  • Patent number: 6742918
    Abstract: A system for adjusting the direction of a light beam from a headlamp assembly comprises a condenser lens which is movable along an arcuate path. As a vehicle turns a corner, the system moves the condenser lens along the arcuate path, so as to direct the light beam in the direction that the vehicle is moving. Because the condenser lens follows an arcuate path, the light beam is not distorted, allowing for greater angular displacement of the light beam.

  • Patent number: 6561677
    Abstract: A night light having a base unit with a central cavity designed to house a light sensor, a printed circuit board, a light bulb, and a pair of electrical prongs. Attached to the front surface of the base unit is a fixed half-spherical lens. Disposed over the lens is a rotating, half-spherical cap having an approximately quarter-spherical sized opening that allows a portion of the lens to be exposed so that light from the light bulb located inside the lens may shine therethrough. Thus when the outer cap is selectively rotated around the base unit, the quarter-spherical sized opening is rotated therewith, and a dissipated broad beam of light may be selectively aimed in any 360 degree direction.
