  • Patent number: 12608287
    Abstract: A failure of a head is detected, the head reading from and writing to an affected surface of a disk of a disk drive. The failure prevents the head from writing to the affected surface but does not prevent the head from reading from the affected surface. In response to detecting the failure, a remediation is performed. The remediation involves determining spare capacity blocks on other surfaces of the disk drive different than the affected surface, and copying data from the affected surface to the spare capacity blocks via an internal copy function within the disk drive. The spare capacity blocks in place of the affected surface for data storage and retrieval subsequent to the failure.

  • Patent number: 12545364
    Abstract: A method for shifting a segmented gear may include rotating a gear cluster including a first gear and a coaxial second gear using a power transfer mechanism (e.g., a belt or a chain). The power transfer mechanism defines a plane and is wrapped partially around the first gear. and wherein the first gear has a plurality of gear segments independently movable (e.g., pivotable or translatable) into and out of the plane. A plurality of radially transitionable sliders are rotated in tandem with the first gear, and each of the sliders is operatively coupled to a corresponding one of the gear segments of the first gear. In sequence, each segment of the first gear is moved out of the plane of the power transfer mechanism by urging the slider in a radial direction using a segment actuator, such that the power transfer mechanism wraps at least partially around the second gear.

  • Patent number: 12097929
    Abstract: A gearbox may include a drive spindle and several interconnected gear clusters arranged in a housing. A first of the gear clusters is coaxially fastened to the spindle, and has an outboard gear and an inboard gear. The first gear cluster drives a belt to operate one or more of the other gear clusters, and the inboard gear is physically divided into a plurality of segments. A shifting system for the gearbox includes an actuator configured to urge the segments of the inboard gear of the first gear cluster into and out of the plane of the belt, such that a gear ratio of the gearbox is changeable without displacing the belt out of the plane.

  • Patent number: 11947885
    Abstract: In one aspect, a method includes invoking a signoff tool via a first command from an implementation tool running on a register transfer level (RTL) design, and executing a native command of the signoff tool from within the implementation tool. The native command generates a notification. The method also includes determining whether the RTL design passes a low-power signoff check based on the notification and sending the design for final signoff verification based on the determination that the RTL design passes the low-power signoff checks.

  • Patent number: 11774621
    Abstract: Methods and systems are provided for characterizing fluids in a subterranean formation traversed by a borehole, where NMR data is measured by a downhole NMR tool that is conveyed in the borehole that traverses the formation. The NMR data is processed to derive T1-T2 maps at different depths of the formation. The T1-T2 maps at different depths of the formation can be processed to generate a cluster map of different fluids that are present in the formation, wherein the cluster map is a two-dimensional array of grid points in the T1-T2 domain with each grid point being assigned or classified to a specific fluid. The cluster map of different fluids that are present in the formation can be used to characterize properties of the formation, such as fluid volumes for the different fluids at one or a number of depths.

  • Publication number: 20230243980
    Abstract: Described embodiments generally relate to an electromagnetic survey system configured for geophysical prospecting comprising a structure of booms and rigging that supports and, during normal operation self-levels, a horizontal transmitter coil configured to transmit a magnetic moment. One or more receiver coils, mounted either centrally in the structure, at an extremity of the structure or independent of the structure receive signal from the ground that has been created by the transmitter coil by phenomenon and procedure known to geophysical prospecting practitioners. The structure is supported by a means of locomotion such as shoulders of walking persons, or a towed cart structure.
