Pivoting safety barrier for wheelchair lift

A safety barrier for wheelchair lifts is disclosed, and more particularly a safety barrier assembly which can be used singly or in opposed pairs to open automatically and mechanically in cafe-style, rotating 90 DEG from a first closed or barrier position to a second, open, pass-through position. More particularly, these barriers may be used as barriers on wheelchair lift platforms or at the door opening of a van or transit vehicles on which a wheelchair lift is mounted. The barriers typically are shaped like the letter P with the lower most barrier member being spaced from twelve inches to two feet above the floor, and which are designed to prevent wheelchairs from rolling out of the van when the platform has left the transfer level (vehicle floor), and as a safety barrier in the case of runaway wheelchair events. The preferred embodiment of the gate is mounted to a pivotal cam slot / bias spring assembly which provides for stable open and shut positions with spring / gravity assisted closure. The preferred embodiment also includes a safety interlock switch circuit which prevents lift platform motion when the gate barrier is open.

Safety barrier with illuminating components

A safety net that includes at least one illuminating element. The safety net is intended to be stored in a rolled-up fashion (similar to a roll-up window shade) in the trunk of a vehicle. When illuminated, the safety net provides a completely new and unique means of alerting oncoming traffic to a road hazard or other situation requiring traffic control. The safety net provides a warning means that will not be knocked over by the wind, as wind blows freely through the voids of the net. In addition, the safety net screens the scene from the view of those in oncoming traffic. The device may include a solid state controller that provides a variety of patterns or symbols to further enhance the visual safety features of the device. This can be accomplished by placing fiber optic strands in the net voids, or within the side illuminating fiber optic conduit itself. The device may also include metal cables to form a physical barrier.

Retractable safety barrier

A retractable barrier includes a rollup or otherwise retractable panel that can extend between two spaced apart support members. When not in use, the panel can retract onto one of the support members to permit passage. The barrier provides substantial impact resistance by having the reactive force of the impact transfer directly between the barrier's retractable panel and its support members without having to rely on the strength of the panel's take-up roller or the strength of the roller's anti-rotation mechanism. This can be accomplished by having a slot-engaging stop member mounted directly to the panel itself. The stop member is preferably a pipe, rod, bar or some other vertically elongate member that can broadly distribute an impact reactive force over the height of the panel. In some embodiments, the barrier can be set for various doorway widths by simply repositioning the stop member's location on the retractable panel.

Catheter insertion device with automatic safety barrier

A catheter insertion device with an automatic safety barrier includes a housing, a barrier member, and a biasing element. The housing includes a central bore configured to receive a needle therethrough, and further includes a channel extending through the housing and intersecting the central bore. The barrier member is hingedly coupled to the housing, and includes a leg to extend through the channel. An opening in the leg substantially aligns with the central bore to accommodate the needle therethrough. The biasing element biases the barrier member relative to the housing such that withdrawing the needle through the opening causes the biasing element to misalign the opening with the central bore, thereby occluding the central bore to shield an end of the needle.

Portable traffic safety barrier

The portable traffic safety barrier is formed of plastic or recycled rubber, and has a narrower upper portion and wider cap atop the upper portion to form a mushroom-shaped cross section. Elongate passages are formed through each barrier section, and a spring is installed in at least one passage to connect the barriers resiliently to one another end-to-end. Another passage contains a flexible coiled electrical cord to provide power for lighting the barrier, the lighting being installed atop the barrier sections. The springs and coiled cord allow connected barriers to separate in the event of impact, while still maintaining the integrity of the assembly and lighting. Wheels may be provided beneath the barrier sections to allow lateral repositioning. Two or more rows of barriers may be arranged laterally, and the resulting gap between barriers serves as a planter box or for the installation of signage.

Cabled massive security barrier

Masses of composite material are coupled together by means of one or more cables into a longitudinal barrier wall to provide security from terrorist threats by being able to withstand both vehicle collisions and explosive blasts. The one or more cables are routed through tunnels within the masses. The tunnels have tapered openings to protect cable from being sheared apart when adjacent masses slide relative to one-another. Some of the cable is anchored to some of the masses. Each mass that is located at an end of a barrier wall is used to support anchoring means to anchor some of the cable. Such barrier walls are supported by a surface such as a ground surface and can be dragged along such a surface since a ground anchoring means isn't required. Given sufficient cable, such a barrier wall can withstand great longitudinal tension, and can absorb and endure great amounts of mechanical and thermal energy.

Security barriers with automated reconnaissance

An intrusion delaying barrier includes primary and secondary physical structures and can be instrumented with multiple sensors incorporated into an electronic monitoring and alarm system. Such an instrumented intrusion delaying barrier may be used as a perimeter intrusion defense and assessment system (PIDAS). Problems with not providing effective delay to breaches by intentional intruders and / or terrorists who would otherwise evade detection are solved by attaching the secondary structures to the primary structure, and attaching at least some of the sensors to the secondary structures. By having multiple sensors of various types physically interconnected serves to enable sensors on different parts of the overall structure to respond to common disturbances and thereby provide effective corroboration that a disturbance is not merely a nuisance or false alarm. Use of a machine learning network such as a neural network exploits such corroboration.

Roadway barrier components formed using a system for recycling wet concrete and means for assembling multiple components into a continuous safety barrier wall

A wet concrete recycling system for mixing trucks returning to the cement plant throughout the workday. “Residual-collection” molds, kept on-hand at the plant, are filled with any excess wet concrete present in the returning trucks. The molds are configured to form finished components such as roadway barrier sections (i.e. jersey walls), and the like. The finished components are low in cost due to the use of recycled wet concrete, inexpensive reinforcing materials, and handles / assembly elements fabricated from other recycled materials. The finished components may be sold or leased to customers, thereby converting costs typically associated with traditional residual concrete disposal techniques into supplemental income streams. The finished components may be assembled into continuous roadway safety barrier walls. All structures assembled from two or more of the finished components are inexpensive due to the low cost of the individual components, easily constructed, and may be permanent or temporary in nature.
