Abstract: Various embodiments of a voltage detection device and of related safety systems are provided. In various embodiments, the voltage detection device is configured to couple to safety headwear, such as via the one or more housing(s) of the voltage detection device coupling directly to the safety headwear or the voltage detection device coupling to an adaptor mounted to the hard hat.

Abstract: A display includes a plurality of light emissive panels. Each light emissive panel is flexible, has a light emissive surface with a plurality of pixels emitting light, has side edges, and is adjacent to other light emissive panels. The light emissive panels are in a flexed arrangement such that a total light emissive surface includes individual of the light emissive surfaces having a substantially full sphere surface or partial sphere surface shape.

Abstract: A touchscreen display may include display chassis, a touchscreen sensor, and filters. The touchscreen sensor may include row conductors and column conductors spanning a display surface. Each of the filters may be coupled to one of the row conductors or the column conductors such that the row conductors and the column conductors are coupled to the filters. Each of the filters may be grounded to the display chassis. Each of the plurality of filters may be configured to allow a touchscreen sensor frequency band of interest to pass through said filter such that the touchscreen sensor is configured to detect touches. Each of the filters may be configured to filter out electromagnetic interference (EMI) on frequencies other than the touchscreen sensor frequency band of interest and to ground the EMI to the display chassis. The touchscreen sensor and the filters may form an EMI shield across the display surface.

Abstract: A polyhedral display system is disclosed. The polyhedral display system may include three or more flat-panel displays shaped as polygons and connected to form a non-planar polyhedral display surface. Further, at least one of the three or more flat-panel displays may be shaped as a non-rectangular polygon. The polyhedral display system may further include a controller coupled to the flat-panel displays. The controller may receive visual content, divide the visual content into three or more segments for display on the three or more flat-panel displays based on their relative positions, and provide data signals to the three or more flat-panel displays based on the three or more segments for displaying the visual content.
