A blister pack includes a housing having a plurality of cavities and a cover sealed to the housing and enclosing the cavities. The cover including a base layer, at least one security element, and a heat protective layer. The heat protective layer includes one of an amorphous polymer and a semi-crystalline polymer.

A wearable device includes a wireless receiver, a processor, a memory component, and a graphical display. The wireless receiver is configured to be in wireless signal communication with a remote user device so that the wireless receiver can receive a programming signal from the remote user device. The memory component stores non-transitory computer-executable instructions that, when executed by the processor, cause the wearable device to display one or more graphics at the graphical display. Upon receiving the programming signal from the remote user device, the processor can execute the non-transitory computer-executable instructions to cause the processor to generate an interface input signal based on the received programming signal and convey the interface input signal to the graphical display to cause the graphical display to display one or more graphics corresponding to the interface input, and thus corresponding to the programming signal.

A blister pack includes a housing having a plurality of cavities and a multi-layer film sealed to the housing and enclosing the cavities, the multi-layer film including a base layer, at least one security element, and a heat protective layer. The heat protective layer is comprised of one of an amorphous polymer material or a semi-crystalline polymer material and is positioned to insulate the at least one security element from heat applied to the heat protective layer during heat sealing of the multi-layer film to the housing, the heat protective layer functioning as a heat sink for protection of the at least one security element during heat sealing of the multi-layer film to the housing.

An optical device includes an array of lenses and a plurality of first and second segments disposed under the array of lenses. At a first viewing angle, the array of lenses presents a first image for viewing without presenting the second image for viewing, and at a second viewing angle different from the first viewing angle, the array of lenses presents for viewing the second image without presenting the first image for viewing. In some examples, individual ones of the first and second segments can comprise specular reflecting, transparent, diffusely reflecting, and/or diffusely transmissive features. In some examples, individual ones of the first and second segments can comprise transparent and non-transparent regions. Some examples can incorporate more than one region producing an optical effect.

The invention relates to a method for detecting and/or identifying magnetic supraparticles using magnet particle spectroscopy (MPS) or magnet particle imaging (MPI), wherein magnetic supraparticles are provided, each of which contains a plurality of magnetic nanoparticles and which have a specific composition and/or structure. The magnetic supraparticles are exposed to at least one magnetic field, whereby at least one voltage and/or a voltage curve is induced based on the magnetic moment of the magnetic supraparticles. The at least one voltage and/or the voltage curve is detected as at least one measurement signal, and at least one spectrum is generated from the at least one measurement signal, said spectrum containing harmonics, each of which has an amplitude and a phase. The magnetic supraparticles are (uniquely) detected and/or identified using the at least one generated spectrum.

A system and method for creating latent image indicia that includes a variable mark. The latent image indicia is made of pigmented ink that can only be viewed when illuminated with a specific frequency of light. The pigmented ink is printed in a solid patch by a conventional printing process. The variable mark in the pigmented ink is created by laser ablation of the pigment. The laser ablation is done after the ink printing as a separate step.

An authentication method includes receiving, at a processor, a signal representing an image of a serialization code and multiple flecks of a label, the flecks having a random distribution. The processor detects the serialization code and applies a modification to the image to produce a modified image. A subset of flecks of the modified image is detected, and metrics associated with each fleck from the subset of flecks are identified. The identified metrics are compared with metrics associated with a unique signature, and a message is displayed, via a user interface, indicating an authenticity of the label based on the comparison.
