Abstract: A construction thermoacoustic partition to isolate areas from external or internal environments, refrigeration, and vehicles. The partition consists of a frame with airtightly glued insulating panels, transparent or not. If glass pane, frame, and panels are glued, they create an airtight chamber where pressure, light and solar tracking sensors are located. In its internal perimeter it has photovoltaic cells and a blind whose sheets are photovoltaic cells that make it self-sufficient in energy. The profile of the frame has channels to circulate air, where electric resistance is located, which in winter raises the temperature of the panel edges, in another, fans, temperature sensors, micro-pump, wires and reinforcements are located. The horizontal planes that create these channels have coextruded thermoacoustic bridges.

Abstract: The invention is a solution for osteosynthesis made with molded metal sheets joined vertically and horizontally, fitted to the shape and dimensions of the fractured bone to keep it immobile and united. For the orthosis, it depicts metal sheets joined with horizontal and vertical movements, molded to the form and dimensions of vertebrae and joints to keep them separated. The sheet metals have wavy shapes, channels and undulations that give consistency and structural strength to bending, tension, shear and bends for joints. It also describes the process for the osteosynthesis with metal sheets and 3D printing, where the surgeon wraps the osteosynthesis or molded orthosis around the bone, vertebrae or joint, fastening it with clamps that tighten and lock with a surgical instrument, without screws. The sheet metals have viewpoint holes to see through during surgery and subsequent control with Roentgen. The clamps are in channels, which have micro-points on the side contacting the bone.

Abstract: Helical body with blades for cutting, stirring, removing and cleaning in solids and closed and open tubular shapes. The blades create more points to cut and contact with less material and remove what they cut and withdraw in the same movement. In ear cleaning they reduce the risk of pushing in the cerumen. The helicoid to remove earwax is manufactured with the same processes and machines of the art of swabs, adding two steps, preforming and forming. This one, by placing halves of helicoid molds in bands or cylinders where, by pressure, a vacuum, and heat, they form the blades. The machine produces quantities per minute similar to the current ones. Uses of the invention are possible in cutting and removal of rocks, in mechanical tools for working on metals or hard materials, in medicine for removal and extraction in ducts, veins and arteries, in personal use and domestic utensils where blades replace fibers.

Abstract: An in-ear stimulation system including a first device configured to be worn at least partially in a first ear canal of a subject and a second device configured to be worn at least partially in a second ear canal of the subject. Each of the first device and the second device includes: at least one in-ear active electrode configured to receive a bio-signal and at least one in-ear reference electrode configured to receive a bio-signal; at least one stimulation device configured for emitting at least one electrical or sensory stimulus; and an electronic system configured to detect at least one bio-signal pattern from the bio-signals measured from the electrodes.

Abstract: A container and its airtight closure. By crimping an open container a new rim (050) is made having two salient outer (05B) and inner (05A) sides and planes (05A, 05B) where a gasket (24) can be accommodated. A typical airtight closure for the open container is made up of a protecting cover (2) joined to an outer rim (5) that accommodates with precision to the brim of the can (05). It has also an internal rim (4) which along with the outer rim (5) forms a slot (070) on the protecting lid, which has an inner (5A) and outer (5B) sides which conform to the inner and outer sides (05A) and (05B) of the sealed brim. The closing surface (2) has an inverted arch-like (25) shape, which by mechanical action and gas pressure of the content, renders an airtight seal on the contact planes (2B, 05B).

Abstract: An assembly system used to build two pane thermoacoustic windows for houses and buildings is provided. The assembly system uses a set of profiles and joints and a permanently installed valve to assemble the window frame without a fusion welding machine. The system creates an airtight chamber directly on the frame. The valve allows the assembler to evacuate the air in the airtight chamber to make a vacuum, or to inflow a gas. The system improves the insulating thermal and acoustic capacity of the window, and allows a supplier to sell the components to build the window, which is then assembled by snapping together profiles and joints. The system can also be applied to assembly one pane window and for other purposes.
