Abstract: One embodiment is directed to a tray for use in a subrack of a rack, the tray comprising a printed circuit board configured so that a plurality of connections can be made at a plurality of positions on the printed circuit board. Each of the plurality of connections involves at least one connector having an RFID tag associated therewith. The tray further comprises a plurality of RFID antennas integrated into the printed circuit board, each the RFID antennas associated with a respective one of the positions. The printed circuit board is configured to localize a field emitted from each RFID antenna so that only the RFID tag associated with that RFID antenna is energized and read.

Abstract: A transparent electric conductor includes titanium oxide doped with aluminum and at least one other dopant: either in the form Ti1-a-bAlaXbOy, where X is a dopant or a mixture of dopants selected from the group consisting of Nb, Ta, W, Mo, V, Cr, Fe, Zr, Co, Sn, Mn, Er, Ni, Cu, Zn and Sc, a is in the range 0.01 to 0.50, and b is in the range 0.01 to 0.15; or in the form Ti1-aAlaFcOy-c, where a is in the range 0.01 to 0.50, and c is in the range 0.01 to 0.10. With the above composition, the electrical conductivity and the light transmittance are suitable for use of the transparent electric conductor in various applications, in particular as a transparent electrode of an electronic device.

Abstract: One embodiment is directed to a subrack comprising a backplate and at least one tray configured so that a plurality of connections can be made at a plurality of positions on the tray. Each of the plurality of connections involves at least one connector having information stored in a device associated therewith that can be read. The backplate and the tray are configured so that the tray can be selectively attached and removed from the backplate. The backplate and the tray are configured so that the devices associated with the connectors involved in making the connections can be read via the tray. The devices associated with the connections can be implemented, for example, using RFID tags or connection point identifier (CPID) storage devices (such as EEPROMs).

Abstract: The present invention relates to a lighting control system, comprising a control unit comprising a memory in which control programs are recorded. The control programs are capable of controlling the optical transmission through an active window pane with electro-controllable optical transmission properties and are capable of controlling an electro-controllable lighting device. The system furthermore comprises a coloration sensor for measuring a value representative of a coloration of the light. The control programs are capable of controlling the lighting generated by the lighting device as a function of the value supplied by the coloration sensor.

Abstract: The present invention relates to a system for controlling the optical transmission of a plurality of windows Vk with electro-controllable optical transmission properties, comprising at least one spatial brightness sensor for supplying at least one value representative of brightness respectively for different spatial areas forming subsets Xi of a set X and thus supplying a mapping L of a brightness in which the subsets Li of L are associated with the sets Xi, and a control unit comprising a memory in which programs are stored which are capable of controlling the optical transmission of each of said windows.

Abstract: A surface treating appliance includes a plurality of frusto-conical cyclones arranged in parallel. Each cyclone has a relatively wide, rigid frusto-conical portion and a relatively narrow, flexible frusto-conical portion connected to the relatively wide portion. The relatively wide portion includes at least one dirty air inlet, and the relatively narrow portion includes a dirt outlet. The relatively narrow portion vibrates during use of the appliance is dislodged dirt from the inner surface of the relatively narrow portion, the dislodged dirt being expelled from the dirt outlet.

Abstract: The invention concerns a LED lighting body (1) comprising an inner tubular structure (2) made of a heat conducting and electrically insulating material, LEDs (6) associated with a first end (3) of the inner tubular structure (2), an electronic control circuit (8) of the LEDs (6) housed in the inner tubular structure (2), a base (9) associated with a second end (4) of the inner tubular structure (2) on the side opposite the first end (3) and electrically connected to the control circuit (8) and a sleeve (11) arranged externally and coaxial with the inner tubular structure (2), which defines at the level of the first end (3) of the inner structure (2) an annular housing (12) which accommodates a lower portion (131) of a bulb (13) covering the LEDs (6).
