The invention relates to a method of delivering an agent to the pulmonary system of a compromised patient, in a single breath-activated step, comprising administering a particle mass comprising an agent from an inhaler containing less than 5 milligrams of the mass, wherein at least about 50% of the mass in the receptacle is delivered to the pulmonary system of a patient. A net body coordinate system is established for a welded vehicle frame, and upper and lower locating slots are pierced in hinge pillars of the vehicle frame relative to the net body coordinate system. The first leg part has, at a rear side portion thereof, a reinforced large diameter part with a larger diameter than that of the latch engaging part. In a further variation, a modulo arithmetic operation can be employed for a periodic non-linear function.
