Abstract: Secure wireless data prefetching and delivery is provided. A first demand is received from a first requesting device, requesting a first data file from the central agent, the first requesting device storing first cache data including a key and a first portion of the first data file. A second demand is received from a second requesting device, requesting a second data file from the central agent, the second requesting device storing second cache data including the key and a second portion of the second data file. A function is generated configured to allow the first requesting device to generate the first data file from the first portion and to allow the second requesting device to generate the second data file from the second portion. The function is broadcast to the first and second devices, responsive to the first and second demands.

Abstract: Autonomous management of wireless connectivity of priority response vehicles is provided. It is received, from a communications network including a plurality of access points, the access points configured to provide communications services to priority vehicles and non-priority vehicles, locations of the priority vehicles over the communications network. A SON server is utilized, in communication with the plurality of access points, to optimize wireless connectivity for the priority vehicles. It is received, by an enhanced vehicle management system (EVMS) server, in communication with the SON server, network quality information from the SON server. The priority vehicles are routed based on the network quality information.

Abstract: Electron capture detector for use with an effluent stream from a gas chromatograph includes a non-radioactive electron source means and an adjacent ionization chamber in which electron capture take place. The detector comprises two partial chambers, of which one contains the electron source, and the other contains connections for input and output of analysis gas as well as a collector electrode for detecting ions. The collector electrode and the electron source are each of cylindrical configurations, and are coaxially aligned but are spaced apart with respect to each other. The electron current to the collector electrode provides an indication of the presence of electronegative constituents in the gas passing into the second partial chamber.
