Described are a system and method for securely distributing session keys over a network to each node in a chain of computer system nodes. The pixel reading circuits of the imager are adapted to process pixel signals corresponding to the integration periods in parallel. The system of the present invention includes an automated camera management system for controlling the camera system and an analysis module determining the location of meeting participants in the meeting environments. Using transmission capabilities, the water treatment system may transmit collected data to a remote server for, inter alia, storage, aggregation, filtering, andor analysis. One of the nickel-chromium-nitrogen layers is directly formed on the bonding layer. The sensor assembly measures at least two operational characteristics and generates corresponding operational characteristic signals.
