ABSTRACT:
The present invention is for an umbrella with a device, called the umpod, built into the handle of the umbrella. When detached from the handle, the umpod serves as a receiver of a pulsating RF signal, or other electronic communication, sent from the handle of the umbrella. There is an transmitter located in the handle of the umbrella and a receiver located in the umpod. When the umpod is separated from the umbrella handle, the umpod is activated and when separated by more than a preset distance, the receiver senses the diminished strength of the communication signal and the umpod automatically goes into “alert” mode. In “alert” mode, the umpod vibrates and/or beeps until the umpod is brought back within the range of the preset distance from the umbrella handle.
