A system comprises a device (300) for receiving and transporting objects and a generator (402). The device (300) has an adjusting mechanism (305, 306) and a base (304) that can be adjusted in height by means of the adjusting mechanism (305, 306). The adjusting mechanism (305, 306) is designed in such a way that the base (304) can be lowered by a weight of objects received. The adjusting mechanism (305, 306) is also able to be connected or is connected to the generator (402) in such a way that the generator (402) is driven and converts mechanical energy into electrical energy while the base (304) is being lowered.

For an identification of packing units, data resulting from an optical recording of at least one surface of a packing unit undergo a text recognition to recognize individual characters. A plurality of characteristic values is determined, each characteristic value being based on another predetermined statistical analysis of the recognized characters. The plurality of characteristic values forms at least one part of an identification of the packing unit. The characteristic values are provided for storage and/or for comparison with previously stored characteristic values.

The invention relates to a method which comprises determining first geometry information of a first object stream of a plurality of objects, which are transported on a first conveyor. The method also comprises determining second geometry information of a second object stream of a plurality of objects which are transported on a second conveyor. The first conveyor is configured to transport objects at a first speed, and the second conveyor is configured to transport objects at a second speed. The first conveyor and the second conveyor are arranged in such a way that the objects which are transported by the first conveyor move onto the second conveyor. The method also comprises adjusting the first speed of the first conveyor and/or adjusting the second speed of the second conveyor on the basis of the determined first geometry information and/or the determined second geometry information.

In a device and a method for increasing the safety of a motor vehicle, a first sensor unit (2) detects the environment, in particular free spaces and objects (0) and the position and motion thereof, a second sensor unit (20) detects the environment state, a third sensor unit (30) detects the vehicle state, and a fourth sensor unit (40) detects the driver inputs. The respective data from the several sensor units are combined. In consideration of the data, a driving safety coordinator (6) calculates the risk of collision on the basis of a risk evaluation, and determines pre-collision phases (P1, P2, P3, P4a, P4b) of the motor vehicle (1) with regard to the object (0).

The present invention relates to a method for the prediction and adaptation of movement trajectories of a motor vehicle for assisting the driver in his task of driving and/or for preventing a collision or reducing the consequences of an accident. The present invention further relates to a device for carrying out the method. According to the present invention and in order to carry out a prediction and adaptation of movement trajectories of a motor vehicle, an intersection of situatively required movement trajectories, which are determined using an environment sensor system, and physically possible movement trajectories, which result from properties which are characteristic of the driving dynamics of the motor vehicle and from the coefficient of friction obtained between tyres and road up to a maximum possible threshold coefficient of friction, is formed. According to the invention, only movement trajectories are taken into account which lie within this intersection. In this way, it is ensured that only movement trajectories are taken into account which, on the basis of the forces exerted on the wheels and resulting from the calculated movement trajectories by combining braking forces and/or steering forces, lie below the maximum possible threshold coefficient of friction.
摘要:
Calculations to be performed on a massive data set may be delegated to a plurality of local servers for parallel processing. Each local server advances through a subset of database objects to determine if the objects are relevant to the calculation. If so, the objects' data is used as an operand to the calculation to generate intermediate results at the local server. The intermediate results of the various local servers are transmitted to a central server, which generates final results and transmits them back to the local servers. The local servers write the final results into each object in its respective subset, where relevant. The method is efficient because each object in the database is opened at most twice. Opening and closing database objects often involve transfers from bulk storage and, therefore, are some of the most time-consuming operations that computer systems perform.

A device for connecting a generator to a belt drive of an internal combustion engine is provided, which includes a belt pulley (1) that is guided so that it can rotate relative to a hub (2) set on a shaft (3). At least one spring element is arranged between the belt pulley (1) and the hub (2) and connects the belt pulley (1) and the hub (2) to each other elastically for transferring rotational motion and here sets a relative rotation between the belt pulley (1) and the hub (2) corresponding to an effective torsional stiffness. The at least one spring element is placed with a defined movement play (s) with respect to the belt pulley (1) and/or the hub (2), in order to allow relative rotation through the movement play (s) in a first region (I) with a low torsional stiffness, while, in a second region (2), a high torsional stiffness can be generated by the at least one spring element.
