Abstract: Apparatus for deterring birds and animals from roosting on boat decks and other surface areas in form of a mechanical repeller includes a bracket for attachment to a surface area, and a housing including a quick-release fastening device to connect the housing with the bracket. The quick-release fastening device forms a pivotable bearing between the housing and the bracket. At least one pole extends from the housing and a bearing supports the housing in the bearing. An electric motor turns the housing and thereby moves the pole above the surface area. The electric motor includes an output shaft which engages the bracket axially detachable but torque proof. A rechargeable battery is provided and supplied with electric power from a solar cell. The housing is configured in form of a closed module which accommodates the solar cell, an electronic control unit, the electric motor, and the rechargeable battery.

Abstract: In a method and a system for selling authorizations for events or the like, particularly for various types of tickets, sellable authorizations are defined in databases, and an advance booking agency or a purchaser accesses via the Internet the database for reserving and/or purchase of the authorizations. The venues are equipped with admission readers for identifying tickets provided in the form of data carriers, and the admission readers of each venue communicate with an area server, which includes a database of the sold authorizations for this venue. The servers are connected via a network, for example the Internet. The advance booking agencies or private users connect to a Web server by entering suitable addresses. The Web server retrieves the sellable price quotation from the database of the area server over a secure connection, and displays the sellable price quotation on the display of the advance booking office.
