Dear Reader,


BEI Holiday WreathThe Holiday season is upon us with the end of 2010 not far behind.  The year has had it's ups and downs depending on what part of the world you live in.  At this holiday time of year, we at BEI Sensors wish you the all the best.  Health, happiness and prosperity for the new year.  Enjoy some relaxing time with friends and family and we'll see you again when the calendar turns to 2011.

Santa's Helpers
Since this is our holiday newsletter, rather than feature a particular BEIBEI Santa Sleigh product or service in this space it seemed right to provide a little holiday cheer instead.  So with apologies  to Clement Clarke Moore  I bring you "A visit from St. Nicholas".

'Twas the night before Christmas, when all around the shop floor;
All employees were working to try to produce more.

Their hands were really flying with screwdrivers and pliers,
They were working so fast I expected some fires!


Yes things were really humming, the last push of the season

It bordered on crazy with no rhyme or reason;

So I turned back to my desk, paperwork to be done

And tackled that stack, though it hardly was fun;

 

When out in the plant there arose such a clatter,
I sprang from my work to see what was the matter.
Away down the stairs I flew like a flash,
Flung open the doors, and saw the big crash.


Our products were scattered all over the ground,
And horrified faces were all gathered 'round;
When, what should appear as if sprung from the shelves,
But a man in bright red and some quick little elves.


He gave out his orders, so lively and quick,
I knew in a moment it must be St. Nick.
More rapid than lightning his workers they came,
And he whistled, and shouted, and called them by name:
"Now! Driver, now! Welder, now! Tester and Blaster,
"On! Painter, on! Cleaner, clean up this disaster.

His eyes - how they twinkled as they flashed 'round the scene.

This was not the first calamity that he'd ever seen!
His droll little mouth sent orders around,
And his team leapt to work with hardly a sound;


He was chubby and plump, a right jolly old elf,
And I rolled up my sleeves in spite of myself;
We all worked together and made the mess right

I swear there was magic at work there that night.


We had never quite seen such orderly work,
And soon we were done and then he turned with a jerk,
With high fives and fist bumps to mark the completion

Somehow we had managed to finish the season.


He sprung out the door, to his team gave a whistle,
And away they all flew, like the down of a thistle:
With joy we exclaimed, ere he drove out of sight -
Happy Christmas to all, and to all a good night.

 
Many sides to Christmas

BEI Christmas TreeMany things have been said about Christmas, Santa Claus and the holiday season in general over the years.  Here are some of the more amusing and poignant ones.

  

"Christmas is a time when everybody wants his past forgotten and his present remembered." -Phyllis Diller

  

"Christmas is a time when kids tell Santa what they want and adults pay for it. Deficits are when adults tell the government what they want and their kids pay for it." - Richard Lamm

 

 

"I stopped believing in Santa Claus when I was six. Mother took me to see him in a department store and he asked for my autograph." - Shirley Temple

 

"Santa Claus has the right idea. Visit people once a year." - Victor Borge

 

 

"There are three stages of man: he believes in Santa Claus; he does not believe in Santa Claus; he is Santa Claus." - Bob Phillips

 

"Remember, if Christmas isn't found in your heart, you won't find it under a tree." - Charlotte Carpenter.

Can You Solve It?
"Help" came the voice from over the phone, "I've never seen this happen before.  It's a disaster, the kids will be so disappointed."  After assuring the caller that we would be able to help and getting him calmed down we were able to ask a few pertinent questions.

 

The problem at hand was that his candy cane striping machine wasn't working correctly.  Everything would be moving along fine then all of a sudden the stripe spacing would "go haywire" and the stripes didn't look right anymore.  We were able to determine that the machine was designed to hold a straight candy cane in a chuck that was very similar to a lathe.  Then a stripe painting arm would move along the length of the candy cane as it spun around.  An encoder would monitor the cane rotation and advance the stripe painting arm based on the rotation of the cane.  When things went "haywire", the stripe painting arm was advancing at a slower rate than it was supposed to, creating "crowded stripes".  What was going on?

 

Answer:  This was an intermittent problem which points to a possible loose connection.  Since the painting arm did not stop completely (it just slowed down) we were suspicious that only one of the data channels was affected.  We asked that he double check the connections both at the encoder and the controller and get back to us.  A few minutes later, the call confirmed our suspicions.  The cable connection at the controller was intermittent on the "A" channel resulting in an intermittent loss of counts.  The wire was reconnected more securely this time and perfectly striped candy canes were on their way.

Ice is nice

BEI Ice SculptureWhat better way to celebrate the winter and all the really cold weather that has hit the northern hemisphere?  How about a little ice sculpture to show that the frozen stuff actually has a beautiful side as well.  One example is shown to the left.  Yes, it really is made entirely of ice.  Sort of makes this normally slimy subject a bit more approachable wouldn't you say?  If you want to see a collection of 40 photos from ice festivals around the world, then just click on the photo and you'll get an eyeful!  Some are amazingly intricate or whimsical, but all of them show what a creative media that ice can be.  Stay warm and enjoy!

THANK-YOU

We hope you enjoyed this holiday-themed newsletter for December. Come join us again in 2011 and remember that we'll still be around to help with your sensor needs in the new year.

Sincerely,
