Abstract: A motor vehicle oil pump, including: a pump body, an external rotor having a first plurality of lobes, an internal rotor having a second plurality of lobes configured to engage the first plurality of lobes of the external rotor, and a driving body rotatable with respect to the pump body about a first axis of rotation. The external rotor is constrained to the driving body. An idle shaft is rotatably connected to the pump body about a second axis of rotation parallel and eccentric to the first axis of rotation. The external rotor rotates about the first axis of rotation and is rotated by the driving body. The driving body is rotated by a motor. The internal rotor is fitted onto the idle shaft for rotating about the second axis of rotation and is rotated by the external rotor.

Abstract: An automotive vacuum pump includes a housing arrangement which encloses a pumping chamber and which rotatably supports a pump rotor having a rotor body with a bearing section and a vane section. The vane section of the rotor body has a vane slit. A slidable pump vane is supported in the vane slit. The slidable pump vane separates the pumping chamber into a plurality of rotating pumping compartments. The housing arrangement has a pumping chamber gas inlet opening and a pumping chamber gas outlet opening.

Abstract: A vacuum pump for a motor vehicle engine which has a stator and a chamber, has a side wall, and the side wall has a transversal section with a predetermined shape. The rotor mounted in the chamber is capable of rotating around a rotation axis parallel to the side wall. The vane mounted on the rotor is free to slide in a direction at right angles with respect to the rotation axis of the rotor, and the vane has a predetermined length and two opposite end portions that substantially slide along the side wall of the chamber. At least one of the end portions of the vane has at least one part that has a bend radius substantially equal to that of a part of the side wall, when the one vane is at a reference operating position.

Abstract: A receiver for acquiring a signal through a propagation channel, the receiver comprising channel estimating means (200) for producing stream of CIR estimates for the channel, a plurality of doppler filtering means (201) for filtering the CIR stream in parallel and selecting means (202) for selecting the output of one of the doppler filtering means for use in recovering said signal.

Abstract: A method of producing soft decisions for a signal, wherein a model provides an expression for an LLR for the signal, the LLR expression is dependent on noise power in the signal and can be rendered in a form independent of the noise power, wherein the method comprises evaluating the noise power independent expression using values from the signal to produce soft decisions, calculating a weight expressing the noise power affecting a soft decision relative to the noise power affecting at least one other soft decision and applying the weight to its respective soft decision.
