    Abstract: A synthetic jet assembly includes a synthetic jet having a cavity and an opening formed therein. The synthetic jet assembly also includes an actuator element coupled to a second surface of the body to selectively cause displacement of the second surface, and a control unit electrically coupled to the actuator element. The control unit is configured to transmit a multi-frequency drive signal to the actuator element, the multi-frequency drive signal comprising a cooling frequency component and an acoustic frequency component superimposed on the cooling frequency component. The cooling frequency component causes a cooling jet to eject from the opening of the body. The acoustic frequency component produces a desired audible output.

  • Patent number: 10012367
    Abstract: A female lighting socket connector of a light fixture can be removed to expose electrical leads of the fixture. When an electric light is present within the female light socket, the electric light can be removed prior to removing the female lighting socket. A short end of a universal adjustable L-bracket can be affixed to a structural member of the light fixture. A positionable planar LED array can be attached to a long end of the bracket to place the LED in a forward facing position. The position can permit the light emitted from the LED to illuminate an immediate area. Electrical leads of the LED can be directly connected to the exposed electrical leads of the light fixture. The removal and connecting steps can prevent backwards compatibility. When the LED is connected to the fixture, the bracket and the LED can be substantially within an enclosure and/or a hood.
