Abstract: A combination measuring device for measuring the weight and a further body parameter of a subject includes a weighing scale, a measuring apparatus for the further body parameter, and a data acquisition and processing unit to control the measuring process of the scale and measuring apparatus. The device acquires from the scale measuring signals representing a weight as a function of time over a measuring period, processes the signals, and outputs measurement results. The data acquisition and processing unit determines a weight measuring result from the measuring signals of the scale; monitors over the measuring period a deviation of the measuring signals from the weight measuring result; and, in case the deviation exceeds a predetermined first threshold value, generates a suspicion message indicative of possible movement of the subject. The suspicion message is used in an examination of the reliability of the measuring result for the further body parameter.

Abstract: A railway train control system having a multi-purpose display is disclosed. The railway train control system includes a human-machine interface having a first display and a second, display. The first display provides a train control interface that enables a first operator, such as an engineer, to control one or more functions of the train. The second display is a multipurpose display that can switch between a standard mode and an application mode. The second display displays a read-only display of the train control interface in the standard mode and displays applications to enable a second operator, such as a conductor, to complete various tasks in the application mode.

Abstract: The present invention relates to a high-speed controlling device, suitable for displacing a switching element between two positions with very short switching times. Said device comprises two switchable electromagnets, between which an armature, with a driven coupling to the switching element, is arranged. According to the invention, said armature contacts the first electromagnet in the first position of the switching element and contacts the other electromagnet in the second position of the switching element. In order to obtain particularly short switching times for the switching element, the armature can be firmly secured to a shaft, which is rotatably mounted about its longitudinal axis and to which said switching element is also fixed in an axially offset manner in relation to the armature.
