Abstract: A camera assembly in a vehicle includes a housing installed in the vehicle. A camera is mounted to the housing and movable relative to the housing between a first position where the camera can take an image of an occupant of the vehicle and a second position where the camera is blocked by a portion of the housing. In one example, the camera can be moved from the first position to the second position by rotating a knob mounted to the housing.

Abstract: A camera assembly includes a housing. A camera is mounted to the housing. A cover is disposed over the camera. The cover has a variable opacity. When the camera is being used, such as for authentication, the cover is substantially transparent. When the camera is not being used, the cover is substantially opaque, to reassure the user's sense of privacy.

Abstract: In an electrostatic precipitator system powered by a primary power source, the power supply has a converter and a high voltage device. The converter can be coupled to the primary power source for producing a converter voltage with a different frequency content. The high voltage device is driven by the converter, producing from its converted voltage a high voltage. This high voltage is influenced by the different frequency content, having at least one frequency component at a predetermined low frequency which is sized to promote efficient precipitation.
