A molded respirator and method of making are disclosed, wherein the molded respirator is made from a porous nonwoven web containing meltblown fibers and staple fibers. The actuator assembly includes an operating member having a first end disposed proximate the opening, and a second end extending into the cavity, and, an over-center mechanism disposed proximate the first end of the operating member, distal from the second end of the operating member. The reaction chamber includes a gas distributor configured to provide a flow of gas to a micro-device workpiece on a workpiece holder. The leg parts are fixed on a bottom surface of the printed circuit board. In the method a torque controller of the electric machines is embodied in a form of a sum of a main instruction enabling to attain set torque on a wheel, heat engine torque, and an additional instruction for damping oscillating modes generated by stiffness of a kinematic chain between the heat engine and the wheels. The aft cross beam includes a rear flange that serves as a flexible \u201chinge\u201d for the seat back structure.
