This is old news now - but I'm really looking forward to when the federal decision is made, I'm sure it will make for comedy gold.

It's fundamentally a live recommendation system, and those votes make it work better than anything else (see Digg). I click on a subreddit and I get recommendations for related pages.

I'm talking about one focused idea. I dont want to do your homework for you guys but think "temporal social bookmarking" - social bookmarking and calendar app have a baby. Otherwise you're just rehashing Google Calendar and/or Digg.

No, combine the two played ideas into one novel idea. It's called synthesis, thats what constitutes innovation...

I never said that TBL or Cerf were patent advocates. I am very familiar with their positions on the subject. Even though they released their work to the public with no restrictions, their work was built on top of a ton of prior art that w

Finally! They are a bit late to the gate and are doing this in reaction to Yahoo asserting themselves in the arena.

Highly misleading. You should look into some patents and how they work, before you start spouting psuedo authoritative bullshit.
12.
by weeny 15y ago
You're being rather misleading. If someone solves a problem in a different way from an existing patent (avoids their claims), their new way is not covered by that patent. Patents definitively can't claim "problems"; instead, they can clai

If startups / entrepreneurs who claim to be innovative would work with the patent landscape, rather than irrationally fearing and hating it, they would find that a huge patent portfolio or broad patent like those Yahoo owns are really just

All that prior art will certainly bubble to the surface during the trial process. There is a cottage industry around finding it - kind of like bounty hunting. See articleonepartners.com, a service that lets researchers be rewarded for inv

I am aghast at the disastrous amount of disinformation about patents in this community. Patents are fundamentally and in the libertarian sense of the word, inalienable property rights, that have value, and that can be bought and sold.

Oh boy. This has proved true to me - but from dental surgeons, not physicians. I've gone through 3 dental surgeons who have opened up the gums above my canine teeth, excavated, charged my insurance $1000's and me $100's [the costs of succ

The Rebel LEDs can't be hand soldered or wave soldered. They are reflow soldered. You can do this with a toaster oven.

It is a plastic resin that has been blended to a precise dosage with YAG phosphor. You can buy YAG phosphor easily from wholesalers, for example, phosphortech, a Georgia company, sells a variety of colors of phosphor. However, the trick i

AFAIK the blue LEDs used in these remote phosphor applications is 550 nm "royal blue" monochromatic chip; you can buy these chips on their own, and they are some of the highest energy output chips available on the market.

Philips updates the technology in the Rebel LEDs several times a year. In fact, they have on several occasions demonstrated record-breaking output in this form factor up until earlier this year. The reason that flashlights are updated so m

It's definitely not user serviceable. Indeed, the SMPS circuitry at the base of the bulb is going to fail before the LEDs do, and that stuff is all encapsulated in epoxy.

They aren't blue at all, they are 2700K - and this is a big part of the reason they are 57.8 lm/w. The remote phosphor, while creating a very uniform photometric distribution, reduces the overall light output by filtering the very monochro

Incandescents don't have a "perfect" black-body spectrum, by far. Neither does the sun; both of which have 100 CRI. The CRI metric was also devised around the incandescent lamp to compare them against fluorescent lamps - thus the fact t

Induction lamps are getting big - but most people want to get rid of the mercury vapor arc entirely and go for solid state, that's a big enough advantage that energy efficiency almost doesn't matter. Unfortunately, Switch didn't figure out

The idea is that the yellow phosphor converts a short wavelength blue light from the LED into a longer wavelength yellowish light, called down-converting. This is a special physical property of the phosphor material - not simply a function

So the basic operating principle behind lighting LEDs is the correlation between light output and temperature. As the LED heats up, its light output decreases. If you want a single LED to produce more light, you have to pump more current

The LEDs themselves work excellent at low temperature - but you may have problems with your electronic driver's properties changing at lower temperatures.

it's not exactly a yellow paint, it's a phosphor doping they embedded in the plastic and it's the reason the bulb costs so much. Theirs is very high tech but I don't think it can compete in the long run due to complexity and the costs asso

another comparison to CFLs. the mercury arc in a CFL is struck between two electrodes, and every time the light is switched on the electrodes degrade. So if you are energy conscious and only have the light on a few hours at a time - you w
