Abstract: Bed heating systems that include a DC-heated bedding assembly and/or a DC-powered control system. The DC-heated bedding assembly includes a substrate, which supports a heating element configured to receive electrical power from a DC power supply and to generate a heat output to heat the substrate. The heating element may extend sinusoidally along the substrate. The heating element may be configured to generate different heat outputs in two or more zones of the substrate. The DC-powered control systems are configured to selectively regulate electrical power that is supplied to the heating element of the DC-heated bedding assembly. The DC-powered control systems are configured to monitor detected voltage(s) at one or more voltage taps positioned along the length of the heating element. Responsive to detecting a deviation between the detected voltage and an expected voltage, the DC-powered control systems may reduce and/or cease the supply of power to the heating element.

Abstract: An article of collapsible luggage includes a front surface, a plurality of front perimeter walls forming a closed perimeter around the front surface, and a split wing assembly having a left wing and a right wing. Both wings are pivotally attached the front perimeter walls and configured to rotate between a reinforcing position and a collapsing position. In the reinforcing position, the wings reinforce corners of the collapsible luggage and maintain the plurality of front perimeter walls substantially perpendicular to the front surface. In the collapsing position, the wings do not reinforce the corners of the collapsible luggage, thereby allowing the plurality of front perimeter walls to collapse into a substantially coplanar arrangement with the front surface.
