Saab's Seaeye Falcon DR remotely operated vehicle (ROV) is used in a wide variety of applications, including oil & gas exploration, scientific exploration and data-gathering, and environmental monitoring. Its depth rating is 1,000 m (3,280 ft), and its maximum tether length is 1,100 m (3,608.9 ft) with a 14 mm (0.55 inch) diameter umbilical, although longer options can be achieved with custom umbilicals. It runs on a single-phase, universal auto-sensing, self-selecting input of 100-270V AC at 2.8 kW. The polypropylene chassis, measuring 635 mm x 600 mm x 1,055 mm (25 inch x 23.6 inch x 41.5 inch) is robust and lightweight for buoyancy and lack of corrosion. The robot's launch weight is 100 kg (220.5 lb), payload is up to 15 kg (33 lb), and top speed is more than 3 knots. 6,400 lumens of LED lights with variable density can be tilted to vary intensity, linked to the video camera's 180-degree tilting mechanism. Data and video are transmitted via F2 fiber optics. Powered by five magnetically coupled thruster units with a combined forward thrust of 50 kgf, the Seaeye Falcon DR has a 1:1 power to weight ratio. Standard sensors include auto depth and heading, pitch and roll, and compass. (Source: Saab)
William, I wasn't sure where your (usually) straightforward statements ended and tongue-in-cheek started, either. Re Google, I know what you mean: it's getting harder and harder to find good basic info instead of commercial/sales info. But that result was predicted when the Internet became commercialized.
Ann, it was not completely clear when things turned, so you did a good one on me. About Google; I have had quite a bit of serious frustration when attempting to find information about some product or system and the dumb google search instead turns up a hundred sites that want to sell me one, even if they don't have it and have no concept of what it is. At that point it becomes a first rate time waster.
But on the other topic, while invisibility in the normal sense is a big challenge, being un-noticed is a lot simpler, hence the comment about the missile launching dolphin and such. Consider how easy it would be for you to pass somebody by if a whole crowd were wearing AnnThryft masks. Spotting the real one is a challenge if they all look similar.
Ann, OK, that makes sense. Of course a missile launching fish would be a very interesting creature. Probably we could train a school of dolphin to escort a missile launching robot dolphin, giving it a nearly perfect cover. The main hazard would be poachers. Perhaps DARPA would be interested in that concept, which just popped into my head. I am not at all familiar with the DARPA dolphin program and have never heard of "Freddy the Fish".
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Biomedical engineering is one of the fastest growing engineering fields; from medical devices and pharmaceuticals to more cutting-edge areas like tissue, genetic, and neural engineering, US biomedical engineers (BMEs) boast salaries nearly double the annual mean wage and have faster than average job growth.
