Abstract: An aquarium includes a first chamber arranged to contain a first volume of liquid, a dry chamber that is adjacent the first chamber and defines a second volume, and a removable element at least partially disposed within the dry chamber. The removable element is selectively removable from the dry chamber. The aquarium also includes a filter at least partially disposed within the removable element, and a pump including an intake and an outlet. The intake is arranged to draw a flow of liquid from the first volume of liquid during pump operation. The aquarium also includes a tube having a first end connected to the outlet and a second end movable between a first position in which the flow of liquid passes through the filter and is then discharged into the first volume and a second position in which the flow of liquid flows directly into the first volume.

Abstract: A light member includes a housing having a top side and a bottom side. The top side faces away from a space to be lit, and the bottom side faces the space to be lit. A lighting control region is disposed on the bottom side of the housing that illuminates the space and has a first control channel, a second control channel, and a neutral channel. A first light-emitting module is electrically connected to the first control channel and the neutral channel and a second light-emitting module is electrically connected to the second control channel and the neutral channel. A switch assembly is coupled to the housing and is operable to selectively deliver power to the first control channel and the second control channel.

Abstract: An aquarium includes an outer housing including a bottom wall and a side wall extending from the bottom wall, the outer housing defining a first interior tank volume to house water. The aquarium also includes a base disposed inside the first interior volume and coupled to the bottom wall, the base including an aperture. The aquarium also includes an inner housing coupled to the base, the inner housing defining a second interior tank volume to house water, wherein the aperture provides fluid communication between the first and second interior tank volumes.

Abstract: The invention is related to a smart testing apparatus and preferably a method for testing at least a first DUT and a second DUT using a mobile communications testing device. The method comprises the steps of determining, whether a first RF test signal from/to the first DUT interferes with a second RF test signal from/to the second DUT. It determines, whether the second RF test signal from/to second DUT interferes with the first RF test signal from/to the first DUT. It predetermines, whether at least measuring the first measuring result obtained by applying the first RF test signal is disturbed above a first disturbance threshold value. It predetermines, whether at least a second measuring result obtained by applying the second RF test signal is disturbed above a second disturbance threshold value.

Abstract: A test system for testing a plurality of devices under test (DUTs) is provided. The test system comprises a test signal generator configured to generate test signals to be transmitted to the DUTs, wherein the test signals comprise at least one synchronization signal. The test signal generator is configured to broadcast the at least one synchronization signal to the DUTs. It is thereby possible to simultaneously test more than one DUT.

Abstract: A testing method for testing a plurality of devices under test (DUT) includes transmitting first testing routine signals from a first backend controller to a testing front end module via a wired data connection between the first backend controller and a first testing signal interface of the testing front end module, transmitting second testing routine signals from a second backend controller to the testing front end module via a wired data connection between the second backend controller and a second testing signal interface of the testing front end module, prioritizing one of the first and second testing routine signals according to predefined priority criteria in the testing front end module, and generating testing signals in the testing front end module on the basis of the prioritized testing routine signals.

Abstract: The present invention relates to a calibration method and a calibration arrangement for a RF test apparatus for testing a RF device under test. Instead, a calibration board is provided and connected to each of the cables of the RF test apparatus. A calibration board is configured to provide a plurality of connection loops by connecting the input/output channel terminals of the test apparatus one after the other with each other. This results to a bunch of different connection loops. Then a physical parameter, such as the attenuation over frequency, is measured for each of these connection loops. Since each physical parameter can be described by a single equation, this results to an amount of different equations which form an equation system. The idea underlying the present invention is that the amount of equations of this equation system, which amount corresponds to the different connection loops, is at least equal or higher than the amount of unknown parameters of the equation system.

Abstract: A switch-extender is connected to a measurement system and to several DUTs. It splits a signal from the measurement system into several signals so that the several DUTs receive the same signal and can therefore be tested in parallel. The switch-extender further includes at least one amplifier and/or at least one attenuator for every output port so that every signal has the same signal level no matter what the individual attenuation factor of the signal connectors or of the internal printed circuit board is. Furthermore a method for calibrating the measurement system as well as for the switch-extender and the signal connectors describes how to obtain the needed calibration values both for the downlink path and for the uplink path without changing the signal connector.
