COLOR AC-PDP ENHANCEMENT OF LOW LEVELS IMAGE QUALITY WITH DYNAMIC MODIFYING SUB-FIELDS CODE

Based on the ＂Grayscales average distribution＂ method which equally distributes the input gray levels to output gray levels, three improved methods named： ＂Reduce the gray range expressed by the less significant subfields＂, ＂Low levels preset＂ and ＂Modify the exponent of inverse-gamma function＂ are proposed in this paper. Using these methods, the inverse-gamma relation subfields code can be obtained easily which can improve the low level expressions of AC-PDP. And a program, ＂ gray scales distribution validate program＂, which can enhance the expressions of the demanded gray levels range, is also proposed in this paper.     

A New Proposal of Inverse-Time Characteristics for Overcurrent Relay Based on Microcomputer

The conventional time function of electromechanical relays is hard to coordinate with other relays．In order to promote the application of inverse-time overcurrent relays，a new time function for microprocessor-type relay is proposed．The setting of the trip time for this relay is performed by determining the shortest trip time and the longest trip time，respectively．The results of analysis show that with the new time function，the inverse-time overcurrent relay is easy to coordinate with other relays and has a comparatively shorter trip time，and that the fault happens in the protective zone．
