  • Patent number: 9235947
    Abstract: A subject discriminating apparatus discriminates a subject having an unevenness pattern on a surface of the subject. The subject discriminating apparatus includes: a transparent unit including a supporting surface supporting the subject; a light irradiation unit irradiating illumination light onto the surface of the subject through the transparent unit; an imaging unit imaging an imaging region including at least a part of the transparent unit, and generating image data; and a discrimination processing unit discriminating the subject, using the image data generated by the imaging unit. The discrimination processing unit discriminates the subject based on discrimination image data generated by correcting subject image data using correction image data. The subject image data is generated by imaging the imaging region in a state of the subject presenting in the imaging region. The correction image data is generated by imaging the imaging region free from the subject in the imaging region.

  • Publication number: 20110186402
    Abstract: A reference data set used for classifying items of currency is established by obtaining at least one measured response from at least one known item of currency, projecting the measured response data from the known item of currency from a first space to a second space, and applying a reduction technique to the second space thereby reducing the complexity of the second space. The reference data set, which can be used for classifying items of currency, is thus represented by a subset of all measured responses obtained from the known item of currency.

  • Patent number: 7584833
    Abstract: A coin discriminator measures both the surface and average electrical conductivity of coins in order to distinguish genuine minted coins from fake or bogus coins such as cast coins which may be nominally of the same material as a minted coin. The conductivities are measured using a coil to induce eddy currents within the coin. The high frequency components of the eddy current are monitored to measure the surface conductivity. The low frequency components are measured to monitor the bulk or average conductivity.

  • Publication number: 20090166150
    Abstract: In a discrimination apparatus of the invention, a banknote or another paper as an object of discrimination is irradiated with ultraviolet radiation from an array of multiple ultraviolet-emitting LEDs. The ultraviolet radiation passes through a visible radiation block filter and is focused onto a preset site of the banknote by a lens. Multiple photodiodes are used to measure the transmitted light of ultraviolet radiation and the fluorescence, which is excited by the ultraviolet radiation from the banknote. The discrimination apparatus of the invention discriminates counterfeit banknotes from genuine banknotes, based on the observed pattern of the transmitted light over a preset range of the banknote. The technique of the invention desirably enhances the accuracy of discrimination in the discrimination apparatus that discriminates counterfeit banknotes from genuine banknotes.

  • Patent number: 7152727
    Abstract: A coin sensor is provided including a method and apparatus for providing adaptive operating point (AOP) control. The AOP control is provided using circuits and associated methods and algorithms connected between measurement circuits of the coin sensor and the coin sensor oscillator. The AOP control automatically monitors and controls the quiescent voltage levels of four signals used by the coin sensor to discriminate coins. The four signals represent coin size and coin composition. In addition, the AOP control automatically performs calibration and adjustment functions both during manufacture of the coin sensor system and during its operational life. The automatic monitoring and control functions provided by the AOP control result in a significant increase in the dynamic range of the coin sensor response. This reduces the coin false-reject rate while improving the coin discrimination precision.

  • Patent number: 7104384
    Abstract: A method for measuring the diameter of coins in coin validators, comprising the steps below: The coins traverse an electromagnetic field which is formed such as to partially hide the field, at least also by their upper area. The field is generated between at least one transmitter coil and a receiver coil. The transmitter coil is periodically acted on by a short transmission pulse the duration of which is small as compared to the time of coin passage. The maximal attenuation values are determined for different times of the transmission pulse. The attenuation values measured are extrapolated into time 0. The measured value determined by extrapolation is compared to a predetermined acceptance band or a predetermined characteristic line for coin diameters for comparison to a stored setting.

  • Patent number: 6892871
    Abstract: A coin discrimination sensor having an excitation coil and two detector coils arranged to detect eddy currents in a passing coin. The excitation coil is provided a composite waveform formed by adding a low frequency signal (30 KHz) with a high frequency signal (480 KHz). The two detector coils are arranged at different distances from the passing coin, and are calibrated to eliminate the common-mode voltage when no coin is present. As a coin passes by the sensor, eddy currents are induced in the coin which result in phase and amplitude shifts in the low and high frequency components of the detector signal. The low and high frequency components are separated from the detector signal, and their respective phases and amplitudes are ascertained and compared against values stored in a lookup table. These values represent the composition, thickness, and diameter characteristics of known coins, and if the signature of the processed coin does not appear in the lookup table, it can be flagged as an invalid coin.
