Abstract: A control system and method for sectionalizing switches and a source interrupter/recloser in a feeder, or portion of the distribution grid, which enables fault location, isolation and service restoration without requiring a communications infrastructure and communications equipment at the switches. The method includes each switch adaptively configuring fault-count, load-count and voltage-count thresholds upon which the switch should open. The thresholds for each switch are based on the switch's proximity to the active feeder source, which requires a determination of which source is powering the feeder at a particular time. Five different methods are disclosed to determine which source is active. When a fault is detected, the source interrupter/recloser opens and then begins a pulse testing or reclosing sequence, where the switches open to isolate the fault when reaching their fault-count or voltage-count threshold.

Abstract: A control system and method for sectionalizing switches and pulse-testing interrupter/reclosers in a distribution grid feeder which enables fault location, isolation and service restoration without requiring an external communications infrastructure to pass information between the switches. The method includes switches entering an armed state when they experience a high fault current during an initial fault event. Then, when the interrupter/recloser runs its test pulse sequence, any armed switch counts all test pulses as fault pulses, while non-armed switches count the test pulses as load pulses. Switches open to isolate the fault based on threshold values of fault pulse count and load pulse count. When an initially active interrupter/recloser completes its test pulse sequence, another interrupter/recloser begins its sequence, and all switches reconfigure their threshold values based on the new interrupter/recloser.

Abstract: A power restoration system comprising a feeder, a plurality of power sources available to provide power to the feeder, a plurality of normally closed reclosing devices electrically coupled along the feeder, at least one normally open recloser electrically coupled to the feeder, and a plurality of normally closed switches electrically coupled along the feeder between each adjacent pairs of normally closed reclosing devices. Each switch is assigned a position code having a value for each of the plurality of power sources that determines when the switch will open in response to the fault current and which power source the switch is currently receiving power from, where timing control between the reclosing devices and the switches allows the switch to be selectively opened to isolate the fault within a single feeder section between each pair of adjacent switches or between each switch and a reclosing device.

Abstract: Methods, systems, and devices for leakage current reduction in electronic devices are described. Electronic devices may be susceptible to leakage currents when operating in a first mode, such as an inactive (e.g., a standby) mode. To mitigate leakage current, an electronic device may include transistors coupled in cascode configuration where a gate of a drain-side transistor in the cascode configuration is configured to be biased by an adjustable (e.g., a dynamic) control signal. When the transistors are inactive (e.g., “off”), the control signal may be adjusted to prevent leakage associated with the inactive transistors. Further, a source-side transistor in the cascode configuration may be configured to have a high threshold voltage (e.g., relative to the drain-side transistor).

Abstract: This invention discloses an approach regarding the use of solid-phase microextractions (SPMEs) in the analytical, bioanalytical, combinatorial sciences, and all other applicable areas of measurement science. The approach applies to the analysis of exceedingly small volumes of a liquid specimen (10s-100s of ?L), and how the concepts of negligible depletion (ND) can be used within the context of tradeoff between extractive (reaction) kinetics, extractive capacity, and sample flow rate as a means to obviate the need to deliver accurately a small volume sample for SPME analysis, improving the ease-of-use for a number of different SPME-based measurements including, for example, disease markers in immunoassays for health care.

Abstract: This invention discloses an approach is improve the strength and reproducibility of the signal generated in FTAs using solid-phase microextraction (SPME) through the design of an approach to generate the plasmonically-enhanced signal for SERS, surface-enhanced infrared (SEIRA), and other enhanced spectroscopies. The design incorporates: (1) a particle-particle coupling strategy that is triggered by the selective capture of an analyte to a particle that has been immobilized on a membrane and has been modified to act as a capture substrate; (2) the selective tagging of the captured analyte by a nanoparticle also designed to generate an amplified plasmonic signal upon tagging; and (3) the incorporation of an internal nanoparticle standard to account for fluctuations in flow rates and flow paths.

Abstract: This invention discloses a design of microplates and microarrays to improve utility. The new design constructs a physical flux barrier that limits thermocapillary and other mass transfer contributions to the heterogeneous accumulation of reactant at the surface of a well or array address. The improved control of reactant delivery results in a much more uniform distribution of reactant across an address, thereby improving the accuracy of the measured response.

Abstract: This invention discloses a pretreatment approach for blood and bodily fluids to remove unwanted protein interferences in the measurement of analytes. Enzymes either contained in a cartridge or immobilized on a solid support break down proteins that complex with the analyte to shield it from detection. This pretreatment significantly enhances the detectability of analytes and does not require subsequent clean-up steps that would normally be required to ensure the functionality of the analysis method, thereby, creating a simple yet powerful approach for sample pretreatment in a variety of settings ranging from a complex laboratory infrastructure to a field deployable application.
