Method for the Detection of Errors in Pump Units

A method is provided for detecting faults in a pump assembly having an electric motor, or faults in an electric motor, having at least one rotating shaft. A vibration signal is detected, the detected vibration signal is processed in a manner such that the influence of the current rotational speed of the shaft is eliminated, periodic signals are filtered out of the processed vibration signal, and the vibrational operating condition, in particular possible faults, is recognized by way of the periodic signals. Further, a pump assembly having an electric motor or an electric motor is provided in which this method is applied.

Adjustment device and adjustment method for a tomography apparatus

In an adjustment device and method for a tomography apparatus for aligning of a patient support device and an acquisition system relative to one another, a reference laser projects onto a reference element associated with the patient support device, the reference laser being directly associated with a rotary frame of the acquisition system, such that tolerances in the alignment between the reference laser and the acquisition system are prevented. Moreover, due to the arrangement of the reference laser directly on the rotary frame of the tomography apparatus, a simple calibration between laser beam and the acquisition plane of the acquisition system is ensured by a displacement of the reference laser in two different rotation angle positions which exhibit an angular interval therebetween of substantially 180 degrees.

Hearing apparatus with a special charging circuit

Provisions to charge the battery of a hearing apparatus without having to remove the battery from the housing are provided. A hearing apparatus separates charging contacts, which are disposed on the surface of the housing and serve to charge the battery, from the battery and to connect the battery to an amplifier circuit, when the battery is not being charged. Otherwise, when the battery is being charged, the hearing apparatus connects the charging contacts to the battery and separates the battery from the amplifier circuit. This double switching function means that the amplifier circuit is protected from charging power surges and also in the normal operating state of the hearing apparatus electrochemical reactions at the charging contacts are avoided.

Semiconductor Wafer Of Single Crystalline Silicon and Process For Its Manufacture

Semiconductor wafer of monocrystalline silicon contain fluorine, the fluorine concentration being 1·1010 to 1·1016 atoms / cm3, and is free of agglomerated intrinsic point defects whose diameter is greater than or equal to a critical diameter. The semiconductor wafers are produced by providing a melt of silicon which is doped with fluorine, and crystallizing the melt to form a single crystal which contains fluorine within the range of 1·1010 to 1·1016 atoms / cm3, at a growth rate at which agglomerated intrinsic point defects having a critical diameter or larger would arise if fluorine were not present or present in too small an amount, and separating semiconductor wafers from the single crystal.
