  • Publication number: 20230085210
    Abstract: A temperature estimation apparatus includes: a first temperature sensor that measures first temperature of first part of a target that has a heat source; a second temperature sensor that measures second temperature of second part that is farther from the heat source than the first part; and a processor. The processor obtains temperature-for-estimation data regarding the first and second temperatures that are measured in a state where a predetermined condition is satisfied, the predetermined condition corresponding to a certain state of change in the temperature of the heat source. Based on the obtained temperature-for-estimation data, the processor obtains a single thermal resistance parameter in a thermal model. Based on the obtained thermal resistance parameter and the measured first and second temperatures, the processor estimates the temperature of the heat source as a deep-body temperature of the target.

  • Patent number: 10540972
    Abstract: A feature extractor extracts feature quantities from a digitized speech signal and outputs the feature quantities to a likelihood calculator. A distance determiner determines the distance between a user providing speech and a speech input unit. The likelihood calculator selects registered expressions for speech recognition from a recognition target table based on the determined distance, to be used in calculation of likelihoods at the likelihood calculator. The likelihood calculator calculates likelihoods for the selected registered expressions based on the feature quantities extracted by the feature extractor, and outputs one of the registered expressions having the maximum likelihood as a result of speech recognition.
