The invention relates to adjusting at least one of installed building service sensors (10) of a building service system. A sensor coverage area of at least one sensor (10) is adjusted based on information on a position of the installed sensor (10) relative to at least one other sensor (10). For example, to determine the position of the sensor (10) relative to said at least one other sensor (10), each sensor (10) establishes a wireless communication between said sensor (10) and at least one other sensor (10) via a wireless communication means (34) of the sensor (10). For example, information on the positions of the installed sensors (10) is used to assign to each sensor (10) at least one of installed building service supply devices (12) of the system.

Masers and microwave amplifiers that can function in the continuous-wave mode at room temperature are provided. The maser system can include a diamond gain medium having nitrogen-vacancy centers, and a resonator can be disposed around the gain medium. The resonator can be disposed in a cavity box, and radiation (e.g., visible light) can be provided to the gain medium to cause emission of microwave radiation.

A method of providing a cooling apparatus for cooling a heat-dissipating component(s) of an electronics enclosure includes: providing a thermal conductor to couple to the heat-dissipating component(s), the thermal conductor including a first conductor portion coupled to the heat-dissipating component, and a second conductor portion to position along an air inlet side of the electronics enclosure, so that in operation, the first conductor portion transfers heat from the component(s) to the second conductor portion; coupling at least one air-cooled heat sink to the second conductor portion to facilitate transfer of heat to airflow ingressing into the enclosure; providing at least one thermoelectric device coupled to the first or second conductor portion to facilitate providing active auxiliary cooling to the thermal conductor; and providing a controller to control operation of the thermoelectric device(s) and to selectively switch operation of the cooling apparatus between active and passive cooling modes.

A plasmon-enhanced terahertz graphene-based photodetector exhibits an increased absorption efficiency attained by utilizing a tunable plasmonic resonance in sub-wavelengths graphene micro-ribbons formed on SiC substrate in contact with an array of bi-metallic electrode lines. The orientation of the graphene micro-ribbons is tailored with respect to the array of sub-wavelengths bi-metallic electrode lines. The graphene micro-ribbons extend at the angle of approximately 45 degrees with respect to the electrode lines in the bi-metal electrodes array. The plasmonic mode is efficiently excited by an incident wave polarized perpendicular to the electrode lines, and/or to the graphene micro-ribbons. The absorption of radiation by graphene is enhanced through tunable geometric parameters (such as, for example, the width of the graphene micro-ribbons) and control of a carrier density in graphene achieved through tuning the gate voltage applied to the photodetector.

A tool for assembly of an inner enclosure of a generator or a machine comprises a first part and a second part. The first part comprises a plate with one edge constructed to form a first half-ring. The second part comprises a second half-ring corresponding to the first half-ring of the first part. Upon assembly of the first part and the second part, the first half-ring and the second half-ring form a full-ring to encompass a shaft of the generator or the machine and to connect to an inner enclosure of the generator or the machine.

A laser module includes a laser source and an optical marshalling module. The laser source is configured to generate and output a plurality of laser beams. The plurality of laser beams have different wavelengths relative to each other. The different wavelengths are distinguishable to an optical data communication system.

A method and an apparatus for selectively cancelling the effect of the active center of a molecule are provided. The method comprises illuminating a target molecule with two synchronized ultrashort X-ray pulses using a laser, the two synchronized ultrashort X-ray pulses having different central photon energies the subtraction of which matches the photon energy of a peak of the core spectrum of the target molecule, such that a core state of an atom of the target molecule, and also of identical surrounding molecules, is selectively excited by the re-DFG effect as a result of the illumination. The method is implementable for simple or complex molecular systems and bulk materials.
