One-chip Bluetooth solution powers hands-free kit
The Bluetooth Voice Box from Uniwill Computer Corp is Bluetooth-enabled by CSR's BlueCore single-chip Bluetooth solution.
Three other tier-one cellular OEMs, existing CSR customers, use BlueCore for stereo headsets designed for use with mobile phones.
The digital signal processing (DSP) architecture built into CSR's BlueCore technology means CSR offers the only Bluetooth silicon with native support for MP3.
This results in better design functionality and up to twice the battery life.

Bluetooth chip comes with performance guarantee
Cambridge Silicon Radio guarantees that its second-generation single-chip Bluetooth solution, BlueCore2-External, will meet or exceed the Bluetooth specification between -40 and +85C.
CSR's DSP inside the BlueCore IC is highly optimised to run audio codecs including the basic SBC (sub-band codec).
More importantly however, CSR's DSP architecture has the processor throughput to support MP3, AAC and other proprietary codecs, with power consumption figures low enough for battery powered applications.
Competing solutions only offer support for SBC and consume twice as much power as CSR's 95mW, making them unsuitable for such applications.
CSR's BlueCore is the world's first and only Bluetooth silicon to support and integrate MP3 and other highly compressive codecs.
Because of this, customers for CSR's stereo headphones or headsets benefit from enhanced audio quality and improved wireless operating range compared with those using first generation designs that support only SBC.
John Hodgson, CEO of CSR commented: "There are already tens of millions of people who own iPods or other MP3 players and these people will now be able to benefit from much more convenient wireless headphones".
Hodgson continued: "CSR is the leader in each and every Bluetooth market sector - that includes both mono and stereo headsets".
"In 2004, CSR's BlueCore was designed into 85% of Bluetooth headsets".
Glenn Collinson, cofounder and Sales Director added: "CSR offers customers native support for MP3 and twice the battery life offered by the competition".
"It is clear why headset makers continue to choose to design in BlueCore".
Only Bluetooth headsets designed using CSR's BlueCore can wirelessly connect to a Bluetooth mobile phone and a music player simultaneously.
When the user receives a phone call the device will automatically mute the sound and connect to the mobile phone.
At the end of the call the original music connection will resume automatically.
Only CSR's BlueCore can reliably support multiple simultaneous connections meaning that headsets designed using other silicon cannot successfully support this feature.
