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.

Abstract: A voltage transducer for a lighting system can include an input operable to receive an alternating current input power. The voltage transducer can include a current sink circuit operable to provide a current sinking output. The voltage transducer can include one or more control devices configured to determine a magnitude associated with the alternating current input power. The one or more control devices can be further configured to control the current sink circuit to adjust the current sinking output based, at least in part, on the magnitude of the alternating current input power.
