CEATEC JAPAN 2004: Day 4

Friday was certainly the low tip of CEATEC JAPAN this year , but expect the convention to be in full golf stroke for its last solar day tomorrow . Yet it will have been today , because our reporting is a day behind . Whoops . Stupid time difference .

Today ’s coverage let in a DVD / MiniDV / grueling drive registrar from JVC , more from the Visible Light Communications Consortium ( as was insure on Day 2 ) , and finally an carrying out of a bizarre Metal Gear - ish engineering science called “ Non - Audible Murmur . ”

This is more of a “ yeah it exist ” character product than anything else . As you’re able to see from the picture , this is not only your standard run - of - the - pulverisation hard drive / DVD recording equipment , it ’s also equipped with a MiniDV tape deck . you’re able to drop your MiniDVs right to the tough drive , edit them , and skewer them out on a videodisc . Amateur porno , anyone ?

In our coverage of Day 2 of this year ’s convention , we speak about using visible visible radiation to transmit datum . I pretend I came off as this being some form of new and marvelous engineering . Well , it ’s still a rattling engineering , but it appears it ’s not as new as I thought . The “ Visible Light Communication Consortium ” held a seminar on Day 4 of CEATEC JAPAN 2004 , where among other things , they let out that the inventor of this technology is none other than respectable older Alexander Graham Bell . dependable old Al conducted tests back in 1880 with what he named the “ Photophone ” – he held the world ’s first ( and I do mean first ) wireless phone call , using visible lighter as his communication culture medium .

We mentioned Professor Nakagawa ( death chair of this “ Visible Light Communications Consortium ” ) in our Day 2 reportage as well – he was back in action mechanism on Day 4 to speak at the seminar . base on tests he conducted back in middle school ( must be the Elmer Leopold Rice ) , Prof. Nakagawa find that the key to fast transmissions for seeable Inner Light - found communications was the speed at which the sluttish source itself would react . Thankfully , lights have come quite a ways from the Clarence Day of Mr. Bell – today ’s light-emitting diode unhorse up “ straight off ” compared to the seconds it would take light-colored bulbs to reach full elucidation back in 1880 . According to Professor Nakagawa , standard ashen LED luminosity currently available on the market have been confirmed to have a transmission focal ratio of around 80Mbps , though this issue does vary more or less depending on the light ’s king . Interestingly enough , the semblance of the LED itself also makes a difference .

Professor Nakagawa highlighted during the seminar that the advantages to seeable light communication theory are a low - priced infrastructure and high-pitched - preciseness system . Specifically speaking , visible light communications are both cheap to make and follow out ; and highly accurate . He could n’t serve but wreak up an exercise of an automate golem using an array of light-emitting diode to gather light information so that they can about “ see ” where they are in a situation . That would be creepy , uncalled-for to say .

Another point Prof. Nakagawa touched on was that this system in all likelihood is n’t well suited for mobile applications . Why ? “ seeable light communication may be possible up to a number of Gb per second , but doing so requires the terminal to be placed only centimeters away from one another . ” At least he ’s being fair with us . He pointed out that for mobile applications , technologies such as wireless LAN and UWB will perhaps be a good alternative , as they do n’t require two devices to be too nigh together .

At the Mitsumi booth , the party was displaying a applied science currently undergoing joint developing with NTT DoCoMo . They ’re calling it an “ inside - the - eubstance mike , ” which apparently utilise a technology called NAM ( “ Non - Audible Murmur ” ) to observe the transmissions of sound through your own body . I half expected to see “ DARPA ” somewhere in this clause , because the Non - hearable Murmur convey only more covert : Non - hearable Murmur recognition can also break up up voiceless sounds inside of your own mouth . I ’m thinking the war machine would be interested in this technology ( if they ’re not researching it already ) , but Japan is all healthcare ; the technology is being developed so that people who are gruesome and can not talk can still pass along .

Or are they ? At CEATEC , Mitsumi display a version of the microphone that pretend as an headphone / microphone for cellular phones . Damn , I SO see that one coming !
