Cyclists' GPS system uses music to guide you +VIDEO |
It's called 'Oh Music Where Art Thou' and the designers claim it makes navigation fun |

Oh Music Where Art Thou.jpg |
A group of students from the Netherlands is working on a development that combines existing GPS data and the music on a mobile device to steer you towards your destination without onscreen arrows or voice commands. |
The four User System Interaction trainees from Eindhoven University of Technology have designed their variation of a GPS navigation system in combination with a small portable computer, in this case an Android-based smart phone, along with a pair of headphones to help cyclists navigate without distraction from the road... |
The system named 'Oh Music Where Art Thou?' relies on the human brain's ability to detect tiny differences in audio balance between the left and right ears and the students have worked on artificially altering the perceived direction of this stereo image audio to guide the user to a predefined location. |
"At the moment the prototype only works for predetermined locations," the team's Daniel Tetteroo told the technology website Gizmag. "However, we are busy developing it into a full application that supports navigation to basically any place in the world. The finished application will be available soon through the Andro... |
At we're aware that the cycling world is strongly divided on the issue of music-on-the-move, many arguing with some justification that environmental sound is not only a large part of the pleasure of cycling but also a potential life-saver amongst the hurly burly of city traffic or even (especially!) out in the lanes. W... |

Nice idea but gives absolutely no consideration to hearing impaired riders. |
I have tinnitus in my left ear that reduces my hearing at higher frequencies by 30dB SPL (5 times quieter than my right ear). I cannot wear headphones for any length of time. |
A friend of mine has an issue with the bones in his ears that they are disintegrating. (he has had surgery to replace the ones in his right ear) and his hearing is greatly impaired in his left. |
Also, this encourages people to wear headphones when riding which reduces their awareness of their surroundings. |

The return of Silvio Berlusconi |
Mamma mia |
Italians may come to regret electing Silvio Berlusconi once again |

Readers' comments |
While the Economist has not always been right on everything, reading this article reminds me why I've been a subscriber of the Economist for the last 25 years. Belrusconi's picture in this article, depicts a facial expression and demeanor, that speaks louder than the article itself. Now, the onus is Belrusconi's to pro... |
Serenissimo, Maurizio |
if you read the Economist that should probably mean that you are actively looking for grounded and objective opinions. Honestly, things that this newspaper has been quite successful in delivering. So, what have you read in the past years? Just the advertisements? You guys don't get it. The man is simply unfit! He shoul... |
I don't believe that The Economist or any one else is implying that Italians who voted for Berlusconi are stupid. Unwise, scared, and cowards perhaps, would be more appropriate nouns. I put the name of Barak Obama , yes I know.., on the voting ballots after crossing all the other names, because none of the politicians ... |
Dear Oldwisdom,Do you have a name to suggest in place of Berlusconi that would be good for Italy?We'd appreciate to know your ideas... |
A wise man by the name of Indro Montanelli, definitely not left oriented, once said that the Italians needed to be vaccinated against Berlusconi, therefore needed to try him once before deciding to cross him out. Sadly, Montanelli underestimated the ability of Berlusconi to dupe the crowds with his ill sense of humour ... |
To those that voted him, on the basis of having no viable alternative, here is a thought on just one case that reveals the mentality of your man: are you prepared to put more public money into Alitalia, a company that failed despite huge public subsidies and is by all means out of the market? Just consider Berlusconi's... |
Even if I did not vote for Berlusconi, I agree with Maurizio! |
Italians are not stupid. |
Simply, they have fear and don't risk enough: it's a pity, but it's perfectly rational. |
Supply-side reforms are necessary but menace all insiders: professionals, for-life full-time workers, olygopolist entrepreneurs like Berlusconi himself! |
So many people prefer stay relatively poor but secure!! |
And stop, please, stop, stop stop to offend dozens of millions of people simply for having a different opinion from yours! |
You don't seem living in a democratic world!!!! |
Maurizio, I'm one of the millions Italian mafiosi that voted for Berlusconi as well...What stupid people we must be! |
Dear SirsI am one of those millions of people that voted for Silvio Berlusconi, blinded by his TV network and by his grip on Italy's media. Given that I am completely stupid and, together with some other millions of Italian mafiosi, I have no clear knowledge of my interests, I will gone on reading your kind magazine an... |
I'm not sure if the comments received so far come from real Italian people, or just people that know about Italy only from the Economist.You guys don't like Berlusconi and I might agree with that, but what real alternative did we have?Veltroni? Wasn't he a sponsor of the Prodi government?I think the real problem of Ita... |
for stillme - in the last 50 years (13 competitions) 7 went to South America and 6 to Western Europe. Argentina and Italy both won twice. :-|Is football an opium of the masses, an escape from the chill winds of competition?Has South America had the same corruption issues in professional football as Italy?For Italy - he... |

Rather that make reforms, Berlusconi will ruin the Italian financial situation by lowering taxes without amministration expenditures decrease and structural expenditures reforms. The italian public debt will blow again...How it is possible that the Italian left wing parties have always such a work to do in equilibratei... |
I am so glad that you have stuck to your gun and you have hit the nail on the head in your analysis of Silvio Berlusconi's fantastic electoral success.Mr Berlusconi keeps on repeating that he is a liberal but he did not carry out any major liberalisations during his previous full term government when he also had a larg... |
Italians who supported Berlusconi were clearly upset by foreign news papers like the Economist's interference into Italians domestic politics. Accusing this news paper and others of communism, arrogance, and lack of understanding of Italians politics and Italians. Ironically these sane Italians fail to understand that ... |
Ok, now that this clown is back in power, everyone should give him a chance to do something meaningful. The first thing would be to let Alitalia collapse and allowed another European carrier set up hubs at Milan-Malpensa or Rome-Fiumicino. Italy really needs a Margaret Thatcher (someone con le palle quadrate) to take o... |

I really cannot believe this jackass is back. I feel like the rest of the world felt when W was re-elected in 2004-as in I want to ask an actual Berlusconi voter what the hell they're thinking. |

Hydra-70 Rocket System |
Integration Information |
HYDRA-70 Rockets are free flight rockets which mate either unitary or cargo warheads with |
the MK 66 Rocket Motor. The MK 66 motors use a longer motor tube (than the MK 40/MK 4) |
fins are of a spring loaded, wrap-around design and are attached around the circumference of the |
single nozzle. The propellant grain is longer and of a different formation than for the MK 40/MK |
4, however, the stabilizing rod and igniter are essentially the same design. The MK 66 motors |
have a substantially higher thrust, 1335 lbs, and a longer range. The current generation of the MK |
66 in use by U.S. Armed Services are the MK 66 MOD 3 for the Army and the MK 66 MOD 2 |
The RF filter is mounted onto the igniter can and allows the aircraft’s direct current firing pulse to |
May 1987 documents the HERO suitability of the MK 66 MOD 3 motor. A brass EMR shield is |

M151 Warhead |
M229 Warhead |
Both the M151 and M229 use the M423 Fuze, making them High Explosive Point Detonating |
(HEPD) warheads. The M151 uses 2.3 pounds of composition B-4 High Explosive. The 10 |
pound warhead gains lethality from the nose section which is fabricated using nodular, pearlitic |
malleable, or ferritic malleable cast iron. The 17 pound M229 uses 4.8 pounds of composition B- |
4 High Explosive. The performance of the M229 is roughly a 50 percent increase in lethal area |
over the M151. Temperature limits for storage and firing the M151 and M229 are -65 oF to +150 |
F (-53.35 oC to +64.9 oC). |
The M423 Fuze consists of four major assemblies: firing pin and body assembly; fuze body; |
safe and arming (S&A) device; and the booster assembly. The S&A device consists of a rotor |
housing assembly and unbalanced rotor assembly, an escapement assembly and set-back weight. |
The unbalanced rotor assembly houses the primer and detonator and is maintained in the unarmed |
(out-of-line) position. When the rocket motor is fired, sustained acceleration permits the set-back |
(inertial mass) weight to move rearward, releasing the unbalanced rotor, which in rotating drives |
the escapement and gear assembly to the armed position. The rotor reaches the armed (in line) |
position when the rocket has traveled 43 to 93 meters and then is locked into the armed position |
by a spring-loaded pin. The rotor will return to the unarmed position if the minimum rocket |
