Abstract: The present invention relates to a system, method, and computer program product for determining the flow rate of a fluid. The system, method, and computer program product generate a thermal sensor based mass flow rate for the fluid, where the thermal sensor based mass flow rate is determined at least in part from the thermal sensor signal (36). The system, method, and computer program product generate a pressure sensor based mass flow rate for the fluid, wherein the pressure sensor based mass flow rate is determined at least in part from the pressure sensor signal (51a). The system, method, and computer program product generate at least one calibration factor (?) using the thermal sensor based mass flow rate and the pressure sensor based mass flow rate. The system, method, and computer program product may generate a calibrated pressure sensor based mass flow rate by using the at least one calibration factor (?) to modify the pressure sensor based mass flow rate.

Abstract: An improved rocker-type switch has a toggle member pivotably mounted on a central pivot member in a frame of a top housing part joined to a bottom housing part holding switch contacts in a modular block subassembly. A pair of movable contact arms is actuated by spring-biased actuator members held in the central pivot member. The modular block subassembly has an insulative top block member, a top switch contact plate with switch contacts on upright tabs inserted through slots in the top block member, an insulative bottom block member sandwiching the top switch contact plate, and a bottom switch contact plate having switch contacts on upright tabs inserted through slots in the bottom and top block members, forming a pair of opposing switch contact positions for the movable contact arms. The switch contact plates have clip portions for inserting the tabs of respective switch contact terminal plates therein. For different switch configurations, e.g.
