Abstract:
Techniques are disclosed for using synthetic jet technology as an air delivery device for sensing applications. In particular, a synthetic jet device is used to deliver a controlled airflow or other fluidic flow to a sensor measurement area. Such a sensing system can be used to detect accurate concentration of target features present in the ambient surroundings, such as gases, particles, solutions, mixtures, and any other environmental features that can be sensed from a controlled airflow. An example application is air quality monitoring by using one or more synthetic jet devices to deliver a known or otherwise controlled airflow to a sensing area, thereby allowing for detection of harmful or otherwise unacceptable concentrations of particulate matter, gases, or air pollutants. In some embodiments, a synthetic jet device is operatively coupled with a sensor via a flow channel in a common housing, so as to provide a controlled flow sensing system.
Abstract:
Embodiments include a synthetic jet device formed within layers of a package substrate, such as to provide a controlled airflow for sensing or cooling applications. The jet device includes an electromagnetically driven vibrating membrane of conductive material between a top and bottom cavity. A top lid with an opening covers the top cavity, and a permanent magnet is below the bottom cavity. An alternating current signal conducted through the membrane causes the membrane to vibrate in the presence of a magnetic field caused by the permanent magnet. By being manufactured with package forming processes, the jet (1) is manufactured more cost-effectively than by using silicon chip or wafer processing; (2) is easily integrated as part of and with the other layers of a package substrate; and (3) can be driven by a chip mounted on the package. Embodiments also include systems having and processes for forming the jet.

Abstract:
Systems and methods of identifying electrical sources of audible acoustic noise may involve identifying first frequency content of a circuit board, wherein the first frequency content is associated with at least one of acoustic noise and a vibration of the circuit board. Second frequency content of an electrical signal associated with the circuit board may also be identified. In addition, a coherence between the first frequency content and the second frequency content may be determined.
