Methods and systems for verifying compatibility of components (e.g. parts or devices) of an electronic system are disclosed. In certain embodiments the method includes: irradiating a first and second components presumably associated with the electronic system, with XRF exciting radiation, and detecting one or more XRF response signals indicative of a first and a second XRF signatures, emitted from the first and second components in response to the irradiation. Then the first and second XRF signatures are processed to determine whether they are associated with respectively a first and second XRF marking compositions on the first and second components, and the compatibility of the first and second components to the electronic system is determined/verified based on the correspondence between the first and a second XRF signatures/marking. Certain embodiments also disclose electronic systems including at least a first and a second electronic components/devices respectively having the first and second XRF marking compositions that enable verification of compatibility of the components. Certain embodiments disclose techniques for pairing the first and second components (e.g. devices) based a correspondence between the first and second XRF signatures/markings thereof. Certain embodiments disclose various calibration techniques for calibrating the XRF measurements of XRF markings applied to different substrate materials of the electronic components.

The disclosure features dendritic tags, and methods and systems for fabricating and using such tags. The methods can include obtaining at least one image of a dendritic tag attached to an article, analyzing the at least one image to identify a set of features associated with the dendritic tag, and comparing the set of features to stored information to identify the article.

An implant device identifiable after implantation comprises a main portion of the implant device and a coded portion of the implant device. The coded portion comprises a radiopaque element and indicia on the radiopaque element or indicia as a plurality of radiopaque elements disposed within the coded portion. The indicia are discernible by x-ray, fluoroscopy, computed tomography, electromagnetic radiation, ultrasound, or magnetic resonance imaging.

A method includes at least a portion of an image displayed on a video screen or film, and generating a signal indicative thereof, wherein the at least a portion of the image includes encoded information identifying at least one of a visualization tool or information that are not available without the encoded information, identifying and reading the encoded information, and at least one of invoking the visualization tool or displaying the information identified and read from the encoded information.

The present invention embodies a technique to embed a graphic representation and/or a concealed message such as but not limited to two dimensional codes such as quick response (QR) code matrices, fingerprints, coded fingerprint representations, iris imagery, iris coded representation, biometric hashes, palm print or portraits into a QR matrix code. In the case where biometric data such as finger print representation, iris coded representation or biometric hashes are encoded into the embedding, suitable binary representation of those patterns are generated before encoding. These concealed messages can be further encrypted using any cryptographic method such as public or private key or other suitable encrypting mechanisms adapted to the concealed message. For an implementation of the present invention in which a graphic representation is embedded into the code, the embedding process is based on an optimization method by which the color or luminance of the embedding is modified so as to minimize the visual distortion with respect to a reference image while maintaining the probability of decoding error of the standard and concealed code under a predetermined limit.

The disclosure features dendritic tags, and methods and systems for fabricating and using such tags. The methods can include obtaining at least one image of a dendritic tag attached to an article, analyzing the at least one image to identify a set of features associated with the dendritic tag, and comparing the set of features to stored information to identify the article.

Methods for associating medical images to a patient using a mobile image-capturing device and transmitting the medical images to a storage location are disclosed. One example method includes accessing by a user identifying information associated with a patient through an electronic health record (EHR) application installed in the mobile device, launching a second application on the mobile device from the EHR application, and upon the launching of the application from the EHR application, transmitting the patient identifying information accessed by the user from the EHR application to the second application. The second application may then retrieve one or more medical images stored in the mobile device, associate the one or more retrieved medical images with the patient using the identifying information, and transmit the one or more retrieved medical images with the associated patient identifying information from the mobile device to a storage location.

A spinal implant device identifiable after implantation comprises an outer cage member and an implant body. The implant body is disposed between a first vertebra end and a second vertebra end of the outer cage and defines a plurality of planes. Each of the planes comprises separately readable indicia such that the indicia are discernible by at least one of x-ray, fluoroscopy, computed tomography, electromagnetic radiation, ultrasound, or magnetic resonance imaging.

An implant device identifiable after implantation comprises a main portion of the implant device and a coded portion of the implant device. The coded portion comprises a radiopaque element and indicia on the radiopaque element or indicia as a plurality of radiopaque elements disposed within the coded portion. The indicia are discernible by x-ray, fluoroscopy, computed tomography, electromagnetic radiation, ultrasound, or magnetic resonance imaging.

The present invention relates to systems, entities, and methods for certificates and certifications of documents, such as passports, licenses, degree certificates, and the like. More specifically, the present invention relates to re-certifying a document in the sense of verifying and/or renewing an already existing certificate/certification.
