    摘要: A method of determining a gauge and a tilt of a rail track at a location includes providing a rail trolley including a processor, a memory coupled to the processor, an RFID reader, a gauge sensor, and a tilt sensor and positioning the rail trolley on the rail track at the location. The method also includes interrogating one or more RFID tags positioned along the rail track and determining, using the processor, a fixed location associated with each of the one or more RFID tags. The method further includes determining, using the processor, the location of the rail trolley in relation to the fixed locations associated with each of the one or more RFID tags and determining the gauge and tilt of the rail track at the location of the rail trolley.

    摘要: A Q-switched laser, which is pumped by at least one pump source (8), providing pulses. The laser comprises two mirrors (3,5) providing a laser cavity, in which a gain medium (2), a saturable absorber (4) and a controllable active modulator (6) is situated. Loss can be introduced in the modulator (6) by a control device (10). In a first phase, said control device (10) introduces loss in the active modulator, setting a threshold inversion density band to a level (B) high enough to be above the actual inversion density in the gain medium means. In a second phase, the control device lowers said loss instantly, which will lower the threshold inversion density band to a level (A) lower than the actual inversion density in order to activate emission of said Q-switched pulse.
