SoundOfMotion Releases Fork Mounted 1-degree Precision Bluetooth Bicycle Sensor

SoundOfMotion Releases Fork Mounted 1-degree Precision Bluetooth Bicycle Sensor










Vancouver, Canada (PRWEB) November 13, 2009

SoundOfMotion is releasing version 3.5 of it's high precision VeloComputer bluetooth bicycle sensor. This new version achieves 1-degree precision during wheel rotation and can be conveniently mounted either on a bicycle fork or a quick release like the previous versions. This improvement came as a result of cycling trials run in the summer and early fall of 2009. Through enhanced firmware the same sensor can now be attached to a bicycle fork yet still deliver high precision speed and acceleration measurement with less than a second delay.

This unique sensing technology is 360 times more accurate than traditional cycling computers, which count a full 360 degrees of wheel rotation to determine the cyclist's speed. The VeloComputer sensor detects a magnetic field from the magnet attached to the wheel and determines the angle of wheel rotation with 1-degree of accuracy.

Traditional bicycle computers calculate speed with as much as 7 seconds delay, compared to a one second delay with the VeloComputer. This low latency allows VeloComputer to accurately determine a spot speed and acceleration, which is used to calculate torque and power.

The VeloComputer sensor can now be conveniently mounted on the front fork of a bicycle and uses a miniature magnet on a spoke as a measurement reference for a magnetic field. Using tiny, lightweight magnets eliminates the wheel wobbling effect experienced with traditional sensors at higher speeds.

The VeloComputer sensor 3.5 is compatible with VeloComputer 6 and VeloComputer 6L (Light) mobile applications, available for download at http://www.VeloComputer.com. The VeloComputer application works on BlackBerry, LG, Motorola, Nokia, Samsung and Sony Ericsson phones.

The new sensor 3.5 is available as part of a Software Development Kit - SDK. The mass production of this device is planned for Q1 2010 and will be coordinated with the release of a low energy profile by Bluetooth SIG. This bluetooth low energy profile will allow the sensor to operate on a single coin size battery for months, eliminating the need for recharging.

About the company: SoundOfMotion is unique in its focus on developing and licensing innovative technologies for mobile devices and sports applications. SoundOfMotion is a winner of the Orange Design and Innovation contest and a nominee for the Sony-Ericsson content awards 2009. SoundOfMotion was featured in JavaOne 2009, CTIA Wireless, 'Mobile Rules!' by Nokia, 'Top 10 Bike Gadgets' by PC Magazine, Pro-cycling magazine, Bikeradar.com and other media.
