Abstract: A retroreflective article including a binder layer and a plurality of retroreflective elements. Each retroreflective element includes a transparent microsphere partially embedded in the binder layer. At least some of the retroreflective elements include a reflective layer that is a locally-laminated reflective layer that is embedded between the transparent microsphere and the binder layer. At least some of the locally-laminated reflective layers may be localized reflective layers.

Abstract: A retroreflective article comprises a binder layer and a plurality of retroreflective elements, each retroreflective element comprising a transparent microsphere partially embedded in the binder layer. At least some of the retroreflective elements comprise a first locally laminated layer and a second locally laminated layer that may be reflective layers. A transfer article comprises a disposable carrier layer in which the retroreflective article is detachably disposed with at least some of the transparent microspheres in contact with the disposable carrier layer.

Abstract: A control system and method which automatically responds to a stalling motor due to a brush head binding or hanging event, and which automatically prevents backlash damage to the electronics when the brush head is freed from it's constraints.

Abstract: Systems and methods for managing media, such as digital content, using block chain technology are described. In some embodiments, the systems and methods perform multiple digital currency transfers between address nodes to register a collection of rights to a digital content item to a block chain, and perform a digital currency transfer transaction between address nodes to register the collection of rights to the block chain.

Abstract: Systems and methods for managing media, such as digital content, using blockchain technology are described. For example, the systems and methods can facilitate the storage of documents, such as legal documents, along with associated tokens (e.g., non-fungible tokens or NFTs) to a blockchain or similar platform, such as the Ethereum decentralized platform. Further, the systems and methods access digital wallet information or contents and provide digital content to users, such as during auctions or within online marketplaces, when the digital wallet information indicates certain contents or tokens.

Abstract: Systems and methods for managing media, such as digital content, using blockchain technology are described. For example, the systems and methods provide rights-enabled tokens, such as non-fungible tokens (NFTs), which include information identifying content represented by the tokens as well as information or data that identifies the rights assigned or associated with the content represented by the tokens.

Abstract: A thermic infusion system includes a thermal tubing system and a control system. The thermal tubing system has a tubal body with at least one tubal segment. The tubal segment includes a thermal element that may receive energy, such as electrical energy, to increase temperature within the tubal body. The control system may regulate the amount of energy received by the tubal segment using one or more sensors positioned within the tubal body.

Abstract: Systems and methods for managing media, such as digital content, using block chain technology are described. In some embodiments, the systems and methods may access digital content items provided to a social network service, generate bitcoin addresses that represents rights to the digital content items, transfer digital currency between a rightbase to the generated bitcoin addresses to create the rights to the digital content items, receive an indication that a member of the social network service is authorized to perform an action using the digital content items within the social network service, and transfer digital currency from the generated bitcoin addresses associated with the rights to the digital content items to bitcoin addresses associated with the member of the social network service.

Abstract: Systems and methods for managing media, such as digital content, using block chain technology are described. In some example embodiments, the systems and methods provide rights of a digital content item to a user, by transferring digital currency from a parent address node associated with an owner of a digital content item to a child address node associated with a recipient of a right to the digital content item, and recording the transfer of the digital currency from the parent address node to the child address node in a block chain associated with the digital content item.

Abstract: Systems and methods for managing media, such as digital content, using block chain technology are described. In some example embodiments, the systems and methods register a digital content item to a content management system using an authentication module that authenticates a digital content item as an authentic content item and a transaction module that performs a block chain transaction to register the authentic content item to the content management system. The authentication module may perform a multiple operation authentication process for the digital content item, and determine a trust value calculated from the performed multiple operation authentication processes satisfies a threshold value associated with authenticating the digital content item as authentic.
