Systems and methods are provided for at least partially automating content generation of blog entries chronicling an entity’s interaction with a multiuser environment. When inflated the airbag is clamped between two points on the vehicle body which are separated from each other in the longitudinal direction of the vehicle. Also provided is a respiratory waveform recognition system. A video digital to analog converter converts the decoded video bitstream to an analog video signal that is optionally decrypted by a video analog decryption unit. The device may further include characterization of the environment based on processing of the ambient noise within the environment and several inputs including: manual inputs, real time clock, light sensing, temperature sensing, cellular receiver indications, motion sensing, caller identification, global positioning system data, and radio link reception. The compounds of the present invention may be incorporated in compositions and kits.
