System and method for hijacking inodes based on replication operations received in an arbitrary order
A system and method for hijacking inodes based on replication operations received in an arbitrary order is used to assist a data replication operation from a source storage system to a destination storage system. The source storage system generates a set of replication operations as part of a replication process and transmits the replication operations in an arbitrary order.

If an inconsistency exists, the system hijacks the destination inode by replacing the destination inode's metadata with data determined based on the replication operation. The system may also delete metadata from the inode and/or initialize metadata to default values if the metadata was not replaced based on the replication operation. The system then waits for a second replication operation that contains the remaining metadata and replaces the metadata based on the second replication operation. In addition, data blocks associated with the previous version of the inode are freed. |

Lidar resistant to interference and hacking
Lidar uses light to sense the range to an object. It can be used as a sensor, e.g., for autonomous vehicle navigation, or to generate detailed maps of terrain.

Incoherent (time of flight (TOF)) lidars can also be spoofed or hacked. And both coherent and incoherent lidars can be jammed. Modulating the lidar source makes the lidar more resistant to interference, jamming and hacking. In a TOF lidar, each transmitted pulse is modulated in a prearranged or predetermined fashion. A processor in the receiver distinguishes true returns from actual returns based on the modulation or encoding of the transmitted pulses. If the modulation is present, the return signal considered genuine. If the modulation is not present, it is deemed fake. |

A rotatable element for an earth-boring tool in a subterranean borehole includes a rotatable element and a stationary element. The rotatable element and stationary element include a seal arrangement between the rotatable element and the stationary element. The seal arrangement encloses a volume that remains substantially constant as the rotatable element moves relative to the stationary element. |

Dual rod directional drilling system
A coupler includes a main body that has an inner bore. The inner bore has a non-circular profile and a longitudinal axis. The coupler includes a cross aperture disposed in the main body. The cross aperture has an axis that is nonintersecting with the longitudinal axis of the main body. The coupler also includes a sleeve that is positioned around an exterior surface of the main body. The sleeve has at least one drilling fluid flow passage. |

Motor assemblies for architectural coverings
Example motor assemblies for architectural coverings are described herein. An example motor assembly includes a motor, a first switch to trigger the motor to retract an architectural covering, a second switch to trigger the motor to extend the architectural covering, and an actuator positioned to activate the first switch when the actuator is rotated in a first direction and to activate the second switch when the actuator is rotated in a second direction. Also described herein are example lever actuators for motor assemblies of architectural coverings. An example lever actuator detaches from the motor assembly to prevent excess force on the motor assembly that could otherwise detrimentally affect the motor assembly. |
