Patent attributes
A mobile device can wirelessly connect, using transceivers, to a medical item and a wristband worn by a user. The mobile device includes a software application enabling a user to input distance thresholds. The wristband can also include a software application enabling a user to input distance thresholds. Both the mobile device application and the wristband application can monitor signals between the medical item and wristband. In another system, a medical item distance alert system can include a plurality of medical items. In another system, a mobile device is not in communication with the wristband or medical items. The wristband software application can monitor signals between medical items and provide alerts in the absence of another mobile device. Preferably, ultra-wideband (UWB) and Bluetooth transceivers can be implemented to provide accurate distance estimates with low power usage.
