Abstract: An actuator for a side door of a motor vehicle is described, which brings about automatic opening or closing of the side door depending on a signal and has a device for holding the side door in any open position. The holding device is realized by a function of the electric motor itself, according to which function the control device initiates a short-circuit function of the motor phases when the motor is activated, which causes a high current flow and thus a high torque for holding the side door open. By short-circuiting the motor phases, no additional components are required, since this is a special activation function of the motor.

Abstract: A closed system transfer device includes a first adaptor and a second adaptor that attach with one another in a coupled state to form a sealed fluid passage between two reservoirs. The first adaptor can be attached to a first reservoir, and the second adaptor can be attached to a second reservoir. One or both adaptors can include a septum that engages another septum during coupling and decoupling to prevent liquid or vapor from being released to the environment. The device can also include a vent line that equalizes pressure between the two reservoirs. The vent line can include at least one filter to filter gas in device. In addition, or in the alternative, the vent line can be connected in fluid communication with an inflatable membrane that stores gas inside the device and assists in equalizing pressure.

Abstract: A fluid transfer device for use in medical/pharmacological applications a method of use, and a closed medicine transfer system. The fluid transfer device includes a first adapter unit having a first sealing element and a second adapter unit having a second sealing element. The first adapter unit and second adapter unit, when connected, provide a fluid connection between the first adapter unit and the second adapter unit and prevent, when disconnected, the transfer of fluid out of the first adapter unit and the second adapter unit. A fluid connection between the first adapter unit and second adapter unit is established by a combined pressing movement towards one another and a rotational movement with respect to one another, only after a constant pressure has been set which the first sealing element and the second sealing element apply against each other.
