An augmented reality system for procedural guidance identifies a fiducial marker object in a frame of a first field of view generated by a camera, determines a pose of the fiducial marker object, applies the fiducial marker pose to generate a first transformation between a first coordinate system of the fiducial marker object and a second coordinate system of the camera, and applies a pose of a headset to determine a second transformation between the first coordinate system and a third coordinate system of the headset.

An optically variable security element is provided for securing valuable articles, whose areal expanse defines a z-axis perpendicular thereto, having a reflective areal region that displays at least two appearances that are perceptible from different viewing directions. The reflective areal region includes two relief structures arranged at different height levels in the z-direction and form a lower-lying and a higher-lying relief structure, each of which is furnished with a reflection-increasing coating that follows the course of the relief. The higher-lying relief structure displays a first optically variable effect in a first color, and the lower-lying relief structure is visible through the higher-lying reflection-increasing coating itself, or through grid spaces or gaps in the higher-lying reflection-increasing coating and displays a second optically variable effect in a second, different color. The security element is furnished in an interior layer provided contiguously or in some regions, with at least one machine-readable feature substance.

An information processing system includes an information bearing medium and an information reading unit. The information bearing medium has a two-dimensional array of unit data zones. Marks are provided on some of the unit data zones so as to form a digital code. Mark patterns of any two Y-directional adjacent unit data zone strings based on the arrangement of marks in an X-direction differ from each other. The information reading unit generates a data string on the basis of a unit signal formed from a plurality of signals output from a group of detection units that detect the marks in synchronization and recognizes the digital code of the information bearing medium on the basis of a group of the data strings sequentially obtained from the array of the unit data zones.

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 and systems are provided that include receiving an instruction to associate a unique identifier with a digital presentation, where the unique identifier is associated with a tangible object, receiving a first digital asset from a first remote device, determining a first media component to prepend to the first digital asset, determining a second media component to append to the first digital asset (which influences the determination of the first media component or the second media component), incorporating the prepended content, digital asset, and appended content into the digital presentation, and associating the unique identifier with the digital presentation in a data store.

A method, non-transitory computer readable medium, system and/or mobile device for authenticating security features, the mobile device for authenticating security features includes at least one sensor for detecting security features, a memory having stored thereon computer readable instructions, and at least one processor configured to execute the computer readable instructions to receive a target image of a product to be authenticated, the product including at least one security feature, identify the product to be authenticated based on the target image and product information stored in a product database, obtain sensor configuration information for the at least one sensor associated with the at least one security feature of the product based on the identified product, examine the at least one security feature of the product with the at least one sensor based on the obtained sensor configuration information, and authenticate the product based on results from the examination.

An image associated with a poll may be acquired via a camera. One or more symbols indicating responses may be found by analyzing the image. The responses specified by the symbols may be determined and saved. The responses may also be displayed to the operator and/or to the respondents.

A blank for manufacturing molded dental components includes a blank body that includes tooth repairing material. A molded dental component is manufactured by removing portions of the tooth repairing material using a tool. The blank is encoded with at least one structure as a carrier of information regarding properties of the blank body. The at least one structure is arranged such that at least one of a position, dimensions, or a type of structure can be determined by sensing or measuring the blank. In this context, the position, the dimensions, or the type of the structure are embodied such that a value acquired during a determination of the above corresponds to information about a property of the blank body.

Methods, systems, and apparatus for combining preprinted information together with coded sensor information within a two-dimensional barcode. The sensor information may be of an environmental, physical or biological nature, and records a change in status of the environmental or biological condition to which the labeled product has been exposed. A sensor dye chemistry is employed and when a specified condition of the sensed property occurs it causes a change in the color state of sensor dye modules embedded within the sensor-augmented two-dimensional barcode, encoding sensor digital information. Sensor information is recovered utilizing the error-correction feature during barcode reading.

A transaction card with an electronic feedback component is provided. The transaction card may comprise at least one processing device and a substrate component comprising a first substrate surface and a cavity formed in the substrate component. The transaction card my further comprise an electronic feedback component disposed at least partially within the cavity, the electronic feedback component being configured to receive an operation signal from the at least one processing device, the operation signal representing information associated with the transaction card based on an encoding scheme. The transaction card may further comprise a tactile element disposed at least partially within the cavity, the tactile element being actuated by the electronic feedback component based on the operation signal to convey the information to a user.
