Abstract: An optical system to facilitate vehicle operation, a cleaning system to clean an optical element of the optical system and a hollow, protective plastic enclosure for use therein are provided. The cleaning system includes a flexible house having first and second ends, a nozzle fluidly coupled to the hose at the first end of the hose and a hollow protective plastic enclosure having a passageway extending through the enclosure and housing a portion of the hose within the passageway. The enclosure is configured to receive a camera assembly within an interior of the enclosure. The nozzle is configured and positioned at the first end of the hose to direct the flow of a cleaning fluid therethrough to an exterior surface of a transparent optical element to clean the exterior surface to allow the camera assembly to have an unobstructed view of an environment outside the vehicle.

Abstract: A communications headset has two earpieces mounted on a headband, one at each end. The earpieces are mounted on the headband by arcuate members or stirrups which provide for pivoting of the earpieces about an axis in the plane of the headband, or parallel thereto. A boom attachment member is rotatably mounted on the back of one of the earpieces and the boom is mounted on the attachment member for pivotal and swinging movement. A receiver can be in both earpieces or only in the earpiece carrying the boom. The boom carries an electret microphone and associated amplifier.
