Embodiments relate to determining a speed of a multidimensional motion of an athlete in a global coordinate system based on multidimensional acceleration data from a multidimensional accelerometer placed at a movable limb of the athlete, the movable limb being at least one of translatory and rotatable, and the movable limb defining a local coordinate system. Based on the multidimensional acceleration data, at least one correction quantity may be determined taking into account a rotation of the local coordinate system relative to the global coordinate system during the multidimensional motion. The speed of the multidimensional motion may be determined based on an integration of the multidimensional acceleration data and in consideration of the at least one correction quantity.

The invention relates to a process for continuously preparing one or more olefins from an aqueous solution of the corresponding alcohol(s), comprising the steps of: - providing a solids-free aqueous solution of the alcohol(s), - conducting this solution through a reactor filled with a fixed bed catalyst in such a way that the solution comes into contact with the catalyst as it flows through the reactor, at a temperature of at least 300°C and a pressure of at least 220°C in such a temperature-pressure combination that the alcohol(s) is/are converted under supercritical conditions, and - transferring the biphasic mixture formed to a separator in which the mixture is separated into a crude olefin gas phase and an aqueous liquid phase, - where the catalyst is selected from metal oxides having the properties of a Brønsted acid, insoluble metal or semimetal phosphates and porous materials selected from pumice and charcoal, the surface of which has been covered with inorganic acid groups. The process is especially suitable for aqueous solutions having a high water content. It can be performed advantageously using continuously operated reactor systems.

Die Erfindung betrift ein Verfahren zur Bestimmung der Schichtdicken eines Schichten aufweisenden Prüfkörpers (4), mit einer äußeren Deckschicht (1) und einer im Prüfkörper angeordneten Basisschicht (2), wobei die Deckschicht und die Basisschicht unterschiedliche magnetische Eigenschaften und Stoffzusammensetzung aufweisen mit den Verfahrensschritten: - Erzeugen eines magnetischen Wechselfeldes; - Messen der magnetischen Feldstärke; - Messen des Oberwellengehalts des Zeitsignals der tangentialen Magnetfeldstärke in Abhängigkeit von der magnetischen Feldstärke; - Messen der Überlagerungspermeabilität in Abhängigkeit von der magnetischen Feldstärke und - Bestimmen der Schichtdicke zumindest einer der Schichten durch ein statistisches Analyseverfahren, auf Basis der gemessenen Werte des Oberwellengehalts des Zeitsignals der tangentialen Magnetfeldstärke und der Überlagerungspermeabilität. Des Weiteren betrifft die Erfindung eine Vorrichtung geeignet zur Durchführung des Verfahrens und die Verwendung der Vorrichtung zur Bestimmung der Schichtdicken eines Prüfkörpers (4), wobei zumindest eine der Schichten (1), (2), (3) des Prüfkörpers (4), insbesondere die Deckschicht (1) paramagnetisch oder diamagnetisch ist.
摘要:
What is described is a cleanroom arrangement with a housing that separates from the surroundings a space which immediately or indirectly adjoins a floor region, with a mobile filter-ventilator unit which has an air inlet region and an air outlet region and is arranged in the surroundings outside the space, and with a supply line connecting the air outlet region and the space bounded by the housing. The invention is characterized in that the housing is a tent-like shell wall arrangement which encloses the space in a dome-like and uninterrupted fashion and which comprises a flexible, folding shell wall that directly faces the space and is made exclusively of at least one cleanroom-compatible material and comprises at least one support element that rests on the floor region and/or at least one hanging arrangement provided on the shell wall; in that the at least one cleanroom-compatible material is suitable for directly bounding a cleanroom of ISO classes 1 to 9 according to DIN ISO/FDIS 14644-1:2015-08; in that the shell wall is spaced apart from the floor region at least in certain sections, or provides, indirectly or directly adjoining the floor region, at least one opening in the shell wall or at least one shell wall section with a higher air permeability than in the rest of the shell wall, for the controlled outflow of air from the space region into the surroundings; and in that the mobile filter-ventilator unit is designed to provide, from ambient air, ultrapure air in accordance with the above standard, and the supply line is produced as a hollow duct made of cleanroom-compatible material in accordance with the above standard, which discharges into the space at an upper shell wall region so as to establish, within the space, a vertical, downward-oriented flow of pure air which exits the space in a controlled manner close to the floor region.

The invention relates to a device for the force-assisted lifting of an inclined upper body of a person (P), comprising a shoulder part (1) that can be removably fixed in a secure manner to the shoulder area of the person as well as a hip part (2) which can be removably fixed in a secure manner to the hip area of the person, both being connected by an arrangement (4) comprising a plurality of serially arranged vertebral bodies (5) which are guided along at least a strand-like, elastic or elastically mounted traction element (6) which is connected at each end to the shoulder part (1) and the hip part (2). At least two adjacent vertebral bodies (5) have each at least one surface area (53, 54) which is designed to have a matching contour. The invention is characterized in that, for the purpose of mutual contacting, the at least two vertebral bodies (5) are assembled directly by the surface areas (53, 54), which have a matching contour, and exclusively by means of the at least one traction element (6) while being mutually subjected to an elastic force, in a loose and a self-centering manner relative to one another, and in that the surface areas (53, 54) having a matching contour are spherical and the traction element (6) has an elastic configuration or is mechanically coupled to at least one elastic element.
