Samples Of Board Resolutions: Fill & Download for Free

The ADC on the Uno board has a 10-bit resolution, letting you differentiate to 2^10 (1024) different levels for an analog input.There are 4 good ways I can think of off the top of my head to improve your resolution. The best method depends on how complex you're willing to get and how much better resolution you really need. Most methods will probably get you realistically the equivalent of 2-4 additional bits of resolution (12-14 bits total), except for the separate ADC chip, which could get you an additional 14 bits or so (24 bits total).Data AveragingTake multiple measurements and use an algorithm and averaging to get better precision. For example, one thing you can do is to take 10 (or 100) measurements, throw out the top 10% and the bottom 10%, and average the rest.Pros: Fairly simple, no new hardwareCons: Takes a lot more time to do so many readingsRange AdjustmentYou could adjust the AREF (Analog Reference) Voltage that you're using on the Arduino or adjust the output of your sensor if you only need to be measuring over a very small range. For example if you were measuring temperature and the thermometer gave you 0 to 102.3 degrees, you could measure 0.1 degrees. If, however, you only needed to measure 60 to 70 degrees, you could change the thermometer to output only in that range (through the use of an op-amp) and instead have a resolution of 0.01 degrees, which effectively gets you a more precise reading with the same ADC.Pros: Use the same Arduino board, same analog input, same sampling speedCons: Loss of full range, additional circuitry requiredSeparate ADC chipYou can use a separate ADC chip with a higher resolution that interfaces to the Arduino through Serial, I2C, or SPI. Many are available from electronics suppliers in resolutions generally up to 24-bit for under $10.Pros: You'll get the best resolution availableCons: Additional ADC chip and serial interface add to complexityDifferent Arduino BoardGet an Arduino board with a 12-bit ADC, such as the Arduino Due or the Arduino Zero.Pros: No additional circuitryCons: Additional cost of board might be overkill for benefit provided

Most students do not go through a formal IQ test, and thus data on direct IQ measures would be pretty sparse.However, SAT scores are closely correlated with IQ, much more so than, say, ACT or GRE scores, which depend more on domain knowledge. Different studies peg the correlation between SAT and IQ in the 0.72 to 0.88 range, depending mainly on the particular IQ test. Most students admitted to top colleges take the SAT. This near-100% sampling is the best available data on IQ distribution of those admitted. If, say, 10% sampling of direct IQ measures were available (and it isn't and would cost tens of millions of dollars a year for many years to produce), the data would tell us less about the IQ distribution than the already existing SAT data. The distribution for graduates is going to be similar, given the high graduation rates.The use of SAT as a proxy for IQ is a long-standing academic practice as well. The Study of Exceptional Talent, a long-running program at John Hopkins, uses SAT (taken before age 13 to get more resolution at the high end of the spectrum) as the selection criterion.SAT scores for admitted applicants are easily available from each university. I like this site as a compilation, but keep in mind that the site has no academic or College Board affiliation, so I would not use it as a source for peer-reviewed research. It seems to have solid data though, based on my comparison of a couple of top schools with the data from the school.http://www.satscores.us/(Click on the school name to get more info on distribution rather than just the 25th and 75th percentile that the summary table presents.)UPDATE: To answer the comment, very roughly, 25th percentile at IQ 145 and 75th at 165. Obviously both SAT and conventional IQ tests have trouble resolving in this area and particularly above.

You should have your attorney help you with this. If you don't have an attorney, you really need to get one. This isn't something you can just hack. The ideal approach is for the company to issue additional stock to the new cofounder. This will avoid capital gains issues raised by transferring stock from existing stockholders to the new person. You'll need to come to some agreement as to the amount of stock, and whether he is going to purchase it with cash, services, or some combination of the above.In terms of documentation, you'll want to have the new person sign a restricted stock purchase agreement. This agreement gives the company a right of first refusal in case of any proposed transfer of stock, and should also put the new person on a vesting schedule. The new guy should also sign an IP assignment, transferring ownership of all IP to the company, and you may want some kind of founders' agreement, consulting agreement, or employment agreement. You'll need board resolutions to authorize all this.While it is generous of Adam to point you to the Orrick sample documents, which are generally of good quality, his advice to get a lawyer is spot-on. Don't try to fiddle with those documents yourself. A lawyer that works with startups on a regular basis can determine what you need and guide you through the process - he will be as important a part of your team as the CTO.
