  • Publication number: 20210083468
    Abstract: A detection scheme for temporary overvoltages and/or ground fault overvoltages in electric power systems is described. Current passing through a surge arrestor component of the power system is monitored. An algorithm for identifying one or more frequency components of the measured current signal is performed to screen out unwanted harmonics. In some embodiments, this is a frequency domain analysis. The frequency component(s) of the current signal is then compared to a calculated pickup current or pickup voltage of the system to determine if system protection steps should be undertaken.

  • Publication number: 20210050628
    Abstract: A method of prolonging service life of an energy storage device such as a lithium-ion battery includes temporarily operating the battery at an elevated current density. Cycling of lithium-ion batteries at regular current densities results in the generation of lithium-metal dendrites at the surface of the anode, particularly in batteries where the anode is lithium metal. The lithium metal dendrites pose a threat to damage other components of the battery, such as separators, as well as causing an electrical short. Operating the battery in bursts at the elevated current density results in self-heating at the anode surface that merges adjacent lithium-metal dendrites and an overall smoothing of the anode surface. This method is also applicable to other alkali-metal-based batteries and chemistries.

  • Patent number: 10907669
    Abstract: Methods and systems for controlling a fluid flow field near a surface are disclosed. In some embodiments, the system includes an array of oscillating bodies disposed on the surface to provide physical modification to the flow field. Fluid jets are also emitted from an outlet in the oscillating body to provide virtual modification of the flow field through momentum addition. Fluid jet sources, including synthetic jet generators such as piezoelectric drivers and sources of compressed fluids such as air or water, are positioned to be in fluid communication with the outlet at intervals during the oscillation of the oscillating body. Controlling the oscillation amplitude and frequency of the body, as well as the location of oscillating body outlets and frequency of fluid jet emission, have advantageous effects for the surface such as improved heat transfer properties and reduction in structural vibration and noise.

  • Patent number: 10896739
    Abstract: Method, system and computer program product are provided for estimating a circadian phase of a subject by: obtaining a sensed biological signal for the subject; and using, by one or more processors, adaptive frequency tracking to adaptively estimate the circadian phase of the subject from the sensed biological signal. Circadian phase estimation may be accelerated by providing a feedback loop for the adaptive frequency tracking, which utilizes, in part, a circadian phase model in automatically ascertaining a phase correction for the adaptive frequency tracking. The circadian phase estimation may be used in automatically constructing a light-based circadian rhythm model for the subject using a linear parameter-varying (LPV) formulation, and once constructed, the circadian rhythm model for the subject may be used to provide light-based circadian rhythm regulation.

  • Publication number: 20200405649
    Abstract: Compositions of the present disclosure include a first dCas9-FokI-sgRNA complex and a second dCas9-FokI-sgRNA complex. The first sgRNA is configured to target a first side of a genomic fusion site and the second sgRNA is configured to target a second side of the genomic fusion site. The first and second complexes only cut DNA upon dimerization. Thus, upon binding of both first dCas9-FokI-sgRNA complex and second dCas9-FokI-sgRNA complex, the dimer is produced and DNA cleavage proceeds at the genomic fusion site. The dCas9-FokI-sgRNA complexes are loaded on a folded-DNA shell for transport across the cellular membrane. The shell has a viral-mimic structure that maximizes cell entry, is non-cytotoxic, has low-to-nonimmunogenicity, and provides excellent capacity to enclose and protect the complexes. These systems exhibit both cellular (via the shell) and molecular (via the complexes) specificity, significantly reducing off-target activity and the associated harmful side-effects.

  • Patent number: 10864227
    Abstract: A heparin structure with increased anticoagulant activity and method of making the same are disclosed. A heparin sample is provided and treated with a heparan sulfate sulfotransferase in an enzymatic reaction to add sulfuryl groups from a sulfuryl group source to the heparin sample, resulting in a heparin structure having above about 8% more 3-O-sulfo groups relative to wild-type bovine intestinal heparin. The added sulfuryl groups modify the heparin structure and increase the sample's binding to antithrombin III and its anticoagulant activity to be more similar and a viable alternative to porcine intestinal heparin. The modified heparin exhibits an anti-FXa activity and an anti-FIIa activity greater than about 180 U/mg, and a ratio of the anti-FXa activity to the anti-FIIa activity of about 0.9 to about 1.1, consistent with U.S. Pharmacopeia (USP) heparin activity specifications.
