Abstract: A driving path planning apparatus for an autonomous vehicle includes a driving information obtainer to obtain crossroad information, current velocity, and velocity setting of the vehicle. A global path planner plans a base frame, and an environment recognizer recognizes obstacle on a path and lane information of the vehicle. The apparatus also includes a velocity profile generator to generate a velocity profile for the vehicle, using current velocity and velocity setting, a candidate path planner to plan candidate paths for the vehicle, using velocity profile and base frame, and a path selector to check whether or not the candidate paths have collision risks and select one candidate path of the candidate paths as a driving path for the autonomous vehicle.

Abstract: The present invention relates to a method for preparing a CIS- or CIGS-based light-absorbing layer which is included in a thin film solar cell. More particularly, the present invention relates to a method for preparing a CIS- or CIGS-based light-absorbing layer which ultimately improves the efficiency of a solar cell since the remaining carbon impurities in the formed light-absorbing layer are minimized and additional sulfurization treatment or selenium treatment is made optional, not requisite.

Abstract: The present invention relates to a shopping e-money management service method in an electronic commerce using the internet, wherein the shopping e-money is provided to a newly registered member or a product non-shopper who does not have a product purchase list for a certain period of time such that the member or the non-shopper can use a fixed amount of money like cash for a monthly installment, thereby enabling cost efficiency and inducing continuous purchases.

Abstract: There is provided a ceiling type air conditioner capable of controlling the operation of at least one of a moving unit for moving a brush assembly or a suctioning unit for suctioning foreign matters stored in the brush assembly based on the position of the brush assembly for collecting and storing the foreign matters filtered by a filter. Therefore, it is possible to properly control the movement of the brush assembly to effectively collect and store the foreign matters filtered by the filter. In addition, since a user does not have to exchange or clean the filter, it is possible to prevent inconvenience from being caused by exchanging or cleaning the filter and to prevent the filter from being contaminated.
