摘要： The subject matter of this specification can be embodied in, among other things, a method for removing intermodal distortion that includes receiving a collection of distorted backscattered Rayleigh signals from a collection of modes of an optical fiber, where the collection of distorted backscattered Rayleigh signals are distorted by an intermodal coupling among the collection of modes, receiving a collection of distortion parameters that are descriptive of distortion effects of the intermodal coupling, and determining an undistorted backscattered Rayleigh signal based on the collection of distorted backscattered Rayleigh signals and the collection of distortion parameters.

摘要： Generally, a system for use in a robotic surgical system may be used to determine an attachment state between a tool driver, sterile adapter, and surgical tool of the system. The system may include sensors used to generate attachment data corresponding to the attachment state. The attachment state may be used to control operation of the tool driver and surgical tool. In some variations, one or more of the attachment states may be visually output to an operator using one or more of the tool driver, sterile adapter, and surgical tool. In some variations, the tool driver and surgical tool may include electronic communication devices configured to be in close proximity when the surgical tool is attached to the sterile adapter and tool driver.

摘要： A system or method for a magnetic self-aligning coupling device for a fiber optic cable. The device includes a first end coupling comprising a first magnet and a second magnet. Both magnets include a mating surface and an annular ring defining an axial aperture. The aperture receives a distal end of a segment of fiber optic cable in a tight fit. The fiber optic cable has an exterior sleeve and a fiber core. The fiber core of the first segment and the second segment of the fiber optic cable are axially aligned by magnetic force in the first and second apertures to create a continuous fiber optic path. A method for detecting a security breach of a door using the self-aligning couplings is also described.

摘要： A system for monitoring downhole cement quality in a cased well includes an active acoustic source that generates acoustic waves, a distributed acoustic sensor, and a controller. The distributed acoustic sensor includes an optical fiber disposed on an outer surface of a casing of the cased well; a pulsed laser coupled to the optical fiber and that transmits pulses of laser light along the optical fiber; a sensor that detects light that is backscattered and reflected by the optical fiber; and a processor that controls the pulsed laser, receives signals from the sensor, and converts the signals into acoustic information. The controller receives the acoustic information from the processor and identifies well integrity loss.

摘要： A method for performing a fracturing operation in a subterranean formation of a field. The method includes obtaining, during the fracturing operation, distributed optical fiber data from a downhole sensor of a treatment well in the subterranean formation, and determining, based on the distributed optical fiber data, an active perforation location from a number of pre-determined perforation locations of the treatment well. The active perforation location is a location of fluid flow into the subterranean formation during the fracturing operation. The method further includes generating, based at least on the active perforation location, a fracturing model for the subterranean formation, and performing, based on the fracturing model, modeling of the fracturing operation to generate a modeling result.
