摘要:
A communication device having an antenna tuned by a tank network at its input port to realize dual-band resonance. The antenna alone has a wideband but weak resonance, while the device antenna circuit with the tank network has a narrowband resonance between the two desired frequencies when the antenna is open-circuited. Together, the device antenna circuit with the tank network and antenna realize dual narrowband resonance at the two desired frequencies.

A devices for pumping fuel has at least one suction jet pump and a drive line, supplying the suction jet pump with fuel, that branches off from a pressure line leading to an internal combustion engine and that can be blocked off by means of a shutoff valve. By means of a shutoff valve, it is possible to switch off the suction jet pumps. The pressure of the pressure line acts on the shutoff valve in such a way that the shutoff valve closes at a pressure that is greater than or equal to a predetermined closing pressure.

One implementation provides a method for accessing a window previously viewed by a user in a graphical user interface (GUI) during an interaction with an individual. The method includes displaying to the user a first window in the GUI. The first window contains a collapsible/expandable menu. The menu contains an entry that refers to a window previously viewed by the user. Upon selection of the entry in the menu, the method further includes displaying to the user the corresponding window previously viewed by the user in the GUI. The corresponding window has a data-entry field that contains a latest version of information that is related to the interaction with the individual that was previously entered or modified by the user.
摘要:
The unit includes an electric drive motor (12) and a pump section (24) that are situated next to each other in a common housing (10) designed at least nearly in the shape of a hollow cylinder. The pump section (24) comprises a delivery element (26) rotating in a pump chamber (30), and one wall (32, 34) each forms a boundary of the pump chamber (30) with the drive motor (12) and with the outside of the housing (10) in the direction of the axis of rotation (28) of the delivery element (26). The walls (34) forming the boundary of the pump chamber (30) with the outside of the housing (10) is formed as a single component with the housing (10), and the walls (32) forming the boundary of the pump chamber (30) with the drive motor (12) is inserted into the housing (10) as a separate component. Due to the fact that the wall (34) forming the boundary of the pump chamber (30) with the outside is integrated with the housing (10), no separate steps are required to manufacture and assemble said wall and housing, and the pump chamber (30) is sealed off completely from the outside of the housing (10), because no joints are present that would have to be sealed off.

An electric-motor-driven housing for a feed pump (1), in particular for a feeding device for fuel, is proposed in which on the commutator side there is a connection cap (5) for the electrical connection contacts (3, 4) and pump inlets and/or outlets (6). The connection cap (5) comprises an electrically conductive plastic, and a connection to a ground potential can be established via an electrically conductive connection. The surface resistance of the connection cap (5) is designed such that a diversion of electrostatic discharge to the ground potential, with attendant shielding from electromagnetic radiation, ensues, and a predeterminable short-circuit current between the electrical connection contacts (3, 4) located directly on the connection cap (5) is not exceeded.
摘要:
A mold to produce fiber composite components is described where a fiber ply with matrix material (matrix material/resin) is saturated. The mold consists of a lower mold and an upper mold which is placed on top of the lower mold with intermediate fiber ply. The lower mold and upper mold have a contour matching each other and for the desired fiber composite component. The upper mold and the lower mold are made of a flexible material.

摘要:
The check valve according to the invention significantly reduces the generation of noise by producing an asymmetrical circulation around the closing body causing a force resulting from the flow and acting on the closing body to have a transverse component in relation to the opening direction, as a result of which increased friction and damping are generated in the closing body guide. The closing body may be asymmetrically embodied, or the housing wall encompassing the closing body may be provided with a conduit extending in the opening direction over at least a part of the travel path of the closing body.

A graphical user interface (GUI) tool for maintaining categorization schemes includes a categorization area that displays user-input fields which may be used to define a number of categories and a number of links that form a categorization scheme. The categorization scheme is organized to enable the computer-executed process to categorize the data. The categorization causes the selection of categories that correspond to the data. The selection is made by making a category determination beginning at the top level and proceeding to the children of categories that correspond to the data.
摘要:
A fuel pump has a pump housing, and a rotor rotatable in the pump housing and having an outer surface. The housing has an inner wall which faces the rotor and forms with the outer surface of the rotor a narrow gap. The inner wall is provided with a plurality of depressions which are independent from one another and form a sealing region.
