It works well! Great rainbow ribbon cable!

To Peter Alfke, Symon and John Larkin: Today (April, 24th), we get back the PCB board to implement the transmission of signal using ribbon cable. We use a 47Ω serial-termination resistor and a 1.5 meter long rainbow ribbon cable. It works well. However, one of the waveforms is a little bit strange. It is actually not as good as the waveform we get using a normal single cable in the simple experiment previously. The follow figure is the strange waveform which is on the resistor, can you tell me why?

The simple experiment for prolonging the cable of our CMOS image sensor

To Peter Alfke, Symon and John Larkin: Thank you for your help. We had design a PCB board to test the method you told us and we could get it next Tuesday (April, 24th). What' more, we do a simple experiment to have a simple qualitative analysis. The conclusion is fairly positive. Thank you! If we have further information, we will also tell you.

1, The original waveform of PCLK (3.3v/24MHz) output pin:







2, A resistance of approximately 56Ω(three resistors in serial) is used as source terminator and a 1 meter long normal cable is used as transmission line. The following figure is the waveform on the far end of the cable.





3, Ditto. Waveform on the series-termination resistor. The magnitude really drops because of the reflection.

25 Words That Can Hurt Your Résumé
October 04, 2005 by Alan

你的阅历真的很丰富吗？在你投放自己的简历之前，你一定要证明这一点。

当求职者尝试着向潜在的雇主推销自己时, 简历中经常地充斥着模糊的言语，人力资源经理会一目了然,按照Scott Bennett的说法, 这样的求职者不过是“简历文体”作者罢了。相反, 最成功的求职者避免在他们的简历中出现这些隐晦的词语，而倾向于突出自己的成绩。

不要用空泛的词语表达你的工作理念,而要使用简要的、具体的例子展示你的技能。换句话说, 展现,但不必陈述。（show, don’t tell.）

Bennett举出以下几个例子：

不要用… “在快节奏的环境里把工作做得游刃有余”
而尝试… “每天晚上，我都会为120名左右的急诊患者登记挂号”

不要用… “卓越的书面表达、交流能力”
而尝试… “为11000位用户写了专业术语的指南”

不要用… “拥有跨部门的意识，善于团队合作”
而尝试… “与客户合作, 加快供应和销售部门的反应速度，从而防止对客户服务的干扰。”

不要用… “在分析客户需求上有过成功的案例”
而尝试… “创造和实施了一种全面的需求评估机制，来协助对服务和员工预测需求”

最糟糕的“违规者”
勤勉和雄心是褒义词, 对不对?但如果你不能提供坚实的事例来支持你的陈述，那么人力资源经理也不会被你说服。Bennett 建议是：在你的简历中，对这些听上去美妙无比、但实则空洞无味的词语要额外小心——
