A photovoltaic module includes a first protective element, a second protective element, photovoltaic cells that are located between the first protective element and the second protective element, an envelope in which the photovoltaic cells are encapsulated. The envelope links the first protective element to the second protective element and includes a first portion that is located between the photovoltaic cells and the first protective element, and a second portion that is located between the photovoltaic cells and the second protective element. The disassembly method includes separating the photovoltaic cells with respect to the first protective element and cutting the first portion of the envelope by an abrasive wire.

A transverse cutting system for a machine for the production of plastic film includes a supporting structure carrying a cutting unit, which are moved between a rest position away from a path of a plastic film being wound and an operating position along the path of the plastic film; a rotating support carrying a hot wire; a rotating cap, associated to an idle roller and arranged transversally to the path of the plastic film that is moving forwards, and an actuator, which controls the rotation of the rotating support carrying the rotating cap and causes the rotating cap to interfere with the plastic film before the hot wire also interferes with said plastic film. The same plastic film, owing to the friction force generated by the rotating cap, entrains it with it, causing the rotating cap to equalize the linear velocity of the plastic film.

A levelling machine includes a pair of spaced apart rail assemblies, a gantry assembly and a face mill assembly. The spaced apart rail assemblies define an x axis. The gantry assembly is moveably attached to the pair of spaced apart rail assemblies whereby the gantry assembly defines a y axis. The gantry assembly is moveable in the x axis along the pair of spaced apart rail assemblies. The face mill assembly is moveably attached to the gantry assembly and is moveable in the y axis along the gantry assembly. The face mill assembly has a plurality of saw blades, the saw blades being generally in an x-y plane defined by the x axis and y axis. The saw blades have a plurality of teeth that extend downwardly generally in a z axis. The face mill assembly is moveable in the z axis.

Methods and apparatus relating to provision and/or utilization of a hidden feature for accessing and/or repairing mobile devices are described. An embodiment includes a wire physically adjacent to an adhesive. The adhesive bonds a first portion of a computing device and a second portion of the computing device. The wire is capable of being heated in response to application of electrical voltage or current. In turn, the heated wire causes cutting of the adhesive to allow for physical separation of the first portion of the computing device and the second portion of the computing device. Another embodiment utilizes a hidden end of an opening in a computing device to hide a fastener. Other embodiments are also disclosed and claimed.

A package delivery mechanism (PDM) of an unmanned aerial vehicle (UAV) is described. The PDM 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 a suspension member of the UAV, the locking mechanism automatically engages with the package and keeps the package locked to the suspension member, due to the weight of the package. When the package is lowered and reaches the ground, the weight of the package is offloaded from the suspension member, which enables the locking mechanism to be disengaged, thereby releasing the package.

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.

Systems, devices, and methods including: a latching mechanism comprising: a first latch configured to attach to a door of an unmanned aerial vehicle (UAV); a second latch configured to attach to a portion of the UAV distal from the first latch; a string connected between the first and second latch, where the string secures the door shut; at least two radio modules in communication with a ground control station; and at least two burn wires in contact with a portion of the string between the first latch and the second latch; where current from a backup battery passes to at least one burn wire when the burn signal is received, where the burn wire causes the connection between the first latch and the second latch to be broken and the door of the UAV is separated from the UAV, and where the parachute is deployed when the door of the UAV is separated from a rest of the UAV.
