Abstract: A therapeutic applicator is positioned using a positioning system that includes a passive positioning assembly and an active positioning assembly. Each assembly has multiple degrees of freedom. The passive positioning assembly sets, with respect to a base of the system, an initial forward-backward position of the active positioning assembly, an initial vertical position of the active positioning assembly, and an initial angle of tilt of the of the active positioning assembly. The active positioning system sets an axial position of the therapeutic applicator and a rotational position of the therapeutic applicator.

Abstract: A hybrid air conditioning system for a combustion engine vehicle. When the combustion engine is running and a rechargeable battery unit is not at full charge, an electric machine is configured by an MCU control unit as mechanically coupled to the combustion engine, and a battery charger is configured as electrically connected to the rechargeable battery unit such that the electric machine generates electric power to recharge the rechargeable battery unit. When the combustion engine stops and air conditioning is required, the rechargeable battery unit is configured by the MCU control unit as electrically connected to a motor drive, and the electric machine is configured as mechanically coupled to the compressor to provide mechanical power to drive the compressor. This allows the automobile air conditioning system to operate for a limited period of time after the combustion engine stops.

Abstract: The present invention provides a surgical manipulator including a manipulator arm, an end-effector held by the robotic arm, surgical tools held by the end-effector and manipulator joints, particularly right-angle drive devices for transmitting rotational motion in one axis to a perpendicular axis.

Abstract: A DC to DC converter includes a switch, a diode, and a capacitor connected in series with an inductor. The capacitor and inductor provide a resonant time period and are connected in series with the switch and the diode. A control circuit provides an on/off signal to the switch and has a switching time period longer than half the resonant time period.
