eMMC (Embedded Multi Media Card)是MMC協會訂立、主要針對手機或平板電腦等產品的內嵌式存儲器標準規格。eMMC在封裝中集成了一個控制器,提供標準接口并管理閃存,使得手機廠商就能專注于產品開發的其它部分,并縮短向市場推出產品的時間。MMC的應用是對存儲容量有較高要求的消費電子產品。2011年已大量生產的一些熱門產品,如Palm Pre、Amazon Kindle II和Flip MinoHD,都采用了eMMC。為了確認這些產品究竟使用了何種存儲器,iSuppli利用拆機分析業務對它們進行了拆解,發現eMMC身在其中。附件為介紹EMMC5.1標準的數據手冊.

摘要:本系統以ICL8038集成塊為核心器件,制作一種函數信號發生器,制作成本較低。適合學生學習電子技術測量使用。ICL8038是一種具有多種波形輸出的精密振蕩集成電路,只需要個別的外部元件就能產生從0.001Hz~30KlHz的低失真正弦波、三角波、矩形波等脈沖信號。輸出波形的頻率和占空比還可以由電流或電阻控制。另外由于該芯片具有調制信號輸入端,所以可以用來對低頻信號進行頻率調制。關鍵詞:函數信號發生器頻率調制Abstract:The system ICL8038 integrated block as the core device,producing a kind of function signal generator,producing low cost.Suitable for students to learn the use of electronic technology measurement.ICL8038 is a kind of multi-precision oscillator waveform output integrated circuits,a separate external components only need to be able to generate from the 0.001Hz ~30KHz low-distortion sine wave,triangle wave,square wave pulse signal,etc..Output waveform of the frequency and duty cycle can also be controlled by a currentor resistance.In addition,as the chip has a modulated signal input terminal,it can be used to low-frequency signal is frequency modulation.

1-1單透鏡這個例子是學習如何在ZEMAX里鍵入資料,包括設置系統孔徑(System Aperture)、透鏡單位(Lens Units)、以及波長范圍(Wavelength Range),并且進行優化。你也將使用到光線扇形圖(Ray Fan Plots)、彌散斑(Spot Diagrams)以及其它的分析工具來評估系統性能。這例子是一個焦距100mm、F/4的單透鏡鏡頭,材料為BK7,并且使用軸上(On-Axis)的可見光進行分析。首先在運行系統中開啟ZEMAX,默認的編輯視窗為透鏡資料編輯器(Lens Data Editor,LDE),在LDE可鍵入大多數的透鏡參數,這些設置的參數包括:·表面類型(Surf:Type)如標準球面、非球面、衍射光柵..等·曲率半徑(Radius of Curvature)·表面厚度(Thickness):與下一個表面之間的距離·材料類型(Glass)如玻璃、空氣、塑膠.…等:與下一個表面之間的材料
