Abstract: Head thermoregulatory apparatuses, related devices and methods, are disclosed herein. In some embodiments, a head thermoregulatory apparatus may include a core body temperature sensor; a head thermoregulatory device including a fluid pad, an input port, and an output port; a fluid device configured to heat or cool a fluid, the fluid device including the fluid, an input port, and an output port; fluid hoses between the head thermoregulatory device and the fluid device; a fluid valve coupled to the fluid hoses; and control circuitry coupled to the fluid valve and to the core body temperature sensor, wherein the control circuitry is configured to activate the fluid valve based on a determination that an absolute difference between a subsequent core body temperature and a baseline core body temperature exceeds a threshold. In some embodiments, the fluid device cools the fluid. In other embodiments, the fluid device heats the fluid.

Abstract: Disclosed is a canning funnel with an integral headspace gauge, the canning funnel includes a receiving bowl, an outer base, and a positioning portion which when used with a canning jar, protrudes into the opening of the canning jar to guide foodstuffs from the receiving bowl into the canning jar. The positioning portion is formed with horizontal steps that form a headspace gauge, the steps indicating predetermined distances from the top edge of the canning jar so that when in use, liquid or foodstuffs can be added until a required amount of space is formed between the foodstuffs or liquid and the top edge of the canning jar. The horizontal steps being viewable by a user when the canning funnel is positioned on a canning jar for use.
