Multiple mode data communication system and method and forward and/or reverse link control channel structure

A multiple mode data communication system and method provides the flexibility to schedule wireless unit transmissions and/or allow the wireless unit to transmit autonomously. In certain embodiments, the wireless units can transmit autonomously and/or use scheduling depending on the data rate, the length of the data packet or the type of data. For example, the wireless units can transmit autonomously at lower data rates and use scheduling at higher data rates. Thus, the multiple mode system enables wireless unit transmissions to be scheduled and/or be transmit autonomously, and wireless units can simultaneously operate in different scheduling and/or autonomous modes. Depending on the embodiment, the system can provide even greater flexibility in operation by permitting wireless units to be scheduled by a single base station, scheduled by a multiplicity of base stations simultaneously or otherwise, via coordination between base stations, scheduled by a multiplicity of base stations in an uncoordinated and asynchronous manner, allowed to transmit autonomously, and/or allowed to transmit autonomously under base station supervision (i.e. rate control/adjustment by the base station). Additionally, a forward and/or reverse link control channel structure is provided which can be used to implement the multiple mode data communication system and/or support various features enabling increased throughput over a shared data channel in a wireless communications system.

Seven-degree-of-freedom external skeleton type teleoperation main hand

The invention relates to a seven-degree-of-freedom external skeleton type teleoperation main hand. The seven-degree-of-freedom external skeleton type teleoperation main hand is composed of an external skeleton main hand portion, a driving unit and a support. The external skeleton main hand portion comprises an arm wearing portion and a singular configuration adjusting unit. The arm wearing portion is worn on the upper limb of an operator; the singular configuration adjusting unit provides rotation in two directions; the singular configuration of the adjustable external skeleton main hand can be carried out on the edge of working space; the driving unit is composed of motors, harmonic reducers, encoders, torque transducers, transmission wheels and the like; power is transmitted through steel wire ropes; and the weight of the arm part is greatly reduced. The support is used for fixing the external skeleton main hand portion and the driving unit and can achieve height adjustment and gravity balance of the arm. The seven-degree-of-freedom external skeleton type teleoperation main hand is flexible in operation and good in applicability; the arm part is compact in structure, low in inertia and not prone to fatiguing after long-time operation. By means of the seven-degree-of-freedom external skeleton type teleoperation main hand, the operator can remotely control a multi-degree-of-freedom robot through the external skeleton type main operation hand.

Biodegradable medical human body cavity channel inner bracket and preparation method thereof

InactiveCN102908216AGood flexibilityGood securityStentsSurgeryPercent Diameter StenosisCorrosion
The invention relates to a biodegradable medical human body cavity channel inner bracket and a preparation method thereof. The biodegradable medical human body cavity channel inner bracket is prepared by performing crosswise weaving and surface coating treatment on a single or a plurality of degradable magnesium alloy long wires, and very high flexibility, so that the stimulation and damages of the bracket on the inner walls of the blood vessels and esophagi are lowered to the maximum extent; the bracket can be degraded and absorbed by a human body after operation and healing, so that the problem of endotheliosis restenosis caused by long-time existing of a non-degradable bracket in vivo is solved; due to the adoption of a surface degradable ceramic coating and a high-polymer film dual-protection layer, the corrosion resistance of the magnesium alloy wires can be effectively improved, and the degrading speed of the magnesium alloy wires is controlled; carried medicaments have long-term treating effects through slow release; the problem of difficulty in X-ray development of a light metal magnesium alloy is well solved through a carried developing agent; and the biodegradable medical human body cavity channel inner bracket can be used for expanding and supporting human body inner tube cavity channels such as narrow blood vessels, esophagi, bile ducts, intestinal tracts or urethrae and the like, and belongs to the technical field of manufacturing of medical instruments.
