An unmanned aerial system for transporting and delivering packages, comprises an unmanned motorized aircraft and a non-motorized aerostatic device having aerostatic lift and being able to be coupled to the motorized aircraft, for transporting at least one package from a take-off site to a delivery site. This aerial system cooperates with a site for storing and distributing aerostatic modules each having a predetermined modular aerostatic lift, the storage and distribution site being located in the vicinity of the take-off site and being configured to deliver a set of j aerostatic modules on demand, which modules are secured by coupling means, so as to supply an aerostatic device with static lift that is substantially greater than or equal to the overall weight of the package to be transported and of the aerostatic device.

A method to manufacture a hairspring of a timepiece movement, which includes: producing a malleable elongated element in a form of under a fiber or ribbon form, from a first heated material capable of guiding light; conforming the malleable elongated element in order to achieve into a spiral form; and handling processing the spiral form thus created in order to obtain a hairspring for providing both a mechanical oscillating function in a balance wheel and a light guiding guide lighting function arranged for in situ adjusting of a mechanical performance of said hairspring. The conforming includes coiling the malleable elongated element around a rotating mobile conformation tool, and receiving the malleable elongated element in a guiding channel within a guiding mechanism and guiding the received malleable elongated element via mobile equipment turning on an inner periphery of the guiding mechanism.
