  • Patent number: 11428033
    Abstract: A pre-assembled fitting group for a window or door has a drive rod portion, which is movable in the rebate circumferential direction, a first control element, and a second control element which is arranged on a cross slide. The first and the second control elements cooperate and are coordinated with one another in such a way that a displacement of the first control element by the drive rod portion causes a displacement of the cross slide. A guide part that can be fixedly mounted on the sash, wherein the cross slide is at least partially movable relative to the guide part.

  • Publication number: 20220015718
    Abstract: In an approach to non-invasive blood pressure measurements, a blood pressure measurement system receives a pulse curve signal representing a sequence of pulse curves of a subject from a pressure cuff. The blood pressure measurement system applies a weighting function that applies one or more weights to a pulse curve of the sequence of pulse curves to obtain a weighted pulse curve and the one or more non-constant clamp pressure signals are a weighting function input parameter. The blood pressure measurement system sums at least the weighted pulse curve and a second weighted pulse curve, which approximates a shape and an amplitude of a pulse wave of the subject. The blood pressure measurement system determines a health status of the subject based on the pulse wave and generates a graphical representation of the pulse wave of the subject and the health status of the subject.

  • Patent number: 9630650
    Abstract: A device for adjusting camber and/or toe of a vehicle wheel includes a rotatable actuating element arranged between a wheel-side carrier part of a wheel carrier and an axle-side guide part thereof and adjustable by a rotary drive unit. A double-acting freewheel is disposed in a driving path between the rotary drive unit and the actuating element and configured to assume a release position in which the driving path is enabled for transmission of a driving torque from the rotary drive unit onto the actuating element, and to assume a locking position in which a locking torque is generated in opposition to a reaction torque directed from the actuating element to the rotary drive unit. The freewheel is constructed to open in the presence of the driving torque generated by the rotary drive unit and closes in the presence of the reaction torque generated by the actuating element.

  • Patent number: 9475519
    Abstract: A steering stop for a steer-by-wire steering system, includes a steering shaft for functionally connecting to a steering wheel, wherein a pressure chamber is provided for each direction of rotation of the steering shaft. A rotation of the steering shaft produces a reduction in the volume of a corresponding pressure chamber, and the steering stop also comprises a hydraulic valve such that resistance against a further rotation of the steering shaft is generated by the operation of said hydraulic valve when predetermined environmental conditions are met.

  • Patent number: 9452725
    Abstract: An occupant protection device for a vehicle includes an airbag module arranged in a hub region of a vehicle steering wheel used for steering vehicle wheels about a steering angle when the steering wheel is turned to a rotary position. The airbag module has an airbag configured for deployment between a driver and the steering wheel in the event of a crash. An adjustment unit is provided to turn the steering wheel from the rotary position to a crash position while the steering angle of the vehicle wheels remains unchanged so as to align the airbag with a posture of the driver in the event of a crash.
