Configuration is made by a feature pattern extracting section 12 for extracting a feature obtainable from a person, a subspace calculating section 14 for calculating a subspace from the feature pattern, a recognition section 16 for effecting recognition using the subspace, a registered information holding section 18 for holding a plurality of the subspaces, and a registered information updating section 20 for updating the registered information using the subspaces. When identifying a person, the effect of aging change is reduced by suppressing time and year changes and keeping the recognition rate high.

A multi-band radio, comprising: a radio receiver for operating on a first and a second radio frequency band in which said second radio frequency band is substantially less than the third harmonic of said first radio frequency band; a first section attached to an antenna connection base attached to the radio receiver; a second section adjacent to and distal from the first section; a helical coil electrically connected to said antenna connection base and extending through both the first and second sections, and having a uniform winding pitch and diameter throughout; a first core of a first dielectric material at least disposed in the first section and that imposes a first distributed inductance and capacitance effect on a near-end part of the helical coil; a second core of a second dielectric material having a different dielectric constant than that of said first dielectric material, and disposed only in the second section, and abutting the first core, and further that imposes a second distributed inductance and capacitance effect on a distal-end part of the helical coil; wherein, the helical coil has a first resonance at 0.25 wavelengths of a first frequency in said first radio frequency band, and a second resonance at 0.75 wavelengths of a different and higher second frequency that is substantially lower than the third harmonic of the first frequency and in said second radio frequency band. , 1996-730409, 5956011 Commun 1999 Mar;23(2):101-13 (ISSN: 0165-7380) Rainsford KD; Skerry TM; Chindemi P; Delaney K Division of Biomedical Sciences, School of Science and Mathematics, Sheffield Hallam University, Sheffield, UK.
