Abstract: A method for automatic management of a timestamp-based synchronization protocol within a packet-based network to synchronize a slave within a synchronization topology including a plurality of masters, the slave clock being locked to a master clock at an initialization time, said method comprising an assessment step of end-to-end packet delay variation on the basis of the slave clock accuracy, over a plurality of (slave, path, master) combinations, each path linking the slave to a master.

Abstract: A spring-powered toy gun ejects small disks, of the type children collect, giving the ejected disks a spin to improve their flight. The disks are first loaded into a separate spring-operated magazine which is then inserted into an aperture on the gun. A transparent window in the gun allows a user to view the magazine's top disk and any insignia thereon. The top of the magazine bears two retaining members that hold the top disk in place. These retaining members are spaced apart from the magazine by the thickness of one disk and, thus, set the thickness of the disks that can be fired from the gun. The top disk is ejected from the gun by a planar propulsion lever driven by a main spring. Pulling back on a trigger moves the main spring and the propulsion lever away from a rest position. When the trigger is pulled fully, the main spring is automatically released and snaps forward causing the propulsion lever to move forward and strike the top disk propelling it from the gun.
