Abstract: A method of automated defect detection of a dental appliance comprises receiving a plurality of images of the dental appliance, and processing the plurality of images by a processing device to determine one or more defect estimations. The method comprises processing one or more sets of defect estimations to determine one or more defect classifications, wherein each set of the one or more sets comprises the one or more defect estimations associated with a subset of the plurality of images. The method comprises determining whether the dental appliance has a defect based on the one or more defect classifications associated with the one or more sets of defect estimations.

Abstract: A frameless photovoltaic module constructed as a laminated sandwich comprising an optically transparent plastic film glazing layer, an optically transparent upper adhesive layer, a matrix of PV cells, a middle layer adhering said PV cells to a PV cells back lining layer consisting of a matrix of an individual plastic film tiles having the same quantity, footprints and arrangement as the PV cells and another sides of said plastic film tiles are adhered to a PV module rigid base sheet, said plastic film glazing layer, being adhered to said PV cells and to said rigid base sheet, in spaces between said PV cells and the rigid base sheet peripheral areas, forms in-folds in the grooved spaces between said PV cells, where said in-folds allow compensation for thermal expansion and contraction of said plastic film glazing. Interspaces between adjacent PV cells chamfered corners are arranged with mounting holes reinforced by eyelets.

Abstract: A folding boat with at least two foldable horizontal frames each comprising at least two foldably connected sections a frame. Said sections comprise two longitudinal rails connected by a plurality of transverse members and at least one swivelly foldable guard rail with releasable locking means. Said longitudinal rails comprise internal and external longitudinal groves, where said internal longitudinal grooves hold a plurality of removable and stackable floats. Said floats can be equipped with at least two fins attached to the bottom of said floats for attachment of boat launching wheels. One of said horizontal transverse has two front guard rails equipped with a guiding channels supporting a slideable frame of climbing step, where said frame is slideably movable between an upper retracted position acting as a guide rail and said frame being moved to lower position provides convenient position of the climbing step.

Abstract: A draw latch with a safely catch for fastening two members, where the latch comprises a base attached to one of the two members, a lever pivotally connected to the base for movement between closed and open positions, a draw bar pivotally connected at one end with the lever providing toggle action upon the latch lever closing and another end of the draw bar is for engagement with a draw plate attached to the other of the two members. The safety catch comprises a safety catch bolt with thumb knob, with the colt biased into a locked position by a compression spring to prevent the latch from opening. The safety catch can be placed into an open position by pushing the knob, so the safety catch bolt will disengage from a sidewall of the lever, allowing the lever to be lifted to open the latch.

Abstract: A draw latch 13 with a safety catch for fastening two members 11 and 12, where said latch comprises a base 16 attached to said member 12, a lever 17 pivotally connected to said base 16 for movement between closed and open positions, a draw bar 15 pivotally connected with one end to said lever 17 providing toggle action upon the latch lever 17 closing and another end of said draw bar 15 is for engagement with a draw plate 14 attached to said member 11. Said safety catch comprises a safety catch bolt 22 with thumb knob 21, where said bolt 21 is supported by a side wall of said lever 17 a support bracket 25 attached to said lever 17, said safety catch bolt 22 orientation is substantially parallel to the pivotal axis of said latch lever 17.

Abstract: A folding boat (11) with at least two foldable horizontal frames (12) each comprising at least two fold ably connected sections secured to each other by releasable locking means (24) and equipped with at least one foldable guard rail (26). Said frames (12) are connected by a plurality of removable horizontal transverse beams (34) supporting deck sheets (44) and are secured to the frames (12) by releasable locking means (38), said frames (12) hold a plurality of removable and stackable floats and said deck sheets (44). Said floats can be three types of configurations: for individual installation, paired mirror oriented installation or combination of the intermediate and the end floats forming a continuous hull. Said floats are equipped with removable and stackable gasketted watertight covers (48) and with a removable stiffening elements (80) installed inside.

Abstract: A folding boat (11) with at least two foldable horizontal frames (12) each comprising at least two fold ably connected sections (12A), (12B) in one said frame (12) and (12C), (12D) in another said frame (12). Said sections are attached to each other by a transverse swivel joint (22) on one side and by releasable locking means (24) on another side. Said sections comprise two longitudinal rails (14) connected by a plurality of transverse members (16) and at least one swivelly foldable guard rail (26) with releasable locking means (32). Said longitudinal rails comprise internal (20) and external (18) longitudinal groves, where said internal longitudinal grooves hold a plurality of removable and stackable floats (46) with gasketted covers (48).

Abstract: An aircraft has a geometrically transformable pilot compartment, and further parts including a fuselage boom, wings and tail, wherein at least one of these parts are movable between an unfolded position in which it is ready for flying and a folded position in which it is accommodated in the pilot compartment.
