Abstract: A MEMS yaw-rate sensor is disclosed. In an embodiment, the MEMS yaw-rate sensor includes a first primary mass configured to perform a primary oscillation relative to a main body, a first secondary mass connected to the first primary mass via a first suspension such that a primary movement of the first primary mass excites a primary movement of the first secondary mass and a secondary movement of the first secondary mass relative to the first primary mass is permitted, a first magnetic-field-generating element and a first magnet-sensitive element, one being arranged on the main body and one being arranged on the first primary mass, wherein the first magnet-sensitive element is configured to determine the primary movement of the first primary mass relative to the main body and a second magnetic-field-generating element and a second magnet-sensitive element.

Abstract: A method of medical diagnosis and monitoring using equipment that has wireless electrodes, which are attached to the surface of the skin of the patient. The method comprises collection of data from a patient, converting the data to digital form and transmitting the digital data wirelessly from a patient to a base station located away from the patient where in the wireless transmission between the patient and base station is bi directional.

Abstract: In a GSM mobile radio network having at least one base station controller and a first base station, at least one first frequency channel is made available within a frequency band between the first base station and the mobile stations in order to transmit data and to transmit signaling information. According to the invention, the first base station additionally makes available a second broadband frequency channel with a TD/CDMA transmission method. After a connection has been set up in the first or second frequency channel, a handover of the connection to the respective other frequency channel is carried out by the base station controller without a second base station being selected.

Abstract: A base station for a radio communication system is provided, particularly for a mobile radio network. The base station contains at least two transceivers and at least one antenna for the radio-technical supply of communication connections to at least one remote station. A controller of the base station performs monitoring and organization of the transceivers means such that one of these transceivers means is switched into energy saving mode as soon as it does not supply any communication connections.
