Abstract: A recirculating-ball steering system for transmitting a steering movement to a steering arm, includes: a housing having a steering piston arranged inside the housing, wherein the steering piston includes a ball screw drive and is displaceable along its longitudinal axis, and an electrical actuator for assisting the movement of the steering piston. Also described is a vehicle having the recirculating-ball steering system.

Abstract: Please substitute the new Abstract submitted herewith for the original Abstract: A recirculating ball steering gear for a steering system of a vehicle, in particular a utility vehicle, includes at least one housing, at least one steering spindle, at least one steering spindle nut which is guided in an axially displaceable manner inside the housing and which in the assembled state is connected to the steering spindle via a plurality of balls, and at least one bearing device, by which the steering spindle is supported in the housing. The bearing device, the steering spindle and the housing form an adjusted bearing arrangement.

Abstract: An electromechanical dual steering system for a utility vehicle includes two steering systems, each having a drive unit for actuating one steering linkage each for wheels of the utility vehicle. Each drive unit has an electric motor. The dual steering system has a main power supply for supplying the electric motors with energy. The electromechanical dual steering system is characterized in that the dual steering system has at least one emergency power supply for supplying at least one electric motor with energy in the event that the main power supply fails.

Abstract: A method and system of magnetic fingerprinting for mobile device indoor navigation and positioning. The method, executed in a processor of a server computing device, comprises generating a magnetic infrastructure profile of at least a portion of the indoor area; determining, in the processor, a magnetic field profile based on the magnetic infrastructure profile; and generating an association of magnetic field profile parameters associated with respective locations within the indoor area as the magnetic fingerprint map.

Abstract: A controller for controlling an apparatus comprising a blood pump, oxygenator, and blood filtering system connected together by blood flow tubing and to a patient to circulate blood from the patient through the apparatus and back to the patient, to oxygenate and filter the blood, the controller comprising at least one communication interface operable to receive signals generated responsive to monitored parameters characterizing blood flow and/or quality of blood from the patient circulating through the apparatus and configured to: determine values for the monitored parameters based on the monitoring signals; determine whether or not a value determined for a given monitored parameter for blood circulating through the apparatus is within a normative range for the parameter; and generate an alarm to alert an operator of the system if the value is not within the normative range.

Abstract: Embodiments of the present disclosure relate to methods and systems of updating an orientation of a mobile device in a global reference frame. The method includes gathering mobile device gyroscope data, gathering mobile device accelerometer data, gathering mobile device magnetometer data, determining a first orientation of the mobile device based on the gyroscope data, determining a second orientation of the mobile device based on the device accelerometer data and the device magnetometer data, determining a trust factor associated with the second orientation, and updating the orientation of the mobile device based on the first orientation, the second orientation, and the trust factor.

Abstract: A steering rack housing (20, 100, 100?, 100?) for a power steering system that surrounds a steering rack in a tubular manner and includes a hydraulic region (32), a mechanical region (34), and as an inner supporting bearing (38), wherein the supporting bearing is held in the steering rack housing (20, 100, 100?, 100?) by at least two cross-sectional contractions (46) of the housing.

Abstract: The invention relates to a slide vane (20) for a hydraulic power steering of automotive vehicles with a tubular control sleeve (24). Said control sleeve is connected to an output shaft (28) and comprises first control grooves (32) in its inner surface (34). Further, there is provided a tubular sliding sleeve (26) that is disposed at least in portions within said control sleeve (24). On its outer surface (38), the sliding sleeve (26) comprises second control grooves (36) that may be brought to coincide with the first control grooves (32) of the control sleeve (24), said first control grooves (32) being disposed substantially in the circumferential direction of the tubular control sleeve (24) and said second control grooves (36) substantially in the circumferential direction of said tubular sliding sleeve (26). The relative position of said control sleeve (24) and of said sliding sleeve (26) being relatively variable in the axial direction.
