The accuracy of global positioning system receivers can be improved by differential correction systems (DGPS), which deliver sub-meter accuracy. Higher-accuracy, of about 1cm on-the-go, is delivered by units generally referred to as real-time kinemat

An improved spectrophotometric pCO2 sensor based on a long pathlength liquid-core waveguide is described for pCO2 underway measurements. A low refractive index (RI) amorphous fluoropolymer (Teflon AF 2400) tubing, the heart of the sensor, served as b

Two sizes of H apple cultivars were placed on a bicone conveyor used in commercial sorting machines and on an experimental conveyor. In less than 18 seconds, apples were oriented into one of two modes, either parallel (desired) or nonparallel (undesi

A technique using body transmittance in the 450- to 1050-nm region was evaluated as a non-destructive technique for identifying apples with internal breakdown. Apples with internal breakdown absorbed shorter wavelengths of light ( 750 nm) was absorbe

An apparatus was designed and built to deliver micronized dust particles to the foliage of mature orchard trees under a mobile canopy. The dust is propelled by compressed air (about 1120 kPa), which is pulsed through sand-blast guns using the Bernoul

Stored ‘Red Delicious’ apples can have old and new bruises. Previous studies have shown the near-infrared (NIR) reflection of bruised tissue with respect to unbruised tissue to be darker in new (24 h) bruises and lighter in old (four to six weeks

Near-infrared imaging was used to characterize the influence of time, bruise-type, and severity on the near-infrared (NIR) reflectance from bruised and unbruised regions on ‘Delicious’ and ‘Golden Delicious’ apples. Images of apples were capt

Watercore damage was quantified in ‘Red Delicious’ apples by measuring light transmitted through the apple along the stem/calyx axis. Two black and white video cameras with different intensity sensitivities were used to capture images of the stem
