Abstract: A method for determining a distance between a cleaning robot and an obstacle. The cleaning robot has a first distance measuring system for a far measuring range and a second distance measuring system for a near measuring range. The second distance measuring system includes a camera. a) if the obstacle is located in the far measuring range, the distance between the cleaning robot and the obstacle is determined by way of the first distance measuring system. b) if the obstacle is located in an overlap region of the far measuring range and the near measuring range, the distance between the cleaning robot and the obstacle is determined by way of the first and the second distance measuring systems; c) if the obstacle is located in the near measuring range, the distance between the cleaning robot and the obstacle is determined by way of the second distance measuring system.

Abstract: A floor cleaning system includes a mobile, self-driving apparatus and a portable additional apparatus for a user. The self-driving apparatus, in particular, is a cleaning apparatus for autonomous treatment of floor areas, such as a vacuuming robot and/or sweeping robot and/or wiping robot. The user apparatus has an operating unit, a communication unit, and a position detection unit. Using the position detection unit, the user defines the floor area to be cleaned in that the user walks, with the additional apparatus, along a cleaning path or delimiting path that can be transmitted to the mobile, self-driving apparatus in order for the mobile, self-driving apparatus to clean along the cleaning path or to clean the floor area included within the delimiting path in accordance with a cleaning request. There is also described a method for the automatic treatment of floor areas with the aid of the floor cleaning system.

Abstract: The present invention provides a method and an apparatus of communication with a first and a second mobile communication network such that the first mobile communication network is different than the second mobile communication network. The method comprises disposing a telematics unit and a gateway unit having a network interface in a vehicle to enable a wireless service and providing wireless coverage within the vehicle for the wireless service on the first or second mobile communication network. Establishment of a personal area network for a wireless coverage within a vehicle and use of a universal gateway access point for accessing disparate mobile communication networks may enable, for example, provision of one or more telematics and mobility services into a vehicle. A remote server of a vehicle service provider may wirelessly communicate with a vehicle over an available mobile communication network regardless of a network type.

Abstract: A radio transmission link between at least one radio transmission device is monitored and at least one radio reception device. Radio transmission links between at least one transmission antenna and one reception antenna are monitored for faults. At least one radio reception device is tuned to the transmission frequency of at least one radio transmission device. The at least one radio transmission device then transmits, during a predetermined time period, a predetermined test signal which is recorded, evaluated and stored as a reference signal in the at least one radio reception device during a predetermined time period. At the start of a test phase, at least one radio transmission device transmits the predetermined test signal. The test signal is compared with the stored reference signal, and an error signal is produced if the comparison result shows that the test signal has changed beyond a predetermined extent with respect to the stored reference signal.
