Based on an actual project application background  this paper has put forward a design method of new high reliability aerospace camera controller in-orbit software reinjection instruction sequence which use TSC695F as kernel CPU and process flow of bootstrap receive  cache  checkout and storage update data. Finally  combined with specific test module for camera controller software re-injection  the validity of the software re-injection method raised here has been verified. Still here gives out reference codes of update data package which generated by the ground. 2012 IEEE.   Research and development on the valve-less piezoelectric pump with unsymmetrical corrugation chamber bottom (EI CONFERENCE) 会议论文 2006 IEEE International Conference on Information Acquisition, ICIA 2006, August 20, 2006 - August 23, 2006, Weihai, Shandong, China Li H.; Zhang J.; Li D.; Xia Q.; Wang S.; Lai D. 收藏  |  浏览/下载：16/0  |  提交时间：2013/03/25 The valve-less piezoelectric pump is more suitable for minimization and microminiaturization than the valve piezoelectric pump  especially for the Microelectromechanical System (MEMS) because of its simple structure. However  in order to control the flow direction of the fluid through the pump  some assembles have to be attached outside the chamber. And it is no doubt that these assembles will take some space and hinder its further microminiaturization. In this paper  a novel valve-less piezoelectric pump with unsymmetrical corrugation chamber bottom (UCCB) is presented. It ingeniously takes advantage of the space of the chamber by developing its bottom into a unsymmetrical corrugation shape along the axis of the inlet and outlet. As a result  a series of diffuse pipes and nozzle pipes (or wedge-shaped pipes)  which substitute the regular diffuse/nozzle elements fitted outside the chamber  are alternatively formed between the unsymmetrical corrugation chamber bottom (UCCB) and the piezoelectric vibrator. The piezoelectric vibrator is opposite to the UCCB. And these diffuse pipes and nozzle pipes are able to force the fluid in the chamber to flow along a single direction when the pump works. And then the mathematic model is established to present the relationship between the mean energy loss and the flow rate of the pump. Basing on the mathematic model  the theory on the pump working is analysed. Finally  a real UCCB valve-less piezoelectric pump is manufactured  and the test with it is carried out to verify the theory above-mentioned. 2006 IEEE.
