Flower (acoustic) power
A Japanese company called Let’s Corporation has released a product that consists of a vibration shaker attached to a plastic tube that can vibrate a bunch of flowers. The vibrating flowers emit sound.
See the Let’s Corporation web site for more details.
ANSYS v8.1 available
ANSYS finite element analysis software version 8.1 is now available. Read the ANSYS web site for the new improvements in this latest version.
Microstrain release new wireless sensors
Microstrain have released a set of wireless sensors such as tri-axial accelerometers, inclinometers, strain gauges, and thermocouples. The wireless devices have a range of about 30m.
Active damping for vehicle suspension
ZF Sachs are selling Continuously Damping Control (CDC) shock absorbers that uses an electronic variable valve to control oil flow. The units were availabe in 2001 on the BMW 7 series as an option, and is now available on the VW Phaeton, and the Opel Astra.
