Abstract: An embodiment of the invention generally relates to a temperature-independent method of determining an engine health parameter, namely stand-off distance, between an eddy current sensor and a conductive element. The method includes receiving a signal from the eddy current sensor and demodulating a waveform from the received signal. The method also includes determining a predetermined set of substantially temperature-independent parameters from the waveform and determining the stand-off distance based on the predetermined set of substantially temperature-independent parameters.

Abstract: A system and method for imaging one or more objects in the presence of unknown phase and amplitude aberrations is described. Multiple images are collected so as to have measurement diversity and processed using a model-based approach to estimate the aberrations. An incoherent imaging model may be constructed to estimate the dependence of the imagery upon the object and the optical system, including the aberrations. A probability density function may then be calculated using the estimated model. Next, a maximum-likelihood estimate may be calculated and optimized, thus yielding a close approximation of the phase and amplitude aberrations. The estimates may then be used to estimate an image of the object or correct the system for future imaging.

Abstract: Software code may include code to receive a first request associated with a discrete problem that is broadcast over a network of cobots. The request may be accepted based on the discrete problem to be solved. The code may also include code to determine whether a utility function associated with the plan to solve the discrete problem meets a threshold. The plan may include a plurality of steps. A report including information related to the chosen plan may be sent to the requesting cobot. Information related to the plan may include information such as the forecasted outcome of the plan. The cobot may then receive permission to implement the chosen plan. The plan may be implemented before any subplans are known or are determined to be possible. In the event that a subplan is required to carry out the plan, then a second request may be broadcast to a plurality of other cobots in the network. One or more of the plurality of other cobots may receive this request and the process may repeat at that cobot as described above. The cobots may be configured in a network of cobots to solve complex problems.

Abstract: Control system for electromechanical arrangements having open-loop instability. The system includes a control unit that processes sensing signals and provides control signals to maintain a movable member, such as a rotor or shaft, in the desired position. The control unit according to the invention includes a unifying plant compensation filter, which isolates the open-loop instability characteristics so that the shaft is treated as a mass having substantially no open-loop structural properties. In magnetic bearings, the open-loop instability is manifested as negative stiffness. The invention isolates the negative stiffness thus providing for better positive stiffness and improved bandwidth. Various filters, summers, and other operators required to carry out the invention are preferably implemented on a programmed processing platform such as a digital signal processor (DSP) or an arrangement of multiple digital signal processors.

Abstract: A bypass cable assembly that protects bypass fibers from one end of a hydrophone assembly to the other, avoiding subjecting the fiber to excessive tow-induced drag loading or the loading incurred during handling of the module. The bypass cable assembly comprises an elastic woven fiber cable with a jacketed optical fiber attached to one side of the cable in a sinusoidal pattern. The cable is attached to a woven fiber protection assembly proximate at each end of the hydrophone assembly. Along a central portion of the cable, the cable transitions to be substantially parallel to the module central axis and is disposed alongside the hydrophone assembly. Elongation of the cable causes the period of the sinusoidal pattern to increase without imparting damaging stress to the optical fiber. The elastic woven fiber cable is periodically attached along the central portion of the cable to positioning tape of an internal strength member.

Abstract: A fiber splice tray for connecting optical fibers between hydrophone modules, allowing each module to be independently assembled. The tray houses the optical fiber in a small space envelope, and allows positioning of a spliced fiber along a straight portion of an internal groove. The internal groove has alternate paths for housing the fiber. The internal groove comprises two opposing parallel sections and two arcs at both ends of the parallel sections, making two continuous looped alternative fiber paths. The internal groove may further comprise two sections that are alternatives to the parallel sections and that cross each other in the middle of the tray. The various alternative fiber paths make it possible to position a splinted optical fiber splice or splice sleeve, which cannot tolerate a bend in the path, in a straight section of the groove.

Abstract: A termination assembly for use in an optical hydrophone module, comprising a module oil seal and an optical fiber seal. The termination assembly is used at the ends of modules and provides a means for filling individual modules with fill fluid. A module oil seal comprises a cylindrical wall defining a cavity, with one end substantially closed and the other end open. An annular face plate on the open end makes a seal dividing a coupling and a clevis. A check valve is mounted to an orifice that passes through the substantially closed end of the module oil seal. Optical fibers pass through the substantially closed end and the optical fiber seal is provided around the optical fiber that passes therethrough. The fiber seal fits snugly in a module oil seal opening. Both components serve to provide a seal that can withstand high pressures and maintain optical fiber integrity.
