Abstract: Systems and methods for aircraft refueling with sun glare prevention. One embodiment is a method that includes calculating a future time to position a receiver aircraft via an optical sensor with respect to a supply aircraft for an aerial fuel transfer, and calculating a sun position relative to the position of the receiver aircraft for the future time. The method also includes determining that the optical sensor of the receiver aircraft is susceptible to solar interference for the future time based on the sun position relative to the position of the receiver aircraft. The method further includes generating a request for the supply aircraft to move to an alternate position for the future time, and positioning the receiver aircraft via the optical sensor at the future time with respect to the alternate position of the supply aircraft for the aerial fuel transfer.

Abstract: Embodiments described herein provide for electrically reconfigurable deposition masks. One embodiment is a deposition mask that includes a plurality of electrical elements. Each of the electrical elements has an opening between a top surface and a bottom surface that constricts based on an electrical signal. A plurality of top surfaces of the electrical elements defines a top surface of the mask, and a plurality of bottom surface of the electrical elements defines a bottom surface of the mask.

Abstract: A chassis system includes a body, a lid, a cavity, a backplane, and an electrically conductive connector. The lid is removably attached to the body such that when the lid is attached to the body a cavity within the body is completely enclosed by the body and the attached lid. The lid and the body are made of at least one material that does not allow electromagnetic waves to enter the cavity. The backplane is attached to the body or the lid. The electrically conductive connector is attached to the body or lid. The connector is in wired or wireless communication with the backplane for allowing electricity or data to flow between the electrically conductive connector and the backplane. The chassis system may be used to environmentally protect one or more electronic modules inserted into the cavity of the chassis system.

Abstract: A frequency reconfigurable antenna may include at least two antenna segments and a photonic crystal positioned between the at least two antenna segments. The photonic crystal may selectably electrically connect or isolate the at least two antenna segments with respect to each other based on a conductive state of the photonic crystal.
