Abstract: A machine tool (10) for machining workpieces (18) has a main spindle (12) which carries a tool holder (14) at its end and is mounted in such a way that it can rotate about an axis of rotation (22) and can move along the axis of rotation (22). A preferably electromagnetic feed device (32) is also provided, which exerts a force (FZ) acting along the axis of rotation s on the main spindle (12). A screw gear (52), which connects a drive (20) for driving the main spindle to the main spindle (12), drives the main spindle (12) in rotation and simultaneously moves it along the axis of rotation (22). The screw-and-nut gearing (52) has a thread (64, 66a, 66b) formed on a first component (54) and a cam (70a, 70b) formed on a second component (12) that cooperates with the thread (64, 66a, 66b). One of the two components (54) is rotated by the drive (20) via a drive gear (57) and is immovably mounted along the axis of rotation (22). The other of the two components is the main spindle (12).

Abstract: A sealing plug profile for fitting to an arrangement for a vehicle roof has a sealing element and a baseboard which is coupled to the sealing element and which extends along a longitudinal axis (LF). The baseboard may have a first base hollow space and a second base hollow space and a central web which separates the first and the second base hollow space from each other in a predetermined manner so that the first and the second base hollow space form two mutually separate hollow spaces within the baseboard, which are each delimited in a predetermined manner along the longitudinal axis (LF) by the central web and an edge of the baseboard.

Abstract: A method for starting a system-on-a-chip, SoC, without read only memory, ROM, comprises the steps of receiving, by a processor comprised by the SoC, a reset signal, monitoring, by a monitoring component comprised by the SoC, a connection between the processor and at least a non-volatile memory, both comprised by the SoC, upon occurrence of a first read access of the processor to the non-volatile memory via the connection checking, by the monitoring component, whether a data value returned in response to the first read access via the connection conforms to a pre-set value, and if the returned data value differs from the pre-set value, stopping, by the monitoring component, operation of the processor.

Abstract: Methods for treating hypertension and associated systems and methods are disclosed herein. One aspect of the present technology, for example, is directed to methods for therapeutic renal neuromodulation that partially inhibit sympathetic neural activity in renal nerves proximate a renal blood vessel of a human patient having a 24-hour heart rate at or above a median heart rate for a population of hypertensive patients. This reduction in sympathetic neural activity is expected to therapeutically treat one or more conditions associated with hypertension of the patient. Renal sympathetic nerve activity can be modulated, for example, using an intravascularly positioned catheter carrying a neuromodulation assembly, e.g., a neuromodulation assembly configured to use electrically-induced, thermally-induced, and/or chemically-induced approaches to modulate the renal nerves.

Abstract: The invention relates to an input circuit arrangement (11), which is designed for operation either in a first or a second operating mode (A, B) and comprises a connection (13) for supplying a connection signal (SWI) and a detection circuit (14). The detection circuit (14) is coupled on the input side to the connection (13) and is designed to put the input circuit arrangement (11) into an operating mode from a group comprising the first and second operating modes (A, B) depending on the steepness of a change of the connection signal (SWI).

Furthermore, a method for providing a current is described.

Abstract: The present invention relates to a graphical user interface for a system that compiles MATLAB models for synthesis into register transfer level code. The graphical user interface provides a visual representation of the design in a manner that allows the user to more easily understand the algorithm being modeled. From this interface, the user may also modify the type, size and dimensions of variables from dialog boxes. The system allows the user to efficiently compare and verify a fixed-point design versus the MATLAB design. The interface allows the user to then make further changes to the design, or synthesize the design into a register transfer level file.
