Abstract: A system and method for preventing the double-spending of digital currency that transfers between multiple DLT networks. The system and method includes creating, based on a unit of fiat currency, a first digital currency of a first type on a first DLT network and a second digital currency of a second type on a second DLT network. Each of the first digital currency and the second digital currency simultaneously represent a value associated with the unit of fiat currency. The system and method includes detecting a transaction request to transfer the first digital currency from the first DLT network to the second DLT network. The system and method include locking, responsive to detecting the transaction request, the first digital currency onto the first DLT network to prevent a transfer of the first digital currency from the first DLT network to another DLT network responsive to a subsequent transaction request.

Abstract: In one embodiment, a printed security mark comprises a random arrangement of printed LEDs and a wavelength conversion layer. During fabrication of the mark, the LEDs are energized, and the resulting dot pattern is converted into a unique digital first code and stored in a database. The emitted spectrum vs. intensity and persistence of the wavelength conversion layer is also encoded in the first code. The mark may be on a credit card, casino chip, banknote, passport, etc. to be authenticated. For authenticating the mark, the LEDs are energized and the dot pattern, spectrum vs. intensity, and persistence are converted into a code and compared to the first code stored in the database. If there is a match, the mark is authenticated.

Abstract: In one embodiment, an authentication area on a portable object comprises a random arrangement of printed LEDs and a wavelength conversion layer. The object to be authenticated may be a credit card, casino chip, or other object. When the LEDs are energized during authentication of the object, the emitted spectrum and/or persistence of the wavelength conversion layer is detected and encoded in a first code, then compared to valid codes stored in the database. If there is a match, the object is authenticated. The LED power may be remotely inductively coupled and may flash the LEDs, while the wavelength conversion layer emission slowly decays during its optical detection. The flash of blue LED light may be emitted from the edges of the object, which may act as a light guide, for optical feedback to the user that the object is being authenticated.

Abstract: In one embodiment, a printed LED area comprises a random arrangement of printed LEDs and a wavelength conversion layer. The LED area is embedded in an object to be authenticated, such as a credit card or a casino chip. The object may include a light guide for enabling the generated light to be emitted from any portion of the object. In one embodiment, when the LEDs are energized during authentication of the object, the existence of light emitted by the object is sufficient authentication and/or provides feedback to the user that the object is being detected. For added security, the emitted spectrum vs. intensity and persistence of the wavelength conversion layer is detected and encoded in a first code, then compared to valid codes stored in the database. If there is a match, the object is authenticated.

Abstract: An active target has a target face that is backlit by LEDs, where a detection layer behind the target face detects a new projectile hole in the target, such as from a gun or an arrow. The detection layer may be formed of one or more resistive layers, and the detected increase in resistance due to a new projectile hole being created is sensed and correlated to an XY position of the hole. The location of the new hole is transmitted via an RF signal to the shooter's portable device, such as a smartphone, and the shooter sees the location of the hit relative to the target face in real time. The LEDs may be dynamically controlled. The target is disposable and is supported by a support base containing the control electronics and transmitter.

Abstract: An arrangement for virtually integrating a bot with a search functionality provided by an online search engine enables users of personal computers (“PCs”), mobile phones, and other devices to locate bot content in response to their search queries. The virtual integration enables bot content to be surfaced via the search engine. In response to a query, the search engine may return search results including links to one or more bots that are located on a presence-based network. When the user clicks on a link, a client application is launched on the PC or device that enables the user to converse with the bot using a natural language interface. The virtual integration also provides the bot with context of the user's last known query, or the query history. The bot can then start the conversation at a specific point within the bot's content hierarchy to respond to and answer the user's query.
