Insulin pens must be kept between 15° and 30° Celsius to ensure safe and effective injection. An Israeli company has developed a cap that combines phase change material with monitoring electronics to keep these pens from overheating in hot environments.
U.S. patent 20170150822 (applicant Tempur-Pedic Management LLC, Lexington, Ky.):
"A support cushion cover assembly for removing humidity and heat from a contact surface of a support cushion is provided. The support cushion cover assembly comprises a support cushion cover that includes an upper panel having a top surface, a bottom surface, and a middle spacer layer positioned between the top surface and the bottom surface. The support cushion cover further includes an amount of hygroscopic material and at least one flexible tube that defines a plurality of fenestrations. Each fenestration is in fluid communication with the middle spacer layer of the upper panel. An air pump is further included in the cover assembly and is operably connected to the flexible tube, such that an amount of air is delivered into the flexible tube and the middle spacer layer of the cover. Methods for removing humidity from a contact surface of a support cushion are also provided."
U.S. patent 20170135884 (applicant Hill-Rom Services Inc., Batesville, Ind.):
"Embodiments provide a person support system including support pads having cooling features. According to one embodiment, a person support system may include a longitudinal frame comprising at least one side rail. A support pad may be positioned on the longitudinal frame. The support pad may comprise a thermally conductive core portion comprising a support matrix and at least one thermally conductive element. ... The thermally conductive core portion may be constructed from different phase change materials (or even different combinations of phase change materials) to achieve different degrees of cooling."
U.S. patent application 20170141724 (applicant GlassPoint Solar Inc., Fremont, Calif.):
"A method for delivering heat to a subsurface location, comprising: transferring solar energy to a working fluid via multiple solar collectors; directing the working fluid through a loop to at least partially transfer energy from the working fluid to a subsurface heating well, wherein the loop at least partially extends through the subsurface heating well, and wherein the subsurface heating well contains a thermal energy storage substance (TESS) positioned between the working fluid and an outer casing of the subsurface heating well; and controlling a flow of the working fluid to cause the TESS to undergo at least a partial phase change at least one phase change temperature or a partial chemical change at at least one chemical change temperature."
• Thermal Energy Service Solutions, maker of a PCM-based "plug-and-chill" refrigeration system for delivery trucks, is profiled in this month's issue of Forbes India. The system's heat exchanger is designed to keep the refrigerator on the truck within the optimal temperature range for a full day’s operation without drawing power from the engine. The heat exchanger can be fully charged in about six hours at any power outlet.
• C-Therm Technologies will be among the exhibitors the Techtextil North America trade show in Chicago June 20-22. The company will demonstrate its non-destructive TCi Property Analyzer, which is designed to characterize the thermal performance (the “warm feel” or “cool touch”) of textiles, fabrics and apparels.
• Terrafore Technologies of Minneapolis is one of seven small businesses recently selected to collaborate with researchers at Argonne National Laboratory as part of the Department of Energy's Small Business Vouchers program. Terrafore and Argonne will test the reliability of phase change salt capsules for a compact high-temperature thermal energy storage system for concentrated solar power.
• SpecialChem is offering an online course titled "How to Search & Map U.S. Patents for Patentability." The 90-minute course, scheduled for June 28, is designed to for R&D people "looking to avoid patent infringement by enhancing their patent searching and mapping skills." The cost for three attendees on one connection is 300 euros.

More than a thousand of your peers have joined a LinkedIn group devoted to the discussion of phase change material and thermal energy storage. The Phase Change Matters group is an interactive complement to the award-winning blog and newsletter of the same name.
You are invited to join the group and connect with PCM and TES experts from around the world. This week we welcome Martin Heinemann, head of customer service at va-Q-tec AG, Würzburg, Germany; Nandi Lwin, who is pursuing a master's degree in materials science and engineering at Mahidol University, Bangkok, Thailand; Francisco Tamayo, a student at the Institute of Renewable Energy, National Autonomous University of Mexico, Morelos, Mexico; and Wulf Luebbe, planning and optimization manager, Sasol Wax GmbH, Hamburg, Germany.
