  • Patent number: 10611204
    Abstract: Systems and methods for controlling one or more tractive assemblies of a vehicle responsive to a disabling event. A sensor is arranged to detect one or more conditions of a tractive element indicative of the functionality of the tractive element. The sensor generates data corresponding to the detected conditions. The tractive element is coupled to a frame of the vehicle and configured to support a portion of the weight of the vehicle. When the tractive element is determined to not be functioning properly, control signal(s) for an actuator are generated to control a distance between the tractive element and the frame. The control signal(s) cause the tractive element to be effectively raised from a support surface for the vehicle.

  • Patent number: 10472528
    Abstract: A method is used to prepare silver nanoparticles or copper nanoparticles in the form of a silver nanoparticle cellulosic polymeric composite or a copper nanoparticle cellulose polymeric composite, respectively. A cellulosic polymer, organic solvent having a boiling point at atmospheric pressure of 100° C. to 500° C. and a Hansen parameter (?TPolymer) equal to or greater than that of the cellulosic polymer, ascorbic acid, and a nitrogenous base are mixed to form a premix solution. At room temperature or upon heating the premix solution to a temperature of at least 40° C., a solution of reducible silver ions or reducible copper ions is added. The resulting silver or copper nanoparticle composite is cooled, isolated, and re-dispersed in an organic solvent, providing a non-aqueous silver-containing or copper-containing dispersion that can be disposed on a substrate to form an article.

  • Patent number: 10461347
    Abstract: Methods, apparatuses, and systems for real-time monitoring and automated intervention of a power generation. Embodiments may include receiving operating data from components of the power generation system. A potential failure condition for the components may be determined from real-time operating data of the received operating data before an occurrence of the potential failure condition. An alert may be issued in response to determining the real-time operating data indicates a potential failure condition, and instructions for remedying the potential failure condition may be transmitted to the power generation system. An algorithm for determining whether the real-time operating data indicates the potential failure condition may be updated by using preceding operating data in response to detecting the potential failure condition.
