Abstract: Abstract: A method for locally correcting motion in an image reconstructed by a reconstruction system (42) of an imaging system (10) with raw data includes estimating a characteristic feature of a region of interest within the reconstructed image from the raw data, correcting the raw data associated with the region of interest for motion with the estimated region characteristic feature, and reconstructing a motion-corrected image corresponding to the region of interest with the corrected raw data.

Abstract: First and second data is transmitted simultaneously by modulating a first set of signal constellation points, corresponding to the first data, with second data thereby creating a second set of constellation points. The second set of constellation points comprises two subsets corresponding to two values of the first data. The constellation points are selected such that the minimum distance between the first and second subsets is not less than the minimum distance between the constellation points of the first set of constellation points.

Abstract: In a method for setting the transmitted power of a mobile communication device, particularly for a UMTS, a transmitted power that is being asked for at the time is to be set with great accuracy and a good signal-to-noise ratio. The digital signals I, A difference between a measurement of the transmitted power of the signal that is applied to the output antenna (7) and a sequel that is a desired value for transmitted power according to power commands from the base station (12), in such a way that they together produce the desired transmitted power.

Abstract: A lighting unit is described which has a discharge lamp (1), in particular a high pressure or high intensity discharge (HID) lamp or an ultra high performance (UHP) lamp, a lamp driver (2) and a cooling device (3). To reduce mechanical stresses caused by temperature variations in the lamp (1), one or more operating parameters of the lamp (1) are detected. In addition, a control unit is provided for controlling the lamp driver (2) and/or the cooling device (3) at least during switching on and/or off of the lighting unit in such a way that there is no excursion from a predetermined range of the at least one operating parameter. By selecting the parameter range suitably, the service life of the lamp may be extended considerably or the power of the lamp may be increased while the service life remains the same.

Abstract: Luminous units of this kind have light members in the form of incandescent lamps, whose contacts are connected electrically conductive with an electrical connector via an intermediate or contact plate. The contact plate must be fastened separately, owing to which manufacture and assembly are complicated and costly. In order to avoid this, the luminous unit has a light member holder, which is connected with the light member and has a coupling piece for the electrical connector. The coupling connection permits a simple and reliable electrical connection between the light member and the electrical connector. The contacts of the light member have contact pins, which are lengthened by lengthening pins. These allow the contact pins to be directly connected with the electrical connector.
