Legalize it? Colo. considers one-ear, in-car headsets

Colorado could become more friendly for hands-free talking under a proposed tweak to state traffic law.

The bill would specifically legalize the use of one-ear headsets by drivers, if connected to a mobile phone.

Current Colorado law bans the use of "earphones" behind the wheel, which is defined as "any headset, radio, tape player, or other similar device which provides the listener with radio programs, music, or other recorded information through a device attached to the head and which covers all of or a portion of the ears."

While that definition does not specifically cover phone calls, it leaves enough ambiguity in law that a small group of House Democrats wants to clear it up.

HB 1207 would add an exception to the definition of "earphones" in state law, to exempt: "a headset that only covers all or a 10 portion of one ear and that is connected to a wireless, hand-held telephone."

The house transportation committee unanimously passed the bill on Thursday morning.

Colorado law does not specifically address the issue of hands-free phone use versus calls made with a handset held to the driver's head. Under Colorado law, adults are allowed to engage in phone calls behind the wheel, while minors are not.

Numerous scientific studies conclude that hands-free talking is not significantly safer for drivers than talking with the phone held to the ear.

More important than tying up a hand is the fact that engaging in a phone conversation ties up the brain, splitting a driver's attention between the call and the road and using a significant chunk of the brains cognitive capacity when it would be better applied to the task of driving.

In 2013, Colorado police officers reported that 1,311 crashes were caused at least in part by distraction due to a cell phone, roughly the same number caused by distractions from passengers actually in the cars that crashed.

That statistic does not differentiate between the use of a phone for talking versus texting. Texting behind the wheel is illegal for drivers of all ages in Colorado.

How Does Spy Earpiece Work?

The spy earpiece is a gadget of the future that facilitates our lives. With the spy earpiece invisible communication is performed in most troublesome situations when cover assistance is necessary.

The main feature of the spy earpiece is its complete invisibility. First of all, the spy earpiece goes in beige hue that is very close to skin color. So when you insert it into the ear, nobody can even notice it. Besides, the spy earpiece can boast of super tiny dimensions that ensure absolute invisibility of the gadget when it is in the ear.



The good news is the spy earpiece is available on the market in diverse gadget sets. The most popular of them are Bluetooth Set, Watch Set, MP3 Set and Glasses Set. Each one of the sets listed above has an in-built transmitter and a microphone (in the loop for Bluetooth and MP3, in the bow of the glasses and on the reverse side of the watch). Thanks to the transmitter, the gadget gets connected to the cell phone. And thanks to the sensitive microphone your partner will hear your every word even if you whisper. So, as you can see the spy earpiece set consists of the transmitter with an embedded microphone and a spy earpiece with a battery.

It is pretty easy to use the spy earpiece. What you have to do is the following sequence of steps:

· Put the transmitter. If you use the Bluetooth or MP3 spy earpiece set, you are supposed to put on the loop round your neck. Make sure that the loop is properly hidden under your clothes. For Spy earpiece Watch set you put on the watch on your wrist, and for Spy earpiece Glasses set â€" just use it like ordinary glasses.

· Insert the battery into the spy earpiece. Every set comes with a detailed guidance for that, so don’t be afraid of doing something wrong. Anyway, if the quality of sound is unsatisfactory, try to change the position of the battery.

· Put the spy earpiece into the ear. Here you should remember that you always have to clean ear canals beforehand. Otherwise, the spy earpiece filter will choke up with earwax and sound will deteriorate significantly. In the worst case the spy earpiece will fail to work.

· Make a call. When you are ready with preparations just make a call and put the cell phone into your pocket. You won’t need it any more. Now the covert communication is established. You can hear what your partner is saying.

· Pull the spy earpiece out. This is very easy to do thanks to a special ejection cord every spy earpiece has. You can see it in any picture.

· Take out the battery. Be careful about pulling out the battery. You have to do it only with the help of a paper pin so that not to damage the spy earpiece. In case you won’t take it out, the battery will discharge.

With the help of the spy earpiece you will never feel embarrassed and confused when speaking in public, writing a test, having an interview or taking an exam. The spy earpiece will help you to feel confident and be successful.

What is an Acoustic Transducer?

From Wisegeek.com “What is an Acoustic Transducer?” (27 January 2010)

An acoustic transducer is an electrical device that coverts sound wave vibrations into mechanical or electrical energy. They have various practical applications, including sound recording and sound playback. A specialized model, called an ultrasonic acoustic transducer, can be used to measure distance to, as well as the mass of, an object.

Common types of acoustic transducers used in sound recording include microphones, earphones, and guitar pickups. These create electrical energy when moving parts inside the transducer, such as electrical plates or ribbons, are exposed to sound vibrations. The electrical energy produced inside the transducer is sent first to an amplifier.

The amplifier then sends this energy to its final destination, usually a loudspeaker or recording device. The loudspeaker reproduces the sound at a level that the human ear can hear. A recording device will retain the electrical signal information. The recorder will send the stored signal to a loudspeaker during playback.

An ultrasonic acoustic transducer can be used to measure distance or the mass of an object. The most common type is the piezoelectric acoustic transducer. These include a piezoelectric ceramic element that creates and distributes ultrasonic sound waves.

Sound waves travel to an object from a piezoelectric transducer through material called a couplant. The couplant is usually water. Sound waves bounce off the object and return to the transducer in the form of an echo. The time it takes for these echoes to return to the transducer is used to calculate the distance to the object.

Underwater sound navigation and ranging (SONAR) is a common use of an ultrasonic acoustic transducer. SONAR uses directional beams of sound waves. This enables the SONAR operator to determine the direction and distance to an object.

SONAR systems can be active or passive. An active system sends out sound waves and listens for echoes. A passive system listens for noises made by ships, fish, and landmasses.

An electromagnetic acoustic transducer (EMAT) is another form of ultrasonic transducer. Instead of a ceramic element, an electro magnet is the main component of an EMAT. This is a type of non-contact, or non-destructive transducer. Unlike piezoelectric transducers, EMATs do not need a couplant to carry sound waves. Instead, two electromagnetic fields are generated to disburse ultrasonic waves.

EMATs can easily be used almost anywhere since no liquid is needed. For example, EMATs can be used to check for flaws in underground pipes. A downside to EMATs, compared to piezoelectric transducers, is that EMATs create weaker sound fields.
