Abstract: Indices or data structures used by an enterprise search system are stored across heterogenous storage devices. One or more characteristics associated with a data structure and one or more characteristics associated with a search query operator supported by the data structure are considered when determining which storage device should store each data structure.

Abstract: The present invention relates to a fuel system as well as a method for controlling the same. More specifically, it relates to a fuel system of motor vehicles adapted to be powered by alcohol-containing fuels, and specifically by alcohol-containing fuels and by petrol, so-called Flexible Fuel Vehicles (FFV). These vehicles can be powered by fuels with varying alcohol content, and also by pure petrol. The fuel system according to the invention comprises a main tank (1) for fuel, a cold-start tank (2) with fuel which is sufficiently inflammable to be used in connection with cold starts, as well as fuel line system connecting these tanks to each other and to injection means of the engine of the vehicle, where at least one pump (8, 13) is adapted to transfer fuel through the fuel line system. Specifically, the invention relates to a system which is controlled so that fuel is transferred from the main tank (1) to the cold-start tank (2) when the alcohol content of the fuel is below a predetermined threshold value.

Abstract: An assembly, a method and a motor vehicle for cleaning ambient air in the vicinity of an internal combustion engine (102) having combustion air inlet means (103) and energy emitting means (104)are disclosed. The assembly (101) further includes adsorbent means (105) for adsorbing at least one pollutant when in a first mode of operation and for desorbing the pollutant when in a second mode of operation. The adsorbent means have an inlet (106) for polluted ambient air (107, 107′) and an outlet (108) for cleaned ambient air (109, 109′). Furthermore, the assembly (101) includes a pollutant conduit (110) through which the desorbed pollutant is transferred from the adsorbent means (105) to the combustion air inlet means (103) when in the second mode of operation, and the adsorbent means (105) are arranged for being brought into the second mode of operation by means of energy supplied from the energy emitting means (104).

Abstract: Apparatus is disclosed for venting a fuel tank including a canister containing an absorbent for fuel fumes, a sensor for detecting the filling of the fuel tank and emitting a signal based thereon, a first connection line for connecting the canister with the fuel tank and having a sufficient size to permit the free flow of gases from the fuel tank during filling of the fuel tank, the first connection line including a first valve operable between an open position and a closed position, the first valve normally being in the closed position and being actuatable into the open position by the signal thereby permitting the free flow of gas from the fuel tank through the first connection line during filling, a second connection line for connecting the canister with the fuel tank and connected to the first connection line between the first valve and the canister, the second connection line including a second valve including at least one restrictor for substantially limiting the flow of gases therethrough as compared t
