摘要:
A weapon system includes a cartridge and a fire control apparatus have been developed for generating a projectile with a selectable launch velocity. The cartridge includes multiple primers and propellant chambers which may be individually selected by the fire controller so as to fire the projectile at a selected launch velocity. Additionally after firing the selected primers and propellant charges, the fire controller sends a second firing signal to all remaining primers after a suitable delay. The second firing signal ensures that all remaining propellant is initiated and consumed, thus rendering the cartridge safe to eject. The delay between the first firing signal and the second firing signal is sufficient to allow the projectile to be expelled from the cartridge so that the launch velocity is not affected by the combustion of the remaining propellant.

A balance device comprises first, second and third components. The first, second and third components include substantially cylindrical first, second and third central portions, respectively, and which are coaxial with one another. The balance device further comprises a first set of connectors for coupling the first component to the third component and a second set of connectors for coupling the second component to the third component. The connectors accommodate axial movement in response to relative axial forces between the first and second components and minimise rotational movement about the axial direction in response to relative axial torque between the first and second components.

The present disclosure relates to an exoskeleton system to be worn by a user. The system includes a load carriage arrangement configured to carry an applied load. The load carriage arrangement includes a frame, for example a frame for a backpack, and at least one non-rigid member. The at least one-non rigid member is arranged to transfer at least a first part of the applied load carried by the load carriage arrangement to the ground bypassing the user's musculoskeletal system. The system may further include a load sharing arrangement configured to transfer a second part of the applied load to the user's musculoskeletal system.

The delay between the first firing signal and the second firing signal is sufficient to allow the projectile to be expelled from the cartridge so that the launch velocity is not affected by the combustion of the remaining propellant. Selection of primers may be manually performed or a laser range finder may be used to automatically select the primers based on an estimated range to a target. The system may be used for accurately and effectively firing non lethal rounds over short distances.

The present invention relates to a clamp that can be used for repairing a rupture in a pipe. The clamp includes a wrapping assembly comprising strapping that at least partially extends about the pipe, an adjustment device that is suitably in form of a claps for adjusting the effective length of the strapping about the pipe and a tensioning device that is suitably in the form an over center lever mechanism that is operable to place the wrapping assembly under different tensions.

A method of segmenting objects in an image is described. The method applies a Top Hat algorithm to the image then constructs inner and outer markers for application to the original image in a Watershed algorithm. The inner marker is constructed using binary erosion. The outer marker is constructed using binary dilation and perimeterisation. The method finds particular application for first level segmentation of a cell nucleus prior to detailed analysis.

The present invention relates to a system for monitoring the health of mechanical and structure components of a machine. For example, the present invention is capable of monitoring the operational integrity of critical components of critical components of an aircraft such as the gearbox of a helicopter. The present invention is based on the principle of detecting a traceable substance when the substance is released from the component being monitored in the event of predetermined condition being satisfied, such as exceeding the operational temperature of the component, or a fault in the component occurring, such as a crack being formed.
