Abstract: A method for monitoring at least one sensor is provided. In this context, error words are transmitted from the sensor to the control unit and additional different information characterizing error images is used to enable an adapted response to these parameters by the processor. Extraordinary operating states are indicated in this context in addition to errors. The different error images are recorded in the control unit application phase and result in error image-specific system reactions via a look-up table.

Abstract: Isolated cinacalcet carbamate, processes for the preparation thereof, and processes for the use of cinacalcet carbamate as a reference marker and standard are provided. Also provided are cinacalcet salts substantially free of cinacalcet carbamate, and processes for the preparation thereof.

Abstract: In an optical filter, a thin film is formed by laminating low refractive index layers alternatingly from a substrate side with high refractive index layers. The thin film is provided with first, second, and third laminated portions. In the first laminated portion, the refractive indices of the high refractive index layers become gradually higher. In the second laminated portion, the refractive indices of the high refractive index layers are substantially equal to the highest refractive index of the high refractive index layers constituting the first laminated portion. In the third laminated portion, the refractive indices of the high refractive index layers become gradually lower, and the refractive indices of the low refractive index layers are substantially equal to the lowest refractive index of the low refractive index layers constituting the second laminated portion.

Abstract: A method via which the range of vision in a vehicle's field of view can be determined precisely, so that with the help of range-of-vision information the driver can be advised to modify his driving style. The contrast of an object detected by a radar or lidar sensor is measured by a monocular video sensor, and the range of vision is determined from the measured values supplied by the radar or lidar sensor and by the monocular video sensor. Alternatively, the distance to and contrast of at least one object can be measured by a binocular video sensor, the range of vision then being determined from the measured contrast and distance values.

Abstract: The invention concerns a self-commutating inverter with controlled main valves in a center-tap circuit, with which a commutation capacitor, a series choke and a recovery valve each are associated, and with a transformer for connecting a variable load. In order to reduce the no-load losses, the two series diodes which are customarily connected in series with the main valves, are omitted. Provision is made instead for connecting in series with the commutation capacitor an electronic switching member which can be switched-on together with the main valves.
