coupled to the mast such that when extended, the mast supports and positions the antenna, and when coiled, the mast and antenna are coiled together.

Abstract: The present application describes methods and apparatus relating to sensor assemblies and fiber optic assemblies. In one example, a method is described of deploying a sensor assembly (1) for sensing a property associated with a structure of interest (100). The sensor assembly (1) includes an elongate member (2) configurable between a coiled form and an extended form and at least one sensor (3) disposed along at least a part of the longitudinal extent of the member.

Abstract: An apparatus and method for manufacturing a composite product from plural components are disclosed. The apparatus (10) comprises a conveyor assembly comprising back-to-back conveyor belts (16,18) which are drivable such that components can be received between the conveyor belts at an input end of the conveyor assembly and can be moved through the apparatus between the conveyor belts. A press (30) is arranged to consolidate the components into a flat form by the application of pressure to the components between the conveyor belts. The conveyor belts pass through a die (71) which is arranged such that consolidated components between the conveyor belts are shaped into a non-flat profile as they move through the die. A heater (38) is arranged to apply heat to set the components into the non-flat profile to form the composite product (57).

Abstract: The invention provides an extendible member (10) which is configurable between a coiled form (11) and an extended form (12).

Abstract: The invention provides an extendible member which is configurable between a coiled form and an extended form. The extendible member comprises: a primary member comprising a sheet of material resiliently biased in a slit tube form, wherein the slit tube can be opened out at the slit to assume an open form in which it has a flattened cross section; at least one resilient secondary member having first and second connections to the primary member at respective different circumferential positions on the primary member, wherein in the extended form, the primary member is in its slit tube form and the resiliency of the secondary member causes at least part of the secondary member to displace towards the slit in the primary member to provide torsional and axial stiffness to the primary member, and wherein in the coiled form, the primary member is in its open form and the secondary member conforms to the flattened cross section of the primary member so that primary and secondary member can be co-coiled.

Abstract: The present application relates to methods of protecting a cable or cables, methods of repairing a cable or cables, to a sleeve, to a cable or cables in combination with a sleeve, and to a dispenser for a sleeve. The method of protecting a cable or cables comprises uncoiling a protective sleeve (1) and forming the sleeve around a length of the cable or cables (10). The sleeve comprises a fibre-reinforced composite body which has an extended form in which it is resiliently biased in the form of an elongate tube (4) having a slit along its length by which the sleeve (1) can be opened to receive the cable or cables (10) so that the sleeve self forms around the cable or cables due to its resilience. When coiled (5) the sleeve is opened out at the slit to assume a flattened cross section.
