So, that's a finished gear.

And so what we get then from the pop up satellite tag is we get away from having to have a human interaction to recapture the tag.

He's also considered the greatest wave finder in the world.

That little gear there switches back and forth to change direction.

It is the ratio of the angle of action to the angular pitch.

Wire wheels are used on most bicycles and still used on many motorcycles.

Of course you can. You saw that they found SARS using their Chinese web crawler a full six weeks before they found it using their English web crawler.

Some time later, the team members lock Radio inside the gear shed, tied up.

But that's about half the size of the biggest tuna we've ever tagged.

That satellite tag will now have your shark phone home and send in a message.

And as he did so, his customer noticed that on the back side of the balance wheel was an engraving, were words.

It's really tough to get up close and personal with a mako shark and try to put a tag on it.

In this case, what we're going to do is put a pop up satellite archival tag on the tuna.

And we'll place an acoustic tag that says, OMSHARK 10165, or something like that, acoustically with a ping.

It's a free swimming shark with a satellite tag jumping after salmon, sending home its data.

The differential analyser, a mechanical analog computer designed to solve differential equations by integration, used wheel and disc mechanisms to perform the integration.

Arc of action, Qt The arc of the pitch circle through which a tooth profile moves from the beginning to the end of contact with a mating profile.

On 17 May 1902, archaeologist Valerios Stais was examining the finds and noticed that one of the pieces of rock had a gear wheel embedded in it.

In this case, at trespass points, allowing people to go through because your little tracker device said they were okay, actually cost lives.

In more recent applications, hydrogen is used pure or mixed with nitrogen (sometimes called forming gas) as a tracer gas for minute leak detection.

And from that mucus, we can get gene profiles, we can get information on gender, checking the pop up tag one more time, and then it's out in the ocean.

There are 12 pairs of 50 1 reductions, so that means that the final speed of that gear on the end is so slow that it would take two trillion years to turn once.

And then we'll put on a satellite tag that will give us the long distance journeys with the light based geolocation algorithms solved on the computer that's on the fish.

Randi then replayed the video, but with some of the sound dubbed in that he and his investigating team captured during the event using a radio scanner and recorder.

The patient receives an injection of a radio tracer that's taken up by rapidly proliferating tumor cells, but not by normal cells, and this is the key difference from mammography.

And then with a lot of effort, after tagging, putting in the computer, making sure the stalk is sticking out so it senses the environment, we send this fish back into the sea.

And from our data that gets collected, when that tag comes back, because a fisher returns it for a thousand dollar reward, we can get tracks beneath the sea for up to five years now, on a backboned animal.

The device became famous for its use of a differential gear, previously believed to have been invented in the 16th century AD, and the miniaturization and complexity of its parts, comparable to a clock made in the 18th century.

And then imagine being Bruce Mate's team from OSU, getting up close to a blue whale and fixing a tag on the blue whale that stays, an engineering challenge we've yet to really overcome.

The device became famous for its use of a differential gear, previously believed to have been invented in the 16th century, and the miniaturization and complexity of its parts, comparable to a clock made in the 18th century.

This tag rides on the tuna, senses the environment around the tuna and actually will come off the fish, detach, float to the surface and send back to Earth orbiting satellites position data estimated by math on the tag, pressure data and temperature data.
