In some embodiments, the autonomous system may include one or more tethers connected to a heavy object, each tether position and location controlled by one or more actuators.

Abstract: An intelligent electric meter digital manufacturing platform based on intelligent manufacturing includes: an electric push rod fixedly disposed in a frame and a testing machine disposed on the electric push rod. The testing machine includes a box fixedly disposed on a telescopic shaft of the electric push rod and a testing component disposed in the box. A first pulley drives two ends of a pulling rope to move from a middle end of a side wall of the pulling rope through driving of a servo motor. This makes an end of the pulling rope pull a testing probe to move upwards, the other end of the pulling rope pull the other testing probe to move downwards, allowing it move to a bottom of the box. This design avoids affecting testing efficiency due to the need to replace or maintain the testing probes, facilitating subsequent testing of an intelligent electric meter.

Abstract: Described herein are concepts, system and techniques which provide a means to construct robust high-field superconducting magnets using simple fabrication techniques and modular components that scale well toward commercialization. The resulting magnet assembly—which utilizes non-insulated, high temperature superconducting tapes (HTS) and provides for optimized coolant pathways—is inherently strong structurally, which enables maximum utilization of the high magnetic fields available with HTS technology. In addition, the concepts described herein provide for control of quench-induced current distributions within the tape stack and surrounding superstructure to safely dissipate quench energy, while at the same time obtaining acceptable magnet charge time. The net result is a structurally and thermally robust, high-field magnet assembly that is passively protected against quench fault conditions.

Abstract: Synells are created by encapsulating components and iteratively optimizing each synell for a desired trait. Each synell is tested during each interation. Failed synells are discarded. Additional synell components are added during each iteration, with iterative optimization being repeated until synells having the trait are created. A method for synell reproduction includes creating a synell having a desired trait, determining a recipe for the synell, digitizing the recipe, and transmitting the digitized recipe to another location. The recipe is reconstituted at the other location and the synell is reproduced using the recipe. On-demand biosynthesis of synells includes generating droplets containing different synell components within a microfluidic device, fusing them into combinations, and storing them until a request for a synell having a particular trait is received.
