Abstract: In one aspect, the disclosure relates to anodically coloring organic electrochromic materials as discrete chromophores. The chromophores are UV absorbing in the neutral state and upon oxidation form vibrantly absorbing, colored radical cation and dication species. In an aspect, the disclosed materials include UV absorbing discrete chromophores based on a 2-thiomethyl-dioxythiophene coupled to a triphenylamine or carbazole unit. In another aspect, consideration of steric effects and tuning substituent pattern can lead to new cation radicals that are highly saturated in the colored state and have increased color vibrancy. The chromophores and materials containing the same can be used in electrochromic color-to-clear switching devices including, but not limited to, windows, displays, signs, goggles, glasses, and the like.

Abstract: Methods and systems for predicting injury risk include generating state sequences that precede a hazard event based on information regarding a user's state. A cognitive suite of workplace hygiene and injury predictors (WHIP) is generated based on the state sequences using a processor, wherein the cognitive WHIP predicts a degree of risk correlated with each particular user state sequence. A risk heat map of a workplace is generated based on the cognitive WHIP that encodes regions of greater and lesser risk. An ameliorative action is triggered when a user moves into an area of high risk based on the heat map.

Abstract: Social media databases are minded for data related to a subject person. The data in indicative of a level of ultraviolet light exposure of the subject person. An ultraviolet violet exposure profile for the subject person is generated based upon the data and a health assessment report provided. The data may include timestamped images of the subject person and other related persons. The skin characteristics within images are analyzed to determine an ultraviolet light exposure level for the subject person from each image. The skin characteristics may include skin color, freckling and blemishing. The ultraviolet light exposure profile may be developed over an extended interval based upon the image timestamps. The health report may be used to mitigate risks, such as skin cancer, associated with exposure to ultraviolet light.
