Active Tuned Acoustic Damper

The application of DEICON’s patented, active acoustic damper/absorber in adding low-frequency modal damping to small rooms (listening rooms, recording studios, home theaters) is licensed to Modular Sound (the reputable manufacturer of Bag End professional grade speakers). Bag End manufactures electronic bass traps, with the trade name E-trap (TM), based on this technology. The industrial applications […]

Active and Semi-active Vibration Isolation

The conflicting nature of vibration and shock isolation requirements, necessitates design compromises in realizing mounting schemes for systems subject to both vibration and shock perturbations. To avoid making such design compromises, one needs to pursue active and semi-active isolation solutions. One approach to active isolation is combining an active scheme with a traditional passive isolation […]

Vibration and Shock Isolation

DEICON, Inc. was invited to make a presentation on shock and vibration isolation at the global superyacht forum in Amsterdam. The following is an excerpt of the talk. There exist a number of different isolation schemes, e.g., single mounting, double mounting, active isolation, semi-active isolation, air mounting, etc., with different pros and cons. Either one […]

Air Isolation of Diesel-Generators

DEICON’s Computer Controlled Air Isolation System is an adjustable mounting scheme capable of meeting the conflicting vibration and shock isolation requirements. This is a pneumatic system capable of changing its stiffness and changing its damping, depending on isolation requirements. DEICON has installed a number of these air mounting system on a number of gensets (Diesel […]

Seminar on Feedback Control

DEICON, Inc. presented a 3 day seminar on feedback control to Caterpillar engineers in Peoria Illinois. Following some introductory concepts, the seminar covered the design techniques for feedback control applications, with lots of examples and hands-on experiences. The commonly used, popular control strategies such as PI, PD, and PID controllers were emphasized.

Tonal Vibration Absorption of Diesel-Generators

In a recent project, abating the 1 order (25 Hz) transmitted vibration from three 170 KVA marine diesel generators onboard a motor yacht, to the hull of the boat was successfully accomplished using a number of small tuned vibration absorbers. Four tuned vibration absorbers, targeting the 25 Hz vibration, were designed, fabricated, and installed on […]
