Disclosed is a package delivery mechanism for use by an unmanned aerial vehicle (UAV). The package delivery mechanism includes a gravity activated locking mechanism to lock and unlock a package attached to the UAV based on the weight of the package. When the package is attached to suspension means of the UAV that lowers the package to the ground from the UAV, the locking mechanism automatically engages with the package and keeps the package locked to the suspension means, due to the weight of the package. When the package is lowered and reaches on the ground, the weight of the package is offloaded from the suspension means, which enables the locking mechanism to be disengaged, thereby releasing the package. The package delivery mechanism includes a severing module to sever the suspension means from the UAV.

An assembly for cutting a polystyrene block includes a lever element, adapted to be coupled to a hot cutting element, and a control device connected thereto. The lever is arranged so that a potential inclination of the hot cutting element can be followed during the feed motion of the cut, the lever further cooperating with a sensor set to detect a potential inclination deviation of the lever during the cut, in relation to an initial reference inclination, the control device being set to vary feed motion speed depending on the detected variation of inclination.

In conventional machining process, it is sometimes desirable to cut internal features with sharp corners. But normal machining process using end mills fail to achieve sharp corners, as they leave a fillet material equal to tool radius unmachined. In this invention, it is proposed to design a special tool and a 4-axis robotic handling system, to achieve sharp corner radius even for internal features, at the same time achieving high material removal rates. An intelligent cutting method is proposed in this invention for cutting big blocks of materials using multiple wires. The proposed method provides several benefits like achieving high dimensional accuracies, sharp corners, easy to handle shredded scrap materials etc. A method for automatically generating the cutting tool path for single and multiple nested pipes is also proposed.

A device for slitting a tubular workpiece into strips includes radially disposed cutting members. The device may include a tapered infeed mandrel for maintaining tension on the tubular workpiece being slit and optionally an exit mandrel. In embodiments, the position of the radially disposed cutting members may be adjustable.
