Abstract: A lightweight heat reflective shield useful for hikers and campers to reflect heat from a campfire back toward themselves. The heat reflective shield includes a base panel and a concave body portion attached to and extending upward from the base panel and supported by at least two inflatable ribs. The concave body portion includes an open front face along a front edge of the base panel, an inner side, and an outer side, wherein at least a portion of the inner side includes a heat reflective material. When the inflatable ribs are filled with air, the heat reflective shield may accommodate a standing or seated person, and when positioned adjacent a heat source, the heat reflective material of the inner side reflects heat from the heat source back toward the heat source.

Abstract: In some examples, an apparatus can include a syringe body including an electrical interface at a side surface of the syringe body, an interface at an end of the syringe body including an output at a distal surface of the syringe body, a print material particles reservoir located in the syringe body, and a structure to adapt a volume of the print material particles reservoir to move print material particles out of the print material particles reservoir through the output, where in response to the volume adapting structure moving from a first position to a second position, a signal is transmitted by the electrical interface.
