A mounting post of variable length that may be attached between a local floor and ceiling. The mounting post may include a cable access hole near respective upper and lower extremities of the mounting post.

A safety barrier assembly for a parking garage is positioned in proximity to an opening in a floor of the parking garage that accommodates vertical movement of a VRC between floors of the parking garage. The safety barrier assembly has left and right vertical guide columns. A handrail and a knee rail have opposite ends guided for vertical movement in the columns. A bottom rail is connected pivotally to the knee rail and hangs to a position below the knee rail when the knee rail is in the lower position. An actuator causes the bottom rail to pivot up as the knee rail is elevated.

Systems and related methods related to structures with large-scale rotatable elements. Some of the present systems comprise: a tower defining a plurality of human-habitable spaces; a tower hub coupled to the tower and having a transverse dimension of at least 50 feet; an observation wheel rotatably coupled to the tower and having a central wheel hub; and one or more bearings disposed between the tower hub and the wheel hub to rotatably support the observation wheel relative to the tower.

An underground-structure construction method of arranging an underground structure by causing drilling apparatuses engaged with a concrete-made closed-shaped bottom frame to travel in a reciprocating manner to drill a just-underground of a bottom part of the underground structure, discharging to an earth surface excavated earth and sand of an internal ground, and extending a building frame of an upper part of the underground structure includes: open-cutting a ground to form a larger-sized mortar-shaped working hole; forming a closed-shaped horizontal reference area in an edge ground; arranging a bottom frame on the horizontal reference area; building a first stage building frame on the bottom frame; and backfilling, with backfill soil, an annular-shaped outer space of inner and outer spaces as a result of dividing the working hole, the drilling apparatuses being caused to uniformly drill, from the horizontal reference area as a drilling initiation plane, the just-underground of the bottom part.

Parking detection sensor (100) has a Doppler sensor (110), a magnetic sensor (120) that detects magnetism on XYZ axes, a change point detection unit (130) that detects a change point in the output of the Doppler sensor (110) and the magnetic sensor (120), a level difference detection unit (140) that detects the magnetic level difference over time in the output of the Doppler sensor (110) and the magnetic sensor (120), and a state assessment unit (150) that assesses the parking state of a vehicle on the basis of the detection results of the change point detection unit (130) and the detection results of the level difference detection unit (140).
