A floor protector for a security access system, comprising a rigid floor assembly having front and rear edges, the floor assembly comprising at least one floor plate and a base mounted underneath the floor plate, the base being at least partially spaced from the floor plate enabling cabling to pass between the two, and elastomeric entry and exit ramps supporting the front and rear edges of the floor assembly; wherein the base has protrusions at its front and rear edges which locate within respective grooves in respective elastomeric ramps, spaced a distance above the lower surface of the ramp, so as to support the base spaced above the whole or a major part of the floor that it overlies.

An electrical floor box assembly includes a box having a bottom wall, a plurality of side walls and a top portion having an opening at a top end thereof for providing access to the electrical box. An adapter has an open top end, an open bottom end and a passage extending between the top end and bottom end. The adapter has an outer dimension complementing a dimension of the opening in the electrical box and is received in the opening for movement between a retracted position and an extended position within the opening. The electrical box and adapter are configured for coupling and fixing the axial movement of the adapter with respect to the electrical box by rotation of the adapter to a locking position. In one embodiment, the electrical box and the adapter have interlocking teeth that mate with each other to prevent axial movement of the adapter. A locking member is provided to fix the position of the adapter relative to the electrical box to prevent rotation of the adapter.

According to an embodiment of the present invention, a power supply apparatus for detecting a gas leak is provided. The apparatus may include: a power supply pipe which is connected to a pump and has a power line passing therethrough, the power line supplying power from a power supply unit to a motor in the pump; a flexible joint pipe having one side connected to the power supply pipe and the other side connected to the power supply unit; a power inlet unit having one side facing the pump and the other side positioned on the power supply pipe so as to face the power supply unit to connect the power line, and preventing gas leak from one side to the other side in the pump; and a leak detection unit which fills the power supply pipe with an inert gas and detects a gas leak according to a change in pressure.

A floor panel constituting a floor surface in a room of a vehicle, an undercover arranged at a predetermined interval on a lower side in a vertical direction of the floor panel, a wire harness arranged with respect to the undercover and transporting electric power, and a connector attached to the wire harness and capable of electrical connection and disconnection, wherein a mounting structure of an electric wire includes a cover member arranged in a direction perpendicular to the undercover and provided so as to cover the connector, and the cover member is fastened so that an inside accommodating the connector is in a liquid-tight state with respect to the undercover.

A system for transmitting electrical energy from an energy source to a consumer, e.g., for contactlessly transmitting energy to a mobile consumer, includes a first line conductor and a second line conductor. Each line conductor has, in a respective axial direction, an at least approximately rectangular cross-section, the long sides of which are longer than the broad sides. The axial directions of the line conductors extend at a right angle with respect to a vertical direction. The first and second line conductors intersect in an intersection region in which a holding device is arranged, and are arranged outside the holding device such that the long sides of the line conductor cross-sections are parallel to the vertical direction. The first and second line conductors are arranged in a central region of the holding device such that the long sides of the line conductor cross-sections are oriented at a right angle with respect to the vertical direction.
