A combination traffic barrier and roadway repair system for use on a traffic way, such as a roadway, runway, taxiway or the like, includes an elongated base and an elongated rectangular slab. The base configured to support the rectangular slab in a vertical orientation when used as a barrier. The rectangular slab being detachable from said base and configured to be placed flush with a traffic way surface, thereby forming a portion of the traffic way.

A barrier includes recycled rubber portions molded around a core infrastructure. The core infrastructure may itself include recycled rubber in a containment body. The containment body may include baled recycled or other waste material. The barriers may be stacked or connected to form a barrier structure useful in environmental control and other applications. The method for making the barriers includes molding rubber portions and a binder around a core infrastructure.

Disclosed are a virtual barrier gate system (10) and a virtual barrier gate control method. The system comprises a control apparatus (100) and a holographic projection apparatus (200) connected to the control apparatus (100), wherein the control apparatus (100) is configured to generate a first control signal on the basis of a starting signal and send the first control signal to the holographic projection apparatus (200); and the holographic projection apparatus (200) is configured to project, according to the first control signal, a three-dimensional holographic image with a specified shape to a preset position to serve as a virtual barrier gate. By using air holographic projection technology, a physical barrier gate is virtualized into an air holographic projection image, thereby improving the safety of the barrier gate and reducing labor costs.

The portable privacy screen includes one or more barrier sections, a plurality of guylines, and a plurality of stakes. The portable privacy screen may be a visual barrier that may be adapted to be erected at an accident scene to provide privacy for an accident victim. An individual barrier section selected from the one or more barrier sections may be collapsed for storage within an emergency vehicle when not in use. The individual barrier section may be secured in place by a plurality of aprons located at the bottom of the individual barrier section, by the plurality of guylines, by the plurality of stakes, or by any combination thereof. The one or more barrier sections may be coupled end-to-end to lengthen the visual barrier.

A handrail for a railroad vehicle is disposed in a cabin of a vehicle body of the railroad vehicle. The handrail includes a handrail body whose inside serves as a filling space and a filler having fluidity and filling the filling space. The handrail body includes an opening to be used in supplying the filler to the filling space and a plug that opens and closes the opening.
