A method of forming an integrated circuit module may include interposing an auxiliary PCB between at least one semiconductor chip and a main PCB, the auxiliary PCB having at least one circuit pattern for electrical connection to one of the semiconductor chip and at least one circuit pattern formed on the main PCB. The invention also relates to a device for implementing said process and to a container thus obtained. Access bore plugs are secured in place on the pump housing using one or more threaded retainers. Further, the system may provide an advisory when a movement of a flap handle is detected such that continued movement of the flap handle would place the flaps in a setting that is inappropriate for the measured airspeed.
