Various implementations include an optically readable coded device. The device includes a body having a first surface and a second surface opposite and spaced apart from the first surface, wherein the second surface defines a cavity. The cavity has a cavity interior surface spaced apart from the second surface. The first surface defines one or more code openings extending from the first surface to the cavity interior surface and in fluid communication with the cavity. The cavity has a cavity cross-sectional area in a plane parallel to the first surface, and the code openings have a code opening total cross-sectional area at the intersection of each code opening and the cavity interior surface. The cavity cross-sectional area is larger than the code opening total cross-sectional area. The code openings define an optically readable code on the first surface.

A method of inserting a data structure into a component using a 3D printer is provided. The method includes providing the data structure having at least one structural parameter associated with the component, converting the data structure into indicia representative of the data structure, and manufacturing the component containing the indicia.

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 matrix barcode on a can component, such as a can end panel, a pull tab of a can end, or the coil stock, is formed by laser application that makes spots that represent the matrix barcode modules.

There is provided an adornment having a machine readable code integrated therein for establishing a communication channel over a network between a computing device and a server, the adornment comprising an adornment body sized and shaped for wearing on an appendage of a body of a human, wherein the machine readable code comprises a plurality of gems which are inlaid in the adornment body, wherein the machine readable code encodes an identifier for establishing the communication channel between a computing device imaging said plurality of gems and a remote data storage device storing at least one media content item designated for presentation on a display of the computing device.

A transaction card includes at least one metal layer having one or more apertures therein. A light guide is disposed beneath the metal layer. The light guide has a light output and a light input. The light output is positioned to transmit light through at least the one or more apertures of the metal layer. At least one LED is positioned to transmit light into the light guide light input.

The disclosure relates to a tool part for a cutting tool having an identification marker arranged at the tool part, wherein the identification marker is a unique machine readable code associated with individual dimension information data. The individual dimension information data includes at least one individually measured dimension of the tool part as measured when manufacturing the tool part that will change while wearing the tool part. The disclosure further relates to a system, a method and computer program product for utilizing an identification marker on a tool part for a cutting tool, for determining a tool wear of the tool part.

Techniques for utilizing an unused space on a connector are disclosed, where the connector is commonly seen in a multi-wire cable. The connector itself includes at least one major surface. The surface includes a message, wherein the message gets gazed at by a user when the user slides the connector into a socket of a device. The message becomes invisible after the connector is fully positioned or inserted in the socket. A counter is provided to record a number of times the connector has been used in the socket. The counter may be used by a party to allocate a set of advertisements for the user in accordance with a profile thereof or as the number of times the message has been gazed by the user.

The invention relates to a blank for the production of a dental shaped body, wherein the blank has a corpus (2) of tooth restoration material, from which the shaped part to be fabricated is carved by means of a tool (4) by removal of material. The blank has coding means (1) formed on part of the surface (6) of the blank corpus (2), which coding means (1) has at least one structure (8, 9) for identification of the blank. The coding means (1) consists of a plurality of panels (5.1) at the level of the surface (6) of the corpus (2) and a plurality of panels (5.2, 5.3) incorporating a flat structure (8, 9) at a level (h1, h2) which is distinguishable from at least the level of the surface (6) of the corpus (2). The invention further relates to a method for identifying a blank with the aid of coding means (1).

A method for producing a security feature for a data medium, includes the steps of: providing a molding means having a molding structure of a representation of the security feature; introducing the representation into a substrate by impressing the molding structure; and arranging a light-diffractive or light-refractive structure on the substrate.
