Abstract: In one example, a system includes one or more personal protective equipment (PPE) devices each configured to be worn by a worker, the PPE devices each including one or more sensors that generate activity data indicative of activities of workers operating within one or more work environments. The system also includes a computing device, the computing device configured to: identify, based at least on the activity data, a plurality of clusters of one or more entities, wherein each entity of the entities is associated with one or more of the workers; and output an indication of a difference between performance by a target entity with respect to safety events and performance by the cluster that includes the target entity with respect to safety events.

Abstract: Systems and methods for generating random bits by using physical variations present in material samples are provided. Initial random bit streams are derived from measured material properties for the material samples. In some cases, secondary random bit streams are generated by applying a randomness extraction algorithm to the derived initial random bit streams.

Abstract: A display system includes a switchable display screen comprising a first transparent substrate, a first transparent conductive layer disposed upon the first transparent substrate, a second transparent substrate, and a second transparent conductive layer disposed upon the second transparent substrate. The display screen further includes a polymer-stabilized cholesteric texture layer and spacer elements disposed between and in contact with the first transparent conductive layer and the second conductive layer. The display screen comprises a plurality of addressable regions, each region capable of being switched from a transparent state to a diffuse state.

Abstract: A system for human interaction based upon intention detection. The system includes a sensor for providing information relating to a posture of a person detected by the sensor, a processor, and a display device. The processor is configured to receive the information from the sensor and process the received information in order to determine if an event occurred. This processing includes determining whether the posture of the person indicates a particular intention, such as attempting to take a photo. If the event occurred, the processor is configured to provide an interaction with the person via the display device such as displaying a message or the address of a web site.

Abstract: A system for projecting changeable electronic content across multiple display surfaces. The system includes display surfaces arranged at a non-zero angle with respect to one another, such as three orthogonal display surfaces in the corner of a rectangular shaped product container. Changeable electronic content, including video and digital still images, is converted such that, when the projector receives and projects the content to the multiple display surfaces, the content is displayed undistorted to a viewer.
