While not taking a personal position on this matter, I would ask you to read this and see if it influences your opinion of Ms. Clinton's qualification for the office of POTUS:
I guess you haven't heard of Positive Train Control: http://en.wikipedia.org/wiki/P...
On the basis of trusting that the AC truly is one of the authors (of the scholarly paper), I want to thank you for these clarifications and suggest to all to mod that post up. It definitely is better than score: 1, which is its current value at the time of my writing.
110 dB of SI cancellation is beyond impressive - it is approaching magical!
On the face of it, this capability will double capacity of any RF channel for which it will work. AC claims this can be made to work on channel bandwidths exceeding 20 MHz, therefore making it useful for WiFi.
But I think there are other advantages. If a traditional system uses FDD (frequency division duplex) to achieve duplex (simultaneous transmit and receive) operation, then this new technology reduces by half any discrete RF/IF filter hardware needed to reject out-of-channel energy. That will help make the electronics simpler and less expensive. For FDD, the cost of the filters goes up as the two channels (transmit and receive) get closer together (the closer TX is to RX, the steeper the filters have to be to achieve adequate rejection). With this all-silicon approach, the most you need is bandpass filtering for the ONE channel you are using. Big win!
But then maybe I am exposing my dinosaur-like thinking in even bringing up discrete RF filter components. A recent announcement at Mobile World Congress touted a silicon-only radio technology that didn't appear to need any discrete filtering at all.
Also my (dinosaur-vintage) thinking about cellular base stations is that they generally operate in the +40 to +50 dBm range (out of the PA, prior to duplexers, etc. and not considering antenna gain), which implies another 20-30 dB isolation is required (vis-a-vis the AC's claim of 110 dB) to achieve the same isolation one would need in a cellular system. But then I'm not considering antenna gain which seems (without thinking about it too hard) to potentially improve the isolation if separate TX and RX antennae are used at the base station. Then again, I'm thinking macrocells here. But for a single channel duplex RF technology to be deployable in cellular, I think one would need to cover the macrocell case - in any case.
So back to you, what are you going to do when oil runs out in just a century or so?
I will roll over in my grave, ok?
Next to that, we need a system of converting CO2 from the air into a usable fuel, ideally propane, because propane is not a greenhouse gas and inert.
Really? My reading is that the equation for propane combustion is: C3H8 + 5O2 = 3CO2 + 4H20
Maybe propane produces less CO2, pound for pound, than say, coal. (I don't actually know, and don't care to look it up.) But it certainly produces CO2 when burned.
Oh, and anyone who's ever cooked on a propane grill, or used a propane torch, will attest to its distinct non-inertness...
Fire Ants FTW!
That is one of my favorite analogies, and I've never before heard anyone use it besides myself. I grew up in Florida, where I used to kick the tops off of ant hills all summer long. Free entertainment for out-of-school kiddies.
Just be sure to take a few steps back after kicking...
Would you please provide some kind of citations to historical documents to support your assertion?
Unfortunately, a small, aggressive, well-funded minority can always subvert the democratic process.
If by this, you are obliquely referring to the NRA (as the aggressive, well-funded minority), you might take note that right now in Washington State, billionaires are out-spending the NRA (and pro-gun overall) by a ratio of 7 to 1 on an initiative to expand background checks. Well, at least that is what they are calling it. It's a whole lot more than "simply" expanding background checks, but I digress...
Said billionaires include:
Bill and Melinda Gates, Paul Allen, Steve Ballmer (gotta love all that Microsoft money slushing around)
and Michael Bloomberg.
I particularly thrilled at how Ralph Fascitelli of Washington Ceasefire recently invoked the imprimatur of Dan Satterburg (King County prosecutor) as a supporter of I-594, while not mentioning the rest of the state (King county is a little over a quarter of the state's population). This was, of course, to a Seattle audience (who would care about the rest of Washington's population - how?).
Wi-Fi is not a wireless communications standard. IEEE 802.11 is the wireless communications standard. Wi-Fi is a registered trademark of the Wi-Fi Alliance - and industry trade organization. They do publish interoperability agreements and offer "certification" (required to use their trademarks on products), but these should not be confused with the IEEE wireless communications standard.
(rant done - going back to reading now...)
I'd like to take a moment to memorialize a pioneer in this pursuit that probably none of you ever heard of. The name is Jim Lovette. Jim worked with me at Apple in the early 90's. He was a heart-and-soul devotee to the democratization of RF bandwidth for high speed data communications. With Jim's leadership, Apple drafted a petition to the FCC, known as Data-PCS. This was a proposal to allocate spectrum in the U.S. exclusively for use in data communications (as opposed to "voice only" which was the vogue at the time). The Data-PCS petition caused a lot of excitement, but did not result in anything earthshaking as an outcome. Still it started a movement of which this latest step is a grand one in the pursuit of "computing devices talking to each other" being equally important to "people talking to each other." Jim (and our team) were also early promoters of wireless LAN, which we all know today as WiFi. The IEEE 802.11 committee had just formed. Apple's early foray into wireless LAN preceded the availability of IEEE 802.11 (aka WiFi) products, and never made it to market. Apple chose instead to introduce their first wireless LAN products as 802.11b (11 Mbit/sec) WiFi. And over 20 years later, look what it has become?
Jim passed away in 2002, leaving us with a legacy of which few outside the cloistered Wireless LAN industry would even know he contributed so much. Thank you, Jim.
Moore's Law is an expression of exponential growth. All we are seeing is the logical conclusion of applying exponential growth expectations to a real world finite resource (i.e. the fact that atoms have an essential finite size). See Wheat and Chessboard problem for reference.
What you are describing is known as TLER or "Time Limited Error Recovery" (the Western Digital name for it, at least). See TLER
R'd the F.A. I don't see anywhere it says that a design patent is not a patent.
OTOH, there is USPTO which disagrees with you when they say:
"A patent is an intellectual property right granted by the Government of the United States of America to an inventor “to exclude others from making, using, offering for sale, or selling the invention throughout the United States or importing the invention into the United States” for a limited time in exchange for public disclosure of the invention when the patent is granted.
There are three types of patents. Utility patents may be granted to anyone who invents or discovers any new and useful process, machine, article of manufacture, or composition of matter, or any new and useful improvement thereof.
Note the three types: design, utility, and plant. Design is most assuredly a type of patent.
I built one of these as well, except I added an extension arm off to the side and mounted the control panel on the extension. Otherwise, same outcome.
Now, if only I would use it...
Hydrogen will win the end, we just don't know how yet...
Wow - that is a "faith based" point of view if ever I've seen one.
