Abstract: Apparatus for an electrically powered fluid feature comprises a unit including a fluid pump and a rechargeable power source arranged to provide power to the pump for operation of the fluid feature. The power source may be rechargeable via electrical contacts. The unit may comprise upper and lower housing portions that are separable to allow cleaning, replacement or recycling of components. The unit may be removably installed in a reservoir, which is supported within a container by adjustable supports.

Abstract: An electronically controlled brake booster for a vehicle brake system including a housing having a vacuum chamber and a servo chamber separated from the vacuum chamber by a movable wall. The brake booster further includes a control valve operable by an electromagnet. The control valve is coupled to the wall for common relative movement with respect to the housing. The electromagnet is connectable to a control unit generating a drive signal to operate the electromagnet. A braking pressure generation unit is connected to the movable wall for generating a braking pressure for a brake of the vehicle in dependance on the position of the movable wall. The drive signal is generated in the control unit in dependance on a control parameter, the parameter being adjusted in dependance on a dead time of the braking pressure between supplying the electromagnet with the signal and a rising of the braking pressure in response thereto.
