Abstract: A velocity error signal generation method for controlling a velocity by comprising an actual velocity signal from an actual velocity generator with a command velocity signalfrom a command velocity generator includes removing a direct current component from the actual velocity signal, adding the direct current component of the command velocity signal to the alternating current component of the actual velocity signal, adding a minute voltage to the command velocity signal, subtracting the minute voltage from the command velocity signal, comparing a first signal obtained by adding the direct current component of the command velocity signal to the alternating current component of the actual velocity signal with a second signal obtained by adding the minute voltage to the command velocity signal, comparing the first signal with a thrid signal obtained by subtracting the minute voltage from the command velocity signal, and determining whether the actual velocity or the command velocity will be used an an input for generating a velocity error signal. In a velocity generating apparatus for realizing the method, when the difference between the actual and command velocity signals is outside a predetermined range, the actual velocity is regarded as being erroneously measured and is then replaced with the command velocity to detect a velocity error, thereby enhancing the reliability of a control system.

Abstract: A defense method and device against intelligent bots using masqueraded virtual machine information are provided. The method includes performing global hooking on a virtual machine detection request transmitted by a process, determining, on the basis of pre-stored malicious process information, whether or not the process transmitting the virtual machine detection request corresponds to a malicious process, and when the process is found to correspond to the malicious process as a result of the determination, determining that the process is generated by the intelligent bot, and returning the masqueraded virtual machine information to the process.

Abstract: A terminal discriminating apparatus and a terminal discriminating method using the same are provided. The terminal discriminating apparatus includes: a measurement unit for measuring a pull-up voltage and a pull-down voltage of each of candidate terminals to be discriminated; a discriminating unit for comparing the pull-up voltages, pull-down voltages, and the differences between the pull-up voltages and pull-down voltages for the candidate terminals to discriminate the types of the candidate terminals; and an output unit for outputting results of the discrimination of the candidate terminals transferred from the discriminating unit. The types of the candidate terminals can be discriminated by comparing the pull-up voltage, the pull-down voltage, and the differences between the pull-up voltages and the pull-down voltages for the candidate terminals.
