A total of 370 tomatoes from two seasons were analyzed using a vision system and three mechanical properties sensors which measured firmness parameters. Multiple linear regression indicated classification based on color and firmness could be applied in practical sorting and improves overall classification. Hue values provided adequate information for classification. The best model (R 2 ϭ 0.96) based on 13 specific colors yielded severe misclassification of 2.2% for classification into 12 maturity classes and 79% correct classification with all samples classified ‫ע‬ one maturity stage according to USDA standards. A weighted color parameter provided a stable model invariant to changes in lighting conditions and yielded excellent results (R 2 ϭ 0.89). Quality classification was successfully achieved using a vision and drop impact sensor.

Introduction Interpregnancy interval (IPI) is defined as the period between a live birth and the conception of a subsequent fetus. Both short (IPI < 6 months) and long IPI (IPI > 60 months) have been shown to increase the risk for adverse perinatal outcomes, some of which, are known risk factors for obstructive sleep apnea syndrome (OSAS) in the offspring. Aims To study the association between IPI and risk for offspring OSAS, during a follow‐up period of up to 18 years. Study design Population‐based cohort. Subjects In this population‐based cohort analysis, all singleton live births, born to a mother with at least one previous birth occurring between 1991 and 2014, were included. Congenital malformations were excluded. Materials and Methods Hospitalizations of the offspring due to OSAS diagnosis up to 18 years of age, were evaluated according to IPI length. Intermediate IPI (6–60 months) was considered as the reference. A Kaplan‐Meier survival curve and a Cox hazards regression model were used to compare the incidence of OSAS between the groups, and to adjust for confounding variables. Results The study population included 144,397 deliveries, of which 13.1% (n = 18,947) were followed by short IPI, 7.9% (n = 11,438) and 79.0% (n = 114,012) were followed by long and intermediate IPI, respectively. OSAS hospitalization rates were significantly higher among the long IPI group compared to intermediate and short IPIs (0.9%; 0.7% and 0.6%, respectively, p = .001). The association between long IPI and offspring pediatric OSAS remained significant after controlling for preterm delivery, maternal diabetes, and smoking, and mode of delivery, (adjusted HR = 1.45; 95% CI, 1.17–1.80). Conclusions Children born following long IPI are at increased risk for pediatric OSAS.
