Abstract
An acceptor for evaluating banknotes, or other paper forms of payment, that includes a replaceable sensor module which communicates in a standardized manner with a central processing unit. The sensor module includes a series of sensors and the signals of the sensors under go primary processing by the sensor module to correct for at least individual characteristics of the sensor module. The central processing unit can be updated if required for different applications. This arrangement adds considerable flexibility in maintenance of the acceptor as well as changing the application of the acceptor.
Claims18
In a banknote validator a sensing module for evaluating a banknote during movement past said sensing module;
- said sensing module comprising a casing housing a series of sensors for evaluating different properties of banknotes, a signal processing and quantization unit which includes individual parameters for each sensor, said signal processing and quantization unit receiving the signals of said series of sensors and converting said signals into corrected signals using said individual parameters, said signal processing and quanitzation unit outputting said corrected signal through an electrical interface connection exterior to said casing for connecting said sensing module with a central processing unit of the validator.
A banknote validator comprising a banknote inlet for receiving a banknote, a transport arrangement for transporting banknotes along a pathway for processing, at least one removable sensor module located in a wall of said pathway for sensing properties of banknotes as the banknotes are transported along said pathway past said at least one removable sensor module, a central processing unit separated from said at least one removable sensor module and in electrical communication with said at least one removable sensor module to receive corrected digital signals of said sensor module and process and compare said signals to a standard for determining the authenticity of a sensed banknote, said at least one removable sensor module comprising a casing housing a series of sensors for evaluating different properties of banknotes, a signal processing and quantization unit which receives the signals of said series of sensors and converts said signals to compensate for individual characteristics of said series of sensors to produce said corrected digital signals and provide said corrected digital signals to said central processing unit, and an electrical interface connection exterior to said casing connecting said sensing module with said central processing unit.
A banknote validator for assessing the authenticity of banknotes as each banknote is moved past a sensing arrangement comprising a banknote inlet for receiving a banknote, a transport arrangement for transporting banknotes along a pathway for processing, at least one removable sensor module located in a wall of said pathway for sensing properties of banknotes as the banknotes are transported along said pathway past said at least one removable sensor module, a central processing unit separated from said at least one removable sensor module and in electrical communication with said at least one removable sensor module to receive signals of each sensor module and process and compare said signals to standards for determining the authenticity of a sensed banknote, said at least one removable sensor module producing at least one signal reflective of the characteristics of each banknote as it moves past said sensor module and corrects said signal for individual characteristics of said sensor module to produce a standardized sensed signal of said banknote, said sensor module providing said standardized sensed signal of said banknote to said central processing unit for further processing.
