TLDR
In this paper, a sensor element in the surface measures certain flow values in the boundary layer, conveyed to an analyzer control circuit which, in turn, conveys a signal to an active vibration transmitter in the body for providing the required control.
Abstract
In controlling the boundary layer of flow over the surface of a body, for reducing resistance and impeding flow separation, a sensor element in the surface measures certain flow values in the boundary layer The measured values are conveyed to an analyzer control circuit which, in turn, conveys a signal to an active vibration transmitter in the surface of the body for providing the required control

Method and apparatus for structural integrity monitoring

TL;DR: In this article, a system for monitoring a structure and detecting disturbances and faults associated with such a structure is described, which includes an actuation device for mechanically exciting the structure and a sensing device for transducing vibrations experienced by the structure, and digital signal processing means for processing signals output by the sensing device.

Synthetic jet actuator and applications thereof

TL;DR: In this paper, a flexible metallized diaphragm forms a wall of the housing and can change the volume of the chamber when moved, and an electrical bias is imposed between the metallization and the electrode by a control system.

Synthetic jet actuators for cooling heated bodies and environments

TL;DR: In this article, a synthetic jet actuator is used to generate a cyclical flow of the fluid jet, along the heated body and about a heat sink surface, which is then rejected to the ambient where it mixes and cools down.
Patent

Micromachined synthetic jet actuators and applications thereof

TL;DR: In this article, a train of vortex rings are formed by the motion of the diaphragm and is advanced away from the jet under self-induced velocity. And a piston-like actuator can then be realized by using a “bossed” orifice.

Control of laminar flow in fluids by means of acoustic energy

TL;DR: In this paper, the authors proposed to reduce the point of transition from laminar flow to turbulent flow in aerodynamic boundary layers on the surfaces of aircraft by radiating acoustic energy at frequencies greater than twice the critical TollmeinSchlichting frequency into the boundary layer.
