  • Patent number: 10982738
    Abstract: A coupling system can include an energy transfer device and a load mitigation system. The energy transfer device can include a shaft, gear, chain or piston-cylinder arrangement to transfer the energy from a power supply to an object to be moved. The load mitigation system can be used to limit or prevent the transfer of forces from the object to the drive unit as a result of external loads being applied to the object. The load mitigation system can be pre-loaded such that external loads on the object having an excessive impulsive or resonant cyclic force greater than the pre-load force on the load mitigation system are reduced and only partially transferred to the energy transfer device and power supply. The load mitigation system can dampen both resonant loads and impulsive impact loads occurring at the object thereby preventing damage and extending life.

  • Patent number: 10953999
    Abstract: An unmanned aerial vehicle docking system can include a docking arm and a docking station. The docking arm can be mounted on the UAV and include a rod with an interface element positioned on top of the rod. The interface element can have charging contacts that are attached to wires that extend down to a charging circuit on the UAV. The docking station can be located separate from the docking arm and have a guidance cone to direct the docking arm to a capture mechanism. Once the interface element is in the capture mechanism, a charging dome is then lowered down onto the top of the interface element to form a circuit between a power source at the docking station and the UAV's battery. Upon completion of the charging process, the charging dome is raised and the capture mechanism releases the interface element of the UAV.

The rotor includes a rotor core, rotor core (RC) magnets, nonmagnetic caps disposed on an outer radial end of each RC magnet, and flux directing (FD) magnets disposed circumferentially between adjacent RC magnets. Each nonmagnetic cap has a radially tapered shape (e.g., trapezoidal). An outer radial end of each cap and an outer radial end of each RC magnet opening define an air gap therebetween. The magnetic flux directions of the RC magnets are circumferentially directed clockwise or counterclockwise, and the flux directions of circumferentially adjacent RC magnets are opposite from each other. The magnetic flux directions of the FD magnets are directed radially inwardly or outwardly, and the flux directions of circumferentially adjacent FD magnets are opposite from each other.

  • Patent number: 10928550
    Abstract: A weather forecasting system has a data processing system that receives weather data from one or more sources and processes such data in conjunction with a weather forecasting algorithm in order to forecast weather for one or more geographic regions. In this regard, the weather data is input into a machine learning algorithm, which applies learned weights and relationships to the inputs in order to calculate at least one score indicating a probability that precipitation or other weather event will occur in the future within a certain time period (e.g., within the next 1 hour or some other unit of time) in one or more geographic regions. For each such geographic region, the weather forecasting logic may also predict the extent to which rain or other precipitation, lightning, or other weather event will occur during the time period.

  • Patent number: 10900822
    Abstract: The present disclosure generally pertains to devices and methods for determining propellant mass based on average measurements irrespective of the fluid orientation in a fuel tank. The device is useful in detecting fuel levels in tanks where the fuel is in motion, for instance in aircraft (i.e., undergoing varying acceleration maneuvers) or spacecraft (i.e., a microgravity environment). The devices and methods can also be used for determining the liquid in a surface tension screen liquid acquisition device (LAD), and particularly, the incipient breakdown as gas bubbles enter or are formed inside the LAD as the screen dries or heat transfer induces vaporization. The same basic electrode configuration can be used to stir the liquid to reduce thermal stratification and condense vapor bubbles.
