Abstract: The invention relates to a method for generating executable code (10, 10?) that is intended to be executed on a mobile end device (12, 12?) having at least one app builder unit (16) with at least one memory unit (18) in which at least one base code (24, 24?) is stored, and which has at least one input module (20) and at least one generating module (22), wherein required functions and/or data (D1, D2, D3, D4) are entered through the input module (20) by a user in a first procedural stage (SI) and the generating module (22) embeds at least part of the required functions and/or data (D1, D2, D3, D4) in the base code (24, 24?) in a later procedural stage (S4).

Abstract: Rechargeable batteries are used as a power supply in the most varied electrical devices. Parallel to this, connections with other energy sources are frequently available, at least for part of the time, in order to charge the rechargeable batteries during this time. Particularly efficient lithium ion batteries have the problem that short charging/discharging cycles cause them to age just as much as long cycles, during which the user can derive greater benefit from them. It is the task of the invention to ensure particularly effective use of rechargeable batteries during charging/discharging cycles of the most varied duration. This is achieved in that the rechargeable battery is divided into cells, of which only one is charged, in each instance, and the others stand ready to provide energy. If the network voltage stops, charging of the cell just being charged is completed from the other cells.

Abstract: To allow drivers of different vehicles to make contact with one another, a user terminal is provided in the vehicle, which accesses a server having a connected database. By way of this database, contact with another user who is also entered in the database, might be using the same travel route, and is therefore noticed by the user, can be established by inputting a vehicle license plate as a user ID. When a travel destination is input into a navigation device, the travel route calculated is entered in the database, and the server automatically undertakes a comparison with travel routes of other users who are contained in the database, and establishes contact between the users who have correlating user data sets.
