A card edge connector includes an elongated housing with a pair of latches disposed at opposite ends thereof and defining a mating groove in the housing and between said pair of latches. A first wall and a second wall are formed at opposite sides of the mating groove, on which a plurality of conductive terminals are mounted. A key protrudes into the mating groove from the first wall with a distal end sinking into the second such that the second wall can be molded in an uninterrupted manner without the joint of the key.

Methods for preparing iron source material and ferrous oxalate for lithium ferrous phosphate are disclosed. One method comprises bringing solution containing ferrite and soluble non-ferrous metal salts in contact with oxalate solution; wherein said method of contact is to allow a flow of the ferrite solution containing ferrite and soluble non-ferrous metal salts to come in contact with a flow of oxalate solution. Another method comprises brings a stream of ferrite solution in contact with a stream of oxalate solution, wherein the flow rates of the ferrite solution and oxalate solution give the resulting slurry a pH of 2-6. The ferrous oxalate particles produces by the methods of the present invention are regularly shaped and have small and evenly distributed diameters. Lithium ferrous phosphate made from iron source material and ferrous oxalate prepared using the methods of the present invention has small particle diameter, homogeneous particle size, good electrical conductivity, and superior electrochemical properties.

Defect mitigation in display panels. Defects in a display panel are mapped, and the defect information is associated with the display system or associated with the panel. During panel operation, the values of pixels neighboring defective pixels are altered to minimize their visibility to the observer. In a first model, luminance error caused by a defect is compensated by adjust neighboring pixels. In a second model, Error in luminance and one of the two chrominance channels is compensated by adjusting neighboring pixels. The defect mitigation methods seek to shift the errors introduced by defective pixels into high spatial frequency elements and chromatic elements, which the human eye is not sensitive to.
摘要:
The present invention relates to additives for electrolytes of lithium ion secondary batteries that include one or more of the following: 1,3-propane sultone, succinic anhydride; ethenyl sulfonyl benzene, and halobenzene. It can also include biphenyl, cyclohexylbenzene; and vinylene carbonate. The weight of said 1,3-propane sultone is between 0.5 wt. % and 96.4 wt. %, said succinic anhydride is between 0.5 wt. % and 96.4 wt. %; said ethenyl sulfonyl benzene is between 0.5 wt. % and 95.2 wt. %; and said halobenzene is between 0.5 wt. % and 95.2 wt. % of the weight of the additive. Batteries with electrolytes containing said additives have improved over-charge characteristics and low temperature properties, and reduced gas generation during charging and discharging.
