Here's a more topical "funny" from the CC.

In trying to justify the half-million dollar wall switch from AC Kinetics, Wallach gave the following example:

A perfect example would be a light in a bathroom, which is a room frequently visited during a power failure or any other time. The visit to a bathroom might be three minutes, so where a general power failure product may be on because of power failure conditions, a power failure product that incorporates our Capstone Power Control technology can be turned off. In essence, we're only using it when we need it, and that significantly extends the life of the product.



Sounds great doesn't it? But here again what appears to be a lack of any staff with basic engieering knowledge of ergonomics is apparent.

Applying Occam's Razor to the overly complex and costly solution given in Wallach's example we can recommend a cheap, elegant solution.

Simply include in the lighting fixture a Passive IR Proximity Detector which turns the light on automatically when a body enters the (bath)room and turns it off automatically when the occupant leaves.The circuit is simple and inexpensive and would work whether the lamp was operating on house current or on battery current in power outage mode.

And nobody has to remember to turn off the $500,000 switch -LOL.

(This would also handle power outage lighting for hallways and emergency exit stairwells - no hands required.)

Jeez - why reinvent the wheel?
