  • Patent number: 7004599
    Abstract: The present invention relates to an illuminated personal hygiene mirror for viewing facial skin or other areas of the body. In each of the embodiments of the present invention, a hand-held frame receives and supports a mirror. The mirror is covered with a polarizer for polarizing any reflected light falling thereon. A light source is positioned within the frame about the periphery of the mirror and is covered by a polarizing filter for polarizing light emitted therefrom. The mirror polarizer and light source polarizer are out of phase providing cross-polarized light to the eye of the user. An integral handle supports the frame and is held by the user when viewing facial skin. Other embodiments of the present invention include the same components, except a two-way mirror is employed and the mirror frame has a removable back portion to allow viewing by a second person. Other embodiments include an illuminated mirror employing cross and parallel polarization using two light sources.

  • Patent number: 6273585
    Abstract: An improved bathroom-use mirror lamp having a mirror lamp and gimbal frame that are capable of a flexible range of angular adjustment. A gimbal frame is situated on the upper extent of the lower base, and a mirror lamp is mounted to the gimbal frame, with the gimbal frame containing internally routed electrical wiring. The electrical wiring of the mirror lamp is routed from the interior section of the mirror lamp through the two lateral arms of the gimbal frame and extended out at the bottom end of the lower base. The gimbal frame and mirror lamp each have a laterally disposed semicircular shaped recess at a connection section with a position limiting ball bearing in each. When the mirror lamp is rotated 180 degrees, the position limiting ball bearings become restricted against two edges of the insertion conjointment slots, causing the mirror lamp to become incapable of further rotation and preventing the twisting of the electrical wiring.

  • Patent number: 5959792
    Abstract: An ergonomic vehicle inspection mirror apparatus has a handle, a pole or casing, and a foot. Mounted on the foot is a rotatable mirror. The mirror is attached to the foot by means of a pivot shaft, about which the mirror is capable of two degrees of rotational freedom, in order to turn the plane of the mirror at various angles with respect to the foot. Rotation about the pivot shaft is actuated by an electric motor in the foot. The motor is interconnected with a toggle switch in the handle. Pushing the switch in a particular direction causes the mirror to rotate in that direction. The inspector can place the foot of the device under the vehicle with the pole at an attitude that is chosen to be comfortable. Thereafter, the mirror may be rotated with the switch so as to direct the line of sight at various points under the vehicle body without having to readjust the pole for each angle of view.
