Abstract: A portable liquid vaporizer (1) comprises a reservoir (10) for holding a liquid to be vaporized; a heater (12) for vaporizing the liquid; a mouthpiece (3) for withdrawing the vapor; and an air path (30) extending through the vaporizer (1), comprising a heating section (31) and a cooling section (32), wherein the heating section (31) extends along the heater (12) and the cooling section (32) extends directly downstream from the heater (12) to the mouthpiece (3).

Abstract: A portable loose-leaf material vaporizer 1 comprises a heating chamber 20 for housing loose leaf material and vaporizing one or more active agents from the loose-leaf material, a mouthpiece 3 for withdrawal of the one or more active agents vaporized from the loose-leaf material, and a processing unit. The processing unit is configured to control temperature of the heating chamber 20 and to estimate a dosage of the one or more active agents withdrawn from the vaporizer 1 based on a mathematical model. The mathematical model relates vapor generating time and loose-leaf material properties, and optionally temperature of the heating chamber 20, to the dosage of the one or more active agents withdrawn or to be withdrawn from the vaporizer 1.

Abstract: A configurable pickup bed utility management system features a segmented panel assembly pivotally mounted to a pickup bed. The panel assembly features a first panel, a second panel pivotally located on the first panel, a third panel pivotally located on the second panel, and a fourth panel pivotally located on the third panel. A plurality of curved linear extrusions with ridges are located on the panels. The panel assembly can be fully extended over the pickup bed forming a bed cover structure, fully extended posterior to the pickup bed forming a work surface structure, fully extended posterior to the pickup bed forming a ramp structure, partially extended posterior to the pickup bed forming a sun shade structure, folded into the pickup bed forming a lockable toolbox, or folded into the pickup bed forming a bed extender.
