摘要： A current sensor (100) integrated into a printed circuit board (PCB) (102) for sensing a current flow (104) through a first conductive path (106). The current sensor (100) comprises a first conductive winding (110) forming an open shape (112) in a plane of the PCB (102), wherein the open shape (112) has a first end (114a) and a second end (114b) and delimits a sensitive region (116) in a plane of the PCB (102) for sensing the current flow (104) through the first conductive path (106) arranged within the sensitive region (116). The first conductive winding (110) is formed of a conductor having a plurality of turns extending across a thickness (d) of the PCB (102) and the first conductive winding (110) is spaced from an obstacle (108) in the PCB (102) by at least an insulation distance (118) from the first end (114a) to the obstacle (108).

摘要： A sealing system can be mounted between a body of a vehicle and a box fastened to the body. The body and the box include a first opening and a second opening, respectively, opposite each other. The sealing system surrounds the passage and includes a bellows having a first end in contact with the body so as to surround the first opening, and a second end in contact with the box so as to surround the second opening. The sealing system comprises a compression spring. Each end of the spring acts on one of the two ends of the bellows so that the spring moves the two ends of the bellows away from each other.

摘要： A bogie for a railway vehicle includes a frame, which has a first side beam and a second side beam extending along a longitudinal axis of the bogie and spaced apart from each other. A secondary suspension system is located on the frame and includes a first suspension assembly, which includes a first air spring and a first auxiliary spring positioned at the first side beam. The first air spring is positioned below and is arranged to be pressurized for supporting the body of the railway vehicle above the frame. The first auxiliary spring is fixed to an upper side of the first side beam underneath and spaced apart from the first air spring. The first suspension assembly further includes a first force-transmission mechanism configured to transmit forces exerted by the body on the first air spring to the frame via the first auxiliary spring.

摘要： A multimodal terrestrial transport network (1) includes first and second networks (L1, L5), each of which is equipped with an operating system (SE1, SE2). The module (63) according to the invention is associated with an interchange station (H3) where the first and second networks are interconnected. It includes: an interface (83) for communicating with the operating systems of the first and second networks; means (84) for providing an overview of the traffic in a monitoring area (DS3) covering part of the first and second networks in order to update the overview data based on traffic data provided by the operating systems, and an engine (87) for executing operating rules based on the overview data and suited to generate instructions suited to modify the traffic within a control area (DC3).

摘要： A pulse width modulation system including a plurality of module building blocks. A master control board includes a master board timer to generate a clock signal having a master timer rate. Each of slave control boards includes a slave board timer and is configured to determine a fictive master board timer based upon timer information received from the master control board via a communication bus, and further to synchronize the timer rate of the slave board timer to the master timer rate. The timer information includes timer offset information defining a time offset between the master board timer and the slave board timer The slave control board applies the time offset in control of pulse width modulated phase outputs such that the position of a slave pulse width modulated phase output signal is controlled in relation to the fictive master board timer.
