Abstract: The present document describes a method for extracting anthocyanin derivatives from a plant source. The method comprises the step of separating a homogenized extract of plant source in a polar acidified solvent for obtaining a residual solid, and a filtrate mixed with the acidified polar solvent. The separation includes a coarse filtration done by centrifugation of the plant source extract, by a filtration with a first filter having a pore size of about 100 ?m, and a fine filtration is done using a second filter having a pore size of about 10 ?m. Then, the filtrate mixed with the acidified polar solvent is evaporated for substantially separating the acidified polar solvent from the filtrate to obtain a semi-solid extract of anthocyanin derivatives.

Abstract: The present invention relates to a snowplow arranged to be towed behind a vehicle. The towed snowplow comprises: a frame removably securable to the vehicle; at least one moldboard mounted to said frame and extending under said frame; and at least one pivotable side wing plow mounted to one side of the frame and configurable between a non-operative configuration and a snow plowing configuration in which the at least one pivotable side wing plow extends laterally from the side of the frame. It also relates to a method for plowing snow using a towed snowplow.

Abstract: The present invention generally pertains to a mechanical sweeper. The mechanical sweeper comprises a pickup broom for lifting debris toward a first belt conveyor. The sweeper further comprises a second deployable conveyor assembly mounted on a turntable and adapted for conveying the debris from the first conveyor to an auxiliary vehicle such as a dump truck.

Abstract: A system for three-dimensional scanning, comprising a three-dimensional scanning apparatus being manually maneuverable and comprising a profilometer including a light beam projector, an objective and a light detector. The profilometer is configured for obtaining a two-dimensional profile of an object by active triangulation. The apparatus further including a positioning device being trackable in a volume space for providing six degrees-of-freedom of the apparatus, whereby a three-dimensional profile is calculatable by relating the two-dimensional profile with time-corresponding positions and orientations of the apparatus. The system also has a three-dimensional profile calculator remote from the apparatus, for tracking the apparatus in the volume space and relating positions and orientations of the apparatus with a time-corresponding two-dimensional profile of the object for calculating a three-dimensional profile of the object and for referring the object to a static position and orientation.
