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.
