Abstract: A universal circuit design environment that designs universal circuits that can be applied to a variety of applications is disclosed. The system cross-references attribute requirements of each contemplated application against components to select application set components that are used to populate the universal design circuit environment for use in a universal circuit design. The set components are capable of satisfying every resolvable attribute requirement of the variety of applications, and the universal circuit may be designed with specialized inputs to set some attributes of the universal circuit. Preferably, the footprint of each set component and universal circuit is preserved between versions to allow for optimized updating between component versions.

Abstract: A fracture interrogation system includes an antenna adapted for placement in a subterranean wellbore and a plurality of pseudoparticles adapted for distribution with a proppant material into hydraulic fractures along the wellbore. The presence of the pseudoparticles in the hydraulic fractures is detectable by the antenna. The pseudoparticles can include a magnetoelastic resonator having a resonant frequency. An interrogation field excites the resonators at the resonant frequency for detection by the antenna. The same or a different antenna can act as the interrogation field source, and the system can be configured to operate in a talk-and-listen mode to better separate the response signal from the interrogation signal. Electromagnetic, mechanical, or acoustic impulses can be used to excite resonators of the pseudoparticles.

Utilizing such techniques, proximities of different portions of an automated aerial vehicle to the ground or other surfaces may be determined (e.g., for detecting issues with an uneven landing area, a sloped ground, etc.).

Abstract: Mechanical vibrations are generated on a frame of an aerial vehicle as a response to operation of the aerial vehicle, such as rotation of motors and/or propellers. Likewise, environmental conditions, such as wind, humidity, etc., may also cause vibrations on the frame of aerial vehicles. These vibrations may be destructive to the aerial vehicle, impact stability of the aerial vehicle, and/or result in audible sounds. Disclosed are systems and methods for measuring and/or predicting the vibrations on the frame of the aerial vehicle, generating anti-vibrations, and outputting those anti-vibrations such that the anti-vibrations modify vibrations on the frame of the aerial vehicle.

Abstract: Unmanned aerial vehicles (“UAVs”) which fly to destinations (e.g., for delivering items) may land on transportation vehicles (e.g., delivery trucks, etc.) for temporary transport. An agreement with the owner of the transportation vehicles (e.g., a shipping carrier) may be made, and the associated transportation vehicles that are available for landings may be identified by markers on the roof or other identification techniques. Different types of communications may be provided as part of a landing process (e.g., a notification regarding a proposed landing may be sent including a request for a confirmation that the proposed landing is acceptable, etc.). The routes of the transportation vehicles may be known and utilized to determine locations where UAVs will land on and take off from the transportation vehicles.
