摘要： A robotic gripper for rigidly grasping a section of a Marman ring of a satellite, the robotic gripper having an outboard jaw which interfaces to an outer diameter side of the Marman ring, a inboard jaw which interfaces to an inner diameter side of the Marman ring, and a palm which interfaces to a separation surface of the Marman ring. The jaws, when grasping the section of the Marman ring, execute a two-stage motion comprising a first movement toward the opposing jaw in a direction parallel to the palm, and a second movement of drawing the Marman ring down against the palm or other suitable surface in order to fully rigidize the grasp.

摘要： An autonomous emergency flight management system may find safe and clear landing sites for unmanned aerial systems (UASs) in emergency situations. Emergency flight management software may reside on an onboard computing system. The computing system may continuously look at internal databases and input from other systems (e.g., a global positioning system (GPS), camera, compass, radar, sonar, etc.), depending on what is available. The emergency flight management system may make decisions on its own without human intervention. For instance, a database may provide some local likely candidates for landing sites. Information associated with the candidates may include latitude, longitude, altitude for top of a building, etc. Position updates may be continuously provided from an autopilot or other suitable system.

摘要： Method and systems are disclosed for training state-classifiers for classification of cognitive state. A set of multimodal signals indicating physiological responses of an operator are sampled over a time period. A depiction of operation by the operator during the time period is displayed. In response to user input selecting a cognitive state for a portion of the time period, the one or more state-classifiers are trained. In training the state-classifiers, the set of multimodal signals sampled in the portion of the time period are used as input to the one or more state-classifiers and the selected one of the set of cognitive states is used as a target result to be indicated by the one or more state-classifiers.

摘要： A cutting mechanism includes electrodes that are utilized to cut or score a non-conductive outer material of a filament or sheet. The electrodes contact a conductive reinforcing material of the filament or sheet to complete an electric circuit. Electric current flows through and heats the conductive material to oxidize or otherwise separate/cut the conductive material and any remaining non-conductive material.

摘要： Various embodiments provide rollable and deployable composite booms that may be used in a wide range of applications both for space and terrestrial structural solutions. Various embodiment composite booms may be bistable, i.e. having a stable strain energy minimum in the coiled configuration as well as the in the deployed configuration. In various embodiments, a boom may be fabricated by aligning two independent tape-springs front-to-front encircled by a durable seamless polymer sleeve. The durable seamless polymer sleeve may allow the two tape-springs to slide past each other during the coiling/deployment process so as to reduce, e.g., minimize, shear and its derived problems.

摘要： An integrated hybrid crystal Light Emitting Diode (“LED”) display device that may emit red, green, and blue colors on a single wafer. The various embodiments may provide double-sided hetero crystal growth with hexagonal wurtzite III-Nitride compound semiconductor on one side of (0001) c-plane sapphire media and cubic zinc-blended III-V or II-VI compound semiconductor on the opposite side of c-plane sapphire media. The c-plane sapphire media may be a bulk single crystalline c-plane sapphire wafer, a thin free standing c-plane sapphire layer, or crack-and-bonded c-plane sapphire layer on any substrate. The bandgap energies and lattice constants of the compound semiconductor alloys may be changed by mixing different amounts of ingredients of the same group into the compound semiconductor. The bandgap energy and lattice constant may be engineered by changing the alloy composition within the cubic group IV, group III-V, and group II-VI semiconductors and within the hexagonal III-Nitrides.

摘要： Systems and methods for measuring phase dynamics and other properties (e.g. intracranial pressure) are disclosed. For example, the system may generate a reference waveform and a measurement waveform using digital synthesizers, each waveform having an identical constant frequency but also a relative phase shift. Next, system may send a tone-burst, via a transducer, into a sample (e.g. a skull or a bonded material), and then receive a reflected tone-burst in response. Then, a phase difference between the received tone-burst and the measurement waveform may be determined with a linear phase detector. Next, the phase shift of the measurement waveform may be adjusted, by the determined phase difference, such that there is no longer any phase difference between the received tone-burst and the adjusted measurement waveform generated by the appropriate digital synthesizer. A similar adjustment may occur after subsequent tone-bursts, allowing accurate monitoring of continuously variable phase relationships.
摘要翻译： 公开了用于测量相位动力学和其他性质（例如颅内压）的系统和方法。 例如，系统可以使用数字合成器产生参考波形和测量波形，每个波形具有相同的恒定频率，但是也可以是相对相移。 接下来，系统可以经由换能器将音调脉冲串发送到样本（例如颅骨或粘合材料）中，然后响应地接收反射的音调脉冲串。 然后，可以用线性相位检测器来确定接收的音调脉冲串与测量波形之间的相位差。 接下来，可以通过所确定的相位差来调整测量波形的相移，使得接收的音调脉冲串与由适当的数字合成器产生的经调整的测量波形之间不再有任何相位差。 在随后的音调突发之后可能发生类似的调整，允许精确地监视连续可变的相位关系。

摘要： A wireless chemical sensor includes an electrical conductor and a material separated therefrom by an electric insulator. The electrical conductor is an unconnected open-circuit shaped for storage of an electric field and a magnetic field. In the presence of a time-varying magnetic field, the first electrical conductor resonates to generate harmonic electric and magnetic field responses. The material is positioned at a location lying within at least one of the electric and magnetic field responses so-generated. The material changes in electrical conductivity in the presence of a chemical-of-interest.
