This invention relates to a process for making toothbrushes, in particular an injection moulding process. In one example, determining the likelihood of legitimacy includes determining the likelihood that the provided identifier is a valid identifier and determining the likelihood that the provided identifier was assigned to the purported assignee. An at least semi rigid front restraining member is coupled to opposite sides of the mandible mask and adapted to extend over the snout of the animal. The first and second arms can be generally planar linkages. At least one of the walls of the grain tank is movable relative to the floor between an expanded harvest position and a folded transport position. The system consists of a module within each of the devices that is operable to perform login, synchronization, data loss recovery, and conflict avoidance and resolution functions.
