Abstract: A continuously variable power split transmission (CVPST) system is described for use in a hybrid vehicle. The vehicle has a first motor, such as an internal combustion (IC) engine and a second motor, such as an electric motor. The system has a step-up gearbox for providing additional fixed speed ratios to extend overall transmission conversion range (CR) of the system. The system also has a speed variator and a countershaft being operatively connected to the second motor of the vehicle so that any power input applied by the second motor to the countershaft reduces the power flowing through the speed variator. Also, an adjustment of the variator speed ratio iv allows a passage from underdrive iUD to overdrive iOD range of speed ratios in the step-up gearbox to be synchronized.

Abstract: An automobile having a chassis and an outer cladding in the form of an airfoil with the top roof wall forming the pressure surface and the bottom wall the forming the suction surface with the front of the automobile acting as a leading edge and in the rear, the trailing edge.

Abstract: A chair comprises a base with a fixed stem extending vertically from the base and a track member mounted to the top of the stem. The track member is a segment of a circle, the center of which is forward of the chair and coincident with either the knee or ankle of the person utilizing the chair. A carriage having wings which are concentric with the track slides in the track. A seat is mounted on the carriage. The disclosure also relates to a backrest for a chair which pivots around an axis coincident with the H point axis relative to the chair, and to a chair which can shift in response to a person sitting on the chair, the chair also comprising a backrest which pivots around the H point.
