In order to overcome the single event function interrupt and SA failure,this paper proposes and implements a new way to design circuit,i.e.dynamically reconfigurable adaptive circuit design method.We load a Microblaze which is a soft CPU in FPGA as a motion control part of the circuit,as well as use some place of FPGA as evolution pool to find target circuit.Microblaze known input and the corresponding output applies genetic algorithm to search evolution pool.Depend on it,we successfully design and implement a DC Motor control system,besides,we carry out theoretical analysis on this circuit reliability and simulate circuit function repair test of SA fault,the result demonstrates that compared with the traditional circuit,this circuit and has a high reliability.

Low-voltage switchgears are a combination of several components such as circuit breakers, lightning arrestors, current transformers, protection panels, and disconnectors. They are used to effectively control and distribute electric power across residential, commercial, and industrial premises in order to protect electrical circuits and equipment from unregulated power spikes. Low-voltage switchgear products mainly include panel boards, distribution switchboards, and switches.

Power tools are used to develop products with increased ease and convenience. There are several types of power tool such as engine-driven power tools, electric power tools, and pneumatic power tools. Engine-driven power tools use gasoline for their operation, whereas pneumatic power tools operate with the effective deployment of compressors. Power tools are adopted for several operations such as screw driving, drilling, chiseling, planning, routing, sanding, buffing, polishing, and leveling. In addition to being used in the Residential sector,power tools are adopted by several companies across industries such as Automotive, Infrastructure, Construction, Woodworking, Aerospace, and Electrical and Electronics.

NASA is developing new portable life support system (PLSS) technologies, which it is demonstrating in an unmanned ground based prototype unit called PLSS 2.0. One set of technologies within the PLSS provides suitable ventilation to an astronaut while on an EVA. A new component within the ventilation gas loop is a liquid-to-gas heat exchanger to transfer excess heat from the gas to the thermal control system s liquid coolant loop. A unique bench top prototype heat exchanger was built and tested for use in PLSS 2.0. The heat exchanger was designed as a counter-flow, compact plate fin type using stainless steel. Its design was based on previous compact heat exchangers manufactured by United Technologies Aerospace Systems (UTAS), but was half the size of any previous heat exchanger model and one third the size of previous liquid-to-gas heat exchangers. The prototype heat exchanger was less than 40 cubic inches and weighed 2.57 lb. Performance of the heat exchanger met the requirements and the model predictions. The water side and gas side pressure drops were less 0.8 psid and 0.5 inches of water, respectively, and an effectiveness of 94was measured at the nominal air side pressure of 4.1 psia.
