The apparatus further includes a storage compartment having an open cavity for receiving and holding an object and a third surface having a third contour that closely matches the first contour, the storage compartment supported by the base structure such that the first surface and the third surface are disposed immediately adjacent one another.

Abstract: A feeding tool for dispensing pet food out of a pet food container includes an adapter having a first aperture. The adapter is configured to be coupled to a container of pet food. The feeding tool also includes an actuator coupled to the adapter. The actuator is movable between a first position and a second position. The feeding tool also includes a control member coupled to the actuator. The control member includes a second aperture. The feeding tool also includes a cap coupled to the actuator. The cap includes a third aperture. The first and second apertures are aligned with one another in the first position to allow food to pass from the container into the actuator, and the second and third apertures are aligned with one another in the second position to allow food to pass from the actuator out of the cap.

Abstract: An aquarium includes a curved aquarium housing that supports water, the water including a water surface that separates water from air within the housing. The aquarium also includes a lighting system coupled to the aquarium housing, the lighting system including an arm and a light element disposed at an end of the arm and outside of the aquarium housing that directs light into the aquarium housing at an angle less than 90 degrees relative to the water surface.

Abstract: A system for displaying aquatic animals in a retail environment includes a base having a plurality of shelves, and a plurality of removable containment elements disposed on the shelves, each of the containment elements including a bottom, a top, and side walls extending between the top and the bottom to enclose a volume of water. At least one of the side walls defines a flat side viewing panel for viewing an aquatic animal inside of the containment element. Each of the containment elements is a rectangular-shaped that is sized to contain a salable number of aquatic animals.

Abstract: An aquarium includes a wall separating an internal environment within the enclosure from an external environment outside of the enclosure, and a power transmission system that transmits power wireless through the wall. The power transmission system includes a power source and an external inductor coupled to the power source, the external inductor coupled to the wall. The power transmission system also includes an internal inductor coupled to the wall and separated from the external inductor by the wall, and an internal element disposed within the enclosure, the internal element coupled to the internal conductor.

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: A containment vessel includes a tank having a front wall, a back walk two side wails, and a base. A top perimeter is defined by a top edge of the front wall, the back wall, and the two side watts and a bottom perimeter is defined by the intersection of each edge of a perimeter of the base and a bottom edge of each of the front wall, the back wall, and the two side walls. An over-frame is coupled to both the top perimeter and the bottom perimeter to at least partially visibly conceal the top perimeter and the bottom perimeter. The over-frame includes an over-frame top portion having a plurality of corner elements and side elements that are coupled together and an over-frame bottom portion having a plurality of corner elements and side elements that are coupled together.

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 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.

Abstract: The invention relates to a switching device for the alternate connection of at least one first test port or of a second test port to a measuring-device connection, where the measuring-device connection provides at least one test-signal input. The test-signal input is connected to a first signal path and to a second signal path, where the first signal path is connected alternately to the first or to the second test port, and the second signal path is connected at least to the respectively other test port.
