Abstract:
1. A sensor aperture cleaning system comprising: a substantially linear fluid dispensing arm movable between a stowed position in which the fluid dispensing arm is outside a field of view of a sensor aperture and a cleaning position in which the fluid dispensing arm is disposed within the field of view of the sensor aperture, the fluid dispensing arm including a nozzle; a piston mechanism coupled to the fluid dispensing arm between the nozzle and an articulation point adjacent the sensor aperture; a housing sized to slidably receive the piston mechanism; and a spring disposed within the housing and configured to bias the piston mechanism, wherein the piston mechanism is coupled to the fluid dispensing arm and is configured to move the fluid dispensing arm from the stowed position to the cleaning position and compress the spring in response to an increase in pressure on the piston mechanism from a fluid, and wherein in the cleaning position, the fluid dispensing arm is configured to pivot about the articulation point adjacent the sensor aperture and the nozzle is configured to spray the fluid at the sensor aperture from multiple angles in response to the fluid dispensing arm pivoting about the articulation point.
