  • Patent number: 7552810
    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.

    Abstract: A self-checkout terminal is provided which includes a coin recycling machine which stores a coin inserted into a coin inlet in accordance with a denomination of the coin and releases the sorted coin through a coin outlet. A coin receiver receives a coin released through the coin outlet. A coin path couples a coin slot and the coin inlet, and a fake coin path diverges from the coin path toward the coin receiver. A judging unit judges whether a coin inserted into the coin slot is real or fake, and a sorting unit sorts a coin judged to be fake into the fake coin path. When a coin inserted into the coin slot is judged to be fake and is sorted into the fake coin path, information that there is something wrong with the coin is provided to a customer. A coin as change is released through the coin outlet.

  • Patent number: 7213697
    Abstract: A coin discrimination apparatus and method is provided. Coins, preferably after cleaning, e.g. using a trommel, are singulated by a coin pickup assembly configured to reduce jamming. A coin rail assists in providing separation between coins as they travel past a sensor. The sensor provides an oscillating electromagnetic field generated on a single sensing core. The oscillating electromagnetic field is composed of one or more frequency components. The electromagnetic field interacts with a coin, and these interactions are monitored and used to classify the coin according to its physical properties. All frequency components of the magnetic field are phase-locked to a common reference frequency. The phase relationships between the various frequencies are fixed, and the interaction of each frequency component with the coin can be accurately determined without the need for complicated electrical filters.

  • 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: 7108120
    Abstract: A coin inspection method and apparatus capable of inspecting coins having different materials and surface patterns with high accuracy by a simple coil arrangement. An exciting coil is arranged in the vicinity of one side of a coin passage inclined at a predetermined angle so that two magnetic poles thereof face the coin passage. Two receiving coils having substantially identical characteristics are arranged in the vicinity of the same side of the coin passage so that the receiving coils are electromagnetically coupled with the exciting coil. The exciting coil is excited at a predetermined frequency and an oscillation voltage of the exciting coil is detected. Also, an influence of a reactive magnetic field produced by eddy current induced on a surface of the coin is detected by the receiving coil. Material of the coin can be determined based on the oscillation voltage level of the exciting coil.

  • Patent number: 6988606
    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.

  • Patent number: 6907977
    Abstract: A capacitance sensor measures a coin to determine geometrical parameters thereof and to allow assessment of different geometrical parameters of a coin which influence the measured capacitance. In a preferred arrangement, a mechanical arrangement alters the capacitance between two electrodes as a function of the diameter of the coin. This assessment is used in combination with a further measured capacitance which is a function of coin diameter, coin thickness and surface relief of the coin. The initial evaluation of diameter is useful in determining the separate influences of coin thickness and surface relief. The invention is also directed to the method of coin evaluation.
