Abstract: A server is configured to manage a network of participant devices that are distributed across a plurality of participants in a virtually managed competitive event. Events may be configured and offered via the platform, and participants that have devices meeting certain requirements may register for events. Events that have a high goal for accuracy and verifiability may require a smartphone and smartwatch to be possessed and worn throughout the event in order to gather GPS data, step count, heart rate, fingerprint data, facial recognition images, and other verification data before, during, and after the event. Where data cannot be verified and indicates a technical error or falsification of data, participants may be warned, and their results may be flagged to indicate that they are not verifiable and may be erroneous. Event results may be provided for a plurality of participants with information indicating the accuracy and verifiability of individual results.

Abstract: A clutch for a door lock may comprise an output shaft configured to operate the door lock, and a thumb turn shaft coupled to the output shaft comprising an inclined projection. The clutch may also comprise an input gear configured to be coupled to an actuator output, and a coupler coupled to the input gear such that the coupler and input gear rotate together. The coupler may be configured to translate between an engaged position and a disengaged position, where the inclined projection of the thumb turn shaft is configured to move the coupler from the disengaged position to the engaged position when the thumb turn shaft rotates relative to the coupler. In the disengaged position the coupler may be decoupled from the output shaft.
