  • Publication number: 20110270711
    Abstract: Networked services may interface with enterprise systems of an organization to access data in the enterprise systems. A networked service may be able to retrieve, manipulate, and store data in the enterprise systems. Once a networked service interfacing with enterprise systems has been created, developers may create apps or applications that call one or more networked services to access data in the enterprise systems. The apps may provide basic functionality, such as generating a user interface in a specific device using a specific industry standard platform for incorporating data from enterprise systems accessed by a linked service. Networked services may also contain modules for tracking calls or invocations of the service together with an identifier of an associated application and user, in addition to other data. This data may be recorded in a database and shared to compensate parties based on actual usage of the services and/or apps.

  • Publication number: 20110096386
    Abstract: The invention makes it possible to adjust the light intensity of a laser scanning microscope laser beam in an economical manner and with high accuracy. A separate acousto-optic component can be omitted in that a light modulation section such as an electroabsorption modulator (EAM) or a semiconductor amplifier (SOA) is arranged directly at the laser diode, advisably at one of its front sides. It is nevertheless possible to control the light intensity economically and with high accuracy because the important parameters of the laser beam remain unchanged when the optical output power is changed by the light modulation section. The light modulation section is preferably formed integral with the laser diode in at least one material layer.

  • Publication number: 20110051234
    Abstract: A laser scanning microscope (LSM) having variable light intensity and a control method for the same. The light intensity of a laser beam in an LSM has been controlled to date with high accuracy, but also high costs by means of an acousto-optic component (AOM, AOTF). According to the invention, such a component for beam modulation is to be omitted, without reducing the exposure accuracy of the sample. In an LSM, a directly modulated laser diode (10) is used with an electric control (12) for direct modulation. Said laser diode (10) has a turn-on delay of the light intensity that is dependent on the amount of the control variable when subjected to an electric control variable. The control (12) is designed such that the fluctuation width (??tV) of the occurring turn-on delay (?tV) is smaller than 1 ?s, particularly smaller than 0.5 ?s. Thus highly exact modulation without an acousto-optic component is possible.

  • Patent number: 7649683
    Abstract: Process for observing at least one sample region with a light raster microscope by a relative movement between the illumination light and sample via a first scanner along at least one scanning axis essentially perpendicular to the illumination axis wherein several illuminated sample points lie on a line and are detected simultaneously with a spatially resolving detector. At an angle to the plane of the relative movement, a second scanner is moved and an image acquisition takes place by coupling the movement of the first and second scanners and a three-dimensional sampling movement being done by the illumination of the sample. The second scanner is coupled to the movement of the first scanner such that straight and/or curved lines and/or plane and/or curved surfaces are scanned which are extended along at least one scanning direction of the first scanner as well as along the scanning direction of the second scanner.

  • Patent number: 7593158
    Abstract: A method in which specimens are examined using a microscope. For an illuminated specimen, spatially coherent light with at least one continuous wavelength range or a continuously tunable wavelength range is generated, and one or more wavelengths or wavelength ranges in the illumination light are selected in dependence on the prespecified method of examination. The specimen is then illuminated with the illumination light with the selected wavelengths or wavelength ranges, the illumination light and the emission light coming from the specimen are then subsequently separated, whereby the back radiated illumination light is suppressed in the detection beam before the detection and the emission light is detected. In such a method, the selection of the wavelengths or the wavelength ranges of the illumination light is tuned by means of the separation of the detection light and the illumination light and the suppression of the illumination light in such a manner that a prespecified control variable (R) is optimized.

  • Patent number: RE41666
    Abstract: A process for confocal microscopy is disclosed in which laser light is coupled into a microscope beam path, directed successively with respect to time onto different locations of a specimen, and an image of the scanned plane is generated from the light reflected and emitted by the irradiated locations. A change in the spectral composition and in the intensity of light is are carried out during the deflection of the laser beam from location to location, while the deflection continues in an uninterrupted manner. In this way , so that at least two adjacent locations of the specimen located next to one another are acted upon by light with different spectral characteristics and by laser radiation of different intensity. By periodically interrupting the coupling in of the laser light during the deflection of the microscope beam path, it is made possible that only selected portions of the image field are acted upon by the laser radiation. A laser scanning microscope for carrying out this process is also disclosed.
