Abstract: This paper searched a way in order to solve relations between the structures and locking performances for vehicle safety-belt retractor, introduced the emergency locking retractor operating principles, including roll-up mechanism, bearing-strength mechanism, sensitive locking organization. Established the movement equations include the car-body which accelerates, the car-body lean and the pull out strap which accelerates, according to the equations of motion may the design performance parameters and structure parameters. Based on above research, applying MSC.ADAMS to dynamic simulation analysis, to make a analysis between the turn angle of strap-shaft and time, provided a check mean for improving performance of retractor, so as to accord the compulsorily standard ECE. R16: uniform provisions concerning the approval of safety-straps, restraint systems, child restraint systems and ISO fix child restraint systems for occupants of power-driven vehicles and GB14166-2003: safety strap and locking system used for adult passengers of vehicle.

Abstract: This paper describes multi-scale interface for bio and medical engineering based on MEMS technology. MEMS technology can provide various interfaces for biomedical application corresponding to hierarchical components of living organism such as cell, tissue, and organ. This paper mainly deals with small, soft, and safe (S3) micromachine as multi-scale interfaces for medical application. Micromachine is small in nature. S3 micromachine is based on its soft and flexible structure and safe driving principle. These features are suitable for advanced medical tools for minimally invasive medical operations. S3 micromachines-based medical tool has been applied to a retractor for spacing in front of the endoscope at our early stage. This paper also presents the S3 micromachine as a surgical tool for a cell sheet transplantation in an eye.
