A trademark is a word, phrase, symbol or design, or a combination of words, phrases, symbols or designs, that identifies and distinguishes the source of the goods of one party from those of others.
Do Trademarks, Copyrights and Patents protect the same things?
No. Trademarks, copyrights and patents all differ. A copyright protects an original artistic or literary work; a patent protects an invention.
As pointed out in the Wiki article on design patents, an object (like the Coca-Cola bottle shape) can be both covered by a design patent and a trademark. As you mentioned, a design patent runs out after a certain amount of time, but a trademark is valid as long as it is used in commerce. Also, from this article:
In Qualitex Co. v. Jacobson Prods. Co., the U.S. Supreme Court held that color alone may be protected as a trademark, “when that color has attained ‘secondary meaning’ and therefore identifies and distinguishes a particular brand (and thus indicates its ‘source’).” The Court held color may not be protected as a trademark when it is “functional”. There are two types of functionality: “utilitarian” and “aesthetic.” A color is functional under the utilitarian test if it is essential to the use or purpose of the product, or affects the cost or quality of the product. A color is aethestically functional if its exclusive use “would put a competitor at a significant non-reputation-related disadvantage”. If color “act(s) as a symbol that distinguishes a firm’s goods and identifies their source, without serving any other significant function,” it can be protected as a trademark.
If you work around lots of multimeters, as I do, Fluke certainly has distinguished itself by looks. So, don't start up your new package delivery company and paint all your box trucks a certain color brown, don't sell jewelry in little boxes that have a certain shade of blue, and don't design your housing insulation products to be pink. However, I believe you could sell tractors that are a certain shade of green because within that context, green is identified as a functional color.
and pissed in a number of esoteric theories cheerios
I'm not inclined to think this is the case. I think their result was many orders of magnitude over the previous measurement because there was only one other measurement made in this frequency range. The previous experiment was a torsion bar experiment done in a modest-sized lab. According to the LISA folks:
In general, a ground-based interferometer is limited to frequencies above about 10 Hz because of seismic noise
I didn't read the torsion bar paper to see what they did to eliminate noise sources.
Wow, I didn't know the problem was so widespread that there is a whole web site devoted to it. I ended up ordering what I needed from Digikey, but that site probably would have saved me some time as I tried to narrow down what I needed. The good news is that if anyone is having issues with their LCD screens, the fix is really simple.
The shame of it all is that, this scenario is exactly what Radio Shack was so darn nice for back in the day.
I've noticed several design suggestions in your code.
