A bollard system having a main post; a post collar; a base plate; and an energy-absorbing element. The base plate has an arcuate outer wall and inwardly projecting mounting fastener notches around the bottom of the base plate. The post, the post collar and the base plate are shaped such that when the post is loaded above the base plate, an obliquely, downwardly directed sliding movement of the post and post collar relative to the base plate is obtained and is damped by the energy-absorbing element.

A post sleeve includes a reinforced concrete body preformed around a liner that defines a cavity extending longitudinally within the body, sized to receive a post. Standoff ribs run lengthwise within the cavity and extend inward from inner walls of the cavity. A post in the cavity is supported laterally by the standoff ribs. Drain channels between the ribs permit water to flow past the post and exit the cavity via a lower aperture. A drain tube is coupled to the lower aperture, and extends downward where it is covered with gravel at the bottom of a post hole. Concrete is poured around the post sleeve in the hole. The cavity is adaptable to receive posts of varying sizes, and at various depths. A collar closes a space between the post and the top of the cavity, permitting air circulation within the cavity while shedding water and substantially preventing insects from entering the cavity.

A system and method for marking the locations of curbs, driveways, roads, and boundaries utilizes a plurality of elongated, flexible, resilient markers installed within the ground by a rigid, elongated tubular member having a diameter greater than the diameter of the markers to be installed. The tubular member has a closed capped top and an open bottom. A given location marker is positioned perpendicular to the ground, adjacent to the location of a curb or driveway. The open bottom end of the tubular member is then positioned over the top end of the location marker and the tubular member is slid down over the marker. The impact of the closed top of the tubular member on the top end of the location marker drives the marker into the ground.

A foldable outdoor panel assembly is provided including an outdoor panel and a rotating mount assembly for maintaining the outdoor panel in a desired first orientation. The rotating mount assembly includes a first mount assembly connected to the panel and including a first mount, a first magnet having a first polarity and a second magnet having a second polarity. The rotating mount assembly further includes a second mount assembly having a second mount ratably connected to the first mount and including a third magnet having the first polarity. The second mount is connected to a post or other structure attached to the ground. The position of the first magnet adjacent to the third magnet maintains the panel in the first orientation or in an un-deflected condition while the position of the second magnet adjacent to the third magnet biases the panel from a second orientation or deflected condition back to the first orientation or un-deflected condition.

A self-rightening post system is configured to secure a post in a casing in a desired or vertical orientation and to self-righten the post upon the removal of a deflecting force, such as from a car or lawnmower. A self-rightening post system utilizes a plurality of adjustable retainer assemblies that are configured between the post and the inside surface of the casing to produce a self-rightening force upon deflection of the post. The plurality of adjustable retainer assemblies may be configured around the post and/or on opposing sides of the post to ensure that the post will self-righten regardless of the direction of a deflecting force. The casing may be a tube and the self-rightening post system may allow the post to rotate within the casing thereby allowing a user to change a desired rotational orientation.

An apparatus includes a post having a first end and a second end, the post having a flange disposed at the first end, at least one anchor assembly, and a base assembly including an opening for receiving the first end of the post, and an anchoring region including at least one aperture for receiving the at least one anchor assembly, the base assembly having a shape that is bisectable by a line segment into a first region and a second region. The opening has a first centroid disposed in the first region and the anchoring region has a second centroid disposed in the second region.

Systems and methods for deploying emergency roadside signaling devices are disclosed. In one aspect, a control system for an object placing device of an autonomous vehicle includes a processor, and a computer-readable memory in communication with the processor and having stored thereon computer-executable instructions to cause the processor to: receive a signal comprising instructions to activate the object placing device; and provide instructions to the object placing device to place a plurality of signaling devices in accordance with predetermined criteria.
