Abstract: A piston accumulator has an accumulator housing and a separating piston (8) guided for longitudinal motion in the accumulator housing. The separating piston separates a liquid side (4) from a gas side (10) in the accumulator housing. Liquid unintentionally transitions from the liquid side (4) to the gas side (10) despite a piston seal on the separating piston (8). By a return device (28), the transitioned liquid is at least partially returned from the gas side (10) of the accumulator housing to the liquid side (4) of the accumulator housing.

Abstract: A bicycle helmet adapted to be used with eyewear includes an impact-absorbing body, a resilient wiper, and an alignment feature. The impact-absorbing body has a convex exterior surface and a concave interior surface adapted to be positioned on a user's head. The impact-absorbing body further includes an aperture formed in the exterior surface and dimensioned to permit insertion of a portion of the eyewear into the aperture along an insertion axis. The resilient wiper is positioned at least partially in the aperture and arranged to engage the portion of the eyewear upon insertion into the aperture. The alignment feature defines at least a portion of the aperture and is oriented to guide the portion of the eyewear toward the resilient wiper.

Abstract: A method for fabricating an xMR magnetic field sensor with at least one xMR sensor element from a workpiece containing an xMR multilayer system, including a magnetically hard reference layer with a reference magnetization direction. The method involves a programming operation to set or modify the reference magnetization direction in a sensor region by locally heating the reference layer beyond a threshold temperature using laser radiation, exposing the heated region to an external magnetic field to set the reference magnetization direction, and subsequently cooling the region. The laser processing operation employs a mask projection technique, where a mask with at least one aperture is irradiated with laser pulses, and the fully illuminated aperture region is imaged onto the processing plane using an imaging lens.

Abstract: Methods, systems, and computer storage media for providing financial data analytics recommendations using a data analytics engine in a customer relationship management system. The recommendations can be a lead that is information associated with a model-generated suggested consumer solution, an alert of increased risk of attrition, or an alert of increased risk of default. The data analytics engine is configured to generate target variables associated with financial products or the customer relationship and utilize modeling techniques and apply rules to generate recommendations. Operationally, the recommendations are generated based on a data analytics model. Generating the recommendations is based on feature variables that are generated based on aggregation and transformation of customer data and utilizing machine learning models to detect patterns in the customer data using the feature variables.

Abstract: A hydropneumatic piston accumulator has an accumulator housing (1) defining a housing longitudinal axis (11) and a piston (9) longitudinally movable between two housing covers (5, 7) positioned opposite each other. In the housing (1), the piston (9) separates a working chamber (13) for a compressible medium, such as a working gas, from a working chamber (15) for an incompressible medium, such as hydraulic fluid. A piston part (55) of a displacement measurement device continuously determines each position of the piston (9) in the housing (1). A rod-shaped guide (29, 57) is stationarily positioned in the accumulator housing (1) and passes all the way through the piston (9) in each of its displacement positions in the accumulator housing (1). The piston (9) is movably guided along the guide until it reaches the stop on one of the two housing covers (5, 7) and is sealed against this guide (29,57) using a sealing device (49, 50).
