Abstract
A sensing system is described herein. The sensing system includes a sampling module configured to define a sampling interval. The sensing system also includes a plurality of sensors to sample an inserted item based at least on the sampling interval. The sensing system includes a tracking module configured to obtain start sensor data from the sensors, determine if start sensor data is absent, increment an absence count based at least on the determination, compare the absence count with a threshold absence count, and reject the inserted item based at least on the comparison.
Claims20
A sensing system comprising:
- a sampling module configured to define a sampling interval;
- a plurality of sensors to sample an inserted item based at least on the sampling interval;
- and
- a tracking module configured to,
- obtain start sensor data from the sensors;
- determine if start sensor data is absent;
- increment an absence count based at least on the determination;
- compare the absence count with a threshold absence count;
- and
- reject the inserted item based at least on the comparison.
A method comprising:
- receiving an item, wherein the item is at least one of a non-banknote item and a banknote;
- obtaining start sensor data from at least one start sensor by sampling the start sensor at predetermined sampling intervals, in response to the received item;
- determining whether start sensor data is absent;
- if the start sensor data is absent, incrementing an absence count;
- comparing the absence count with a threshold absent count;
- and
- rejecting the item as a non-banknote item based at least on the comparison.
A method comprising:
- obtaining one or more samples from a plurality of sensors, in response to an item inserted into an electronic transaction system;
- analyzing a predetermined number of samples to determine whether data is absent in the samples;
- comparing a number of times data is absent with a predetermined value;
- and
- detecting the inserted item based on the comparing.
