Abstract
A window having a frame with a windowpane disposed therein is provided. A first impedance discontinuity element is disposed between the windowpane and the frame adjacent a portion of a periphery of the windowpane. A second impedance discontinuity element is disposed adjacent another portion of the periphery of the windowpane. The first and second impedance discontinuity elements have different impedances.
Claims39
A window comprising:
- a frame;
- a windowpane disposed within the frame;
- a first impedance discontinuity element disposed between the windowpane and the frame adjacent a portion of a periphery of the windowpane;
- and
- a second impedance discontinuity element adjacent another portion of the periphery of the windowpane, the first and second impedance discontinuity elements having different impedances.
A window comprising:
- a frame;
- a plurality of windowpanes disposed within the frame, each of the plurality of windowpanes substantially parallel to another of the plurality of windowpanes, each of the plurality of windowpanes separated from another of the plurality of windowpanes by a gap;
- and
- first and second impedance discontinuity elements adjacent a periphery of each of the plurality of windowpanes, the first and second impedance discontinuity elements having different impedances, the first and second impedance discontinuity elements of adjacent windowpanes of the plurality of windowpanes staggered relative to one another.
A window comprising:
- a frame;
- a windowpane disposed within the frame;
- a passive impedance discontinuity element adjacent a portion of a periphery of the windowpane;
- and
- an active impedance discontinuity element disposed between the windowpane and the frame adjacent another portion of the periphery of the windowpane, wherein the active impedance discontinuity element is activated so that the active and passive impedance discontinuity elements have different impedances.
A window comprising:
- a frame;
- a windowpane disposed within the frame;
- an actuator disposed between the windowpane and the frame adjacent a periphery of the windowpane;
- a sensor disposed between the windowpane and the frame adjacent the periphery of the windowpane;
- and
- a controller having an input electrically coupled to the sensor and an output electrically coupled to the actuator.
A method for controlling vibration in a window, the method comprising:
- disposing a windowpane within a frame;
- and
- creating an impedance discontinuity adjacent a periphery of the windowpane.
A method for controlling sound radiation from a window, the method comprising:
- disposing a plurality of windowpanes within a frame so that each of the plurality of windowpanes is substantially parallel to another of the plurality of windowpanes and so that each of the plurality of windowpanes is separated from another of the plurality of windowpanes by a gap;
- and
- creating an impedance discontinuity adjacent a periphery of each of the plurality of windowpanes.
A method for controlling sound radiation from a window, the method comprising:
- sensing vibrations adjacent a periphery of one or more windowpanes of the window;
- and
- adjusting an impedance at the periphery of the one or more windowpanes based on the sensed vibrations.
A method for controlling vibration in a window, the method comprising:
- sensing vibrations adjacent a periphery of a windowpane of the window;
- determining a vibration energy of the windowpane from the sensed vibrations;
- determining a stiffness distribution at the periphery for modifying a vibration energy distribution within the windowpane when the vibration energy of the windowpane exceeds a predetermined value;
- and
- modifying the vibration energy distribution within the windowpane by adjusting an impedance at the periphery of the windowpane when the vibration energy of the windowpane exceeds the predetermined value.
