This disclosure, and the exemplary embodiments provided herein, include a system and method for encoding information in a relatively dense and time-varying manner. In exemplary embodiments, a reflector or retroreflector is wrapped around a rotating member, such as a cylinder, (also referred to as “Rotational LIDAR Barcodes”), which encodes relatively longer data messages, as compared to a static barcode, which can be detected by a LIDAR system and decoded from every direction, i.e. bearings angles of 0-360 degrees, even when partially obstructed.

The invention concerns an electronic device, which includes a memory for storing data, a processor for processing data, and an output device for showing machine-readable code containing the data for reading using a reader device. The electronic device includes a data-transmission interface for arranging a data-transmission link with one or more external devices, to which the electronic device is to be arranged to act as a user interface. The invention also relates to a data-transmission system including the electronic device and a server.

A functional component and having a partial plastic housing element with a plastic housing wall, the plastic housing wall having a device identification region integrated into the plastic housing wall and thus realizing a constituent part of the plastic housing wall. The device identification region comprising identification elements integrated into the plastic housing wall, those identification elements that realize part of a surface of the plastic housing wall realizing device identification elements, the device identification region being realized individually for the device by the device identification elements, such that the device can be unambiguously identified by means of the device identification region.

A barcoded indicator operative to provide a machine-readable indication of exceedance of at least one threshold by at least one product quality affecting parameter, the barcoded indicator including at least a first barcode and at least a second barcode, the at least a second barcode being in a second barcode unreadable state prior to exceedance of the at least one threshold and upon exceedance of the at least one threshold the at least a first barcode becoming unreadable and generally simultaneously the at least a second barcode becoming readable.

A pill bottle for prescribed pills includes: a circular top portion having an aperture; a circular bottom portion; walls that form a cylinder and connect the circular top portion with the circular bottom portion; and a pattern of electrically conductive ink disposed on an exterior surface of the walls.

The technology described herein allows a sender to initiate generation of a collaborative asset, which may be a video generated by merging videos provided by a group of users. The technology can facilitate the generation and collection of digital assets, such as video, images, and audio recordings from a group of users designed by the sender. The collaborative asset may be associated with a tangible object using a unique identifier located on the tangible object. The collaborative asset may be stored in computer memory on a user-experience server and associated with the unique identifier. When the unique identifier is provided to the user-experience server a second time, the collaborative asset can be retrieved and output to the computing device that provided the unique identifier. Thus, a user can initiate generation of a collaborative asset.

The invention concerns device for a digital writing instrument the device comprising a substrate with a transparent or translucent layer and a pattern layer on the transparent layer. The pattern comprising an active area made with photoluminescent material and an inactive area made with non photoluminescent material. The photoluminescent material comprises a successive alternate of a first layer and a second layer generating photoluminescent structure at the interface of said first layer and said second layer, the pattern layer comprises a series of N points distributed in a plan (X,Y), either said N-points define the active area whereas the inactive area is defined by the area between said N points. The N-points defines the inactive area whereas the active area is defined by the area between said N points. The invention also relates to a method for determining a position, a method for manufacturing, a system and a stylus.

A window including a base substrate, which includes a transmission region and a bezel region in a plan view and includes a front surface and a rear surface that are opposite to each other in a thickness direction, a light-blocking layer, which is disposed on the rear surface of the base substrate and is overlapped with the bezel region, and a printing layer, which is disposed on the light-blocking layer and has a target surface, in which a barcode pattern is formed. The printing layer may have a chromatic color, and a width of the printing layer may be less than a width of the light-blocking layer.

A quality management system for products including a multiplicity of barcoded quality indicators, a barcode indicator reader and a product type responsive indication interpreter, each of the barcoded quality indicators including a first barcode including at least one first colorable area, the first barcode being machine-readable before exceedance of the at least one time and temperature threshold, at least a second barcode including at least one second colorable area, the second barcode not being machine-readable before exceedance of the at least one time and temperature threshold, a coloring agent located at a first location on the indicator and a coloring agent pathway operative to allow the coloring agent to move, from the first location to the first and second colorable areas simultaneously thereby causing the first barcode to become unreadable and at the same time causing the second barcode to become machine-readable.

A waste stream is analyzed and sorted to segregate different items for recycling. Certain features of the technology improve the accuracy with which waste stream items are diverted to collection repositories. Other features concern adaptation of neural networks in accordance with context information sensed from the waste. Still other features serve to automate and simplify maintenance of machine vision systems used in waste sorting. Yet other aspects of the technology concern marking 2D machine readable code data on items having complex surfaces (e.g., food containers with integral ribbing for structural strength or juice pooling), to mitigate issues that such surfaces can introduce in code reading. Still other aspects of the technology concern prioritizing certain blocks of conveyor belt imagery for analysis. Yet other aspects of the technology concern joint use of near infrared spectroscopy, artificial intelligence, digital watermarking, and/or other techniques, for waste sorting. A variety of further features and arrangements are also detailed.
