摘要:
A mobile self-powered videoimaging, video communication, video production (VCVP) system designed specifically for health care industry that provides high-resolution audio, video and data communications, production and recording capabilities at hospital operating room/procedure room or field environments for transmission to other remote locations. The VCVP system generally comprises a mobile platform with a plurality of cameras, at least one being mounted on an extensible boom for overhead imaging of surgical procedures. An array of video production equipment is rack-mounted inside the platform, as is an array of network teleconferencing equipment. The mobile imaging system may be parked at a convenient location in an operating room or other environment and controlled by a single operator. As the surgery proceeds, the operator can multiplex the camera signals into a live high resolution video/audio feed that is networked in real time for teleconferencing, and/or recorded to a hard drive or in any known format such as Mini-DV, S-VHS, VHS and DVD as desired.
摘要:
The metal sheet of the invention includes means for fixing it to a support and a seal gasket laid out along these means. The fixing means comprise at least one lumen provided on the metal sheet by punching, with a cavity for receiving a head of a fixing component corresponding to a metal sheet portion protruding on the opposite face and a washer for transferring stresses between the metal sheet and the support on said protruding portion.
摘要:
A movable blade for a turbomachine, the blade including at its distal end a top portion including opposite first and second side edges and upstream and downstream sealing wipers. Each of the first and second side edges has a substantially Z-shaped profile between the upstream and downstream wipers. On a side of the first side edge, the platform includes a first outwardly projecting rim not connected to either of the upstream and downstream wipers. The platform includes a second outwardly projecting rim, the second rim including a downstream portion connected to the downstream wiper and extending along the second edge, and an upstream portion extending the downstream portion as far as the upstream wiper, and set back relative to the second side edge.
摘要:
The object of the present invention is colorless inorganic glasses, as well as products manufactured from said glasses. Said glasses are of the type containing copper halides or copper cadmium halides and having a sharp optical absorption cutoff between 370 nm and 425 nm essentially having the composition below, expressed in cationic percentages: 23-73% SiO2 15-45% B2O3 0-24% Al2O3 0-12% Li2O 0-20% Na2O 0-12% K2O 0-5% CaO + BaO + SrO 0.125-1% Cu2O 0-1% CdO 0-5% ZrO2 with 0-1.75% Cl 0.25-2% Cl + Br 0-2% Br and 0-2% F; the Cl, Br and F contents being themselves expressed in percentages by weight of the total composition; with an adequate amount of reducing agent(s) which is (are) advantageously selected from SnO2, As2O3, Sb2O3 , and mixtures thereof, in order to have mainly, in said glasses, the copper in the form of cuprous ions (Cu+), and therefore glasses which have neither a red coloration, nor a blue green coloration; and the residual yellow coloration of which is minimized.

A microstructure for chemical processing and manufacture is disclosed. The microstructure includes a plurality of microchannel walls constructed of glass, ceramic, glass-ceramic or combinations of these materials, which define at least one microchannel for accommodating chemicals to be processed. At least one coating layer including a catalyst support and a catalyst is adhered to the plurality of microchannel walls. A method of manufacturing a microstructure for chemical processing and manufacture is also disclosed.
摘要:
A method for loop distribution of a plurality of data blocks corresponding to objects fragments, or aggregates of objects such as alphanumeric messages, screen pages, graphic objects integrated in pages, and/or sound sequences designed to be restored by restoring means. Data blocks are distributed by stacking them into several stacks corresponding to different distribution priorities. This operation is repeated by sampling outputs of each stack based on the distribution priority of the stacks.
摘要:
A headrest including fixed rods intended to be secured on the backrest and extending substantially vertically, a mobile frame slidably assembled on the rods, and a lock associated with the mobile frame and slidably guided thereon along a horizontal direction, to be able to lock the frame on the rods in a plurality of positions. The headrest includes a cross-piece connecting the upper ends of the rods, the cross-piece and the lock respectively including notches and teeth arranged to cooperate together to be able to lock said frame with respect to the cross-piece in any of said plurality of positions.
