  • Patent number: 8232061
    Abstract: A method for examining an attachment or detachment of living cells, dead cells or cell-like particles on a surface using plasmon resonance includes irradiating a measurement region with beams over the entire angle of incidence spectrum and capturing, combining and evaluating beams with identical angles of incidence reflected from different points of the measurement region with a determination of the angle of light incidence with a lowest reflected light intensity and measuring an angle of incidence shift of an intensity minimum that occurs. The evaluating includes registering different angles of incidence of two or more intensity minima occurring simultaneously to reflect a respective level of the surface accumulations.

  • Patent number: 7973934
    Abstract: The plasmon resonance sensor (1) comprises a chip (2) of transparent plastic with a gold layer (3) made up of narrow part surfaces (4), arranged in a row, on the inner side of which light from a planar light source (12) is convergently guided. A Fourier lens (24) integrated in the chip (2) forms the reflected angular spectrum on the detector (23), arranged at a focal separation (F) from the integrated Fourier lens (24) for temporal determination of the incident angle with a resonant intensity minimum of reflected light. An incident lens (13) brings about imaging of the planar light source (12) in the form of lines of light on the part surfaces (4), which are further imaged in the form of lines of light on the detector (23).

  • Publication number: 20110067678
    Abstract: An internal combustion engine has an air intake system with an air intake pipe and which communicates with a combustion chamber of a cylinder as a function of a switch position of a gas inlet valve. Furthermore, a compressor is disposed in the air intake system and is embodied for the purpose of compressing a mass air flow. Also, a throttle valve is disposed in the air intake system downstream of the compressor and by which the compressed mass air flow into the air intake pipe can be throttled. The internal combustion engine furthermore has a differential pressure sensor which is disposed in the air intake system and is embodied for the purpose of measuring a differential pressure between a charge pressure that prevails downstream of the compressor and upstream of the throttle valve and an ambient pressure that prevails outside of the air intake system.

  • Publication number: 20100286992
    Abstract: A computing device includes a processing unit and a memory with instructions that, when executed by the processing unit, cause the processing unit to create: a business software processing module that manages business application software for a plurality of businesses. The business processing software module comprises a customization module, a registration module and an activation module. The customization module stores and processes definitions for business solutions that permit a business application external to the computing device to be integrated with business application software included on the computing device. The registration module makes the business solutions available to users of the computing device. The activation module generates an activation token and a web page for each request to activate a business solution. For each activation request, the activation module redirects the web page to a URL specified in the business solution definition corresponding to the activation request.

  • Publication number: 20100185379
    Abstract: Actual values of a load variable are detected by a sensor during active model trimming under different valve pressure conditions, and a model of estimated values is created. Trimming values of a model parameter are determined depending on detected and modeled values such that when the model parameter is trimmed, the modeled values approximate the detected values. A function is determined depending on the different pressure conditions and approximated to the trimming values. At different pressure conditions first lambda control values are detected. A first controller value fitted function is determined depending on the pressure conditions and approximated. When the model trimming mode is not active, second lambda control values are detected at different pressure conditions. A second controller value fitted function is determined depending on the pressure conditions and is approximated. An error of the intake system is detected depending on the fitted functions.

  • Publication number: 20100095331
    Abstract: A method and apparatus for performing template-based prefix caching advantageously identifies common prefixes (i.e., initial video segments) in video titles, stores common prefixes only once in a prefix cache, and uses these common prefixes when serving requests for video content. This advantageously enables a prefix cache to scale to a large number of video titles, since the cache stores each common prefix only once. A new video title that uses an already existing prefix may be advantageously added without requiring additional storage in the prefix cache. Template-based prefix caching also advantageously reduces the bandwidth required to distribute prefixes when new titles are ingested into the system—if the required template is already available in the prefix cache, prefix-caching is enabled instantly for this title and no additional bandwidth is required to distribute the prefix.

  • Patent number: 7693270
    Abstract: A method and communication network for providing a subscriber with a blend of services of the communication network delivered to the subscriber through a telephone and services delivered to the subscriber through a TV delivery system in communication with the network. Upon receipt of a message from a calling party, a service broker function may be configured to execute service package information associated with services of the TV delivery system subscription to include obtaining and delivering caller ID information of the calling party. The service broker function may be configured to alter the message request to generate a modified message request in respect to information affecting alerting of the subscriber's phone. The modified message is sent to the subscriber's phone so that, while information of the calling party is displayed on the TV delivery system, alerting of the phone is modified.

  • Publication number: 20100057748
    Abstract: The invention includes a method and apparatus for promoting a data item within a data distribution network. In one embodiment, a method includes monitoring at least one parameter for the data item where the data item is associated with an application or service, propagating the data item from a first data server toward a second data server based on the monitoring of the at least one parameter for the data item, and propagating, toward at least one device, a message indicative of the propagation of the data item from the first data server toward the second data server. The message is for adapting the at least one device to identify the second data server as a source of the data item capable of serving future requests for the data item.

  • Publication number: 20100028903
    Abstract: The invention relates to the examination of the attachment or detachment of living or dead cells, or cell-like particles, or other surface accumulations on surfaces, by means of plasmon resonance. The reflected light is evaluated such that two or more intensity minima of the reflected light occurring within a time frame are registered in a time dependant manner for different incident angles. The registered measurement signals reflect the respective amount of the surface accumulation. In case two intensity minima have occurred at the same time, valuable information about particular processes regarding the surface accumulation, for example regarding the adhesion of cells, can be obtained. Said information is of particular importance in the field of medicine/biology.

  • Patent number: 7555107
    Abstract: The concept of “roaming” is extended to wireline networks with a network hosted technique which emulates a wireline telecommunications network user's environment when the user is using a wireline telecommunications device located at a physical location other than his or her “home” location, or when using a wireline or wireless telecommunications device other than his or her own regardless of the location. Any telephone or other telecommunications device being used by the user advantageously appears to be logically connected directly to his or her home telecommunications network, irrespective of the location of the telephone or other telecommunications device being used and the telecommunications network to which that device is actually connected.
