A001 Develop a way to track specifications Jason October 3, 2008 October 10, 2008 October 8, 2008 Status already included, trying to find way to correspond to which customer requested it
A002 Create sketches or some way to display design Brian October 3, 2008 October 10, 2008 October 10,2008
A003 Develop Eye-Wear Weight Specifications Brian October 3, 2008 October 10, 2008
A004 Set up a specification for Time to setup Dave October 3, 2008 October 10, 2008 October 10, 2008 Placing Glasses with cameras will take less than a minute to set up, A time to set up the electrodes for both the EEG and EOG need to be determined based on the type of electrodes (Approximately 10 minutes). Also a time that the software needs to be calibrated needs to be determined once the software is done and running (Approximately 10 Minutes).
A005 Revise System Level Block Diagram Jason October 3, 2008 October 10, 2008 October 8, 2008 Revision complete, reviewing with customer for quality, uploaded on edge, adjustments in the future can always be made
A006 Develop a Requirements sheet in addition to customer needs Brian October 10, 2008 October 17, 2008
A007 Develop a separate "Wish List" apart from customer needs, and requirements Jason October 3, 2008 October 10, 2008 Octogber 21, 2008 Focusing only on needs and requirements
A008 Selection of Data Storage Method Matt October 3, 2008 October 10, 2008 October 9, 2008 Confirming calculations and moving forward with selecting storage device (Compact Flash). Will close after meeting with Mark Indovina
A009 Establish End User Reprogramming Plan Matt October 3, 2008 October 10, 2008 October 8, 2008 CD(s) will be provided along with documentation in case a situation occurs where the programs need to be re-installed. These will be delivered with the final product.
A010 Signal Interfacing Selection Jason October 3, 2008 October 10, 2008 October 8, 2008 Consult System level block diagram and biopotentials block diagrams for signal traces, will examine further in the Structure breakdown document
A011 Assess required Battery Power Dave October 3, 2008 October 10, 2008 October 10, 2008 Power Required to Run the Single Board Computer is rated to be 7.5W, the power needed to run the Video Processing board is rated to be 7.5W, The calculated power to be used by the instrumentation board is 2.5 W, 3W will be a worst case scenario for the instrumentation board. The total power required for these components is 18W, Power conversion board and camera power usage still need to be considered.
A012 Assess necessary Battery Heat dissipation Jelani October 3, 2008 October 10, 2008 Made preliminary calculations based on joules of energy used by battery for one hour and determined an estimated temperature after one hour. Certain properties were estimated and need better definition.
A013 Choose Battery Charging method Omar October 3, 2008 October 10, 2008
A014 List of info needed for individual tasks Brian October 3, 2008 October 10, 2008
A015 Selection of Power Distribution Board Omar October 3, 2008 October 10, 2008 October 9, 2008 Our SBC (PM-LX-800) needs the following inputs +12V, +5V and -12 V. I found a power distribution board that is pretty much meant for this SBC. The part number is PM-P001 and the link to the data sheet is here: http://www.icpamerica.com/files/pm_p001_datasheet.pdf

I don't know exactly how much it costs, but I'll know by tomorrow morning (2 different vendors are calling me Friday morning). Also, the distribution board has a 5VSB output that can be used to power Dave and Jason's Instrumentation board. The board is about the same size as our SBC/Video board (3.5x3.7). I feel pretty confident we can use this board so I'm gonna close this action item.

UPDATE: Matt pointed out a similar board, but with a smaller watt rating (40W as opposed to 100W) that he recommends we use. Here is the link:

http://www.icpamerica.com/products/power_supply/dc_to_dc/pm_p004.html

It still has all the outputs we need to power our SBC and it's also $50 cheaper.

A019 Selection of A/D Conversion method & Gain Control capability Dave & Jason October 3, 2008 October 10, 2008 October 8, 2008 Selected PSOC chip for gain control and A/D multiplexing, help simplify design
A020 Meet with customer to approve of changes Everyone October 3, 2008 October 10, 2008
A021 Noise considerations for enclosures Jason October 3, 2008 October 10, 2008 October 8, 2008 Filtering will be used to remove high frequency noise, other considerations are being explored. As far as biopotentials are concerned frequency range is too small to require any shielding, examine single board computer requirements further*.
A022 Examination of lead times and manufacturing time Jason October 3, 2008 October 10, 2008 October 9, 2008 Talked with Ken concerning Biopotential boards lead time, shouldn't be an issue, need to formally document to close.
