Abstract: The present technology pertains to restoring a directory to a state prior to a past synchronization event. A content management system can present an interface including history of synchronization events for a directory, and a user can select to restore a directory to a state prior to any one of the past synchronization events.

Abstract: An electric machine may include a housing having a front end and a back end where the front end is the primary mechanical coupling end. The electric machine may include a stator and a rotor arranged within the housing and a shaft connected to the rotor. The shaft may extend out of the front end of the housing and the shaft may be configured to be rotationally driven by the rotor or to rotationally drive the rotor. The electric machine may also include an electronic controller configured to control operations of the rotor and stator and the electronic controller may be mounted on the front end of the housing.

Abstract: A method of controlling a permanent magnet turbogenerator/motor includes providing a protected load connected in parallel with the turbogenerator/motor through a pulse width modulated inverter configured in a first operating mode to supply controlled current from the turbogenerator/motor to a utility electrical power source, and selectively connected to the utility electrical power source through an isolation device, monitoring the utility electrical power source, and automatically disconnecting the protected load from the utility electrical power source while reconfiguring the pulse width modulated inverter in a second operating mode to supply controlled voltage to the protected load when a fault is detected in the utility electrical power source.
