Abstract: A system (160) and method (400) is provided for validating a location of a tracking device. The method can include monitoring (902) a set of signal strengths (600) to one or more personal area networks (104) and one or more cellular towers (110), generating (906) a Radio Frequency Time Profile RFTP (700) from the set of signal strengths, comparing (908) the RFTP o coverage variation limits (720) of one or more pre-calibrated paths, and signaling (910) an alert if the set of signal strengths are not within the coverage variation limit of the one or more pre-calibrated paths. The RFTP is a time series of the signal strengths between the tracking device and the one or more PANs resulting from a change in location of the tracking device.

Abstract: A device (102) that can perform voice recognition operates with a removable media or memory (104) that is used to store information records (126). To save memory space in the removable media, voice recognition tags (118), used to perform voice recognition, are not stored in the removable media, but are stored in the device. Since the media is removable, the device must check to make sure the records stored in the media are usable with the voice recognition tags. This is accomplished by generating a key (306) whenever a new voice recognition tag is trained (304). The key is stored in the device, or in the media, or both. Upon initialization of the device, (202), the device searches (206) the media for records and checks (210) to see if the key corresponding to the record matches any keys in the device. When a match is found the record is associated (214) with the corresponding voice recognition tag. Voice recognition tags with no corresponding records are deleted or ignored.

Abstract: Graphical display data representing an image for display is packetized for wireless transmission. At least one command for displaying the image from the data is within the packet. The command is used to display the image, as represented by the packetized data, in related configurations to create an animated display or at predetermined times or intervals to make the image appear spontaneously or be removed after a predetermined period of time for later display or are erased. Transmission of the packetized data occurs when the receiving devise is idle. The transmission of the packets may be interrupted by a present need to establish a communications channel with the receiving device, for example for voice communication or for transmission of hyperlinked data. A handshake protocol is used to assure the parts of the packetized data are successfully downloaded.
