  • Patent number: 9543575
    Abstract: A silicon-based anode comprising silicon, a carbon coating that coats the surface of the silicon, a polyvinyl acid that binds to at least a portion of the silicon, and vinylene carbonate that seals the interface between the silicon and the polyvinyl acid. Because of its properties, polyvinyl acid binders offer improved anode stability, tunable properties, and many other attractive attributes for silicon-based anodes, which enable the anode to withstand silicon cycles of expansion and contraction during charging and discharging.

  • Patent number: 9536725
    Abstract: A liquid sampling, atmospheric pressure, glow discharge (LS-APGD) device as well as systems that incorporate the device and methods for using the device and systems are described. The LS-APGD includes a hollow capillary for delivering an electrolyte solution to a glow discharge space. The device also includes a counter electrode in the form of a second hollow capillary that can deliver the analyte into the glow discharge space. A voltage across the electrolyte solution and the counter electrode creates the microplasma within the glow discharge space that interacts with the analyte to move it to a higher energy state (vaporization, excitation, and/or ionization of the analyte).

  • Patent number: 9507367
    Abstract: A dynamic stochastic optimal power flow (DSOPF) control system is described for performing multi-objective optimal control capability in complex electrical power systems. The DSOPF system and method replaces the traditional adaptive critic designs (ACDs) and secondary voltage control, and provides a coordinated AC power flow control solution to the smart grid operation in an environment with high short-term uncertainty and variability. The DSOPF system and method is used to provide nonlinear optimal control, where the control objective is explicitly formulated to incorporate power system economy, stability and security considerations. The system and method dynamically drives a power system to its optimal operating point by continuously adjusting the steady-state set points sent by a traditional optimal power flow algorithm.

  • Patent number: 9506166
    Abstract: Disclosed are heterogeneous crystals for use in a laser cavity and methods of forming the crystals. A crystal can be a monolithic crystal containing a garnet-based activator region and a garnet-based Q-switch. Disclosed methods include hydrothermal growth techniques for the growth of differing epitaxial layers on a host. A YAG host material can be doped in one region with a suitable activator ion for lasing and can be formed with another region that is doped with a saturable absorber to form the Q-switch. Regions can be formed with controlled thickness in conjunction. Following formation, a heterogeneous crystal can be cut, polished and coated with mirror films at each end for use in a laser cavity to provide short pulses of high power emissions using high frequency pulse modes.

  • Patent number: 9383292
    Abstract: A fluidic probe comprising a plurality of oriented fibers with individual fibers having nano-pores in the fiber bodies, the oriented fibers being twisted together, wherein the twisted oriented fibers form micro-pores between the individual fibers, is disclosed. The fluidic probe exhibits excellent flexibility, deployability and absorptive capacity. The enhanced absorptive capacity is due to the fluid absorption via capillary action of the nano-pores and fluid transport via the micro-pores. The probes can also be formed so as to be remotely controlled by electromagnetic fields and thus be used in a hands-free fashion. With these probes, the paradigm of a stationary microfluidic platform can be shifted to include flexible structures that can include multiple microfluidic sensors in a single fibrous probe.

  • Publication number: 20160158160
    Abstract: The present invention is a bioactive, nanofibrous material construct which is manufactured using a unique electrospinning perfusion methodology. One embodiment provides a nanofibrous biocomposite material formed as a discrete textile fabric from a prepared liquid admixture of (i) a non-biodegradable durable synthetic polymer; (ii) a biologically active agent; and (iii) a liquid organic carrier. These biologically-active agents are chemical compounds which retain their recognized biological activity both before and after becoming non-permanently bound to the formed textile material; and will become subsequently released in-situ as discrete freely mobile agents front the fabric upon uptake of water from the ambient environment.

  • Patent number: 9291383
    Abstract: An appliance such as a refrigerator receives a demand response signal indicating a peak demand period and operates the refrigerator in an energy savings mode by disabling an anti-sweat heater. A sensor on an external surface of the refrigerator enables the anti-sweat heater during the peak demand period if moisture is detected by the sensor. A preselected location can be defined where incipient moisture would form such as reducing the amount of insulation in this location. By forming a depression in the location and using an impedance-type sensor, moisture can be easily detected. The sensor signal is sent to the controller which then activates the anti-sweat heater to remove the moisture.
