A fact extraction tool set finds and extracts targeted pieces of information from text using linguistic and pattern matching technologies, and in particular, text annotation and fact extraction. The signals from the radiation detector are analyzed into a multiplicity of energy channels, for example with a multi-channel analyzer, the counts in at least two energy windows being used to determine the shapes of the low-energy tails of the peaks of the naturally occurring radio-nuclides ThC and RaC, so their effects can be eliminated. A brake light supply line may be used as the second supply line providing the current andor voltage supply line for the electronic andor electric components of a braking device of a vehicle trailer when the supply of the braking device has failed. The held portion includes a toner outlet for discharging the toner contained in the container body, and an openclose member for openingclosing the toner outlet in synchronization with an attachmentdetachment operation tofrom the toner-container holder. Each ribbon includes one or more nanotubes. This system includes one or more robotic arms that can be attached to the operating table.
