Methods and systems for measuring the temperature of a sample can include the use of one or more illumination sources and a sample containing thermochromic material. One or more detectors are operable to detect two or more signals indicative of a component of an illumination facilitated by the illumination source(s) and scattered at two or more angles with respect to the sample containing the thermochromic material, wherein the signals are converted to a temperature.

A nanocalorimeter device includes a substrate having test cells, each test cell comprising a sample location. Each sample location includes a reaction surface suitable for an enthalpic reaction of constituents of liquid droplets, droplet movement and configured to merge the droplets, and a layer of thermochromic material thermally coupled to the reaction surface. The thermochromic material is configured to exhibit a spectral shift in light emanating from the thermochromic material in response to a change in temperature of the merged droplets.

A system for determining the profile of a laser beam includes a detector having a thermochromic liquid crystal film (TLCF) in thermal communication with a heat spreader and a thermoelectric cooler. The liquid crystal film has a thermochromic response such that heating of the film by a received laser beam creates a detectable color response at the film. The system also includes an image sensor and a controller configured to output an operating current for the TEC and receive images from the sensor. The system can selectively vary the temperature set point of the TEC to change the steady state temperature of the TLCF to examine the full intensity profile of the received beam even when the temperature response bandwidth of the TLCF is too narrow to display the full beam profile in a single color spot.

The present invention pertains to an integrated wound dressing device for treatment of an insertion site of percutaneous and drug delivery devices. The integrated wound dressing device preferably comprises a transparent film layer having a bottom side, a top side and a perimeter. The bottom side is coated with an adhesive impregnated with an antimicrobial agent. The transparent film has a radius cutout between a central opening and the perimeter. A liquid crystal temperature sensitive film with an adhesive placed on the top side of the transparent film layer is preferably near and around the central opening. The dressing also has a layer of double folded release paper below the bottom side of the transparent film layer. The preferred TLCs used are cholesteryl esters with a preferable temperature detection range of 35-40° C. The preferred antimicrobial agent is chlorohexidine gluconate (CHG).

A temperature indicating label for perishables includes a protective layer, a thermochromic liquid crystal layer, a silver-plated layer, an adhesive layer, and a release liner. The thermochromic liquid crystal layer is perimetrically superimposed onto the silver-plated layer. The protective layer is perimetrically superimposed onto the thermochromic liquid crystal layer. The protective layer and the silver-plated layer are oppositely positioned of each other about the thermochromic liquid crystal layer as the thermochromic liquid crystal layer displays a color-coded reading to demonstrate the measured temperature of the perishables. The adhesive layer is superimposed onto the silver-plated layer thus allowing the label to be attached to the package or the container of the food. The adhesive layer is oppositely positioned to the thermochromic liquid crystal layer as the release liner is perimetrically attached to the adhesive layer.

The present invention comprises a duplex thermal transfer pack. The pack includes a large bag containing many smaller sub bags. Each sub bag contains plain water. The volume within the large bag but outside the sub bags contains a second substance. This second substance freezes with a consistency akin to crushed ice or packed snow. The second substance allows the thermal transfer pack to remain malleable even when its contents are frozen.
