摘要： An unmanned aerial system (UAS) is disclosed. In embodiments, the UAS includes an unmanned aerial vehicle (UAV), and a controller communicatively coupled to the UAV. In embodiments, the UAS controller may be configured to: acquire a command and control (C2) link quality model for a planned route; generate one or more control signals configured to cause the UAV to perform a monitored flight along a planned route; acquire actual C2 link quality data during the monitored flight along the planned route; compare the actual C2 link quality data to the C2 link quality model; identify a C2 link quality deviation between the actual C2 link quality and the C2 link quality model; and generate one or more control signals configured to cause the UAV to perform one or more prescribed flight plan maneuvers if the identified C2 link quality deviation (ΔC2LQ) exceeds a threshold deviation value (C2thresh).

摘要： A galley structure for an aircraft cabin includes double-depth cart bays capable of stowing an outer full-size cart in front of an inner fell-size cart. An extraction and retention (E&R) system is mounted to a sidewall of the double-depth cart bay and includes a stowable retainer arm and fixed extractor arm coupled to and articulable via an extraction handle that may be pulled or pushed out of or toward the cart bay. When the outer cart is removed, the inner cart can be brought forward for extraction via the extractor arm (the inner cart extractable once the retainer arm is stowed) and returned to its inner stowed position via the retainer arm (in both cases, by pulling or pushing the extraction handle). The extraction handle includes a retainer actuator for stowing or deploying the retainer arm as needed.

摘要： An exterior elevated assembly with a walking surface is described which has features for facilitating inspection of the interior support frame of the assembly. The assembly includes a support frame for the walking surface, which defines an interior space and a soffit covering an underside of the support frame. The soffit provided with an opening. A vent panel is provided for covering the opening and a vent panel retention mechanism is provided for reversibly holding the vent panel in place over the opening. Methods and kits for installing a vent panel in a soffit of an exterior elevated assembly with a walking surface are also described.

摘要： A system and method for adjusting polarization of a loop antenna includes a loop antenna with a high impedance autotransformer. The high impedance autotransformer may be connected to the middle of the horizontal leg of a delta loop or the middle of either horizontal leg of a square loop. The feed-point impedance of the loop antenna may be adjusted between about one hundred ohms and ten thousand ohms. The feed-point impedance is adjusted automatically to maximize signal gain. A neural network may be trained to set the feed-point impedance based on environmental conditions and observed periodicity, with a feedback loop based on actual gain or signal strength.

摘要： A touchscreen device utilizes digital scan to resolve a touch location with high precision. The touchscreen device includes touchells of about 3.175 mm by 3.175 mm (0.125 inches by 0.125 inches). An integrated circuit detects contacts in the touchells that resolve to touches on the touchscreen, and communicates those touches to a micro-controller via a serial bus. Silver epoxy interconnects for the tracks are reduced or eliminated. Multiple touchscreens having distinct touchell networks may be disposed to create a larger touchscreen area. Similarly, a single touchscreen may be divided quadrants, each with a distinct touchell network.

摘要： A spectroscopic metrology system includes a spectroscopic metrology tool and a controller. The controller generates a model of a multilayer grating including two or more layers, the model including geometric parameters indicative of a geometry of a test layer of the multilayer grating and dispersion parameters indicative of a dispersion of the test layer. The controller further receives a spectroscopic signal of a fabricated multilayer grating corresponding to the modeled multilayer grating from the spectroscopic metrology tool. The controller further determines values of the one or more parameters of the modeled multilayer grating providing a simulated spectroscopic signal corresponding to the measured spectroscopic signal within a selected tolerance. The controller further predicts a bandgap of the test layer of the fabricated multilayer grating based on the determined values of the one or more parameters of the test layer of the fabricated structure.

摘要： An antenna system may include an antenna array configured to receive one or more signals. In embodiments, the antenna system further includes one or more signal processors configured to: determine a beamforming weight vector (Wbf) for the antenna array; determine a first seeding weight vector (Wseed1) for the antenna array, wherein the first seeding weight vector (Wseed1) comprises a first nulling weight vector (Wnul1) or a second beamforming weight vector (Wbf); determine a first nullforming adjustment factor (η1) for the antenna array; calculate a first nullforming weight vector (Wnf1) based on at least the beamforming weight vector (Wbf), the first seeding weight vector (Wseed1) and the first nullforming adjustment factor (η1); and form a first antenna pattern based on the first nullforming weight vector (Wnf1) to generate a first antenna electronics (AE) output signal, wherein the first antenna pattern generates a first set of one or more nulls.
