  • Umbrella with wireless tether
    Patent number: 10002516
    Abstract: The umbrella cooperates with a software application adapted to run on a mobile communications device wirelessly synced to the umbrella. The umbrella includes a communications module adapted to transmit a wireless beacon signal in response to the detection of movement of the umbrella. The software application detects the beacon signal when the smartphone is within range of the umbrella and generates an alert when the beacon signal is no longer being received, indicating that the smartphone is no longer within range and the umbrella has been forgotten. In one embodiment, the GPS application on the smartphone is cause to generate a location update signal in response to detection of the beacon signal such that the software application can run continuously in the background on the smartphone to ensure timely range entry and exit notifications.
