Abstract: Location based results are generated for on-line marketing, merchandise searches, and auction items searches. A candidate buyer sets search criteria in an on-line search engine which may include location conditions. Results are presented either graphically or in list form showing the proximity of not only stores that have items that meet the criteria, but the general distance from a reference location. The reference location may be the person's address, a local landmark, a zip code, or other location. According to some condition, only established businesses with actual store fronts or physical locations (which allow for the user to physically inspect the auction item and/or make a risk assessment of doing business with the vendor) are permitted to offer items for auction or be on the selling end of the transaction.

Abstract: A method and a computer system with a specialized graphic user interface for processing trajectory data of a spacecraft and planets. The preferred graphic user interface is capable of representing the orbital trajectory of the spacecraft traveling from one planet to another in 3D and providing user interactions to display the orbit information at any time and position.
