Abstract: The disclosure relates to a planetary roller screw drive comprising a threaded spindle nut, a horizontal threaded spindle, a plurality of planetary rolling elements having a planetary rolling element profile, and at least two planetary guide rings. The threaded spindle is arranged concentrically in the planetary guide rings and the spindle nut. The planetary guide rings can be rotated relative to the threaded spindle and the planetary rolling elements are mounted so as to be rotatable about their associated planetary rolling element axis in the planetary guide rings and inside the spindle nut. The planetary rolling element profile of the planetary rolling elements meshes with the threaded spindle. The planetary guide rings are connected to a housing case for conjoint rotation, and the housing case has a housing case lateral surface on which a toothing is formed for coupling in a geared manner to with a continuous traction mechanism.

Abstract: A vehicle hitching assistance system includes a controller executing an initial alignment process including searching for a trailer within a specified area of image data that is less than a total field of the image data in directions corresponding with both a longitudinal distance between the vehicle and the trailer and a lateral direction perpendicular to the longitudinal distance, presenting an indication to a driver of the vehicle to reposition the vehicle when the trailer is not identified within the specified area, and removing the indication when the trailer is identified within the specified area. The controller further executes an automated backing process upon identifying the trailer within the specified area, including identifying a coupler of the trailer and outputting a steering signal to the vehicle to cause the vehicle to steer to align a hitch ball of the vehicle with the coupler of the trailer during reversing.

Abstract: Systems, methods, and apparatuses for debriding a tissue site are described. The system includes a manifold and a cover adapted to form a sealed space over the tissue site for providing negative pressure. The system also includes a debridement tool positioned between the manifold and the tissue site. The debridement tool having a tissue-facing surface and a plurality of holes separated from each other by walls. The walls have transverse surfaces extending between the tissue-facing surface and an opposite surface that form cutting edges. The holes have a perforation shape factor that allows the holes to collapse from a relaxed position to a contracted position in response to the application and removal of negative pressure from the sealed space. The cutting edges debride the tissue site in response to movement between the relaxed position and the contracted position.

Abstract: A dental furnace for firing dental-ceramic compounds, comprising a combustion chamber for receiving ceramic elements to be fired. The heating of the combustion chamber is carried out using a heating device. The heating device is connected to an evaluation device via a resistance measuring device. The temperature in the combustion chamber and/or an operating state of the dental furnace can be determined using the evaluation device.

Abstract: Three-dimensional master equation modeling for disordered semiconductor devices is provided. Charge transport is modeled as incoherent hopping between localized molecular states, and recombination is modeled as a nearest-neighbor process where an electron at a first location and a hole at a second location can recombine at either the first location or the second location. Here the first and second locations are any pair of nearest neighbor locations. We have found that this nearest neighbor recombination model performs substantially better than the conventional local recombination model where an electron and a hole must be at the same location to recombine. The recombination rate is modeled as a product of a prefactor ?, hopping rates and state occupancies. Importantly, we have found that sufficient simulation accuracy can be obtained by taking ? to be given by an empirically derived analytic expression.

Abstract: The invention pertains to a system consisting of a first floor treatment apparatus that is exclusively guided manually within an environment by a user and a second floor treatment apparatus that is exclusively operated automatically, wherein the second floor treatment apparatus is designed for orienting and localizing itself within an environment. The first floor treatment apparatus is designed for detecting a movement path of the first floor treatment apparatus during a movement of the first floor treatment apparatus that is manually guided by a user, as well as for transmitting information on the detected movement path to the second floor treatment apparatus by means of wireless communication. The second floor treatment apparatus is designed for receiving the information and for autonomously traveling along the movement path within the environment based on the received information.
