An electric hand tool has an electric consumer, a movable operating element and a control unit for controlling a current flow between the energy store and the consumer on the basis of the position of the operating element. The control unit is constructed separately from the operating element and the mechanical position of the operating element is converted into an electrical control signal in the control unit.

Electric hand tool having a discrete operating element

A handheld power tool, in particular an electric handheld power tool, includes an actuable drive device configured to drive a tool and an illumination device. The illumination device is connected to an acceleration sensor and varies its generated light depending on movements of the handheld power tool that are detected by the acceleration sensor.

The disclosure relates to an electrical device having a control unit. A near field communication device connected to the control unit is provided.

Electrical device, electrical device system

In a method for operating an electric device, which includes a first storage battery pack, a second storage battery pack and an electrical load, no more than one storage battery pack is discharged at any given time to operate the load. In the process, the storage battery pack to be discharged is selected as a function of a temperature of the first storage battery pack and a temperature of the second storage battery pack and/or as a function of an internal resistance of the first storage battery pack and an internal resistance of the second storage battery pack.

A switch/circuit board unit and a hand-held tool equipped with such a switch/circuit board unit are proposed. The switch/circuit board unit is adapted for installation in a handle of the tool and has a switch and a circuit board. The switch/circuit board unit also has a mechanical coupling element for producing a rigid mechanical coupling between the switch and circuit board. The rigid coupling that the coupling element produces between the switch and circuit board allows the arrangement of the switch and circuit board to be embodied as a unit, which can enable maneuvering before installation and permit a simplified installation, and in particular, it is possible to simplify a fastening of the switch and circuit board inside a housing of the tool, and in the accompanying installation of electrical connections, for example in the form of flexible cables, it is possible to avoid an incorrect placement or wedging of cables.

The present invention provides a method for operating information systems for providing information to a driver in a motor vehicle, via which method increased driving safety may be obtained. In accordance with the present invention, the information to be output to the driver is selected as a function of vehicle operating data, so that the driver is provided with select information adapted to the particular driving situation, without the driver being unnecessarily distracted from the main task of driving the vehicle.

A method for transferring at least one navigation element from a vehicle navigation unit to a master station. The vehicle navigation unit does not include a database sufficient for a route calculation, including an input device via which a user is able to input navigation element data concerning at least one navigation element, the vehicle navigation unit including communications devices, or cooperating with separate communications devices, to exchange data with a master station in which routes are calculated. The vehicle navigation unit includes an arrangement to select at least one navigation element database entry, of a plurality of navigation element database entries, which are transmitted by the master station as response to the navigation element data transmitted to the master station, when the master station is not able uniquely to assign a plurality of navigation element database entries to at least one navigation element.

Mobile radio communication messages transmitted by a message service to a terminal are linked to reference information items and tested in the terminal according to validity criteria. The messages are only stored in a non-volatile memory when they are valid; and they are not stored when they are invalid, and/or they are erased from the nonvolatile memory after having been previously stored when they are later determined to be invalid.

Method and device for managing mobile telephone messages

A method for the transmission of data using radio transmission systems between transmitter/receiver stations is provided, and a computer for the allocation of radio transmission systems for the transmission of data between transmitter/receiver stations is provided, which serve to select radio transmission systems dynamically, for a communication from at least one transmitter/receiver station, on the basis of a subscriber profile, a location of the one transmitter/receiver station, and/or a speed of the transmitter/receiver station, in order to transmit data between transmitter/receiver stations. A computer in a switching device calculates which radio transmission system best meets the criteria. During a data transmission, it is possible to switch automatically to a further radio transmission system if the transmission quality of the radio transmission system currently being used declines.

METHOD FOR TRANSMITTING DATA BETWEEN MASTER/SLAVE STATIONS BY MEANS OF RADIO TRANSMISSION SYSTEM AND COMPUTER FOR THE ALLOCATION OF RADIO TRANSMISSION SYSTEMS FOR THE TRANSMISSION DATA BETWEEN MASTER/SLAVE STATIONS

A terminal and a method for a terminal using services offered by a master station is proposed. The method allows a user-configured service to be activated at a terminal which is limited in its input possibility. In this context, a first terminal transmits activation data to the master station over a first data network. With the assistance of the activation data, a service identification and a terminal identifier are transmitted to the master station. In the master station, a service is selected as a function of the service identification. The master station transmits service data corresponding to the selected service as a function of the terminal identifier so that the service data is recognized by the first terminal upon reception and initiates functions for implementing the selected service at the first terminal.
