The Intelligent Way To Sort, Extract & Analyze Signals

Adrian Lincoln — Mon, 10 May 2010 08:28:24 +0000

This note is based on a real requirement presented to Prosig by a prospective user. It’s the sort of challenge that we relish. This case is a great example of a real-world signal processing requirement and also great test of some of the unique features of Prosig’s DATS software. It also shows the power and flexibility [...]

Cooling Down Using Sound Waves

Research at Palo Alto Research Center (PARC) could lead to the replacement of mechanical compressors in refrigerators and air conditioners. The new technology could lead to a threefold increase in the efficiency of these devices. The principle is quite simple – thermoacoustic compressors work in the same way as traditional mechanical compressors. They compress or expand [...]

Sound Steering

The requirement was to develop a ‘standard’ test for assessing the sound quality of power steering pumps in vehicles. Measurements needed to be objective so that the method would be suitable for evaluating dissimilar vehicles and different types of pump.

Noise is an important consideration when a consumer is selecting a new vehicle. It is therefore imperative [...]

Evaluating A Closed Loop Control System For High Pressure Pumps

James Wren — Thu, 29 Mar 2007 11:57:54 +0000

Prosig were recently involved in the validation of a closed loop control system for an automotive pump supplier. The customer has a large number of test cells, each test cell has 8 pumps continually on test. Each pump is instrumented with a revolution or tachometer sensor, giving a once per revolution tachometer pulse. Additionally, there [...]
