20120217403 | A METHOD AND DEVICE FOR IDENTIFYING A MATERIAL - A material may be identified using THz radiation that simultaneously or sequentially includes at least one first frequency portion and a second frequency portion different therefrom. An object formed from the material to be identified is irradiated with the THz radiation and the THz radiation exiting the object is detected using a phase-sensitive THz receiver. A time or phase offset, caused by the object, is measured at least for the first frequency portion and a material thickness is determined therefrom. Attenuation of the received signal, at least for the second frequency portion, is determined. An absorption coefficient for at least the second frequency portion is calculated using the material thickness. | 08-30-2012 |

20130306869 | IMPROVED-EFFICIENCY FIBRE-COUPLED TERAHERTZ SYSTEM - A terahertz system can be configured for producing and coherently detecting terahertz radiation. The system can comprise a laser light source and two THz antennas, a first of which is used as a transmission antenna and a second of which is used as a receiver antenna, which are each optically coupled to the laser light source by an optical fibre and can be activated by light from this laser light source, wherein the THz antennas each have a semiconductor chip to which antenna conductors have been contact-connected and which comprises at least one photosensitive active layer with a band edge wavelength which is longer than a wavelength of the laser light source and at least one layer, adjoining the active layer, with a band edge wavelength which is shorter than the wavelength of the laser light source, wherein the band edge wavelength of the active layer of at least one of the THz antennas is at least 200 nm longer than the wavelength of the laser light source. | 11-21-2013 |
20140319356 | METHOD AND APPARATUS FOR DETERMINING A SUBSTANCE USING THZ RADIATION - The invention relates to a method for determining a liquid in a closed container using THz radiation, in which a first and a second measurement are carried out, wherein the THz radiation is emitted in the direction of the liquid for measuring properties of the liquid, and a portion of the THz radiation coming from the direction of the liquid is detected. In the proposed method, the closed container contains, in addition to the liquid, a gas, wherein a wall of the container is transmissive for THz radiation and wherein the detected portion of the THz radiation in the first measurement is reflected at a boundary surface between the wall and the gas or a pocket containing the gas, and in-the second measurement is reflected at a boundary surface between the wall and the liquid. The first measurement thus serves as a reference measurement for capturing disturbing losses in the THz beam path and for determining influences of the wall on a measurement result for the second measurement. The invention further relates to an arrangement suitable for carrying out this method. | 10-30-2014 |

20120011439 | DETERMINING EVENT PATTERNS FOR MONITORED APPLICATIONS - A method, system, and computer program product for providing information of a monitored system through a graphical user interface (GUI) of a monitoring application to support simplified or automatic identification of events. The method includes, among other possible operations, initiating an event pattern script recording. The method also includes keeping track of user actions on said GUI and on activated GUI panels during said event pattern script recording by requesting a user to specify, once the user activates a further GUI panel, which panel information in a current GUI panel triggered activation of said further GUI panel and based on what criterion the triggering occurred. The user specified information results in triggering information. The method also includes, in response to receiving an indication that an event has been identified, stopping said event pattern script recording. The method also includes, storing said event pattern script recording containing identification information identifying the event, GUI panel information about said activated GUI panels during said event pattern script recording and said triggering information. | 01-12-2012 |
