Abstract: An equipment security system includes one or more sensors or optical recording devices disposed on or inside a cargo container. A computing device receives data from the one or more sensors or optical recording devices, determines whether an event has occurred at the cargo container, determines a geofence associated with the cargo container, and selects or configures a dynamic script including instructions that specify whether to begin recording an event occurring at or inside the cargo container, whether to record the event in an overwritable, local memory associated with at least one of the one or more sensors or optical recording devices or the computing device, parameters that govern how data associated with the event will be recorded, and whether to upload the data from the local memory to a remote server.

Abstract: A reactor chamber forms part of an exhaust system of an internal combustion engine. Within the chamber are electrodes between which there is disposed a bed of active material through which, in use, the exhaust gases pass. In the presence of an electrical discharge, driven by an electrical voltage applied across the electrodes, the active material has a catalytic action in the reduction of nitrogenous oxides in the exhaust and also acts to remove hydrocarbons from the exhaust gases.

Abstract: A reactor (1) particularly for the plasma treatment of internal combustion engine exhaust gases, in which a power supply (10) and a reactor bed (2) of the dielectric barrier discharge type are connected directly and enclosed in an earthed metal chamber (17) which both isolates the high voltage power supply and acts as a Faraday cage preventing the emission of electromagnetic radiation from the power supply or plasma.

Abstract: In a non-thermal plasma reactor (300), at least a component of the active material (320) is selected or modified to provide the capability to adsorb or trap a predetermined chemical species in the gas flow thereby to increase the effective residence time of said species relative to the residence time of unadsorbed species in the gas flow.

Abstract: Hydrogen is generated from hydrocarbon fuel by a reforming reaction in a reactor (11) in which gaseous hydrocarbon and reforming reaction agents are subjected to the formation of a plasma having an electric field strength within the plasma exceeding 10,000 volts per centimetre, preferably at least 20,000 volts/cm, more preferably at least 40,000 volts/cm or even 80,000 volts/cm. The apparatus has electrodes (14, 15, 16) and dielectric material (22-27), the configuration of which allows for plasma having the electric field strength defined above.
