Patent number: 10577617Abstract: The impact of plastid size change in both monocot and dicot plants has been examined. In both, when plastid size is increased there is an increase in biomass relative to the parental lines. Thus, provided herein are methods for increasing the biomass of a plant, comprising decreasing the expression of at least one plastid division protein in a plant. Optionally, the level of chlorophyll in the plant is also reduced.Type: GrantFiled: January 13, 2016Date of Patent: March 3, 2020Assignees: The Board of Trustees of the University of Illinois, The United States of America, as Represented by the Secretary of Agriculture, The Board of Regents of the University of Nebraska, The University of Florida Research Foundation, IncorporatedInventors: Aleel K.

Publication number: 20170022512Abstract: Disclosed herein are transgenic plants and plant cells having increased photosynthetic rate, increased biomass production, and/or improved cold tolerance compared to control plants (such as non-transgenic plants of the same species as the transgenic plants). In some examples, the transgenic plants/plant cells contain a plant transformation vector including a nucleic acid encoding a pyruvate orthophosphate dikinase (PPDK) polypeptide. Also disclosed herein are methods for making the transgenic plants, for instance by introducing into progenitor cells of the plant a plant transformation vector including a nucleic acid that encodes a PPDK polypeptide, and growing the transformed progenitor cells to produce a transgenic plant, in which the PPDK nucleic acid is expressed. Further disclosed herein are PPDK-encoding nucleic acids, PPDK polypeptides, and plant transformation vectors of use in producing the transgenic plants or plant cells.Type: ApplicationFiled: July 22, 2016Publication date: January 26, 2017Inventors: Stephen P.

Patent number: 7421773Abstract: Silicon-based high pressure sensor modules are manufactured in an array arrangement, incorporating a low temperature cofired ceramic (LTCC) substrate. The LTCC substrate can withstand high pressures. Bossed containers filled with oil are mounted on the substrate in an array. These bossed containers house the sensor cells which are composed of a sensor handle wafer and a diaphragm. The top surface of these bossed containers are flexible and deflect under pressure. By controlling the surface area and the thickness of the top surface, the pressure sensors can be configured to measure a wide range of pressures. The oil transfers pressure from the bossed container to the diaphragm of the sensor cell while protecting the sensor cell from high pressures and harsh media.Type: GrantFiled: April 27, 2007Date of Patent: September 9, 2008Assignee: Delphi Technologies, Inc.Inventors: Timothy A. Vas, Timothy M. Betzner, Stephen P. Long

Patent number: 7117747Abstract: A technique for manufacturing an integrated pressure sensor includes a number of steps. Initially, a substrate with conductive electrical traces located on first and second sides of the substrate is provided. A plurality of compensation circuits are positioned in an array on the first side of the substrate in electrical contact with one or more of the conductive electrical traces on the first side of the substrate. A plurality of pressure sensors are positioned on the second side of the substrate in electrical contact with one or more of the conductive electrical traces on the second side of the substrate.
