    Abstract: The present disclosure provides embodiments of mobile devices designed to be worn by a person and configured to detect when another mobile device is within a predefined distance and to provide the wearer with an indication that another mobile device is within the predefined distance. The mobile device includes a sealed housing, a clip member, a UWB detector and at least one indicator. The housing has a front housing portion, a rear housing portion and at least one cavity for receiving internal components. The clip member includes a mounting bracket used to affix the clip member to either the front housing portion or the rear housing portion, and a clip is used to permit mobile device to be worn by a person. The UWB detector circuit is located within the at least one cavity and receives signals from at least one other mobile device. The UWB detector circuit also calculates a distance between the mobile device and the at least one other mobile device. The at least one indicator is used to provide at least an audible, haptic or visual indication when the distance between the mobile device and the at least one other mobile device is calculated to be within a predetermined distance.

    Abstract: An emergency lighting system including a light source, a variable constant current drive, an emergency alarm, and a controller. The light source includes a first light channel that produces light at a first correlated color temperature and a second light channel that produces light at a second correlated color temperature that is less than the first correlated color temperature. The variable constant current drive is configured to supply DC current to the first light channel and the second light channel. The emergency alarm is configured to be triggered upon detecting the presence of an emergency condition. The controller is configured to determine whether the emergency alarm is triggered, increase the DC current supplied to the first light channel when the emergency alarm is not triggered, and decrease the DC current supplied to the first light channel when the emergency alarm is triggered.

    Abstract: Devices, systems, and methods for support structure inspection are provided. In one example implementation, a system can include one or more sensors configured to obtain data associated with a condition of a support structure, such as a utility pole. The system can include one or more processors. The system can include a communication circuit operable to communicate a data packet to a remote device. The data packet can include a payload generated based at least in part on the data associated with the condition of the utility pole. The system can include a power source operable to provide electrical power to the one or more sensors, one or more processors, and the communication circuit.

    Abstract: Tool monitoring systems and beacon devices used in the tool monitoring systems are provided. The tool monitoring systems permits one or more beacon devices to upload tool information to a cloud-based computing system either directly or indirectly. Direct communication between the beacon devices and the cloud-based computing system 12 utilizes a communication module and a server. Indirect communication between the beacon devices and the cloud-based computing system utilizes a mobile application running on a mobile computing device or platform and a web services running on the server. The beacon devices are worn by a tool user or installed in a fixed location and communicate with one or more tools to retrieve tool information from the one or more tools and upload the tool information to the cloud-based computing system's database.
