Abstract:
Die Erfindung betrifft eine Geschwindigkeitsüberwachungseinrichtung (41) zum Messen einer Drehzahl beziehungsweise Drehgeschwindigkeit einer Hauptantriebswelle (27) einer Personentransportanlage (1). Hierzu weist diese mindestens ein Drehzahlsensor (43) mit einer Eingangswelle (45), ein Ritzel (47), und eine Abgriffseinrichtung (49) auf, die so konfiguriert ist, dass sie auf einer Wellenmantelfläche (39) der Hauptantriebswelle (27) einer Personentransportanlage (1), deren Drehzahl gemessen werden soll, angeordnet werden kann. Des Weiteren ist eine Halterung (61) zur Befestigung des Drehzahlsensors (43) und des Ritzels (47) in einer ortsfesten Position relativ zu einer Drehachse der Abgriffseinrichtung (49) vorhanden, wobei die Abgriffseinrichtung (49) eine Verzahnung (53) aufweist, die mit dem Ritzel (47) drehübertragend koppelbar ist und das Ritzel (47) in der Halterung (61) in zwei Lagerstellen (55, 57) drehbar gelagert ist.
Abstract:
An apparatus and method for calculating athlete speed non invasively, on the field/court of play using data from a torso-mounted inertial measurement unit. The method complements existing, GPS-based methods for calculating athlete speed by enabling use in environments where GPS signal is unavailable (i.e. indoors).

Abstract:
The invention relates to measuring devices to be used in the measuring of angular velocity and, more precisely, to vibrating micromechanical sensors of angular velocity. In a sensor of angular velocity according to the invention, a mass is supported to the frame of the sensor component by means of an asymmetrical spring structure (1), (2), (3), (4), (22), (24) in such a way, that the coupling from one mode of motion to another, conveyed by the spring (1), (2), (3), (4), (22), (24), cancels or alleviates the coupling caused by the non-ideality due to the skewness in the springs or in their support. The structure of the sensor of angular velocity according to the invention enables reliable measuring with good performance, particularly in small vibrating micromechanical solutions for sensors of angular velocity.
Abstract:
A sensor arrangement (1; 20; 30; 40) is disclosed, for detection of forces, which might lead to a deformation of components, for example chassis components (10), in particular, on a motor vehicle, as a result of an accident. The sensor arrangement (1; 20; 30; 40) comprises a number of contact elements (2, 3, 4; 21, 22, 23; 31, 32, 33), which are staggered behind each other on the component (1), in a possible direction of deformation, with compressible insulation layers (5, 6, 7; 24, 25; 35, 36) lying between the contact elements (2, 3, 4; 21, 22, 23; 31, 32, 33). The contact elements (2, 3, 4; 21, 22, 23; 31, 32, 33) are connected in an electrically conducting manner to an electronic analytical unit, by means of which a breaking or a coming into contact of neighbouring contact elements (2, 3, 4; 21, 22, 23; 31, 32, 33) as a result of a deformation may be recorded, but may not be converted to a control and/or regulatory signal.
Abstract:
A golf-cart speedometer/odometer has a rotation-mark collar (1) on a cart-wheel rim (2) that signals rotation to a rotation sensor (4) on a housing extension (5) from a cart-axle housing (6). Measurement of rotation is communicated electrically from the rotation sensor to a readout console (8) having a speedometer (10), a resettable long-distance odometer (11) in metric or English and a resettable short-distance odometer (12) in metric or English readout. Rotation-marking is preferably with a plurality of four collar magnets (3) separated ninety degrees apart for a rotation sensor having a Hall-effect communication of passage of the four collar magnets. Optionally, the rotation-marking of the rotation-mark collar can utilize a plurality of four magnetic-material markers of a rotation-sensor magnet to decrease magnetic field that could damage computers or medical equipment in the vicinity. Further optional, the ratio-marking of the rotation-mark collar can utilize four mechanical trippers (31) and trippets (32).
