Patent number: 11861430Abstract: A system (100) and a method for marking a product (10) utilize an encoding that specifies the presence or absence of each of a plurality of luminescent materials, at least one of which exhibits a predetermined decay behavior. The decay behavior of a plurality of different materials is detected, and based thereon the presence or absence of the luminescent materials is inferred. A corresponding encoding specifies whether or not the respective materials are present. In this way, different encodings can be associated in advance with different properties of the product (10). The luminescent materials that specify the associated encoding can be applied to the product (10) as a mark (20) in accordance with a determined property of the product (10).Type: GrantFiled: October 13, 2020Date of Patent: January 2, 2024Assignee: SENSOR-INSTRUMENTS ENTWICKLUNGS- UND VERTRIEBS-GMBHInventors: Walter Braumandl, Alexander Baumann, Helmut Löw

Patent number: 10083367Abstract: An accessory is attachable to a portable device equipped with a camera. The accessory includes a camera lens opening and a retainer that retains the portable device such that a lens of the camera of the portable device is aligned with the camera lens opening. At least one source of electromagnetic radiation in the range of ultraviolet and/or blue wavelengths is disposed on the accessory so as to illuminate an object to be authenticated when the object is disposed in front of the camera lens opening of the accessory. A spacer on the accessory positions the accessory with respect to the object to be authenticated so that the camera lens opening has a predetermined positional relationship with a to-be-examined region of the object.Type: GrantFiled: April 26, 2016Date of Patent: September 25, 2018Assignee: SENSOR INSTRUMENTS ENTWICKLUNGS- UND VERTRIEBS GMBHInventor: Walter Braumandl

Patent number: 8546771Abstract: A method for identifying a photoluminescent material that, after excitation with excitation light, emits emission light having different wavelengths is disclosed. The method includes irradiating the photoluminescent material with the excitation light, detecting a temporal intensity curve of at least two emission light components having different wavelengths, which components are emitted from the photoluminescent material as a result of the excitation, calculating initial intensities of the emission light components at a common time, determining at least one intensity parameter by correlating the calculated initial intensities, determining at least one decay parameter value for each of the emission light components from a time progression of their intensity and identifying the photoluminescent material using the intensity parameter(s) and the decay parameter values.Type: GrantFiled: July 18, 2012Date of Patent: October 1, 2013Assignee: Sensor Instruments Entwicklungs-und Vertriebs GmbHInventors: Udo Kraemer, Walter Braumandl

Patent number: 7714302Abstract: An apparatus is disclosed for inspecting a surface containing a material that emits luminescent radiation in response to absorbing excitation radiation. The apparatus comprises a laser disposed in or adjacent to a housing. A sensor opening is defined in the housing and permits emission of excitation radiation generated by the laser and permits admission of the luminescent radiation emanating from the surface in response to the excitation radiation. A sensor monitors whether ambient light is being admitted between an edge of the sensor opening and the surface upon which the sensor opening is in contact. A safety circuit permits the laser to be actuated only when the sensor detects a substantially or completely light-impermeable contact between the edge of the sensor opening and the surface.Type: GrantFiled: July 12, 2007Date of Patent: May 11, 2010Assignee: Sensor Instruments Entwicklungs- und Vertriebs GmbHInventor: Walter Braumandl
