A secure messaging system and method includes receiving an encrypted message, the message having been encrypted using a token of a corresponding pervasive device; wirelessly verifying the presence of the pervasive device; and, if the presence can be verified, decrypting the message using the token. The verification step can include the steps of establishing a wireless link with the pervasive device; and, querying the pervasive device over the wireless link. The establishing step can include the step of establishing a Bluetooth link with the pervasive device. Furthermore, the querying step can include the step of requesting geographic coordinates which locate the pervasive device.

Enhanced message security

A method of detecting hazardous conditions within an underground environment can include obtaining acceleration information at a plurality of communication nodes distributed throughout the underground environment and propagating the acceleration information among selected ones of the plurality of communication nodes to an analysis node. An indication of a hazardous condition within the underground environment can be identified from the acceleration information collected over a period of time. If an indicator is identified, a notification of the hazardous condition can be provided.

Detecting hazardous conditions in underground environments

A secure messaging system and method. The method can include the steps of receiving an encrypted message, the message having been encrypted using a token of a corresponding pervasive device; wirelessly verifying the presence of the pervasive device; and, if the presence can be verified, decrypting the message using the token. The verification step can include the steps of establishing a wireless link with the pervasive device; and, querying the pervasive device over the wireless link. In particular, the establishing step can include the step of establishing a Bluetooth link with the pervasive device. Furthermore, the querying step can include the step of requesting geographic coordinates which locate the pervasive device.

A system for detecting defects in a fluid delivery line is provided, the system comprising a plurality of sensors disposed in a fluid delivery line, wherein each one of the plurality of sensors comprises a mote coupled to a plurality of sensing devices disposed in a film system, wherein a first mote being configured to receive data from at least one second mote, wherein the first mote being further configured to transmit data collected from the plurality of sensing devices coupled the first mote and received data from the at least second mote, a communications hub configured to receive sensor data from at least one mote, and a processor coupled to the antenna, the processor being configured to analyze sensor data received from the at least one mote.
