摘要： The present invention discloses a novel XRF analyzer capable of simultaneously identifying the presence of a marking composition in a plurality of objects by modulating/varying the intensity of the excitation beam on the different objects and measuring the secondary radiation thereof. The XRF analyzer comprises a radiation emitter assembly adapted for emitting at least one X-Ray or Gamma-Ray excitation radiation beam having a spatial intensity distribution for simultaneously irradiating the plurality of objects; a radiation detector for detecting secondary radiation X-Ray signals arriving from a plurality of objects in response to irradiation of the objects by X-Ray or Gamma-Ray radiation, and providing data indicative of spatial intensity distribution of the detected data X-Ray signals on the plurality of objects; and a signal reading processor in communication with the detector, the processor being adapted for receiving and processing the detected response X-Ray signals to verify presence of the marking composition included at least one surface of each object of the plurality objects.

摘要： A control system and method are presented for controlling operation of an X-ray Fluorescent (XRF) system for detecting at least one material carried by a sample, for example at least one marker carried by the sample. The control system comprises: data input utility for receiving input data comprising material/marker related data about said at least one material/marker; and data processor and analyzer utility. The data processor and analyzer utility is configured and operable for analyzing the input data and determining optimal geometrical characteristics of the XRF system for optimizing operational conditions of said XRF system to maximize amount of primary X-ray radiation that reaches a predetermined region of the sample and is absorbed by a volume of said region and to maximize a portion of secondary radiation emitted from said region that reaches a detector of the XRF system; and for generating operational data to the XRF system enabling adjustment of the geometrical characteristics of the XRF system.

摘要： Methods and systems for verifying compatibility of components of an electronic system are disclosed. The method includes irradiating a first and second components presumably associated with the electronic system, with XRF exciting radiation, and in response thereto, detecting one or more XRF response signals indicative of first and second XRF signatures, emitted from the first and second components. 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. Electronic systems are also disclosed including at least a first and a second electronic components respectively having the first and second XRF marking compositions that enable verification of compatibility of the components.

摘要： Systems and methods for marking of objects, such as keys/key-blanks, in a production line are disclosed. The objects are marked by applying a marking composition(s) to pre-selected areas on the surface thereof. The system includes a marking unit for dispensing a volume of marking composition in one or more localized pre-selected areas on the surface of an object to be marked; a holder/gripper for positioning the object to be marked in one or more positions relative to the marking unit so as to allow the marking unit to dispense the marking composition on the one or more pre-selected localized areas; a reading/verification unit for detecting the marking composition applied to the object thereby verifying that the objects are properly marked; an orientation sensing unit for identifying the orientation of the object to be marked relatively to the holder. The system also includes a controller configured for controlling the operation of the holder, orientation sensing unit, and the marking unit. The reading/verification unit is adapted to identify the marking composition in the one or more pre-selected areas on surface of the object by detecting an electromagnetic signal (such as XRF signal) emitted from the marking composition (e.g. in response to its illumination by X-ray or gamma-ray).

摘要： Methods and system for management of transactions of marked objects are disclosed. In an embodiment, a method for recording a marked object includes: determining specific and unique marking of the object by a reader unit; and communicating encrypted data indicative of the marking and data indicative of the marked object to at least one server system, for generating at least one record of the object and its marking thereat. The at least one server system may be a distributed blockchain system including: at least one blockchain service module adapted for recording transactions of objects in a blockchain; and at least one management service module adapted for authorization of each transaction of an object based on authentication of the transaction by: providing a reader unit with a certain reading scheme/parameters that authorize/enable the reader unit to correctly read the specific marking on the object; and obtaining from the reader unit in response, a reading data indicative of the marking being read using the reading scheme, and authenticating the object based on a match between the reading data and stored data of the object's marking which is stored by the at least one server. In turn, before carrying out a request for recordation of a transaction for the object in the blockchain, the blockchain service module is adapted to await authorization of the transaction from the management service.
