Abstract: A rack with a mounting bay to accommodate servers, wherein 1) the mounting bay defines two opposing internal areas disposed parallel to an insertion direction of the servers and divided into a multiplicity of slots, 2) one or more data lines for data connection of servers are configured in the rack, 3) the data lines include optical data lines, and 4) on at least one of the two internal areas of the mounting bay, an end section of a data line with a data interface is disposed on each slot such that a contactless optical data connection to a further data interface on a corresponding server is enabled.

Abstract: A flexible support includes a support member, two steel strips, and two fixing elements. The support member includes a plurality of support elements disposed together. The adjacent support elements are connected by a connection element to cascade the support elements. Two clamp structures are respectively extended from two sides of each support element. Two steel strips are respectively clamped by the clamp structures of the two sides of the support elements. Two steel strips have a spacing therebetween. Two fixing elements are respectively fixed to two terminals of the spacing. A bendable lamp device structure using the flexible support is also disclosed. The lamp cap is stably fastened to the flexible support. The user may bend the support to acquire light sources of differ angles with the lamp cap kept at the same level or direction.

Abstract: An electronic device (1), which can assume an operating state and at least one energy-saving state, with a power supply (7) that can be connected to a mains voltage, and an evaluation unit (4), which can control the electronic device (1) from the operating state into the energy-saving state and vice versa, wherein the evaluation unit (4) is connected to the power supply (7) in such a way that the power supply (7) can be turned off by the evaluation unit (4) for assuming the energy-saving state and can be turned on again for assuming the operating state, and the evaluation unit (4) can be supplied, at least in the turned-off state of the power supply (7), with energy from another electronic device, which is connected via a standard interface to the electronic device, and/or with energy from a capacitor and/or with energy from an accumulator and/or with energy from a solar cell.

Abstract: An electronic device includes an ion cooling system for cooling system components of the device. Through an arrangement, ionization of an air flow caused by the ion cooling can be determined and the electrostatic charge on the components that are located within the air flow can be measured.

Abstract: A device that can be used in an optical data network includes a receiver and a data port. The receiver receives data transmitted wirelessly by means of modulated light from a transmitter. During operation, the receiver is aligned to the transmitter as a function of a signal strength measured by the receiver. The data port can be connected to a computer system.

Abstract: The invention relates to printed circuit board test devices (1) comprising a support (4) receiving a circuit board (5) by said board's edges, said board being designed to be fitted as needed with electrical or electronic components (20), said devices further comprising at least one needle (15) which is connected to an electrical test device (17) and which shall electrically contact contact areas (21) on the board (5), the needle (15) being obliquely displaceable by a needle drive (13) in the needle direction, the needle drive being adjustable—by at least one holding-fixture drive (8)—in a adjustment plane (7) which is parallel to the circuit board (5), the drives (8, 13) being actuated by a needle control (10) to spatially position the needle tip (18) at a predetermined spatial coordinate, said devices (1) being characterized in that it includes a distance measuring device (25, 13?) designed to measure the distance between the adjustment plane (7) and the circuit board (5, 5?) at least at one site and to tran
