Abstract: An apparatus (1) comprising hardware equipment (3) having hardware components (10) enclosed by a chassis (2) having a front side (2A) and a rear side (2B), and auxiliary equipment (5) movable within the chassis (2) along at least one transportation rail (7) with a non-linear trajectory extending in horizontal plane between a first position at the front side (2A) of the chassis (2) and a second position behind the hardware equipment (3) at the rear side (2B) of the chassis (2), wherein a part of the hardware components (10) is at least temporarily removable from the chassis (2) or movable within the chassis (2) to provide space (11) for moving the auxiliary equipment (5) within the chassis (2) along the at least one transportation rail (7) between the first and second position.

Abstract: An optical detection device and method for detecting temperature changes and/or wavelength changes of an optical probe signal includes transmitting an optical probe signal having a predetermined wavelength to an optical input port of an optical waveguide; detecting first and second optical detection signal at first and second optical output ports via first and second opto-electrical converters which create corresponding first and second electrical signals; measuring values of the first and second electrical signal and determining an absolute temperature or a temperature change of the optical waveguide and/or an absolute wavelength value or a wavelength change of the optical probe signal via values measured of the first and second electrical signals and first and second previously determined wavelengths and temperature dependencies of both first and second power transfer functions.

Abstract: An outdoor device of a timing system includes a receiver for receiving clock information from a satellite system, a processing system for running master functionality of a clock synchronization protocol to transfer the clock information to an indoor device of the timing system, and a transceiver for transferring data between the outdoor device and the indoor device. A memory device stores a fixed delay value estimating a time delay from a reception moment of a request message related to the clock synchronization protocol to a transmission moment of a reply message. There is no need to compute a difference between clock times corresponding to the reception moment and the transmission moment because the fixed delay value is used in lieu of the difference in the clock synchronization protocol. Thus, quality requirements related to an oscillator of the outdoor device can be mitigated.
