  • Patent number: 9863904
    Abstract: A method of analyzing a molecule is disclosed. A voltage source is selectively connected to or disconnected from a capacitor using a switch controlled by a reset signal. A charge is stored in a capacitor when the voltage source is connected to the capacitor. The capacitor is discharged through a nanopore in a membrane when the voltage source is disconnected from the capacitor. A duty cycle of the reset signal is determined such that the voltage source and the capacitor is connected for at least a one tenth portion of a reset signal period and disconnected for a remaining portion of the reset signal period, such that a voltage across the nanopore is maintained at a higher level during the portion of the reset signal period in which the connection is maintained than during the remaining portion of the reset signal period in which the connection is not maintained.

  • Patent number: 9857294
    Abstract: Described herein is an approach using inexpensive, disposable chemical sensor probes that can be mounted on a small unmanned aerial vehicles (UAVs) and used to analyze a site (such as one known or suspected to contain explosive residue, spilled material or contaminated soil) without the need for a person to conduct ground operations at the site. The method involves contacting a soil or a surface with a filter paper wetted with a solvent, then subjecting the filter paper to spectroscopy, thus detecting a possible variation indicative of one or more analytes, wherein the solvent is a deep eutectic solvents consisting of a mixture of ethylene glycol and choline chloride.

  • Patent number: 9847750
    Abstract: A solar energy collection system for converting solar energy to electricity that includes solar arrays mounted on a frame. Each array is set on a tracker head that is supported on a pedestal; each pedestal mounts onto a beam. Elevators pivot the arrays, where each elevator is made up of a shaft with a threaded end coupled to a drive nut. An upper end of each drive nut gimbal mounts to a portion of the tracker head; rotating a lower end of each shaft raises or lowers the drive nut, thereby pivoting each array. The vertical shafts are ganged together and driven by a single motor. Further included with each pedestal are azimuth orientation shafts that also mount to each tracker head. Rotating each orientation shaft adjusts an azimuth of an associated array. The orientation shafts are ganged together and are rotated by a single motor.

  • Patent number: 9786803
    Abstract: The invention relates to a multi-layer weatherable film structure having an outer layer of a highly weatherable film, a layer having a high thermal deformation temperature, an optional tie layer, and a thin layer of polyolefin or polyamide. The highly weatherable film layer preferably is polyvinylidene fluoride. The polyolefin or polyamide layer is less than 500 microns in thickness, and preferably the whole film structure is less than 750 microns thick. The polyolefinjpolyamide side of the film structure can easily be adhered to many different substances—especially polyolefins and polyamides. This film can be used to provide a highly weatherable protective layer a substrate. One useful application for the film is in a photovoltaic module to protect the back side of the module from weathering and abrasion. The multi-layer film structure can be adhered to a typical polyolefin-based encapsulant layer and used as a backsheet encapsulant in a photovoltaic module.
