摘要： A sunlight exposure indicator device is disclosed that can determine the amount of time (e.g., hours) of PAR sunlight that occurs in a specific area for the optimal growth of a plant, as corresponds to the plant industry common designations of Full Shade, Partial Shade, Partial Sun and Full Sun. These designations can be used to determine plant selection for all types of plants including grasses, shrubs, flowers, vegetables and herbs, and trees. This device utilizes irreversible, slow-reacting, photochromic pigments applied to a substrate. Using multiple instances of this device will allow someone to easily test and accurately determine the amount of PAR sunlight (hours) received during a one-day sunlight cycle in multiple spots simultaneously. The sunlight exposure indicator device is a one-time-use, non-electronic, disposable device.

摘要： The present invention provides an ultraviolet-sensing member in which it is easy to determine whether an irradiation amount which inactivates the novel coronavirus has been irradiated, and an ultraviolet-sensing kit. In the ultraviolet-sensing member of the present invention, in a case where, using a KrCl excimer lamp as a light source, the ultraviolet-sensing member is irradiated with light through a filter which substantially shields light having a wavelength of 230 to 300 nm until an irradiation amount of light having a wavelength of 222 nm reaches 3 mJ/cm2, and using a spectrophotometer Spectrolino (GretagMacbeth AG), optical densities of predetermined colors are measured with the ultraviolet-sensing member before the light irradiation and the ultraviolet-sensing member after the light irradiation, the optical densities show a predetermined value.

摘要： The present invention is directed to methods and related systems for evaluating and demonstrating various performance characteristics of one or more dental curing lights. The method and system employs a performance evaluation member (e.g., in the shape of a disc) comprising a carrier material (e.g., any of various suitable polymeric materials) and a color-changing material on or within (e.g., impregnated within) the body material. A user is able to use the performance evaluation member to demonstrate and evaluate performance characteristics relating to the presence of particularly desired wavelengths within the light emitted by a dental curing light, footprint size and shape of emitted light, uniformity of intensity within the emitted footprint, as well as relative intensities of desired wavelengths provided by two or more dental curing lights.

摘要： Disclosed is a device for monitoring one or more of integral value of time and temperature, UV light exposure and a pre-determined temperature of an item. The device is useful for monitoring items or materials which are sensitive to time-temperature, UV light and/or a pre-determined temperature. Radiation sensitive devices such as self-indicating instant radiation alert dosimeters (SIRAD) can be accidentally, inadvertently or intentionally over exposed to time-temperature, UV light and a pre-determined higher temperature. Such over exposure can provide a false positive or false negative signal. A device based on polymerization of diacetylenes and melting of partially polymerized diacetylenes, both of which are associated with color changes, are proposed as false positive, false negative, and tamper indicator.
