Abstract: In general, techniques are described for a personal protective equipment (PPE) management system (PPEMS) that uses images of optical patterns embodied on articles of personal protective equipment (PPEs) to identify safety conditions that correspond to usage of the PPEs. In one example, an article of personal protective equipment (PPE) includes a first optical pattern embodied on a surface of the article of PPE; a second optical pattern embodied on the surface of the article of PPE, wherein a spatial relation between the first optical pattern and the second optical pattern is indicative of an operational status of the article of PPE.

Abstract: Techniques are described in which articles (e.g., security documents, traffic signage and personal protective equipment) are formed to include an infrared absorptive material. In some instances, the infrared absorptive material includes a reduced tungsten oxide, such as cesium tungsten oxide, calcium tungsten oxide, potassium tungsten oxide, or the like, and exposed to radiation such that one or more regions of the security document has a modified appearance, thereby providing a visual marking or information on the article. Example articles include at least one layer including a polymer and an infrared absorptive material including a reduced tungsten oxide. The layer includes a radiation-treated region that exhibits a first appearance under visible light and at least one non-radiation-treated region that exhibits a second, different appearance under visible light. The at least one radiation-treated region may be formed by exposing the at least one radiation-treated region to infrared light to change at least one property of the reduced tungsten oxide in the radiation-treated region compared to the reduced tungsten oxide in the non-radiation-treated region. The first appearance may be whiter than the second appearance.

Abstract: The disclosed light directing article comprises a structured layer, an adhesive sealing layer, and barrier elements. The structured layer comprises multiple microstructured elements that are opposite a major surface. The adhesive sealing layer has a first region and a second region. The second region is in contact with the structured layer. The barrier element are at the first region. The first region with the barrier element and second region have sufficiently different properties to form a low refractive index layer between the adhesive sealing layer and the structured layer. The barrier element comprises a crosslinked polymeric matrix having a modulus of elasticity less than 4.4 GPa.
