Abstract: To sense the shape of a multicore optical fiber sensor, light reflected in a center and two or more helixed outer cores of the optical fiber sensor is measured, and phases associated with strain in the center and helixed outer cores is tracked along the length of the fiber sensor. Further, a wobble signal indicative of a variation in the spin rate of the fiber sensor is determined. Based on the tracked phases and the wobble signal, the fiber shape is computed.

Abstract: A recovery hook assembly includes a recovery hook fastened to a vehicle frame by a vertically oriented fastener and a horizontally oriented fastener, which connect the recovery hook to the vehicle at three connection points. When the recovery hook is pulled in the forward direction, the recovery hook remains connected to the vehicle to allow the vehicle to be towed. When the recovery hook is pushed in a rearward direction, the recovery hook moves rearward and can break away from the vehicle, thus maintaining crash performance of the vehicle.

Abstract: Methods, systems, and computer-readable storage media for automatic creation of distributed ledger networks. A request to deploy a distributed ledger network is received by an automation framework. The request comprising a configuration file and is associated with a platform type for one or more platforms for deployment of the distributed ledger network. Configuration prerequisites are determined for performing installations of software components on the one or more platforms. In response to installing the software components, the software components are configured and executed to set up an environment for deploying the distributed ledger network by creating a build folder, copying the configuration file and key files for accessing a source code repository into the build folder, and updating the configuration file according to criteria associated with the platform type.

One or more of the plurality of support pads may be adjustable vertically and horizontally relative to the frame through adjustment arms.

Abstract: A multi-core fiber includes multiple optical cores, and for each different core of a set of different cores of the multiple optical cores, a total change in optical length is detected. The total change in optical length represents an accumulation of all changes in optical length for multiple segments of that different core up to a point on the multi-core fiber. A difference is determined between the total changes in optical length for cores of the set of different cores. A twist parameter and/or a bend angle associated with the multi-core fiber at the point on the multi-core fiber is/are determined based on the difference.

Abstract: A passive-intermodulation-mitigating mounting assembly for a fixture, such as can be affixed to a utility or communications monopole can include a first bracket and a second bracket respectively defining a first through hole and a second through hole. In some examples, a mounting plate supports an antenna or a radio. A fastener can extend through the first through hole and the second through hole, for instance to couple the first bracket with the second bracket to attach the mounting assembly to a fixture. The passive-intermodulation-mitigating mounting assembly can include a bushing that can be inserted into a through hole, and the bushing can physically and electrically isolate the fastener from one or more of the brackets. The isolation of the bushing helps inhibit the passive-intermodulation of the mounting assembly when the fastener extends, via the first bushing, through at least one of the through holes.
