  • Publication number: 20190381995
    Abstract: Methods and systems are described for conserving energy used by an energy consuming device. In certain embodiments, an energy conservation system can be configured to deliver energy to the energy consuming device for a period, followed by a period where energy delivery is dampened and/or cut. By cycling the delivery of energy in this fashion, the energy conservation can achieve a pulsed efficiency.

  • Patent number: 10458863
    Abstract: Virtual sensors can be used to monitor the loads on the system in determining damage accumulation, remaining useful life or retirement time of the components. A virtual sensor is a mathematical construct to infer a desired system measurement (e.g. a structural load) from readily available system state parameters (e.g. speed, weight, load factors, control settings, etc.). The accuracy of the virtual sensor depends upon the mapping between the desired measurement and the state parameters. A hybrid load monitoring system and method includes one or more direct or physical sensor measurements in addition to the plurality of virtual sensors. Signals from the physical sensors are included as an input (as opposed to an output) to the mapping between system state parameters and the various target sensor feature amplitudes.

    Abstract: A system, method, and computer program for detecting and isolating structural faults is provided. To detect and isolate structural faults, a plurality of sensed features that corresponds to sensor data from the monitoring sub-system and a plurality of estimated features that corresponds to the plurality of sensed features can be generated. Further, the plurality of sensed features and the plurality of estimated features can be compared to produce a plurality of residuals. From the plurality of residuals, at least one structural fault within the vehicle are determined and isolated for further use of maintenance decision support.

  • Patent number: 9521842
    Abstract: The use of poly(oxybutylene)-poly(oxyethylene)-poly(oxybutylene) block copolymers in pharmaceutical compositions useful for modifying the surfaces of contact lenses and other medical devices is disclosed. The present invention is based in-part on a discovery that this class of compounds is particularly efficient in wetting hydrophobic surfaces, such as the surfaces of silicone hydrogel contact lenses and other types of ophthalmic lenses, but do not induce foaming when used in conjunction with a peroxide-based contact lens disinfection regimen. Such compounds may also be useful for cleaning purposes. The use of the compounds as surfactants in peroxide-based compositions for disinfecting contact lenses therefore represents a preferred embodiment of the present invention.

  • Publication number: 20140364422
    Abstract: The present invention is an aqueous pharmaceutical composition that includes an ionized therapeutic agent, an ionic component and guar gum. The guar gum is present in the composition a concentration sufficient to limit interactions between the ionized therapeutic agent and the ionic component thereby imparting stability to the composition. The composition is preferably at or near physiologic pH. The aqueous pharmaceutical composition has been found particularly useful as an aqueous ophthalmic, otic or nasal composition. The pharmaceutical composition, due to its characteristics, is particularly suitable as an ophthalmic composition.
