A microfluidic, chip-based assay device has been developed for measuring physical properties of an analyte (particularly, whole blood or whole blood derivatives).

Axial adjustment device (1), comprising a first disk (2) which is rotatable and axially displaceable both in a first circumferential direction (I) and in a second circumferential direction (II), namely a circumferential direction counter to the first circumferential direction (I), and a second disk (3) which is locked against rotation in the first circumferential direction (I) and is rotatable in the second circumferential direction, wherein the second disk (3) has an activating element (8) on its end side facing away from the first disk (2), and wherein the first disk (2) and the second disk (3) each have, on their mutually facing end surfaces, at least three identically formed depressions (4) which lie opposite one another in each case in pairs and thus form at least three pairs of depressions, wherein a rolling element (5) is arranged in each of the pairs of depressions, wherein the depressions (4) each have a slope in the first circumferential direction (I) from a lower dead centre (6) towards an upper dead centre (7), and an actuation arrangement, comprising such an axial adjustment device.
US11852237B2 Electromechanical actuator for generating an axial actuating force
An electro-mechanical actuator for generating an axial actuation force is provided. The electro-mechanical actuator includes an electric machine having a stator (1) and a rotor (2). The electro-mechanical actuator also includes a spindle drive with a rotary element (6) and with an element that is movable in a translatory manner. A rotation of the rotary element (6) may result in a translatory motion of the element that is movable in a translatory manner. The rotor (2) and the rotary element (6) of the spindle drive are coupled to each other in a circumferential direction (U) such that a rotation of the rotor (2) results in a rotation of the rotary element (6) of the spindle drive (5). A rotational play (8) is formed between the rotor (2) and the rotary element (6) of the spindle drive in the circumferential direction (U).
