Abstract: Systems and methods for using models to optimize suggestions for long-term and short-term goals are disclosed. In one aspect, a method may include receiving input data associated with promotion of a product to one or more target entities, and defining a plurality of temporal goals for attainment based at least in part on the input data. The plurality of temporal goals may be classified into at least two categories of different timescales. The method may further include providing the plurality of temporal goals and a set of constraints to an optimization model comprising an objective function, and using the optimization model to generate a set of multi-dimensional actions with predicted action values for at least a subset of the plurality of channels. The predicted action values can collectively maximize an impact value of the objective function while balancing a feasibility of the plurality of temporal goals with respect to one another.

Abstract: A system for coupling a first train coach to a second coach includes a first automatic coupler mountable at an end of the first coach, providing for a mechanical coupling to a second automatic coupler mountable at the second coach. The first coupler has a first coupling actuator that drives a first locking mechanism between locked and unlocked states. A first bellows has a first mounting frame, first coupling frame, and first latching mechanism at the first coupling frame. The first coupling frame is coupled by the first latching mechanism to a second coupling frame of the second bellows. A controller receives an uncoupling instruction, generates an uncoupling signal and sends it to the first coupling actuator, receives a coupling instruction, and generates a coupling signal and sends it to the first coupling actuator.

Abstract: A lidar device having an integrated optics that has a beam deflecting unit having an optical phase array that has a multiplicity of antennas that are set up to emit electromagnetic radiation at a prespecified angle of radiation. The angle of radiation covers a prespecified field of view of the lidar device. The angle of radiation has a first angle of radiation subregion, in which electromagnetic radiation is emitted having a polarization A, and has a second angle of radiation subregion, in which electromagnetic radiation is emitted having a polarization B.

Abstract: A telescoping jib of a mobile crane having a basic box and a plurality of inner boxes that can each be extended from a retraction position to an extension position and that can be locked and unlocked together in the respective retraction position or extension positions by means of bolting holes, which are arranged in the basic and inner boxes, and associated locking bolts. In order to provide a telescoping jib of a mobile crane which can be easily unlocked in an emergency, it is proposed that, in the retraction position of the basic and inner boxes, the bolting holes for the extension positions are aligned with one another.

Abstract: A telescoping jib system of a mobile crane having a basic telescoping jib and an additional telescoping jib that can be retracted and extended via a telescoping cylinder with a securing and locking unit. In order to improve the telescoping jib system, it is proposed that a securing unit is arranged on a tip of the telescoping cylinder, the securing unit comprises exclusively at least one driving bolt, via which an additional telescoping jib separate from the basic telescoping jib can be retracted into the basic telescoping jib. The invention also relates to a method for lengthening a basic telescoping jib of a mobile crane by means of an additional telescoping jib to form a telescoping jib system.
