Techniques for filtration systems are disclosed. In an example, a filtration system interrogates, via a radio-frequency identification (RFID) access device, a RFID tag that is positioned on a filter module that is positioned in the filtration system. In response to interrogating the RFID tag, the filtration accesses, an operational parameter stored on the RFID tag and associated with the filter module. The filtration adjusts an operational setting of the filtration system based on the operational parameter. The filtration system operates the filtration system based on the adjusted operational setting.

A delineator system includes an anchor having an end portion and a post extending along a longitudinal direction and having an end portion overlapping with the end portion of the anchor. The overlapping end portions are coupled together with an engagement member. A protective collar is moveable relative to the post and the anchor along the longitudinal direction from a non-installed position to an installed position. The protective collar is disposed over and covers the overlapping end portions and the engagement member when in the installed position. Methods of manufacturing and installing a post, and other delineator systems and delineator posts are also provided.

A portable roadway warning device includes a core having a plurality of weights embedded in a polymeric material, wherein the weights have a greater density than the polymeric material, and a housing having opposite first and second side surfaces, a leading edge, a trailing edge, and an upper vehicle interface surface. The housing covers the core. The leading and trailing edges define a distance D therebetween, wherein each of the weights has a maximum lengthwise less than &#xbd; D. A first connector member extends outwardly from the first side surface, and a second connector member extends outwardly from the second side surface. An assembly of roadway warning devices, and methods of installing and manufacturing such devices, are also provided.

A self-righting post assembly includes an elastomeric hinge tube and an elastomeric inner member is disposed in the hinge tube. In one embodiment, an extension post is disposed over the hinge tube. A sign panel can be secured to the extension post. In one embodiment, the inner member is free of any engagement with the hinge tube. In one embodiment, the hinge tube is secured to a base, preferably with a vertically oriented fastener. A method of assembling the post assembly is also provided.
