Used by the MSRA beams for 8 years so far.

These beams have never missed the passage of a single snowmobile, ATV, dune buggy, water truck, beer truck, mud bogger, GTO, Camero, supercharged Duce-coup, or pink Cadillac.

Some of the beams have been run over by open-mod snowmobiles multiple times in the same race day. The worst that has happened to them is the external batteries on the transmitters exploded on impact, blasting H₂SO₄, sulfuric acid, everywhere. However, after attaching a new battery, and resetting the beam they continued to work.

They have worked in heavy/wet snow storms that stopped the race because we couldn't see the end of the track, yet the beams continued operating, unaffected by the snow.

The results of all races run with these beams (who won) have never been challenged in their 8 years of service.

They have been used in -20F on a clear day in the high glare conditions on lake ice. They can reject external white light (full spectrum) of 50,000 lux (Pulnix* specification).

They are currently used in grass-drags where the dust and dirt coats the beam lenses, yet they remain unaffected.

They have rattled around in the back of my truck, and in my slide-in camper for 8 years and 1,000's of miles, and I have never had to repair the beams. Only the stand due to being run over.

However, what I have done is to design  a  digitally based modification to the Pulnix technology. This modification, both internal to the device as well as an add-on circuit board makes race vehicle detection a decisive event.

This application is also "patent pending".

Both notices are etched into the circuit boards and they are serialized to track what boards are sold where, and so that I will know what revision you have. That way I can better take care of you.

Copying this application or the modifications to the Pulnix* beams for your own purposes is a violation of the copyright and patent laws and will be prosecuted.

Here are some specifications that have been proven reliable by 8 years of service.

1. Reaction time - 0.002s +/-0.0005s

   An object moving at 100mph covers 3.52" in 0.002s. This means a taped ski loop would trip the beam at 100mph.

2. Opposing transmitter and receiver.

   No reflectors means no chance of a shiny, reflective, vehicle going by without being seen because it reflected the beam as well as the reflector did.

3. Active output. (pull up, pull down)
4. Short-circuit protected output.
5. Output swing 0V to V⁺ -1.5V
6. Operating voltage (V⁺) 10-24Vdc
7. Supply current 

   receiver
   transmitter
