Abstract: A method and a system for providing convertible or interactive messaging between two or more users is provided. In an embodiment, a user sends a convertible message to another user. Such convertible messages can be sent using a communication means having two or more fields, ports, or the like. One of the fields, ports, or the like is used to identify the transmission as a convertible message. Another of the fields, ports, or the like is used to relay the text, icon, etc. of the message. Upon recognition of the convertible message, the receiving device allows for the display of the convertible message. The receiving user may manually accept to view the convertible message, and/or may view/not view the convertible message automatically upon receipt due to predefined rules.

Abstract: Embodiments of the present invention apply wavelets to radio frequency (RF) signals to extract specific characteristics (e.g., jitter, phase variations, frequency variations) so that their timing, phase, and frequency components can be characterized. In one embodiment of the present invention, a Haar wavelet is used to extract timing characteristics. In another embodiment, a Morlet wavelet is used to extract phase characteristics. In still another embodiment, a Morlet wavelet is used to extract frequency characteristics.
