how to designe a people counter for a room door?

I'd forget the light sensors, way more complicated than is needed. You would need to compare voltage levels in the receiver(for infra red) or use a schmitt trigger (for a LDR[Light dependant resistor]) and there is a simpler way. Pressure pad on the floor. Then just use a 4017 counter chip (It's CMOS and i'm not sure of the number, it's been 2 years since I did electronics)\n\nMind you, depends what it is for and how accurate it is needed. It won't be quite as accurate as a infra red sensor(which would probably be the best method)as people could step over it if it is not that big but even infra red will be confused if two people walk through the door side by side.\n\nThe only method I can think of that is foolproof(besides a computer, a camera and some recognition software) would be a guy with a counter, but not so practicle.

Maybe have people at the door or something asking for tickets. If someone goes to the bathroom, let them know before they leave that they will have to show their ticket again when coming back into the session...

I got it. It's simple, There is no way you can pass through every door once in a FIVE room house, when really it's six rooms, because the outside of the house has an essence of a another room. So it's really six rooms (if it were six rooms, start in a room with an even number of doors ^.-)

No need for photos. It's easy. If you have more then one colored roll, pair them side by side and twist/unravel them. Attach one end to one corner of your room and head towards the center. Tape in place and repeat from all 4 corners, meeting at the same central point on the ceiling in the middle. Cover the tape points with balloons matching the color scheme of the party. Make sure you place balloons in the corners as well.

Get a ShopVac and get a floor-mat. Wipe your feet off before you go in and put a sign on the door that says 'PLEASE WIPE YOUR FEET.' Can't get much more obvious than that.

I'd look in Domino magazine for ideas.  Your party could be themed.  You know, something like "chic steals on a budget".  Or "how to transform your living room in five steps".  Another idea of mine is to ask an Interior Designer to be a special guest at your party.  He or she may have some insider information on decorating that the outsiders aren't privy to.

Go to Lowe's and get a couple of those organizers for hardware, etc. The ones with like 20 little drawers or so. Get a label gun, and voila! That's what a lot of dentists do.

How about a comb binding?\nLike a book the pages are held from top all the way to the botom and they stay open, you can buy a machine to cut the holes in the paper and insert the comb I know the combs can be brought from partners but our machine is about 100 years old and I have never looked for one, you should also be able to go to a printers and get them made up, you could do the one as a sample

I know how frustrating it can be to design and then hear criticism so I hope you take it as constructive criticism.\n\nI don't like the blank space on most of the right side of the page. I think it will look much cleaner if you incorporated the image and all text to the right of it including the WASHROOM SOLUTIONS, AIR CONTROL FAUCETS & FLUSHERS content all in one cell. Then all the content below it to fill the entire WIDTH of the page.\n\nSpeaking of looking clean…I also think with this kind of product you should stay away from the red and yellow colors. Maybe even the grey colors. I think blue gives a refreshing look. You might even want to go with a darker navy blue?\n\nI like the horizontal menu, but instead of text link perhaps a rollover image would look better. Maybe plastic or glass looking buttons (with no grey background), and it would match the products plastic transparent color.

The above answers are correct, assuming that one of the people with the second key would be available to open the second lock.  However, If it was not known if any 1 person would be available to open the lock, it would be nice for ANY two to be able to open the door.  \n\nIn this case, you would need 10 locks and 90 keys. Each person would get one key for each of 9 of the locks, excluding 1 (different) key / lock per person. Therefore, a single person could open 9 of the locks, but it would take any one of the other 9 people to open the last lock, ensuring that your conditions are always met.\n\nIn summary -\n10 locks\n9 keys per lock, total of 90 keys.

Depends on the person. I don't even lock my front door. Most people I know don't even bother knocking - they just walk right in and say "Hi". \n\nI have friends who are completely uptight (in my view) and have to have everything planned out to the smallest detail. I don't drop in on them unannounced. It really shakes up their world for some reason.\n\nThere are no hard rules. Over generalization is the hobgoblin of this society. Remember, one size fits all, fits all equally poorly. Some people like myself would love to be surprised by an old friend. Other people would be so shocked by any alteration of their plans that they would suffer real physical anxiety over not being prepared to “entertain” guests. Whatever. Depends on who you're dropping in on and how well you know them.

Go on Google and type in something like online design program. You might have to put switch the words around or add some other words but online design program should be okay.
