  • Patent number: 9983190
    Abstract: A device for passing a biopolymer molecule includes a nanochannel formed between a surface relief structure, a patterned layer forming sidewalls of the nanochannel and a sealing layer formed over the patterned layer to encapsulate the nanochannel. The surface relief structure includes a three-dimensionally rounded surface that reduces a channel dimension of the nanochannel at a portion of nanochannel and gradually increases the dimension along the nanochannel toward an opening position, which is configured to receive a biopolymer.

  • Publication number: 20180111599
    Abstract: A battery management system for an electrified powertrain of a hybrid vehicle includes one or more sensors configured to measure voltage, current, and temperature for a battery system of the hybrid vehicle and a controller. The controller is configured to obtain an equivalent circuit model for the battery system, determine a set of states for the battery system to be estimated, determine a set of parameters for the battery system to be estimated, receive, from the sensor(s), the measured voltage, current, and temperature for the battery system, using the equivalent circuit model and the measured voltage, current, and temperature of the battery system, estimate the sets of states and parameters for the battery system using a mixed sigma-point Kalman filtering (SPKF) and recursive least squares (RLS) technique, and using the sets of estimated states/parameters for the battery system, control an electric motor of the electrified vehicle.

  • Patent number: 9290806
    Abstract: A technique is provided for a structure. A substrate has a nanopillar vertically positioned on the substrate. A bottom layer is formed beneath the substrate. A top layer is formed on top of the substrate and on top of the nanopillar, and a cover layer covers the top layer and the nanopillar. A window is formed through the bottom layer and formed through the substrate, and the window ends at the top layer. A nanopore is formed through the top layer by removing the cover layer and the nanopillar.

  • Patent number: 9222930
    Abstract: A mechanism is provided for forming a nanodevice. A reservoir is filled with a conductive fluid, and a membrane is formed to separate the reservoir in the nanodevice. The membrane includes an electrode layer having a tunneling junction formed therein. The membrane is formed to have a nanopore formed through one or more other layers of the membrane such that the nanopore is aligned with the tunneling junction of the electrode layer. The tunneling junction of the electrode layer is narrowed to a narrowed size by electroplating or electroless deposition. When a voltage is applied to the electrode layer, a tunneling current is generated by a base in the tunneling junction to be measured as a current signature for distinguishing the base. When an organic coating is formed on an inside surface of the tunneling junction, transient bonds are formed between the electrode layer and the base.

  • Publication number: 20150284791
    Abstract: A mechanism is provided for reducing entropy of a polyelectrolyte before the polyelectrolyte moves through a nanopore. A free-standing membrane has the nanopore formed through the membrane. An agarose gel is formed onto either and/or both sides of the nanopore in the membrane. The agarose gel is a porous material. The polyelectrolyte is uncoiled by driving the polyelectrolyte through the porous material of the agarose gel via an electric field. Driving the polyelectrolyte, having been uncoiled and linearized by the agarose gel, into the nanopore is for sequencing.
