A Plane goes into the sea off kapiti Is , New Zealand . The flight recorders need to be recovered but weather has made the ocean bottom impossible so the international rescue call goes out . A team in Spain have a working prototype to test and Jettrans, a x-military 2 seater fighter jet, is used to transfer a technician and gear to new zealand . The technician has brought cables , software and underwater RF gear which in conjunction with worldwide available computers builds the New VR sonar .
The outline for the system in the dive tender goes as follows Three standard fish finders form a net sensor which via interface cables connect to a PC . This machine processes and packages the data off to a standard gaming machine . (propriatory secret information has been kindly donated for this worthy cause) The gaming machine processes the 3D maths and produces a 2D screen bitmap which is sent to the last machine for 2 channel underwater tranmission . Two pdas (one for each eye) siliconed to a dive mask receive the Rf via dedicated receivers . The pdas are programmed simply buffer data to display because all calculations have been done . The Diver wears two hollow spheres on his head as a sonar vector for the enviroment .
Thankfully the test goes well the diver has a visual representation of the wreckage and the recorders are retrieved catching problems with similar aircraft . The successful technician transmitted the experiment data of the trial to his eagly awaiting team , who were happy with the results .
More enhancements to MurkSee may include more sonor detail , depth, time data and see-thru pdas so VR data is additive to vision . If computers and equipement can be boarded and shrunk then the diver may carry around MurkSee and therefore be boat independent .-- wjt, Oct 11 2003 "Navy agrees to limit sonar systems" http://www.signonsa...7-whales-sonar.html [waugsqueke, Oct 04 2004] Love the 'PDA's siliconed to a dive mask.' Very 'Red Green meets Jaques Cousteau.' Missing the duct tape, though.
Trying to decide if you were shooting for a story with this, or not. If you were, it's pretty awkward yet.-- RayfordSteele, Oct 11 2003 half-Synopsis: High resolution 3D sonar imaging device made with off the shelf consumer grade parts. ?.
Dunno if it'd work. For all I know it might be total nonsense, but I like the synthesis and the cheap factor.
Those PDA's seem a bit close to the diver's eyes to be viewed easily.-- half, Oct 11 2003 Your arms are too long.-- half, Oct 11 2003 Keep your marmots and prairie chickens away from that eagly awaiting team!-- bungston, Oct 11 2003 I hate when a perfectly rational stepping stone logic path is shot down by one glaringly obvious painted polystrene rock that there is no way in hell you want to jump on .
A diver would get tied holding up his arm ,to see the VR , continuously throughout a dive .
Maybe a box structure could distance the Pdas from the divers mask allowing a respectable veiwing distance .-- wjt, Oct 12 2003 The hollow spheres will show up well on the sonar devices, giving an accurate position for the diver. erm...at least thats what I think they're for...
Dive depth would be limited by the crush depth of the spheres. Would the oxygen tank not show up quite well anyway?-- suctionpad, Oct 13 2003 Yes , Two spheres ( metal ? )one slightly bigger on head to show system head direction therefore change VR drawing . Tank no good because diver may be looking in wrong direction .-- wjt, Oct 13 2003 The ocean floor remains either pretty calm or as quite as a tomb depending on the depth. The weather above doesn't affect it except in v. shallow water. However, you could maybe sell this to those bog-snorkeling maniacs.-- squeak, Oct 13 2003 So the recovery divers on a network news item saying that they could only see the distance to their dive watches were telling porkies .-- wjt, Oct 13 2003 OK. How deep are you talking about? Are these human divers or deep sea subs? If you're only talking about relatively shallow water, I'll hush my mouth.-- squeak, Oct 13 2003 Ah! Just detected "eyes" and "head" amongst scary technical words. Human then. Shallow water then. I'll shut up then.-- squeak, Oct 13 2003 [skipper] Thankyou , Idea sunk , not realistic with current sonar , diver interaction . No way around that one is there .-- wjt, Oct 14 2003 True , if , what is that word again, cetacean's have sonar that doesn't effect the enviroment , maybe the idea can refloat .-- wjt, Oct 14 2003 random, halfbakery
