摘要:
The invention relates to a flexible endoscope device comprising an elongated flexible body having an end segment bearing or defining the endoscope head, and provided with an optical system and that can be curved or bent in at least two mutually perpendicular directions, said elongated body being functionally connected at the other end thereof to a control means capable of controlling at least the movements and/or the arrangement of said end segment. The device (1) is characterised in that it further comprises automatic flexion and positioning means of the end segment (3) by visual control, said means essentially comprising a video processing means (6) for receiving the images or video signals provided by the optical system (4) of the endoscope head (3') using a computer means (7) capable of carrying out visual control operations on the basis of the processed video signals and of transmitting control signals, and actuation means (8, 8') that are part of or associated with the control means (6) capable of controlling the end segment (3) and receiving the control signals supplied by the computer means (7).
摘要:
The present invention relates to a flexible sealing membrane that is particularly useful for covering roofs. The flexible sealing membrane is usable for sealing substantially planar surfaces such as roofs or the like, said membrane being essentially water- and steam-tight, characterized in that said membrane does not contain any bitumen or bitumen derivative and also characterized in that said membrane is essentially formed of at least one thermoplastic (co)polyurethane or thermoplastic (co)polyamide, thus ensuring the essentials of said sealing functions, said thermoplastic (co)polyurethane(s) or thermoplastic (co)polyamide(s) each containing at least one natural monomer that is integrated into the (co)polymer during the polymerization(s) thereof.
摘要:
The present invention concerns a device for sorting and concentrating electromagnetic energy impinging a surface of said device, said surface comprising at least one plasmonics-based surface structure or similar structure of periodic or quasi-periodic surface topography. Device characterised in that said surface (V) is provided with at least two such surface structures (2), acting as individual concentrator structures, which are at least partially spatially overlapped or superposed.
