Ling Dynamic Systems has released a new shaker, model V9 for use in automotive and aerospace testing. It has a maximum force output of 105kN, and dispalcement of 75mm. It is water cooled and hence is quiet, making suitable for squeak and rattle testing.

Endevco have released 2 new accelerometers for vibration measurements. The 2222D is a lightweight accelerometer (1 gm), the 7268C a tri-axial piezoresistive accelerometer that can be used for automotive crash testing.

They have also release a new signal conditioner 482B which is an 8 channel rack mounted board that is compatible with the TEDS (plug-and-play) type sensors.

Holosonics is selling the “audio spotlight”, an ultra-sonic loudspeaker than generates audible noise by the non-linear behaviour of air. The radiation pattern is a few degrees, so that sound does not disperse like a conventional loudspeaker. A special signal processing amplifier is required to convert audible signals into the ultra-sonic range.

Alpine, a Japanese manufacturer of audio, video and security products for cars, has developed a car audio system called the Alpine F1 Status. Each time the system is switched on, the acoustic characteristics of the cabin are analyzed using a Time Stretched Pulse technique to synchronize the arrival time of sound from the speakers in the car.
