  • Patent number: 10068406
    Abstract: Currency processing systems, coin processing machines, and methods of imaging coins are presented herein. A currency processing system is disclosed which includes a housing with a coin input area for receiving coins and coin receptacles for stowing processed coins. A disk-type coin processing unit is coupled to the coin input area and coin receptacles. The disk-type coin processing unit includes a rotatable disk for imparting motion to the coins, and a sorting head having a lower surface adjacent the rotatable disk. The lower surface forms various shaped regions for guiding the coins, under the motion imparted by the rotatable disk, to exit channels through which the coins are discharged to the coin receptacles. A linear array of sensors is mounted to the sorting head and/or the rotatable disk. The sensors examine each coin on the rotatable disk and output a signal indicative of coin image information for processing the coin.

  • Patent number: 7963382
    Abstract: An method for determining the denomination of a coin with a disk-type coin processing system comprises moving a coin along a coin path with a rotatable disk, generating an encoder pulse for each incremental movement of the rotatable disk, directing a light beam transverse the coin path, detecting the light beam with a light detector, developing a signal at the light detector indicating the presence of a coin in the coin path, counting a number of encoder pulses occurring while developing the signal at the light detector, and comparing the counted number of encoder pulses to a plurality of stored numbers of encoder pulses corresponding to the particular coin denominations.

  • Patent number: 7946406
    Abstract: A coin processing system includes a coin processing machine configured to receive a plurality of randomly oriented coins in a coin input region thereof, process the coins, and determine a total amount of the coins. The coin processing system also includes a sensor configured to measure a pre-determined property associated with a component of the coin processing machine and/or an operational state of the coin processing machine and to output to a controller a signal related thereto. The coin processing system also includes an actuating device disposed to influence the pre-determined property. A controller is configured to monitor the signal output by the sensor and, responsive to a deviation of a value of the signal from an acceptable value for the signal, to execute an error recovery instruction set at least once.

  • 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.

  • Patent number: 7256874
    Abstract: A counterfeit determination is made with respect to currency bills by illuminating the currency bill with multiple wavelengths of light. Genuine currency bills include indicia printed with an ink that responds similarly to infra-red illumination at two different wavelengths. To identify a test currency as a suspect counterfeit, the bill is first illuminated with infra-red light at a first wavelength. A measurement is then made of a first reflected light response from the first illumination. The test currency bill is then second illuminated with infra-red light at a second wavelength. A measurement is then made of a second reflected light response from the second illumination. The first and second reflected light responses are then compared, and the test currency bill is identified as a suspect counterfeit if the first and second reflected light responses are not substantially the same.

  • Patent number: 7188720
    Abstract: A coin processing system for processing a plurality of coins of mixed denominations comprises a rotatable disc for imparting motion to the plurality of coins, a sensor for differentiating between valid and invalid coins, a stationary sorting head, a diverter and a controller. The stationary sorting head has a lower surface generally parallel to and spaced slightly away from the rotatable disc. The lower surface forms a queuing channel and a plurality of exit channels for sorting and discharging coins of particular denominations. The queuing channel has a first segment for receiving coins and a second segment for moving the coins past the sensor and is configured to move coins at a faster rate along the second segment for increasing the spacing between adjacent coins. The diverter is disposed along the second segment beyond the sensor and is moveable between a first position for permitting coins to proceed to the plurality of exit channels and a second position for diverting coins to a reject region.
