With the issue of Galaxy S4, no matter the medias of foreign countries or Chinese medias have all introduced a lot of assessment and test and experience article about this machine, everybody understands its appearance and characteristic certainly. Until everybody lose feeling of freshness gradually, expose a series of the intersection of Galaxy S4 and wireless photo to charge suit on the net, but uncertain it can plane merchandize synchronously conveniently now.
Galaxy S4 is wireless to charge suits
According to photo exposed, Galaxy S4 has adopted a charging board as the wireless charged medium too. However, compare with carefully, find, if wanted to carry on wirelessly and is charged, need, allocate one dedicated back over alone also, as for the thickness and charged result of back over, there is no precise news at present.
Besides charging suits in wireless, have also exposed the firmware sectional drawing of a series of Galaxy S4 on the net. Can be found out from the picture, this machine has adopted the newest Android 4.2.2 system, the whole firmware magnitude is 1549.8MB.

First, LED organosilicon outdoor display screen encapsulate the exquisite performance requirement of glue
Organosilicon encapsulates the glue to tell from use, mostly apply to an external environment, certainly the special place, apply to bottom or moister environment,etc.. So, the main performance requirement is to say that is ground ” The weather ability ” ,But direct with the weather ability and the keyword with close ties is mainly as follows, adhesion, adhesive force, tensile force, flexibility, it is high specialized nouns such as wearing out, acid-base environment,etc. at low temperature.
The weather ability mainly reflects after encapsulating the use of glue, under various environments, for example: Permanent high temperature, permanent low temperature, permanent humidity, there are outdoor acid-base rain, sunshine, wind and snow,etc., in addition whom special purpose require have ultraviolet resistance and high heat conduction, high impedance performance requirement lay the application all the year round right, high and sour and alkaline, glue good adhesion, adhesive force, tensile force, flexibility, insulating quality, waterproofing,etc. of remaining stable after solidifying.
Second, the intersection of LED and whom the open air reject encapsulate glue in Application Process, from quality being good and bad to come on, say, mainly in what phenomena are displayed

When adopting the digital signal of light-coupled isolation to carry on control system design, the transmission characteristic of the photoelectric coupler, namely transfer rate, often become the determing factor of the systematic maximum message transmission rate. In a lot of bus type structural industry observes and controls the system, in order to prevent the mutual interference between every module, do not reduce the baud rate of the communication, the isolate between the effectuators that we have to adopt the high-speed photosensitive resister at the same time. The commonly used high-speed photosensitive resister has 6N135/6N136, 6N137/6N138. However, the price of high-speed photosensitive resister is higher, lead to the fact the design cost is raised. Recommend two kinds of methods to raise the switch speed of the ordinary photosensitive resister here.
The distributed capacitance existing because of photosensitive resister, cause influence on the transfer rate, distributed capacitance Cbe and Cce exists within the phototransistor. Because the electric current of the photosensitive resister transmits lower, its load resistance of collecting electrode can’t be too small, otherwise the excursion of the output voltage has been limited. However, the load resistance should not be too big, RL the bigger the load resistance is, because of the existence of distributed capacitance, the worse the frequency character of the photoelectric coupler is, it is th...
