Abstract: Systems and methods for linking an authentication account to a device may include processor(s) to maintain a plurality of authentication profiles, each authentication profile corresponding to a respective user and including at least one profile image, an immutable identifier, and authentication data used to authenticate the respective user. The processor(s) may receive a request including the device key, an immutable identifier, and a biometric image captured by a camera of a client device. The processor(s) may identify a subset of authentication profiles having respective immutable identifiers that match the immutable identifier from the request. The processor(s) may compare feature(s) extracted from the biometric image of the request to features extracted from the a profile image of the subset of authentication profiles, and link the device key of the client device with an authentication profile in a data structure to register the client device with the authentication server.

Abstract: Methods and systems are presented for improving operation of an evaporative emissions system. In one example, the methods and systems estimate a fuel vapor concentration based on output of a fuel tank level sensor and output of a fuel pressure sensor. A canister purge valve is adjusted to an initial position at a beginning of a fuel vapor purging cycle to reduce a fuel vapor purging time.

Abstract: One aspect of the present disclosure includes a system comprising prosthetic chordae, at least one attachment member including a channel, a female securing member, and a papillary penetration member configured to pass through the channel, the chordae, and the securing member when implanted in a patient's heart. The penetration member includes an axis.

Abstract: A system includes a pre-sized prosthetic chordae, a papillary penetration member, and a female securing member. The pre-sized prosthetic chordae is directly connected to an attachment member. The papillary penetration member extends through both the chordae and the attachment member. The female securing member receives the penetration member. The penetration member is an axis about which the chordae pivot.

Abstract: A pre-sized prosthetic chordae assembly includes a male attachment unit and a female securing member. The male attachment unit includes a plurality of pre-sized prosthetic chordae fixedly connected to at least one male attachment member and a papillary muscle penetration member that is connected to and extends substantially axial to the at least one male attachment member. The female securing member is for receiving the papillary penetration member.
