Abstract: A deformable mirror is provided that can include a mirror assembly having a reflective face sheet with a reflective surface on a front side of the reflective face sheet. The mirror assembly can also comprise one or more ferrous materials positioned within and making up or forming, in part, the mirror assembly. The deformable mirror can also include one or more electromagnets operable to generate a magnetic field that acts on the ferrous materials to deform the reflective face sheet.

Abstract: A Permanent Magnet Synchronous Motor (PMSM) includes a hollow cylindrical stator with stator windings and a magnetic rotor having M pole pairs arranged to rotate around a rotational axis in the stator by a rotor shaft. The stator windings are energized to generate a magnetic rotational field in dependence upon the rotational position of the magnetic rotor. Two or more analog magnetic flux sensors are positioned within the hollow cylindrical stator and arranged concentrically with respect to the rotational axis around the stator at a constant mechanical angle equal to a constant electrical angle divided by M relative to each other. The magnetic flux sensors are spaced directly from the magnetic rotor by a radial gap (X) in such a way that the magnetic flux of the magnetic rotor impinges on the analog magnetic flux sensors without obstruction to output two or more sinusoidal signals with phases separated by the constant electrical angle that can be evaluated to determine the rotational position of the magnetic rotor. Sensor integration eliminates the additional sense magnet, Hall sensors and CCA positioned external to the motor housing to provide a smaller motor package at lower cost. Integration also facilitates the use of the PMSM in high-temperature or high-shock (high g) environments such as gun-launched guided projectiles or hypersonic missiles.

Abstract: A system includes multiple electrical nodes connected in series to a primary power source via transmission lines. Each node includes a power converter that can receive first power from the primary power source or another upstream node. The power converter can change a voltage level and/or a frequency of the first power. Each node also includes a high-speed synchronous rotating machine (HSRM), which includes an inertial storage flywheel, a rotating excitation assembly, stator windings, and a synchronous motor coupled to an induction generator. The HSRM can boost a voltage level between an input and output to compensate for a voltage drop of the first power. At least one of the nodes further includes an inductive power coupler to electrically couple the node to a mobile power source that provides second power to the node and receives a portion of the first power from the node using contactless inductive power transfer. The system includes a combination of AC and DC power transmission techniques and associated bidirectional power converters.

Abstract: A system includes a signal seeder configured to generate a pulsed seed signal, where the signal seeder includes a master oscillator configured to generate an optical signal at a first wavelength. The system also includes a series of optical preamplifiers collectively configured to amplify the pulsed seed signal and generate an amplified signal. The system further includes a Raman fiber amplifier configured to amplify the amplified signal and generate a Raman-shifted amplified signal. The Raman fiber amplifier is configured to shift a wavelength of the amplified signal to a second wavelength different than the first wavelength during generation of the Raman-shifted amplified signal.

Abstract: Methods and apparatus for monostatic pulsed time-resolved wide-field-of-view underwater laser imaging. In embodiments, a rotatable optical assembly consisting of a single pyramid mirror and optical ports for each facet is used to both direct a transmitted pulsed laser beam to a target and focus the return signal to a high dynamic range detector, such as a photomultiplier tube, The detector output signal is sampled by a high-speed digitizer and can be processed to generate three-dimensional images.

Abstract: A method includes receiving electromagnetic signals containing pulses. The method also includes converting the pulses contained in the electromagnetic signals into an electrical signal that identifies at least some of leading or trailing edges of the pulses. The method further includes repeatedly (i) accumulating the electrical signal to generate a voltage using an integrating circuit and (ii) resetting the integrating circuit in response to the voltage of the integrating circuit meeting or exceeding a threshold voltage. In addition, the method includes providing a count value identifying a number of times that the voltage of the integrating circuit meets or exceeds the threshold voltage. Each time the voltage of the integrating circuit meets or exceeds the threshold voltage is representative of a specific number of pulses received in the electromagnetic signals.

Abstract: Circuit and method for electro-optic modulation of an RF signal to produce a single-sideband reduced-carrier phase-shifted (SSB-RC-PS) modulated signal includes: receiving an optical carrier signal; receiving the RF signal; modulating the RF signal with a first portion of the optical carrier to produce a single sideband (SSB) modulated signal; amplitude and phase modulating a second portion of the optical carrier signal and combining with the modulated signal to produce a first combined signal, the amplitude modulation and phase modulation of the second portion of the optical carrier signal are dynamically controlled to directly match the amplitude and inversely match the phase of the modulated signal; and amplitude modulating and phase modulating a third portion of the optical carrier signal and combining third portion with the first combined signal to produce the second combined signal, the product of which is a single sideband reduced carrier phase shifted (SSB-RC-PS) modulated signal.

Abstract: A method includes obtaining an image of a scene and identifying one or more statistics associated with each of multiple processing regions within the image, where each processing region represents a portion of the image. The method also includes generating a probability of each of the processing regions containing at least one object of interest based on the statistics associated with the processing regions. The method further includes allocating multiple processing windows to one or more of the processing regions based on the probabilities, where the processing windows are smaller than the processing regions. In addition, the method includes performing object detection within the allocated processing windows.
