That's important, Beynon says, because, as a result, the system can trigger a camera up to a speed of hundreds of kilohertz, which is, he claimed, beyond the capabilities of any line scan cameras that are currently on the market.
And while Polycom's top-end audio systems broadcast at 22 kilohertz, Medina claims that they still do a lousy job of relaying the true sound of a voice.
That's ground plane reflection, which is fine for low frequency wavelengths like AM radio, (in the range of thousands of kilohertz or less than or right at one megahertz) but not for the higher frequencies that most car remotes work at.
The device, according to its distributor, Moving Sound Technologies, emits a tone set at 17.5 kilohertz, the high end of the hearing range for 13 - to 25-year-olds.
Caveat: Smokers didn't appear to have any more trouble than non-smokers for lower frequencies of 1, 4, or 8 kilohertz.
Nonsmokers began to hear a 12 kilohertz note — about three times as many vibrations per second as the highest note on a standard piano — at about 30 decibels.
And I don't have this device, but I did download the tone, which is a certain kilohertz, and I found it very effective to be a non-confrontational way of, you know, just kind of getting them to leave.
The mosquito works by emitting a pulse at 16-18. 5 kilohertz that switches on and off four times a second for up to 20 minutes.
Microtubules have vibrational resonances in the kilohertz (10 to the third power Hz) for tubulin C-termini, megahertz (10 to the 6th power Hz) for tubulin, and gigahertz (10 to the ninth power Hz) for ordered water in hollow microtubule cores.
At 0.4 kilohertz, the moths startled but settled back down; at 0.6 kilohertz, one moth moved briefly; at all other frequencies, the moths remained unconcerned.
