A three-dimensional billboard display system features a flexible sheet of banner material having displayed content on a display side thereof, and a two-dimensional footprint area on the display side that is discretely identifiable from the displayed content. A flexible cover fastened to the flexible sheet in a position overlying the two-dimensional footprint area on the display side and enclosing a three-dimensional space between said cover and said flexible sheet. One or more inserts form a three-dimensional body of predetermined shape inside the three-dimensional space, the flexible cover spanning in taut condition over the three-dimensional body, thereby imparting the predetermined shape to the three-dimensional space and imparting the flexible cover with a three-dimensional form bulging outwardly from the display side of the flexible sheet. A reinforcement layer features a mesh or netting of criss-crossing webbing straps on a backside of the flexible sheet to carry the weight of the 3D embellishment.

An insulated heating-unit cover having an opening to permit air to circulate around the heating-source when a vent disposed at the top of the cover is opened, allowing heat into a space. The cover can include a heating-unit temperature sensor disposed within a space covered by the cover and a controller in wireless communication with a space temperature sensor located at a distance away from the heating-unit. The controller can be configured to operate an actuator such that the vent is open when the space temperature sensor indicates that the ambient temperature is below a set point temperature and such that the vent is closed when the ambient temperature is greater than the set point temperature. The controller can communicate with a plurality of other similar controllers and a central server to effect changes in the output of a central heating source coupled to a plurality of individual heating-units.

A backing plate for a hazardous material placard. The hazardous material placard comprises a hazardous material indicator that is a sequence of N characters indicating a type or limited class of hazardous material, N being a natural number. The backing plate is a metal plate having a size and shape approximately the same as the placard, and having N cutout portions that have been cut out from the backing plate corresponding to the sequence of N characters on the placard. The N cutout portions are positioned and sized so that the backing plate is positionable behind the placard so that the N cutout portions align with the N characters on the placard.
