A system includes a computing device that generates at least one process script for the modification to a material substrate and at least one pattern script that corresponds to the process script. The computing device also merges the process script with the pattern script and generates a plurality of command signals that are based on the merged process and pattern scripts. An energy source generates a plurality of light beams based on the generated command signal(s). At least one modulating component modulates the generated light beams based on generated command signal(s). A waveform apparatus generates at least one waveform signal to customize the generated light beams based on the generated command signal(s). A motion control apparatus controls at least one parameter of the light beams based on the generated command signal(s).


Under one aspect, a method is provided for processing a received signal, the received signal including a desired signal and an interference signal that spectrally overlaps the desired signal. The method can include obtaining an amplitude of the received signal. The method also can include obtaining an average amplitude of the received signal based on at least one prior amplitude of the received signal. The method also can include subtracting the amplitude from the average amplitude to obtain an amplitude residual. The method also can include, based upon an absolute value of the amplitude residual being less than or equal to a first threshold, inputting the received signal into an interference suppression algorithm so as to generate a first output including the desired signal with reduced contribution from the interference signal.

A deposition assembly generally comprises a first deposition apparatus that is configured to receive a substrate, such as a glass mandrel. The first deposition apparatus is further configured to deposit a plurality of first monolayer molecules onto at least a surface of the substrate to generate a first coating structure on the substrate. A second deposition apparatus is coupled to the first deposition apparatus, and wherein the second deposition apparatus is configured to deposit a plurality of second monolayer molecules onto at least the surface of the substrate such that the second monolayer molecules are diffused through the first coating structure and at least one aperture is filled by at least one of the second monolayer molecules to generate at least one mold release layer on at least the surface of the substrate.


Under one aspect, a method of processing a material includes heating a region of the material with a first energy source; exciting an acoustic wave in the material; and transmitting the acoustic wave through the heated region, the heated region changing at least one property of the acoustic wave. The method also can include detecting the change in at least one property of the acoustic wave; characterizing a temperature of the material in the heated region based on the detected change in at least one property of the acoustic wave; and comparing the characterized temperature of the material in the heated region to a threshold. The method further can include, based on the characterized temperature of the material in the heated region being less than the threshold or being above the threshold for an insufficient amount of time, modifying a property of the heated region with a second energy source.

A spin stabilized aircraft may include a plurality of wings that passively spin stabilize the aircraft, causing the apparatus to move in a direction opposite that of a wind source. The aircraft may also include two or more propulsive arms that actively stabilize the aircraft in absence of wind or a decrease in altitude.

Systems and methods are provided for operating to an initial optimized baseline solution to a multi-objective problem. As the baseline solution is implemented, live (e.g., real-time or near real-time) data associated with one or more parameters may be received and compared to expectations of those parameters with the implementation of the initial optimized solution. If a deviation is detected between the expectation of the time progression of the parameters and live data associated with the parameter, then that deviation may be compared to a threshold. If the deviation meets a threshold condition, then an irregular operation may be declared and a new baseline solution may be implemented. The new baseline solution may be obtained as a re-optimized solution.

An apparatus for forming a flange has a laminate component and a drum supporting the laminate component. A forming tool selectively engages the laminate component. A diaphragm member extends between the drum and the laminate component and selectively engages the forming tool. Movement of the diaphragm member deforms the laminate component away from the drum about an edge of the forming tool, and the laminate component maintains a substantially uniform thickness.

A hybrid-like liquid fuel motor (the motor) may include a port surrounded by a wall. Surrounding the wall are a plurality of chambers and segmented walls to separate the chambers. In some instances, a single helix chamber may surround the wall, and may operate similar to that of a segmental chamber. During operation of the motor, gas flows from one end of the port to another end of the port. As the walls surrounding the port begin to disintegrate, liquid fuel within chambers begins to begin to mix with the flow of gas. As the segmented walls between the chambers begin to disintegrate, liquid from the other chambers begin to mix with the flow of gas, creating a metering of the liquid fuel.

A mechanically simple rotor system is a novel mechanism that collectively drives the pitch of the rotor blades by combining the input from three separate servos. Each servo can be controlled by redundant control systems. This configuration reduces total error caused by any one system and allows the continuation of rotor pitch control in the event of one or more servo or system failures.
