摘要:
A portable message device includes a base having at least one wheel providing portability for the portable message device, and a base access panel which in an open position provides access to an internal base cavity. A communication feature includes a message portion providing a predetermined message saved in a memory. A sensor provides indication of the proximity of a person to the portable message device. A processor is connected to the sensor and the memory. The processor actuates the communication feature upon sensing the proximity of the person. A power source positioned substantially within the internal base cavity provides electrical power to operate the communication feature and the sensor, the power source being accessible by opening the base access panel.
