    摘要： The invention relates to x-ray filters in a collimator for controlling the energy of an x-ray beam along a projection axis in computed tomography systems. According to the invention, the filter assembly comprises a filter element for attenuating the x-ray beam, and at least a support plate which fixes the filter element. The filter element and the support plate are notch-shaped in the center part of the filter assembly along a direction perpendicular to the projection axis. The design may free space to be used by other collimator parts and further allows use of more than one filter element in a filter assembly for backup purposes. This simplifies replacement of a defective x-ray filter in the field.

    摘要： An apparatus for determining roll angle of a motorcycle (1) as when taking a curve or bend in a road. The apparatus includes a first gyro sensor (11) that provides a roll rate signal, a second gyro sensor (12) that provides a yaw rate signal, and a velocity sensor (36). The apparatus is configured to integrate the roll rate signal to obtain a first intermediate roll angle value and to determine a second intermediate roll angle value from the yaw rate and the vehicle velocity. The apparatus combines the two intermediate roll angle values into an output value for the roll angle that can be used by a servo (50) to adjust the orientation of the headlamp so that the beam pattern remains leveled with the horizon when the motorcycle (1) rolls when taking a curve.
