    Abstract: In some implementations, a monitoring device associated with a lanyard device may detect that a portion of a strap of the lanyard device has extended from a strap core of the lanyard device. The monitoring device may generate a notification that the portion of the strap has extended from the strap core, wherein the lanyard device is configured to anchor the user to a support structure via the strap, and wherein a sensor within the monitoring device is configured to monitor a position of the strap relative to the strap core. The monitoring device may transmit, to a management device, the notification that the portion of the strap has extended from the strap core, wherein the notification includes an identifier associated with the lanyard device to alert the management device of a hazardous event involving the user.

    Abstract: Systems and apparatuses for dual-mode pressure-sensing and illumination mats are provided. The systems include a surface that includes a plurality of row wires and a plurality of column wires forming intersection points. At the intersection points, the systems include a pressure sensor configured to sense a pressure exerted upon the surface and a light emitting diode (LED) connected in parallel. The systems include a controller coupled to the selector and configured to control operation of the surface, wherein the controller is configured to operate in one of a pressure-sensing mode or an illumination mode. When the controller is configured to operate in the pressure-sensing mode, the controller scans pressure values provided by the pressure sensors. When the controller is configured to operate in the illumination mode, the controller configures the surface to enable the LEDs in accordance with an illumination pattern.
