  1. Re:O RLY? on Why Bad Jobs (or No Jobs) Happen To Good Workers · · Score: 1

    Well, the role of greedy union in killing American jobs is well known. A secondary effect is the fact that laid off union workers are 'tainted' by the risk of recall.
    If you hire a laid off UAW worker, train him, etc, then he gets a recall - he is gone, no notice in many cases as a recall is next day quite often. I check references, and I find no need to hire an ex-union man when there are other better people in line. This is managements fault by giving in too easily under the impression they can just increase the sale price of their cars. This thinking has killed 90% of the UAW jobs over the years. Now the unions have killed most cities, via high wages and pensions that we the tax payers will no longer pay. Cities will are going broke and still the unions will not yield. This is complex for here, but the whole state-city-school system in many states need total destruction and rebuilding with none of the former workers hired (why hire them - they will just do it again)

    Supercavitating is super noisy and very detectable by underwater ears.
    The supercavitating transition layer reflects sound very well = also detectable.
    at 300 to 500 miles per hour the immediacy compensates for the noise which makes it hard to localize, but you sure know it was around.

  5. Re:Regulated medical device on Ask Slashdot: Why Are Hearing Aids So Expensive? · · Score: 1

    You misread me. A duplexer permits a radio transmitter and receiver to use the same antenna and transmit and receive at the same time. Duplexers in cell phone systems have multiple transmitters and receivers sharing the same antenna. By careful tuning of pass and reject cavities and tuned lengths of coaxial cable you find the best solution. This solution is iterative = tune and try. In a hearing aid you have amplification and conduction of the sound to the person by various means. Feedback must be avoided by active and passive means, which leads to limitations in very deaf people.
    Use of ear/head structure to provide stereo directionality is present, but the outer ear structure is lacking on their input microphones, I am not sure how they gather this for best results.
    Yes, modern hearing aids have filters to suit the ambient sound environment, and can be customised for job use and these aspects which limit sensitivity can be turned off when in a very quiet area.
    It is easy for people with $$ or medical plans to say the result is priceless, but if you do not have the price....what then? Large numbers of people are priced out of this market by avaricious companies who have a local monopoly because the barrier to entry is high. It might cost you $5 million to perfect the design. I say, plan for the sale of 5 million units and the design cost is only $1 each. These units are quite low in cost, since they have only a single chip. battery tech and ribust hermetic sealing and sound tube transmission are mature technology, so Bill Gates could create a hearing aid to sell for $25 each - if he had the mind to do it, and let an ecosystem emerge to fit these to people with self test setups in Walmarts. The doctors lobby would hate the killing of their cash cow, and will fight back, of course.

    Yes, the chart of sensitivity versus frequency can be fully automatic, but it is usually done manually so the fee can be maxed. I would like to see a machine, like blood pressure in Walmart where you wear headphones and respond to various sounds at various frequencies at lower and lower intensities until they have mapped your profile. It should take 2 minutes or so, depending on the number of data points wanted, with more data = more time = better profile.
    Like the BP machines, the next step is to a doctor, but with hearing profile chart from the machine. you would be able to send that profile to a number of makers and get quotes. Since this is fully external, it should be OK, but some specialists will fight tooth and nail to "protect the public" to outlaw it. In 1950 most highrises had an elevator operator, you entered, told him your floor, and he pushed that button for you. There were endless strikes by the elevator operators union who said thousands would die (LOL) unless we keep our jobs and by the way, we want more $$.

    Familiar with duplexer tuning, however a hearing aid is mono-directional, and as solidraven (1633185) says, determining the gain versus frequency profile should be quick. Frequencies that have gone fully deaf - no cochlear hairs left, will probably not be compensatable with an external device, we can directly stimulate the nerves with a cochlear implant, after which the person learns to hear anew. Here is a simple youtube about it http://www.youtube.com/watch?v=SmNpP2fr57A, the comments are also of interest. This search is also useful http://tinyurl.com/cq8bz3w.

    It is my understanding that you can buy the programmable chip that is a complete processor heart of a hearing aid from many makers. Here is another search on that topic.

    If a persons hearing in each ear is charted, frequency versus sensitivity you fine a lot of variation in people with hearing loss at various frequencies caused by various legal and not legal drugs, loud music, impulse noise from Guns of jets etc. The hearing aid is then programmed to boost/cut various frequencies to get as close as possible to the natural ear with no deficiencies. They have built in equalization. The better the resolution of this equalization and the better the job the audiologists do and the better hearing aid purchased = best results. The hearing aid itself has a base cost of about $50, plus fees to program each one, test with the person in a quiet room, fit to the ear drum shape etc, all adds cost. Low power, more efficient units cost more = last longer on smaller battery

    That said, there are many ripoffs out there, and many locked up distribution channels by people who want to sell a $50 item for $2000. Hearing loss forums can help, but they get a lot of manufacturers shills in there, takes a while to know the crooks.

  9. Re:Ummm. on Organics Can't Match Conventional Farm Yields · · Score: 1

    Since organic labels are cheap to buy and there is no enforcement I have heard that a number of people have learned to buy badly shaped vegetables and sell them as organic - thus getting a premium price for cheaper goods. The consumer is non the wiser, poorer, but happier?

    I wonder how widespread this is? In the absence of a predator, a new life form can prosper. I see regulators as the predators would make sure organic food was in fact grown to certain rules and the fakers are their legal prey.

    I am a retired teacher (2002) and the union brass has done everything they could to impede computerization. All excess money has been drained into salaries, and nothing into smartening up the teaching staff so they know a hole in the ground from a nether aperture. This sounds bad, and it is. The structure of teaching salaries does not allow for competence in IT or any hard sciences. Teachers start with a teaching certificate at low wages and over 10-15 years advance in grade and in extra courses taken to a high wage. the start is about $35,000 in Toronto and the top end is about $83,000, plus generous benefits and a short work year. The usual teacher starter is an arts graduate of some king plus a year in teachers college
      Engineers and good IT people start at $60-70,000, so none enter teaching at the bottom. The union will not allow anything else.
    Union greed conquers all.

    Rome allowed lots of religions. As time went by the faithful came to be an armable resource for use in local conquests as well as resiting local conquests by others. Religions came to see that they must supervise their flocks closely. Catholics were like this back in the old days. Reformation allowed for fragmentation and large numbers broke away. In the UK under 5% go to church, same in Canada. Scientology and Islam go to great lengths to keep their adherents - frequent prayer in groups, punishment of breakaways, etc. They both need a reformation. No-one seriously thinks of scientology as a religion - it is a racket. I happen to feel all religion is a racket.
