Abstract: An oxidation-reduction substance equilibrium potential estimating method is provided, the method including: applying a voltage to an electrode contacting a sample containing an oxidation-reduction substance and sweeping the voltage; measuring a current flowing through the electrode; if an integrated value of the current becomes a value within a reference range, determining whether to sweep the voltage in an opposite direction to a sweep direction in the previous sweeping or to terminate sweeping of the voltage; if it is determined to terminate sweeping of the voltage, estimating an oxidation-reduction substance equilibrium potential at a value of the voltage; and if it is determined to sweep the voltage, sweeping the voltage in an opposite direction to a sweep direction in the previous sweeping.

Abstract: Provided are an information recognition device, an information recognition method, and an information recognition program capable of recognizing predetermined information associated with an object-to-be-detected according to output of thermal radiation detection means for an object-to-be-detected existing in a detection range and a behavior pattern model corresponding to the output of the thermal radiation sensor corresponding to behavior patterns of objects prepared in advance by using a predetermined modeling method. The information recognition device 1 includes an infrared detection unit 10, a behavior pattern model generation unit 11, a behavior pattern model storage unit 12, and a recognition unit 13. The infrared detection unit 10 has a pyroelectric infrared sensor 10a and a signal processor 10b. The behavior pattern model generated is correlated to the behavior content and the attribute information and stored in the behavior pattern model storage unit 12.

Abstract: A forward equalizer subjects a received signal to equalization in a forward direction with respect to time base, and outputs a signal representative of the equalization result. A backward equalizer subjects the received signal to equalization in a backward direction with respect to time base, and outputs a signal representative of the equalization result. An equalizer-less detector subjects the received signal to detection, and outputs a signal representative of the detection result. A determination is made as to whether or not both the signals outputted from the forward equalizer and the backward equalizer reside in a selection reference range. When both the signals outputted from the forward equalizer and the backward equalizer do not reside in the selection reference range, a final decision-result symbol is determined on the basis of the signals outputted from the forward equalizer, the backward equalizer, and the equalizer-less detector.
