Abstract: A mechanical robot can have a GPS receiver for localization, to enable it to navigate and/or perform location-specific functions. Also, the robot can be caused to ambulate in a location, taking pictures of guests and/or sounding an alarm if an unknown person is imaged by a camera on the robot. Further, the robot can be given a voice message for a recipient, and then ambulate around until, using face or voice recognition, it recognizes the intended recipient and delivers the message, e.g., aurally using a speaker.

Abstract: A system and method are described for activating programming downloaded to electronic devices. The method involves the generation of an encrypted (or encoded) activation key which is produced in response to the network address (i.e. media access control (MAC) address) of the electronic device to which the download is directed. Programming can only be activated within the electronic device upon a match being detected between the activation key and the network address of the electronic device. Typically, the programming would be downloaded from a web site, such as from a manufacturer of the electronic device, in exchange for receipt of a payment preferably executed as an online financial transaction. The system and method prevent the copying of downloaded programs for a given electronic device for use by other users.
