  • Sensor for Detecting the Amount of a Reducing Agent and the Amount of a Pollutant in an Exhaust Gas
    Publication number: 20120055139
    Abstract: A system assembly detects the amount of reducing agent and the amount of pollutant in an exhaust gas. The system assembly has a first pollutant sensor, which is cross-sensitive to the reducing agent, and is provided for emitting a first measuring signal proportional to the amount of pollutant in the exhaust gas for use in front of a filtering device for the selective reducing of the reducing agent or the pollutant in the exhaust gas. A second pollutant sensor, which is also cross-sensitive to the reducing agent, emits a second measuring signal proportional to the amount of pollutant in the exhaust gas for use behind the filtering device.

  • Nonlinear precoding method for a digital broadcast channel
    Patent number: 8130854
    Abstract: Several subscriber signals are transmitted simultaneously and at the same frequency by a central transmitter to several decentralized receivers which do not cooperate with each other, by digital message transmission in a broadcast channel. A common transmission signal, which enables an error-free individual reception, should be generated with knowledge of all subscriber signals and of the current transmission conditions, by signal preprocessing methods on the transmission side. Known nonlinear precoding methods totally suppress the interference signals, so that the channel diversity cannot be used. In the claimed precoding method, the occurring interference signals are, on the contrary, taken into account.

  • Computed tomography gantry rotor
    Patent number: 8130900
    Abstract: A rotor of a gantry of a computed tomography apparatus is produced at least in sections in a differential style from bar-shaped basic elements. Due to the differential style of the rotor, the rotation mass is reduced to a significant degree given a simultaneously maintained rigidity and stability of the rotor 1, such that high rotation speeds can be realized with a comparably small dimensioning of the rotor drive.

  • Internal routing
    Patent number: 8131604
    Abstract: Methods and apparatus provide for routing goods from a source location to a final destination through an intermediate location. An intermediate warehouse task or transfer order is generated with reference to the movement of the goods to the intermediate location rather than movement to the final destination. A routing table can provide information for generating the intermediate warehouse task. A routing path that indicates the intermediate location can correspond to a location determined by a layout-oriented routing path or a process-oriented routing path.

  • Arrangement for cooling of an electrical machine
    Patent number: 8129877
    Abstract: In one aspect, an arrangement for cooling of an electrical machine is provided. A rotor and a stator include an air-gap arranged between the rotor and the stator. The rotor and the stator include a circulation arrangement to allow the circulation of air for cooling-purposes of the rotor and of the stator. The rotor and the stator are encapsulated by a shell which is formed to allow the flow of hot air from the rotor and the stator to a heat-exchanger. The shell is formed to allow the flow of cool air from the heat-exchanger back to the rotor and the stator for cooling-purposes. The shell includes a number of corners, while each corner is used to gather the hot air before it is guided to the heat-exchanger.

  • Method and apparatus for correcting distortion during magnetic resonance imaging
    Patent number: 8131048
    Abstract: In a method and apparatus for correcting distortion during magnetic resonance imaging k space data in a number of readout encoding directions, sampling points on the phase encoding lines are primarily in low frequency regions of k space and the number of such sampling points is less than that of all sampling points. A view angle tilting compensation gradient is superimposed on the axis of a layer selection gradient. The k space data acquired from the number of directions are then combined.

  • Establishment of a transcoder-free operation connection
    Patent number: 8130683
    Abstract: When a request is sent by a switching unit, relating to the use of at least one subset of a codec mode configuration for the establishment of a transcoder-free operation connection by a radio network controller, it is checked whether the at least one requested subset is supported by the radio network controller. If the at least one subset of at least one codec mode configuration is supported, a transcoder-free operation connection to the switching unit and to the communication terminal is established by the radio network controller. Furthermore, a message relating to the at least one subset of the codec mode configuration to be used is signalled from the radio network controller to the communication terminal for the transmission of data.

  • Scalable method for encoding a series of original images, and associated image encoding method, encoding device and decoding device
    Patent number: 8131088
    Abstract: A series of decoded images is generated from a series of original images encoded by a first encoding technique following movement-compensated, predictive encoding, where a starting image of a group of successive original images that are to be encoded is defined by a second encoding technique following movement-compensated, temporally filtered partial band encoding based on a determined encoding property of a decoded image of the group of images that are to be encoded, the decoded image is used for generating an output image having a low resolution level, before the images are encoded. At least one output image is generated on each level of resolution from the successive original images of the group of from at least one decoded image during image encoding. The decoded images are provided only with a reduced quality while the reconstituted images are of great quality.
