The invention concerns a method for controlling automatic or automated transmission downshift used for power braking and comprising set of predetermined shifting laws, characterized in that it consists, below a certain arbitrary threshold Ethreshold of the accelerator pedal depression, in defining a new downshift law designed to be substituted for the current standard downshift law. When the food container is made of glass, satisfactory mechanical strength of the container can be maintained even when the thickness of a wall of the container is reduced. The specimen is formed by forming a dimple at a surface portion of the preliminary specimen, and ion milling the preliminary specimen having the dimple. The series of requests collectively represent a request for a collection of documents and related metadata included in the comprehensive customer engagement methodology. The automatic gain control loop compensates for any variations in the on-resistance of the semiconductor switch.
