Abstract: An apparatus and method are provided for digital predistortion of an electrical signal to pre-compensate for nonlinear distortions in a nonlinear channel (e.g., a nonlinear channel including a high-power amplifier). The digital predistortion processor includes a nonlinear filter. Filter coefficients are determined using a modified input electrical signal having multiple simultaneous tones, using an iterative process which adapts the modified input electrical signal to reduce levels of intermodulation distortions in a modified output electrical signal.

Abstract: A transparent optical device configured to be used with an underlying device. The underlying device is configured to provide output light. The optical device is configured to transmit light from the underlying device through the optical device. The optical device includes first and second zones. The first zone includes a first plurality of transparent regions formed in the first zone allowing light to pass through from the underlying device. The second zone includes a second plurality of transparent regions formed in the second zone which allow light in the first spectrum to pass through from the underlying device at a different transmission efficiency than the first zone.

Abstract: A method of applying three-phase power to a transformer having limbs including a first limb, a second limb, and a third limb respectively wound with primary windings that include a first winding, a second winding, and a third winding, includes: generating alternating current (AC) voltages (AC voltages) including a first AC voltage, a second AC voltage, and a third AC voltage; initially not applying the AC voltages to the primary windings; monitoring a relative voltage between the first AC voltage and the second AC voltage; and based on results of monitoring, implementing a power-on sequence of sequentially applying various ones of the AC voltages to corresponding ones of the primary windings until all of the AC voltages are applied to all of the primary windings in a manner that balances flux across the limbs during and after the power-on sequence.

Abstract: An apparatus and method are provided for a night vision system including a transparent overlay display that transmit direct-view light representing an intensified image and emits display light representing a display image. The night vision system includes an intensifier with a flat exit face, an overlay display that is flat/planar, and planar, diffractive lens. The direct-view light and the display light exit the overlay display with the same phase curvature (e.g., a flat phase curvature). The planar, diffractive lens induces a spherical phase curvature on the light exiting the overlay display. The phase curvature induced by the planar, diffractive lens matches the phase curvature of a legacy intensifier in which the final element is fiberoptic inverting element with a curved exit face. Accordingly, the combination of the intensifier, overlay display, and planar, diffractive lens can replace the legacy intensifier while maintaining the design specifications of the night vision system.

Abstract: Aspects of the present disclosure relate generally to night-vision systems and more specifically to an integrated micro-display module with a flex circuit. One example illustrated herein includes a method of upgrading a night-vision system. The method may include attaching a flex circuit to an intensifier module, in which the flex circuit includes one or more light detectors and extending beyond a leading edge of the intensifier module. The method may include inserting the intensifier module into a housing and folding the flex circuit to expose the one or more light detectors. The method may further include optically coupling a display unit to an output side of an intensifier module of the night vision system. The display unit may be configured to display graphical content in a field of view together with night-vision images from an output of the intensifier module of the night-vision system.

Abstract: Indicating to a receiver node in a network that the receiver node should begin tracking signal to noise ratio (SNR) of a received signal for a new power and rate (PAR) interval for data sent from a transmitter node. A method includes determining that a new PAR interval is beginning. The method further includes adding an identifier to a data block. The identifier corresponds to the new PAR interval. The method further includes sending the data block from the transmitter node to the receiver node, where the receiver node will use the identifier to determine that a new tracking interval of SNR should be performed for the data block and subsequent data blocks having the identifier.
