The transporting system for items of luggage comprises a rolling mechanism (10) and at least one item of luggage or case element (20), the rolling mechanism (10) having a wheel arrangement (11), a pulling device (12) and fastening means (13) for releasably connecting the item of luggage (20) to the rolling mechanism, and is characterized in that the fastening means (13), on the one hand, are connected to the rolling mechanism and, on the other hand, can be fixed in a releasable manner in an interior of the item of luggage (20). The fastening means may comprise, for example, touch-and-close fastener strips (13) which can be introduced into the interior of the item of luggage through slots (22) made in a rear wall (21) of the item of luggage (20), and can be fixed there on a touch-and-close fastener strip.

Abstract: A method is described for measuring a value of a driver quantity of a system, to which a number of system quantities are assigned, each system quantity being assigned at least one property and at least one value, the value of the driver quantity being computed under consideration of the at least one value of the defined system quantities which, on the basis of their at least one property, meet at least one condition. The driver quantity is thus clearly defined yet may be a function of any number of system quantities within the system. Using the driver quantity, a certain aspect within the system may be detected either statically or dynamically, i.e., as a function of time. On this basis statistics may be generated. In addition, this method opens up possibilities for interpretation.

Abstract: A method for predicting a development over time of a system quantity (WP, 41, 42, 43, 44, 6) of a system (2), to which a number of system quantities (WP, 41, 42, 43, 44, 6) are assigned, a sequence of one of the system quantities (WP, 41, 42, 43, 44, 6) in each case being characterized by at least one event, wherein a delay of the at least one event is detected. On this basis, at least one actual value (I) over time for at least one event of at least one system quantity (WP, 41, 42, 43, 44, 6) is calculated within one measurement period to be predicted. The present invention makes it possible to provide a prediction of the system (2) or of one or a plurality of system quantities (WP, 41, 42, 43, 44, 6) based on flexible measurement periods. A future development of the system (2) or of the at least one system quantity (WP, 41, 42, 43, 44, 6) may not only be estimated roughly but instead may be calculated reliably under consideration of measurable data.

Abstract: Method of simulating the performance of a vehicle on a roadway on a power train test bed with the help of torque-controlled electric load machines mounted on the shafts of the power train of the vehicle and with the help of a computer with a vehicle model stored therein and a tire model simulating the slip-dependent friction, in which method the angular wheel speed is measured on at least one of the shafts, and the tire model determines a force transmitted from the tire to the roadway at this angular wheel speed on the basis of the tire model using a vehicle velocity and a tire normal force, and it also determines a setpoint torque for this force for the torque-controlled load machine mounted on this shaft, in such a way that a difference corresponding to the actual slip is established between the measured angular wheel speed and a nominal angular wheel speed value corresponding to the vehicle velocity used in the tire model and calculated in the vehicle model with feedback of the force transferred to the roa

Abstract: Luggage, including a central part formed two mechanically strong, mutually linked half-frames that support two trays defining the central space of the luggage. A connecting frame (40) is mounted between each half-frame and an associated tray and is fitted with a channel (41) within which the tray is affixed by appropriate fasteners. Using the same central parts and connecting frames, a plurality of diverse suitcases or briefcases may be implemented using other trays such as soft trays and.as a result manufacturing costs may be lowered.

Abstract: A silicon wafer with a thickness of the order of magnitude of 0.8 mm is firstly processed at least partially on a first side. The unthinned silicon wafer is subsequently provided, on the second side, with a second circuit structure and a metallization structure arranged above the latter. The electrical insulation of the two circuit structures is effected solely by the intermediate undoped silicon material of the wafer. The two metallization structures are connected to an external contact-making structure.

Abstract: The invention relates to a suitcase with interchangeable case-shells, the central part of which (10) includes two stable half-frames (20, 30) bearing one against the other. Said half-frames (20, 30) are used as supports for the two case-shells (41, 42) of the suitcase. Each shell is detachably connected to the half-frame (20, 30) assigned to it. In order to ensure mutual support of the load, each shell (41, 42; 51, 52) edge is extended, at least in partial portions, by a flange (43, 44) the length of which is chosen so as to ensure that, when the suitcase is closed, the flange of the first shell (41; 51) and the flange (44) of the second shell (42; 52) abut against each other.

Abstract: A carrying case comprises an octagonal shaped body fitted with an octagonal shaped lid, a trapezoidal shaped compartment being located on an octagonal shaped surface of the octagonal shaped lid. The compartment is fitted with a trapezoidal shaped lid.
