We've got an RF warning on the camera, which means that the signal's not actually getting onto the tape. It's usually a head clog.

摄像机出现电磁射频的警告，就是说信号没法传入录像。一般是磁头堵塞。

RF technology is what most other wearable LED companies use too, like Xylobands, who do everything from Eurovision to corporate events.

大多数其可穿戴式 LED 公司也在使用射频技术，比如 Xylobands，从欧洲歌唱大赛（Eurovision）到企业活动，们的产品无所不有。

But whether it's Bluetooth, RF or infrared, the experience of these wearable pieces of technology are only getting more detailed to make every fan feel like part of the show.

但无论是蓝牙、射频还是红外，这些可穿戴技术的体验只会变得越来越细致，让每个粉丝觉得自己是这场表演的一部。

When fans went to their seats at Madison Square Garden, they found one of these RF wristbands waiting for them, each one pre-programmed to be a part of a different group.

当粉丝们来到麦迪逊广场花园的座位上时，们发现座位上会有一个射频在等着们，每个被预先设定为不同组的一部。

Let's start off with the simplest, RF wristbands, that receive a radio frequency communicating the precise timing and colors for each band.

让我们从最简单的射频开始，它接收一个无线电频率，传达每个的精确时间和颜色。

As cell phones make and take calls, they emit low-level radio-frequency (RF) radiation.

当手机拨打和接听电话时，它们会发出低水平的射频 (RF) 辐射。

They call this Panasonic RF and I think in English it's microcurrent.

们称其为 Panasonic RF，我认为在英语中是微电流。

So could it be an RF signal that's switching it?

那会不会是射频信号在切换它？

RF generator, spectrum analyzer, logic analyzer, another logic analyzer.

射频发生器、频谱析仪、逻辑析仪、另一个逻辑析仪。

Yes, from what I saw RF or maybe a couple of uses whenever you got tired of carrying it around Okay, and probably I would guess having formerly smoked a pipe at two separate times in my life, right?

是的，从我看到的情况来看， RF或者可能只是偶使用， 当你厌倦了随身携它。好的，我想猜一下， 我以前在生命中的两个不同时间段抽过烟斗，对吧？

And if you add some pneumatic pistons connected to a mini pressure intake controlled by a solenoid valve triggered by an RF remote, then you could shoot the ball normally.

如果再加上一些气动活塞， 这些活塞与微型压力进气口相连， 并由电磁阀控制， 而电磁阀则通过无线遥控触发，那么你就能正常投篮了。

That is becoming extremely popular on social media at the moment since we saw RF Kennedy using it on an airplane.

由于我们目睹了RF·肯尼迪在飞机上使用它，这目前在社交媒体上变得极其流行。

I got to ask you, this is a different category, but I got to get this in EMF and RF.

我得问你一下，这个属于不同的类别，但我要把这个内容放到电磁场和射频中。

And this is something actually that has been used with RF accelerators, I think, back in the 50s.

实际上，这正是从20世纪50年代起就已应用于射频加速器的技术。

And the RF cavity gives it a position-dependent kick.

而射频腔则根据粒子的位置给予其相应的加速。

Oh, RF Retta that continued on.

哦，RF Retta 还在继续。

Using your cell phone's speaker or connecting a wired headset--- while keeping the handset away from your body--- drastically reduces RF exposure.

使用手机的扬声器或连接有线耳机——同时让听筒远离您的身体——可以大大减少 RF 暴露。

When it's energy sorted, we then send it to the RF cavity.

当能量排序完成后，我们再将其发送到射频腔体。

But the good news is that there are easy ways for those concerned about RF radiation to cut down on exposure.

但好消息是，对于那些担心射频辐射的人来说，有一些简单的方法可以减少暴露。

Right now, many particle accelerators are known as radiofrequency, or RF accelerators, which are part of some famous experiments you've probably heard of, such as the Large Hadron Collider.

目前， 许多粒子加速器被称为射频（RF）加速器，它们是一些著名实验的组成部， 你可能听说过，比如大型强子对撞机。
