  • Publication number: 20230355223
    Abstract: The present disclosure relates generally to methods and apparatus to control delivery of a sealant during an invasive procedure. Disclosed methods and apparatus control movement of a syringe to control injection of sealant stored therein. For example, disclosed methods and apparatus can displace the syringe body relative to the plunger as the syringe is withdrawn from the target site, rather than displacing the plunger relative to the syringe body, to thereby pressurize the sealant or inject the sealant in an amount proportional to a distance the syringe body is withdrawn. This reduces the variability in the amount of sealant delivered along the syringe withdrawal pathway. The disclosed methods and apparatus can increase precision in movement of a syringe, thereby increasing precision in sealant delivery.

  • Publication number: 20230350999
    Abstract: Systems, methods, and software products provide increased trust in authentication of a user to an authentication server when a trusted witness client device witnesses the authentication of the user on the user's root client device. Both the root and the witness client devices cooperate to present the user with an interactive task during the authentications and each client device independently captures movement of the user performing the interactive task, during which, the user is authenticated to the root client device. An increased level of trust in the authentication of the user is achieved by the authentication server when the captured movements match expected movements of the user performing the interactive task and the authentication server has proof that the witness client devices witnessed a successful authentication.
