Abstract:

An elevator cab includes primary and auxiliary light sources. A light sensor responsive to light from the primary light source causes activation of the auxiliary light source when the primary light source fails.

Abstract:

An adjustable socket system includes a socket frame having a proximal area, a distal area opposite the proximal area, a first component arranged along a first side of the socket system, and a second component arranged along a second side of the socket system. The first component is connected to the second component. A tubular insert is arranged on an interior of at least the proximal area of the socket frame. The tubular insert forms an interior surface of the socket system. At least one tensioning element operatively connects the tubular insert to the first and/or second components. At least one tensioner is attached to the at least one tensioning element that selectively tensions the tensioning element to adjust a circumference of at least one area of the socket system.
