  • Patent number: 8301304
    Abstract: A detecting apparatus and method of a robot cleaner is disclosed. The apparatus includes a detecting unit provided with a transmitting unit for sending a signal to detect the floor and a receiving unit for receiving a signal sent from the transmitting unit to be reflected on the floors an optic angle adjusting unit disposed at least one of the transmitting unit and the receiving unit and configured to adjust optic angles of the signals, and a light shielding unit configured to partially shield a signal sent through the optic angle adjusting unit in order to reduce a deviation of each signal of the transmitting unit and the receiving unit. Accordingly, a measurement deviation with respect to color and feel of the floor can be reduced. Also, an amount of light received at the receiving unit can be obtained as much as required, which allows an accurate detection of the detecting apparatus. In addition, even if there are both drop-off and bump on the floor, the robot cleaner can smoothly operate.

  • Publication number: 20080225419
    Abstract: A varifocal mirror and a camera module comprising the same are disclosed. The varifocal mirror comprises a substrate, a thin film having a circumference supported by the substrate and a variable radius of curvature, and a reflective plane attached to the thin film to reflect light. The reflective plane has a radius of curvature varying in response to variation in the radius of curvature of the thin film. The camera module embodies focus and optical zoom functions via actuation of the varifocal mirror instead of using an electromagnetic actuator, a step motor and the like when adjusting positions of lens units, significantly reducing a volume of the overall system. With this structure, the camera module can be applied to various portable digital assistances requiring a minimized camera module, such as PDAs, mobile phones and the like.
