摘要:
A method is disclosed for determining a branching point within a hollow organ in image data representing the spatial structure thereof. In at least one embodiment, the method includes setting a start point within the hollow organ; determining at least one local threshold which corresponds to the presence of a wall of the hollow organ; carrying out a region growing method using the threshold; analyzing the connectivity of a number of outer growth layers; and localizing a branching on the basis of the connectivity analysis. Moreover, at least one embodiment of the invention relates to a correspondingly designed branching determination unit.

A heat insulated entrance includes a door/window having a frame comprising an elongated, tubular, metal member having an inside wall and a wall transverse thereto with a rib formed adjacent a corner at the intersection of the walls. An elongated metal cladding member having a generally channel shaped transverse cross section with a web forming an inside wall face of the door/window and a pair of edge flanges transverse thereto is secured in place on the tubular metal member by a spacer formed of heat insulating material and having one edge in supported engagement with the rib of the tubular frame member. The cladding member has an opposite edge in keyed interengaging relation with an opposite edge of the spacer to complete an insulated frame member assembly having a thermally insulating spacer element between a pair of inside and outside metal portions. The door/window is useful in combination with a heat insulating wall frame system providing a jamb surface, header and sill forming an opening in which the door/window is mounted. The invention also encompasses the conversion of existing, non-insulating type doors/windows into more efficient, heat insulating type, closure members by the addition of insulating spacers and inside metal cladding members in accordance with the invention.
摘要:
A profile assembly includes two profile elements, a profile connecter element, and at least one fastening element connecting the two profile elements to each other using the profile connecter element. The first profile element includes guide channels for receiving two leg parts of the profile connecter element. The first profile element includes at least one fastening channel for receiving the fastening element. The second profile element includes a U-shaped recess for receiving the profile connecter element. In the base, the profile connecter element and second profile element in the bottom of the U-shaped recess thereof respectively include at least one mounting opening corresponding to the fastening channel for passing the fastening element there-through. At least the second profile element is formed in several parts and includes two shell parts in the direction of interior and exterior rooms. The profile shell parts are connected to each other, yet thermally insulated.

摘要:
A thermal break system, comprising an inside steel panel having an inner surface and an outer surface, and a C-shaped section extending about a periphery thereof with a portion of the C-shaped section extending in part parallel to the inner surface of the inside steel panel; an outside steel panel having an inner surface and an outer surface, and a C-shaped section extending about a periphery thereof with a portion of the C-shaped section extending in part parallel to the inner surface of the outside steel panel; and an insulating material interposed between respective C-shaped sections of the inside steel panel and the outside steel panel to thermally isolate the inside steel panel and the outside steel panel from each other, and said inside steel panel and outside steel panel being secured together at respective C-shaped sections to form the thermal break system.
摘要:
The window frame is adapted to receive at least one sash and has metal portions on an outdoor face thermally insulated from metal portions on an indoor face to thereby provide a thermal break. At least in part, the thermal break is attained by way of a thermal barrier strip having spaced parallel zones of contact with juxtaposed walls of the metal portions.
摘要:
A fire shelter including: a foundation including a slab; an internal frame mounted on the slab; external cladding formed from heat resistant masonry panels supported by the internal frame, the external cladding including wall cladding including wall panels and defining a door opening and roof cladding including roof panels; and a door mounted in the door opening, the door including a door frame hingedly connected to the internal frame adjacent to the door opening and door cladding including door panels formed from heat resistant masonry panels supported by the door frame, wherein when the door is in a closed position, the door cladding closes the door opening.
摘要:
A sound insulating window structure having at least two coextensive frames assembled together with an insulating spacer between them, a flexible insulating gasket surrounding each frame and reposing in recesses in the frame and the window opening. Acoustic material lines inwardly facing recesses between the glazing.
摘要:
A window frame system for fixing at least a first panel, includes at least a first window frame structure which includes at least a first window frame profile having at least first and second holders, and at least a first thermally insulating element with sixth and seventh holders. The second holder and the sixth and/or the seventh holder of the first thermally insulating element include at least one internal corner with a radius smaller than 0.5 mm. In this way, the dimensions of the window frame profile may be smaller than in the known window frame profiles. This may be advantageous for the total insulation value of the window frame system and the quantity of material required/used for the window frame profiles. Also disclosed is a thermally insulating element, a method, a window frame structure, a flexible profile, a control system and a sun protection system.
