Abstract: Presented is a wireless portable ultrasound acquisition system for dental imaging, having an ultrasound probe with a control switch connected through a cable to a portable ultrasound acquisition system that communicates wirelessly with a smart tablet or a phone display to display the ultrasound images. The system uses ultrasound signals to create images of alveolar bone structure and boundaries of enamel, dentin and gingiva of a patient.

Abstract: A harvesting head utilized with or incorporated into a mechanical harvesting machine for harvesting crops. The harvesting head has a frame that attaches to a frame member of the harvesting machine. The frame defines a harvesting area sized to receive the canopy of a tree or vine and supports a picking assembly and a motion inducing mechanism. The picking assembly comprises a pair of sub-structures having a forward post member, rearward post member, a connecting member connecting the two posts and a plurality of curvilinear rods, which also interconnect the posts, that extend into the harvesting area. The motion inducing mechanism is connected to and pivots the posts of the picking assembly so as to rapidly move the rods forward and backward to engage the canopy and dislodge the crop therefrom. A conveying assembly conveys the crop to a bin.

Abstract: A process is provided for isolating vanillin from alkaline aqueous solutions containing unwanted, chemically-related phenolic impurities, such as orthovanillin, acetovanillone, para-hydroxybenzaldehyde, syringaldehyde and the like, wherein the alkaline aqueous solution is subjected to an extractive process including as a step, extractive bisulfitation. The step of extractive bisulfitation involves the formation of an alkali-metal bisulfite complex of vanillin in the presence of a substantially water-insoluble organic solvent, such as a water-insoluble alkanol, e.g., normal-butyl alcohol.
