    Abstract: A tool for a power drill allows fast and convenient loading and unloading of a screw bit, drill bit, or other implement. The user preferably loads the tool with the necessary implements which are then carried with the tool. Each received implement is movable from a storage position to an in use position in drive engagement with the power drill or power screwdriver. The desired implements can rapidly be changed from one to the other, while the implements are retained on the tool.

  • Publication number: 20030198338
    Abstract: A system and method for routing of telephone calls allows for convenient connection to a party where the telephone address is not known. A database is coded by keywords such as common nickname, trade-mark, or trade name. The system is available to all, and as such, becomes a valuable resource. Problems associated with telephone address recollection are avoided and the advertising message can concentrate on the corporate entity. In this way, contact information is more readily available and can be accessed in different manners using the telephone keypad to query the database.
