Abstract: After an emergency call from a communication terminal has been received by an emergency call center, the position of the communication terminal is determined by querying a database. An area around the position of the communication terminal is defined as danger area and other communication terminals located in the danger area are identified. Communication terminals of rescue workers in the danger area who are to be informed are then selected. Finally, emergency information is generated, which can, for example, contain information about escape routes for potentially imperiled persons or access route information for rescue workers. This emergency information is then communicated to each of the selected communication terminals of potentially imperiled persons and/or rescue workers.

Abstract: A mobile device which is assigned to a person transmits an identification to a central device where localization of the mobile device is initiated. After the mobile device has been located in an area of an access system, the identification is checked for authorization for access via the access system. Access via the access system is either allowed or denied based on the result of the check. Access by an authorized person to secure areas or devices with the aid of a wireless device which is usually carried along—for example a mobile radio terminal or a DECT terminal—thus becomes considerably easier and more convenient.

Abstract: Registering energy consumption in part of a building, an item of state information of at least one energy load being acquired, the state information being transmitted to a control center, and the state information, a state duration and a specific statement of the consumption of the energy load being used to determine and evaluate the energy consumption in the control center. It is possible to dispense with separate energy consumption measuring units as a result of the energy consumption being registered by multiplying the switched-on duration by a specific statement of the energy consumption (that is to say power) of the energy load.

Abstract: A magnetic recording disk is patterned into discrete magnetic and nonmagnetic regions with the magnetic regions serving as the magnetic recording data bits. The magnetic recording layer comprises two ferromagnetic films separated by a nonferromagnetic spacer film. The spacer film material composition and thickness is selected such that the first and second ferromagnetic films are antiferromagnetically coupled across the spacer film. After this magnetic recording layer has been formed on the disk substrate, ions are irradiated onto it through a patterned mask. The ions disrupt the spacer film and thereby destroy the antiferromagnetic coupling between the two ferromagnetic films. As a result, in the regions of the magnetic recording layer that are ion-irradiated the first and second ferromagnetic films are essentially ferromagnetically coupled so that the magnetic moments from the ferromagnetic films are parallel and produce a magnetic moment that is essentially the sum of the moments from the two films.
