  • Publication number: 20130252039
    Abstract: An electrical bypass element, suitable for bypassing defective storage cells in energy storage devices includes two electrical conductors between which is formed a layer sequence with at least one electrical insulation layer and one or more reactive layer stacks, in which an exothermic reaction can be triggered. The reactive layer stacks and the insulation layer are matched to one another such that the insulation layer disintegrates as a result of the thermal energy released during the exothermic reaction and an electrical connection is produced between the electrical conductors. The electrical bypass element can be actively triggered even before the ultimate failure of a storage cell so that higher power losses in the energy storage device can be avoided.

  • Publication number: 20130235970
    Abstract: An image processing device of a computer tomography system includes an interface and a calibration data determiner. The interface is implemented to receive a first set of X-ray recordings of an object to be examined from first discrete recording angles and to receive a second set of X-ray recordings of the object to be examined from second discrete recording angles. The calibration data determiner is implemented to determine calibration data for the computer tomography system on the basis of the first set. The first set is further recorded during a first rotation run wherein the computer tomography system and the object to be examined rotate relative to each other, wherein the second set is recorded during at least a further rotation run after the first rotation run. On the basis of the calibration data and the first and second sets a computer tomography recording is reconstructable.

  • Publication number: 20130223531
    Abstract: A more efficient co-use of dynamic range mapping on the one hand and temporal prediction on the other hand such as, for example, in order to code HDR frame sequences, is achieved by exploiting the concept of weighted prediction in order to transition from the mapping parameter from the reference frame to the currently temporally predicted frame. By this measure, the temporal prediction does not fail and despite the frame-wise variation in the dynamic range mapping, encoding efficiency is, thus, maintained. As a favorable side aspect, weighted temporal prediction is already within the capabilities of existing video coding stages such as, for example, the H.264/AVC.

  • Publication number: 20130226594
    Abstract: An audio decoder includes an arithmetic decoder for providing decoded spectral values on the basis of an arithmetically encoded representation thereof, and a frequency-domain-to-time-domain converter for providing a time-domain audio representation. The arithmetic decoder selects a mapping rule describing a mapping of a code value onto a symbol code representing a spectral value, or a most significant bit-plane thereof, in a decoded form, in dependence on a context state described by a numeric current context value. The arithmetic decoder determines the numeric current context value in dependence on a plurality of previously decoded spectral values. It evaluates a hash table, entries of which define both significant state values amongst the numeric context values and boundaries of intervals of numeric context values, in order to select the mapping rule, wherein the hash table ari_hash_m is defined as given in FIGS. 22(1), 22(2), 22(3) and 22(4).
