Systems and methods for coexistence of WLAN and Bluetooth networks are described. The header includes a segment length field describing the length of memory reserved for the data record and the data record contains at least one data instance object. The batteries may be charged using wireless charging systems installed along the roads while the vehicle is in use on the road. The protective jackets can be formed in rigid, semi-rigid, or highly flexible polymer films, to protect the circuitry from the elements, CTE mismatches, shock and vibration loads and extreme g-forces. The threat agent is identified substantially coincident in time with the depositing of the sample of the threat agent onto the substrate. The card database is configured for storing data and the card data can be accessed via the point of service interface.
