Abstract: A shoe degradation sensor assembly includes a first sensor disposed in or proximate to a material layer of a shoe between a foot space and an outer surface of the shoe, and an electrical contact assembly operable to removably electrically connect the shoe degradation sensor assembly to a reader. The material layer changes in at least one physical property with degradation to the shoe, and the first sensor is configured to indicate the changing physical property of the material layer thereby indicating a degree of degradation to the shoe.

Abstract: In some examples, a system includes an article of personal protective equipment (PPE) having at least one sensor configured to generate a stream of usage data; and an analytical stream processing component comprising: a communication component that receives the stream of usage data; a memory configured to store at least a portion of the stream of usage data and at least one model for detecting a safety event signature, wherein the at least one model is trained based as least in part on a set of usage data generated by one or more other articles of PPE of a same type as the article of PPE; and one or more computer processors configured to: detect the safety event signature in the stream of usage data based on processing the stream of usage data with the model, and generate an output in response to detecting the safety event signature.

Abstract: Gradient permittivity films are described. In particular, gradient permittivity films that include a first continuous matrix of a first component having a first relative permittivity and a second component disposed within the continuous matrix having a second relative permittivity. The first permittivity is greater than the second permittivity for at least one wavelength between 20 GHz and 300 GHz. Such films may be useful in improving the signal to noise ratio for transmitting and receiving units behind a protective cover.

Abstract: In some examples, a system includes a self-retracting lifeline (SRL) comprising one or more electronic sensors, the one or more electronic sensors configured to generate data that is indicative of an operation of the SRL; and at least one computing device comprising one or more computer processors and a memory comprising instructions that when executed by the one or more computer processors cause the one or more computer processors to: receive the data that is indicative of the operation of the SRL; apply the data to a safety model that predicts a likelihood of an occurrence of a safety event associated with the SRL; and perform one or more operations based at least in part on the likelihood of the occurrence of the safety event.
