An element-shielding device includes a first rod including a first stake configured for insertion into the ground; a second rod including a second stake configured for insertion into the ground at a distance from the first stake; and a barrier material disposed between the first rod and the second rod. The barrier material is extendable and retractable between the first rod and the second rod. An element-shielding system includes a plurality of element-shielding devices.

A mailbox protection device is provided. The device may include an angular deflection surface. The angular deflection surface may include a first planar deflection panel and a second planar deflection panel contiguous along a linear vertex. The linear vertex may be directed toward, for example, oncoming traffic to deflect impacting snow away from a mailbox. The impacting snow may come from passing snowplows, for instance. The device may also include a receiving channel. The receiving channel can be defined in the linear vertex extending through the device from an opening at a top end of the linear vertex to an opening at a bottom end of the linear vertex. The receiving channel may receivably cooperate with a known fence post to anchor the device in the ground.

The invention concerns a visual screening system wherein the visual screening system is fabricated as a mobile barrier device made of textile material.

A portable free-standing traffic incident screening assembly of flexible fabric (tarp, screen, etc.) stretched between at least two stanchions, each stanchion having at least three adjustable legs, flexible telescoping vertical extension portions, and removable ballast. The portable screens defend incident sites by establishing privacy, reduce the probability of secondary accidents due to an unprotected scene, and provide a secure environment for incident investigators.

An avalanche triggering apparatus having a tower, a detonation chamber, and gas supply lines that are configured to deliver fuel gas and oxidizer to the detonation chamber. The flow is gas is controlled remotely, and a spark plug is configured to ignite gases within the detonation chamber based on the flow of fuel gas through a flow switch that acts as a sensor. The detonation chamber has a closed, rounded top and an open bottom end that is configured to face a snow surface. The detonation chamber is connected to the tower via mounting brackets and two pairs of isolator springs. Each isolator spring is comprised of a helical cable isolator that is inserted through a plurality of holes in two aluminum members in a helical configuration. The tower is comprised of at least two sections that are secured together via flanges.
