摘要: The present invention proposes an automatic dependent surveillance broadcast (ADS-B) architecture and process, in which priority aircraft and ADS-B IN and radar traffic information are included in the transmission of data through the telemetry communications to a remote ground control station. The present invention further proposes methods for displaying general aviation traffic information in three and/or four dimension trajectories using an industry standard Earth browser for increased situation awareness and enhanced visual acquisition of traffic for conflict detection. The present invention enable the applications of enhanced visual acquisition of traffic, traffic alerts, and en-route and terminal surveillance used to augment pilot situational awareness through ADS-B IN display and information in three or four dimensions for self-separation awareness.

摘要: In an embodiment, a relative deflection detector may include at least two structural arcs, and a predetermined number of means for measuring position capable of determining the relative deflection in a first component. The at least two structural arcs may be for example, comprised of a first and second structural arc whereby the first and second structural arcs are attached to the first component at respective first and second predetermined locations and whereby each arc is comprised of a respective sequence of indicators, such as, for example, codes inscribed on the outer circumference of each arc. The first and second structural arcs may be positioned in concentric and coplanar relationship with each other. The predetermined number of sensors may be comprised of a first and second optical encoder sensor each positioned in proximate and coplanar relationship with the first and second structural arcs so as to read the first sequence of codes, second sequence of codes, or both, and thereby detect positions of each structural arc (e.g., a first position corresponding to the first structural arc and a second position corresponding to the second structural arc). The first and second positions may be used to calculate and thereby determine a relative deflection of the first component.

摘要: A passive beamforming rectenna includes a plurality of antennas, a plurality of terminal port rectifying circuits, and a beamforming network. The beamforming network includes (a) a plurality of antenna ports connecting to the plurality of antennas, and (b) a plurality of terminal ports connecting to the plurality of terminal port rectifying circuits. The beamforming network further includes a microwave lens or any of a variety of other structures. The beamforming rectenna is characterized by a plurality of radiation distribution patterns. Electromagnetic power is received through the plurality of antennas. The beamforming network directs the received electromagnetic power, in substantial portion, to a subset of the plurality of terminal ports associated with particular radiation distribution patterns whose amplitudes, in the direction from which the electromagnetic power was received, are large relative to the amplitudes, in the same direction, of other radiation distribution patterns associated with other terminal ports.

摘要: A method of mapping pixel locations of a detector array includes measuring a location on the detector array, initiating a frame readout of the detector array, measuring a location of one or more metrology targets on the detector array, analyzing the frame readout to identify a pixel at the location on the detector array, and defining a location of the identified pixel with respect to the location of the one or more metrology targets. Subsequent measurement of the metrology targets alone by another metrology system allows one to infer the six degree of freedom alignment of the detector array in space.

摘要: The present invention relates to a space-based instrument which provides continuous coronal electron temperature and velocity images, for a predetermined period of time, thereby improving the understanding of coronal evolution and how the solar wind and Coronal Mass Ejection transients evolve from the low solar atmosphere through the heliosphere for an entire solar rotation. Specifically, the present invention relates to using a 6U spherical occulter coronagraph CubeSat, and a relative navigational system (RNS) that controls the position of the spacecraft relative to the occulting sphere. The present invention innovatively deploys a free-flying spherical occulter, and after deployment, the actively controlled CubeSat will provide an inertial formation flying with the spherical occulter and Sun.

摘要: A system includes a glove, sensors, actuator assemblies, and controller. The sensors include load sensors which measure an actual grasping force and attitude sensors which determine a glove attitude. The actuator assembly provides a grasp assist force to the glove. Respective locations of work cells in the work environment and permitted work tasks for each work cell are programmed into the controller. The controller detects the glove location and attitude. A work task is selected by the controller for the location. The controller calculates a required grasp assist force using measured actual grasping forces from the load sensors. The required grasp assist force is applied via the glove using the actuator assembly to thereby assist the operator in performing the identified work task.
