Patent number: 11773437Abstract: A circuit comprising a substrate with sectors on the substrate is provided, each sector comprising clock and data lines, a controller in electrical communication with the clock and data lines, a counter bias line, an amplifier input line and nano-electronic measurement devices on the substrate. A source of each device is coupled to the counter bias line and a drain of each device is coupled to the amplifier input line to obtain an electrical signal on the drain, the identity of which is determined by electrical interaction between the device and a charge label. Each device drain is gated by a corresponding switch between an on state, in which the drain is connected to the amplifier input line, and an off state, in which the drain is isolated from the amplifier input line. The controller controls switch states responsive to clock signal line pulses and data input line data.Type: GrantFiled: December 17, 2018Date of Patent: October 3, 2023Assignee: Pacific Biosciences of California, Inc.Inventors: Stephen Turner, Jonas Korlach, Steven Warren

Patent number: 10921314Abstract: Methods of making an integrated circuit for a single-molecule nucleic-acid assay platform. In one example, the method includes adhering a carbon nanotube to a surface of a transfer film, the transfer film comprising gold or a polymer; placing the surface of the transfer film on a CMOS integrated circuit; releasing the carbon nanotube from the transfer film; and forming a pair of post-processed electrodes proximate opposing ends of the carbon nanotube, the post-processed electrodes electrically connecting the carbon nanotube to the CMOS integrated circuit. The method can also include exposing the carbon nanotube to a diazonium salt solution to form a point defect on a portion of the carbon nanotube.Type: GrantFiled: May 31, 2019Date of Patent: February 16, 2021Assignee: THE TRUSTEES OF COLUMBIA UNIVERSITY IN THE CITY OF NEW YORKInventors: Kenneth L.

Patent number: 5681160Abstract: A flare tip structure has a tubular component usually mounted at the top of a flare sack which emits waste gas into the atmosphere for disposal by combustion with the aid of one or more pilot burners. Several fluid injectors are mounted inside the component and emit cones of injection fluid, such as natural around the axis of the tubular component. A deflector assists the injectors in creating a cushion of fluid just above the opening of the tubular component to space the combustion flame away from the opening. This allows surrounding air to flow into the gap between the opening and the combustion flame and to mix with waste gas prior to combustion to suppress smoke.Type: GrantFiled: July 19, 1995Date of Patent: October 28, 1997Inventors: John Ellis, John C. Boden, Dennis R. Adcock, Steven Warren
