Abstract: A filter element, in particular an air filter element, has a filter media body surrounding a hollow interior and has a first end and an opposite second end. A first end cap is positioned on the first end of the filter media body, and a second end cap is positioned on the second end of the filter media body. The second end cap is a closed end cap. The second end cap has a plurality of spaced-apart inner adapter projections arranged thereon and projecting in direction of a central axis away from the first end cap. At least some of the inner adapter projections are positioned in a circular arrangement so as to surround a center of the second end cap. Such a filter element is arranged in a housing of a filter system provided with a receiver arrangement for the filter element.

Abstract: This disclosure includes methods for testing hydraulically-actuated devices and related systems. Some hydraulically-actuated devices have a housing defining an interior volume and a piston disposed within the interior volume and dividing the interior volume into a first chamber and a second chamber, where the piston is movable relative to the housing between a maximum first position and a maximum second position in response to pressure differentials between the first and second chambers. Some methods include: (1) moving the piston to the first position by varying pressure within at least one of the first and second chambers such that pressure within the second chamber is higher than pressure within the first chamber; and (2) while the piston remains in the first position: (a) reducing pressure within the second chamber and/or increasing pressure within the first chamber; and (b) increasing pressure within the second chamber and/or decreasing pressure within the first chamber.

Abstract: A disturbance, for example, a frequency variation, is generated in at least a portion of the power distribution network. The disturbance may be generated, for example, by an uninterruptible power supply (UPS) or some other component of the power distribution network, such as a switch. At least one node of the network experiencing the disturbance is identified and a topology of the power distribution network is determined responsive to identifying the at least one node. The at least one node may be identified by detecting a voltage-related artifact corresponding to the disturbance. A phase-locked loop (PLL)—based circuit may be used for fast artifact detection. Groups of devices in the network may be identified from the artifacts, and combinatorial optimization techniques may be used to determine connectivity within such groups.
