Patent attributes
A network hub has a housing that contains a computer processor and a computer memory operably connected to a transceiver for communicating with a plurality of alert devices. The network hub also includes a speaker operably connected to the computer processor. The computer memory stores executable code that, when executed, enables the network hub to perform a process that includes the steps of: pairing one of the alert devices with the network hub via the transceiver for wireless communication; receiving data periodically from the alert device paired with the network hub, which may include the alert if the user requires assistance; determining if the alert device loses wireless communication with the network hub; and sounding an audible alert from the speaker of the network hub to alert the user that the alert device has lost communication with the network hub.
