Abstract
Abstract A produce recognition system and method which use an internal reference to calibrate a produce data collector. The produce data collector collects first data from an external reference, collects second and third data from an internal reference, and collects fourth data from a produce item. A computer determines a first calibration value from the first and second data and a second calibration value from the third data and applies the first and second calibration values to the fourth data to produce fifth data. The computer further obtains sixth data from reference produce data and compares the fifth and sixth data to identify the produce item.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
102 words
A produce recognition system comprising: a produce data collector for collecting first data from an external reference and second and third data from an internal reference, and for collecting fourth data from a produce item; and a computer coupled to the produce data collector which determines a first calibration value from the first and second data and a second calibration value from the third data, which applies the first and second calibration values to the fourth data to produce fifth data, which obtains sixth data from reference produce data, and which compares the fifth and sixth data to identify the produce item.
Claim 2
Dependent Claim
102 words
A produce recognition system comprising: a produce data collector for collecting first data from an external reference and second and third data from an internal reference, and for collecting fourth data from a produce item; and a computer coupled to the produce data collector which determines a first calibration value from the first and second data and a second calibration value from the third data, which applies the first and second calibration values to the fourth data to produce fifth data, which obtains sixth data from reference produce data, and which compares the fifth and sixth data to identify the produce item.
Claim 3
Dependent Claim
88 words
The produce recognition system as recited in claim 1 , wherein the produce data collector comprises: a housing containing a window; a light source within the housing having a light path oriented through the window for illuminating the external reference and the produce item; a collector within the housing for collecting reflected light from the external reference, the internal reference, and the produce item; and a shutter assembly inside the housing for positioning the internal reference in the light path during collection of the second and third data.
Claim 4
Dependent Claim
53 words
The produce recognition system as recited in claim 2 , wherein the collector is located in the housing at an opposite end of a reflected light path from the window, and wherein the shutter assembly also positions the internal reference in the reflected light path during collection of the second and third data.
Claim 5
Dependent Claim
30 words
The produce recognition system as recited in claim 1 , wherein the produce data collector comprises: a memory for storing at least one of the first and second calibration values.
Claim 6
Dependent Claim
17 words
The produce recognition system as recited in claim 1 , wherein the computer comprises a transaction terminal.
Claim 7
Dependent Claim

Claim 10
Dependent Claim
26 words
The produce data collector as recited in claim 7 , further comprising: a memory for storing at least one of the first and second calibration values.
Claim 11
Dependent Claim
99 words
A produce recognition system comprising: collecting means for collecting first data from an external reference and second and third data from an internal reference, and for collecting fourth data from a produce item; and processing means coupled to the collecting means for determining a first calibration value from the first and second data and a second calibration value from the third data, for applying the first and second calibration values to the fourth data to produce fifth data, for obtaining sixth data from reference produce data, and for comparing the fifth and sixth data to identify the produce item.
Claim 12
Dependent Claim
99 words
A produce recognition system comprising: collecting means for collecting first data from an external reference and second and third data from an internal reference, and for collecting fourth data from a produce item; and processing means coupled to the collecting means for determining a first calibration value from the first and second data and a second calibration value from the third data, for applying the first and second calibration values to the fourth data to produce fifth data, for obtaining sixth data from reference produce data, and for comparing the fifth and sixth data to identify the produce item.
Claim 13
Dependent Claim
