Abstract: The present invention provides methods and systems that provide for reliable, convenient, and noninvasive assessment of hydration status. The methods and apparatuses can use the temporal sequence of the aortic value opening and closing along with the user's body position to derive parameters that determine the hydration status of the user. The user can use this information to make near-term lifestyle changes that can improve physical performance, health, and general wellbeing.

Abstract: An adjustable weight exercise system is provided. A permanent weight assembly and a plurality of interlocking weights are provided. A base comprises an interlocking weight carrier, wherein the interlocking weights are supported on the interlocking weight carrier and an interlocking weight selector, wherein the interlocking weight selector is adapted to cause interlocking weights to be set to be locked to the permanent weight assembly while the permanent weight assembly is not on the base, wherein placement of the permanent weight assembly on the base causes interlocking weights that are set to be locked to the permanent weight assembly to be locked to the permanent weight assembly, and wherein placement of the permanent weight assembly on the base does not cause interlocking weights that are not set to be locked to the permanent weight assembly to be locked to the permanent weight assembly.

Abstract: A concentrate adaptor for a vaporizer device includes a reservoir and a base. The reservoir holds a concentrate. The reservoir is positioned within a vessel of the vaporizer device and is heated by a heating element of the vaporizer device to transfer heat to the concentrate, thereby generating an aerosol for inhalation by a user. The reservoir includes a sidewall surrounding an interior volume of the reservoir. The reservoir also includes a capillary structure positioned along the sidewall configured to direct the concentrate to the sidewall to be heated by the heating element.

Abstract: Aspects of the disclosure provide methods, apparatuses, and systems for providing variable strength mixtures of fluids. In an aspect of the disclosure, a fluid combining device allows for the relative volume of a first liquid to be varied with respect to a total volume of fluid being delivered to a user (such as a combination of two or more liquids), which in turn changes the fluid ratios.
