The present invention relates to a vacuum cleaner having a steam cleaning function. A reconfigurable orthogonal frequency division multiplexing chip may be utilized in a mobile terminal to process received spatially multiplexed signals. Those include but are not limited to supplying power to a camera head that tilts and rotates, particularly at a remote location. The voice control program, in response to the response, automatically causes the second execution state of the application program having a second graphical display. The base can have a storage compartment for one or more latch assemblies used to latch the base to the vehicle seat anchorages. The security system also supports RFID transponders that may be carried by persons or animals, of that may contain a button used to signal an event such as an emergency.
