    Abstract: An apparatus for generating alerting sounds and broadcasting the same into the interior of a building so that an occupant can be made aware of an emergency, warning, etc. or of the building for various other purposes such as to greet a visitor or accept a package or sign documents from a transporter drone or robot. The sounds are generated by an exciter feature of a transducer held in a case, the exciter feature being able to be pressed against an exterior surface. The transducer vibrates its exciter feature in correspondence with audio signals transmitted to the transducer to broadcast corresponding sounds into the interior of the building by resonance induced in the door or other building member by the vibrating exciter feature. The sounds may resemble conventional alerting sounds such as a knocking or ringing sounds, and/or can be a spoken message either prerecorded in an audio source or created contemporaneously by being spoken by a user into a microphone. The device may be hand carried door to door as by delivery personnel and emergency workers and used to effectively alert occupants and eliminate the need for hand knocking or yelling a message through the door, or is mounted to a drone, robot, or other transporter device, or to some other portable device. The device may also be used to broadcast sounds in an open area by holding the exciter feature against a sign board or other structure in an open area.

    Abstract: A wall-drawing hovering device (WDHD) is provided. The WDHD comprises an unmanned helicopter configured and operable for flying and hovering while being disconnected from ground. The WDHD further comprises a mobilizing system comprising at least one motorized wheel. The mobilizing system is physically associated and carried with the unmanned helicopter and configured to drive the WDHD along a vertical surface when the WDHD hovers above ground. The WDHD further comprises a drawing system comprising a paint releasing member connected with a paint reservoir. The drawing system is carried with the unmanned helicopter and configured to controllably release paint from the paint reservoir through the paint releasing member. The WDHD is thereby configured to hover above ground next to a vertical surface such as a wall, so that the mobilizing system frictionally attaches to the vertical surface thereby enabling driving the WDHD along the vertical surface. The WDHD is further configured to draw on the vertical surface by controllably releasing paint from the paint releasing member.
