Valves based on amplified piezoelectric actuators
6 January 2002
Amplified Piezo Actuators have been developed at CEDRAT TECHNOLOGIES for several years. Their well – known advantages (rapid response and precise positioning) have been used in valve designs to obtain both rapid or fine proportional valves.
Experimental assessment of an active flap device
5 January 2002
During the past thirty years, noticeable consideration has been devoted to the improvement of rotary-wing vehicles, with respect to noise, vibrations and performance. The main rotor of helicopters, and more precisely the blades themselves have been the subject of numerous optimization studies.
Micromoteur et micro-actionneurs piezoélectriques de puissances
1 January 2002
The applications of piezoelectric actuators are spreading in various fields such as precise micro-positioning, shape control or vibration generation, control or damping.
Sounds and ultrasounds transducers
3 January 2001
The Active Materials Applications in the fiel of Motors and Actuators systems are in full expansion at CEDRAT RECHERCHE ans their very general characteristics (which have led to the piezo products) have justified the regular presentations in the flux magazine up to present.
3D ultrasonic imaging probes
1 January 2001
Implementation of 3D capabilities on ultrasonic imaging systems tantalizingly proves the high interest for this diagnosing modality. However, to become a clinical tool, 3D ultrasound has to spend further technological efforts in acquisition performance and probe size to deliver on the fly, quality volumetric images as well as current functionalities.
Linear amplifiers for piezo actuators
1 January 2000
After the development of switching amplifier SA75 for piezoelectric actuator driving, CEDRAT RECHERCHE has developed linear amplifiers. The LA75 electronics are presented in the form of a 19″ rack, and are proposed into various version.
