U.S. patent application 20190273295 (applicant Anhui Xinen Technology Co. Ltd., Anqing Anhui, China):

"Disclosed is a technique for managing the temperature of rechargeable cells. An energy storage device can include a plurality of rechargeable cells disposed within a housing and a material disposed within the housing so as to completely surround each of the rechargeable cells in a particular plane. The material can have a thermal characteristic such that the material remains a solid upon absorbing heat from the rechargeable cells by changing a crystal lattice structure. Intrinsic latent heat properties of the material result in absorption or release of heat to maintain a temperature of a rechargeable cell within a pre-defined temperature range. A regenerative mechanism including a heat pump coil can restore the material to a lower energy crystal lattice structure."

U.S. patent application 20190254362 (applicant Under Armour Inc., Baltimore, Md.):

"The present invention is directed toward an article of apparel effective to regulate the temperature of the wearer. In an embodiment, the article of apparel includes a base textile with a thermal regulation membrane. The thermal regulation membrane contains a plurality of system-reactive components selectively engaged heat and/or moisture. In an embodiment, the printed coating includes a cooling agent, a phase change material, and a heat dissipation material. In operation, the article of apparel is effective to delay/diminish the rise in skin temperature (compared to a garment lacking the membrane), increasing wearer comfort."

U.S. patent application 20190249058 (applicant Technogel Italia S.r.L., Pozzoleone, Italy):

"A method for the production of a temperature regulating polyurethane gel composition and corresponding articles includes fatty acid esters as a phase change material (PCM) directly incorporated in the fluid phase of a polyurethane gel without encapsulation. The liquid or melted PCM is solved in the polyol component of the gel and is able to crystallize and melt within the gel structure reversibly. The polyurethane gels are under-crosslinked and include an at least nominal three functional ethylene oxide-comprising alkylene oxide polyether polyol with 0 to 40% EO and an isocyanate with an effective functionality of from 1.5 to 3.5. The gels are useful in articles where the gel can be positioned close to the human body for temperature regulating purposes, and especially to improve the sleeping comfort of a resting person."

U.S. patent application 20190231121 (applicant Ember Technologies Inc., Westlake Village, Calif.):

"An infant bottle feeding system includes an infant bottle with a chamber that receives a liquid, heating or cooling elements operable to heat or cool liquid in the chamber and sensors operable to sense parameters of the liquid in the chamber. The system optionally includes an electronic base removably attached to a bottom surface of the infant bottle and operable to deliver power to electronics in the infant bottle. The system optionally includes a thermal cover that fits over the infant bottle and releasably couples to the electronic base to enclose the infant bottle, the thermal cover insulating the infant bottle and inhibiting heat loss of the liquid in the chamber. The electronic base delivers power to the heating elements and sensors in the infant bottle only when the infant bottle is on the electronic base. The infant bottle, thermal cover and electronic base define a single travel pack unit when coupled together."
