With a total of four patents to his name, Fraser has developed sophisticated apparatuses that enhance the efficiency and reliability of coin handling systems.

Latest Patents

Among his latest innovations is a coin identification apparatus that employs a pair of series-connected coils driven by an oscillator. This apparatus detects the frequency and amplitude characteristics of a coin as it passes between the coils, comparing these with pre-stored characteristics of acceptable tokens. Upon identifying a match, a processor activates a motor to rotate a coin receptacle, allowing the token to be returned to the user. This innovative design also facilitates the opening of the enclosure door, permitting access to the interior, and modifies the total vend value associated with the detected token.

Fraser has also developed another iteration of a similar coin identification apparatus, featuring spaced series-connected elongated planar coils driven by an oscillator. This device compares maximum frequency and amplitude values generated during the passage of a coin with preset acceptable values. When a match occurs, it activates a motor to dispense coins into a storage receptacle and simultaneously releases a latch mechanism that allows for vending access.
