This driving information is important not only for accident evidence requirements like an airplane’s black box but also in recording driving habits and vehicle wear and tear. In turn, this may identify additional driver training opportunities that can ultimately result in significant financial savings.

When GPS is used for sending vehicle location information to a central office at the end of the day, Bluetooth can be employed to transmit information from the in-vehicle data logger to the driver’s phone and then to the office. Some companies require tachometer information to be sent in at the end of every day no matter where the vehicle is. The ease of using Bluetooth to transmit this information from a data-logger to a phone provides an easy solution for drivers.

In earlier days, patient monitoring in hospitals meant physical connections to equipment and restricted mobility. Advances in less invasive medical procedures have allowed early mobility after an operation. Bluetooth is providing the means for patients to be constantly monitored while they’re freely mobile in a hospital environment.

This accelerates patient recovery. It also provides tangible significant cost savings to the hospital. Once the patient is at home, remote monitoring is Bluetooth-enabled, providing early warning of potential problems if the patient deviates from the expected recovery path, allowing timely intervention by a medical team.

And, many systems already use Bluetooth to permit efficient and seamless operation without operator intervention. In the vending machine market, Bluetooth networks can send audit information back to a headquarters via a server (e.g., remote malfunction warnings). The cost savings of having Bluetooth sending information to the servicing office is significant and enables higher quality of service and reliability.

In the consumer realm, hands-free headsets are the most common Bluetooth application. But increasingly, phones are being networked with Bluetooth into company networks and then on to the Internet via a router.  Bluetooth technology also is changing the way we listen to music, enabling wireless streaming of digital music from almost any audio player.

With wireless control of audio devices, Bluetooth is becoming a necessity for music lovers, with products from Bluetooth stereo transceivers to Bluetooth stereo headphones. Bluetooth stereo audio uses the A2DP (Advanced Audio Distribution Profile) Profile, which replaces wires and cables between speakers and audio output devices.

Playing video games is now much better than the old days when players had to be close to the TV because of controller cord restrictions. Bluetooth also eliminates the situation on work desks with virtually no workspace because of all the cables, cradles, and docking stations needed for connecting cameras, PDAs, and MP3 players. And, cameras now feature Bluetooth, enabling instant image transmission to the nearest color printer or PC, eliminating the tendency to store pictures on cameras for weeks or longer before they are downloaded.
