Patent number: 10975746Abstract: A driver circuit drives a heater associated with a sensor in an exhaust system of a vehicle at a duty cycle. A feedback circuit generates a feedback signal indicating a temperature of the sensor. A ramp circuit outputs a first ramping set point indicating a first rate at which the temperature of the sensor is to be changed over a first time period after an engine of the vehicle is turned on, and a second ramping set point indicating a second rate at which the temperature of the sensor is to be changed after the first time period until the temperature of the sensor reaches a predetermined temperature. An error circuit generates first and second error signals based on the feedback signal and the first and second ramping set points. A controller controls the duty cycle of the driver circuit to drive the heater based on one or more gains.Type: GrantFiled: December 12, 2019Date of Patent: April 13, 2021Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Scott R.

Publication number: 20200149484Abstract: Methods and systems for predicting a vehicle stop event and/or operating a purge pump for a vehicle are disclosed. An example method includes providing a fuel vapor canister in fluid communication with a fuel tank of the vehicle, the fuel vapor canister configured to absorb fuel vapors from the fuel tank, and placing a purge pump in fluid communication with the fuel vapor canister, with the purge pump being configured to pump an external airflow into the canister. Some methods and systems may be directed to predicting a vehicle stop while the vehicle is moving based upon at least a model of vehicle speed, and initiating a vehicle response based upon the prediction. In some examples, a vehicle response includes reducing ambient noise emitted by the purge pump.Type: ApplicationFiled: November 9, 2018Publication date: May 14, 2020Inventors: Jianyang Geng, Weiyu Wang, Scott R.

Patent number: 7183073Abstract: A device and method are provided for isolating and culturing microorganisms from a bulk fluid sample. The device comprises a container having therein a polymeric immobilization layer having interstitial spaces between polymer chains such as a gel matrix. The interstitial spaces are of an average size less than an average size of microorganisms to be separated from the sample and cultured. A bulk fluid sample is applied to the immobilization layer where fluid is absorbed by the layer and microorganisms remain on the surface of the layer. After culturing, microorganism colonies are readily accessible on the surface of the layer for harvest and testing. The immobilization layer may contain one or more of nutrients for microorganisms growth, lytic agents, lytic enzymes, antibiotics, antibiotic neutralizers, indicators, detergents and selective agents. An adjacent support layer may be above and/or below the immobilization layer.Type: GrantFiled: May 2, 2003Date of Patent: February 27, 2007Assignee: bioMerieux, Inc.Inventors: Jones M. Hyman, Paul M.

Publication number: 20020083090Abstract: A method for storing, organizing and providing remote electronic access to documents. A cover sheet including a standard set of identification data characterizing each document is developed and stored. A digital version of each document is created and stored by scanning each contract. Each digital version includes a scanned image and a searchable text file, wherein the text is overlaid with the image. An index of bookmarks identifying sections of the digital version of each document is generated. Selected fields of information are captured from the digital version of the document. The documents are organized and cross-referenced in a database that includes the captured information and additional information related to each document. Designated parties are alerted of critical dates associated with each document. Remote electronic access to the documents is provided over the internet.Type: ApplicationFiled: December 27, 2000Publication date: June 27, 2002Inventors: Scott R. Jeffrey, Gary L.

Patent number: 6251624Abstract: A method and apparatus for performing microbial antibiotic susceptibility testing include disposable, multi-chambered susceptibility plates and an automated plate handler and image acquisition and processing instrument is described. The susceptibility plates are inoculated with a suitable microorganism such as bacteria, fungi, protozoa, algae or viruses and anti-microbial agent(s) are applied that the microorganism is exposed to at a variety of concentrations or a gradient of each anti-microbial agent. The plates are then placed in the instrument, which monitors and measures the growth or lack thereof of the microorganisms. This data is used to determine the susceptibility of the microorganism to the antibiotics. Such a system automates anti-microbial susceptibility testing using solid media and Carbo-Bauer standardized result reporting. The system provides a level of automation previously associated only with broth micro dilution testing, while retaining the advantages of the manual disk diffusion test.Type: GrantFiled: February 11, 2000Date of Patent: June 26, 2001Assignee: Akzo Nobel N.V.Inventors: Paul M.
