Abstract: A motor drive includes a device for safe fitting of the motor drive with a circuit breaker. In at least one embodiment, the device includes a first cover, whose position can be altered, for example by being guided in slotted links, in such a way that only the receiving opening provides a free space for receiving the handle, owing to the overlap by the first cover, and therefore it is only possible for the circuit breaker to be fitted on the motor drive when the handle is in the corresponding position.

Abstract: In a method for determining a coefficient of friction between a motor vehicle tire of a motor vehicle and the surface of a roadway, a first coefficient of friction parameter (?est—used,ij) is determined using a model (RM) in which a functional correlation between the first coefficient of friction parameter (?est—used,ij) and a slip (Sij) of the motor vehicle tire is set. A second coefficient of friction parameter (?quasi—meas—used,ij) is determined from the quotient between a longitudinal force (FL) and a vertical force (FZ) of the motor vehicle tire. The first and the second coefficient of friction parameters (?est—used,ij, ?quasi—meas—used,ij) are used to determine the coefficient of friction (?R,ij) by a recursive estimation algorithm.

Abstract: A method for operating wheel electronics of a tire checking system includes providing wheel electronics having a battery-free power supply encompassing at least one rechargeable power storage medium for supplying power to the wheel electronics. The wheel electronics can be operated in a reduced-power transmission mode and a subsequent normal transmission mode. In the modes, data that relate to tire-specific parameters and are determined by the wheel electronics are transmitted to a vehicle-mounted communication device in the form of modulated transmission signals, with less transmission power being used for the transmission signals in the power-reduced transmission mode than in the normal transmission mode. Wheel electronics and a tire checking system are also provided.

Abstract: A radially expansible annular stent is disclosed. The stent comprises a plurality of stenting turns around a lumen centred on a longitudinal axis.

The method includes cutting the connector struts from a tubular workpiece with a laser beam. The laser beam is aimed so as to be offset from a longitudinal axis of the workpiece to provide the reduced radial thickness of the connector struts.
