Voltage regulator circuitry is provided. The methods may include receiving at one or more computing devices information about a user obtained at a point of interaction; generating using the one or more computing devices, based at least in part on the information, an individualized curriculum of engagement for the user; and delivering using the one or more computing devices the individualized curriculum of engagement to the user. As a result of this manufacturing method relating to the forming cheeks, the manufacturing costs of the hot-forming tool can be significantly lowered because a high-expenditure mechanical cutting machining of the forming cheeks is only still required in the area of the mounting surfaces as well as the mutually facing exterior sides. The switch switches between a state of electrically connecting the auxiliary battery and the system main relay, and a state of electrically connecting the auxiliary battery and the actuation member.
