Latest Patents

Watanabe's latest patents include a predicting apparatus, predicting method, and computer product. This invention features a structuring unit that generates a combination pattern of attribute values by integrating an attribute value of the assessment target data with an attribute value indicating an unspecified value. Additionally, a reconstructing unit searches for data that matches the combination pattern from accumulated data, generating subset data. An index setting unit establishes an index that indicates the significance of the relationship between the generated subset data and assessment data. Finally, an assessing unit selects subset data that serves as the basis for assessment, performing an evaluation on a prediction result based on the selected subset data.

Another significant patent is an optical fiber attenuator with an attenuating dopant limited to a central or peripheral area of the fiber core. This optical attenuator provides nearly the same degree of attenuation, even when the difference in wavelength between two different kinds of input optical signals is minimal. The design includes a dopant concentration within a technically realizable range, which enhances the difference in optical attenuation of the two input signals. By adjusting the refractive index of the axially central portion of the core compared to that of the peripheral portion, the invention effectively cancels the wavelength dependency of attenuation.
