Patent ID: 7735910

Claim:
A wind deflector system for counteracting wind throb noise due to air flow across a vehicle sunroof opening, comprising: a first electrode proximate an edge of the sunroof opening; a second electrode proximate the first electrode; an insulator intermediate the first and second electrodes; a power supply coupled to the first and second electrodes; a controller coupled to the power supply and configured to selectably activate the power supply; and a sensor located proximate the opening and coupled to the controller, the controller receiving information from the sensor and activating the power supply responsive to the information provided by the sensor, wherein an electrical signal generated by the power supply is provided to the first and second electrodes when the power supply is activated, the resulting potential between the electrodes ionizing air proximate the electrodes, the ionized air influencing air flow across the opening to counteract wind throb in a passenger compartment of the vehicle.
