Abstract: The present disclosure relates to a method of forming a cast component and a method of forming a casting mold. The method is performed by connecting at least one wax gate component to a ceramic core-shell mold. The ceramic core-shell mold includes at least a first core portion, a first shell portion, and a second shell portion, wherein the first shell portion is adapted to interface with at least the second shell portion to form at least one first cavity between the core portion and the first and second shell portions. The core-shell mold may be inspected and assembled prior to connection of the wax gate component. At least a portion of the ceramic core-shell mold and the wax gate component is coated with a second ceramic material. The wax gate component is then removed to form a second cavity in fluid communication with the first cavity.

Abstract: A storybook application to provide an audio recording of a story recorded by Reader and delivered to Recipient via a link, eliminating the need for paper books and recording devices. A Reader, guided by highlighted story text records their voice reading a story into the application. Upon completion of the recording. Reader saves or deletes the recorded story with audio and visual files stored separately for later synchronization and personalization of paced reading. A link to the recorded story is delivered to the chosen Recipient with an optional note. The Recipient receives a link and clicks the link to access the recorded story within the application via Recipient's personal device. The words of the story are also highlighted to guide the reading pace of the Recipient, which may be altered to suit the Reader. The application also presents the stories in other languages.

Abstract: A system for verifying information associated with a user can include at least three devices. The first device is configured to transmit, to the second device, user-associated information, a unique identifier associated with the user-associated information and an identity digital signature generated using an identity private key associated with the user and a message comprising a previously determined hash of a portion of the user-associated information combined with the unique identifier. The second device is configured to generate the hash of the portion of the user-associated information combined with the unique identifier and transmit the generated hash and the identity digital signature to the third device. The third device is configured to lookup the generated hash in a database, verify the identity digital signature using the identity public key related to the generated hash in the database, and upon successful verification, transmit a success response to the second device.
