Abstract: Devices and methods for vaporizing active ingredients of a selected substance for inhalation using a portable vaporization device are provided herein. In certain aspects, the device includes a portable power source, a heating portion, an inhalation sensor, a temperature sensor, a distal light source, and a grinding portion. In response to an inhalation by a user, the power source energizes a heating element of the heating portion so as to heat air flow to a desired vaporization temperature within a few seconds of detecting inhalation, using convection and radiative heating. The device may include a receptacle for receiving a cartridge containing a pre-prepared substance, such as a liquid, gel, powder, or solid brick, and a grinding portion to allow a user to grind intact portions of cellulose-based material into smaller pieces to facilitate vaporization by manually rotating portions of the device relative to each other.

Abstract: A selectively removable and foldable hot tub seat system that is movable to provide additional free area with the hot tub such as when aquatic exercise is desired in the hot tub, and yet can be readily returned into position for seating when a more relaxing use of the hot tub is desired. The foldable hot tub seat system also includes a seat that has an adjustable height, allowing for use by users of differing heights and/or seat height preferences. The hot tub seat system does not require any mounting hardware and may be installed, removed, and adjusted without requiring any tools.
