Patent number: 11379708Abstract: An integrated circuit such as, for example a graphics processing unit (GPU), includes a dynamic power controller for adjusting operating voltage and/or frequency. The controller may receive current power used by the integrated circuit and a predicted power determined based on instructions pending in a plurality of processors. The controller determines adjustments that need to be made to the operating voltage and/or frequency to minimize the difference between the current power and the predicted power. An in-system reinforced learning mechanism is included to self-tune parameters of the controller.Type: GrantFiled: July 17, 2019Date of Patent: July 5, 2022Assignee: NVIDIA CorporationInventors: Sachin Idgunji, Ming Y. Siu, Alex Gu, James Reilley, Manan Patel, Rajeshwaran Selvanesan, Ewa Kubalska

Publication number: 20210131684Abstract: A system that provides effective and efficient introduction of water droplets into an air flow. The water droplets are sufficiently small so as to evaporate primarily before leaving the mixing enclosure where the droplets are injected by spray nozzles. Large droplets are kept to a minimum, thus reducing condensation and water accumulation to a very small amount. An amount of water usage is significantly less than that of a conventional evaporative humidifier of the same capacity. The present system may be placed in an enclosure that can readily replace other conventional evaporative humidifiers in enclosures. The present enclosure and system may be installed in lieu of a conventional enclosure and evaporative humidifier with minimal effort. The present enclosure has features that facilitate droplet to air mixing, viewing, humidification, and testing. In permissible situations, the present system may replace a conventional system but retain the conventional enclosure.Type: ApplicationFiled: January 12, 2021Publication date: May 6, 2021Inventors: Andrzej Peczalski, Grant Wood, Jason L. Ableitner, Lauren Seymour, Brad A. Terlson, Thomas M. Rezachek, Alex Gu, Charles N. Hoff, Andrew Smith, Chris Ohlsen, Adam D. McBrady

Patent number: 8790445Abstract: Air scrubbers and approaches for removing CO2, SO2, and other gaseous contaminates from gas emissions. An approach for removing a gaseous contaminant from a gas emission may include providing a supply of an ionic liquid. The gaseous contaminant may be absorbable in the ionic liquid. The approach may also include spraying the ionic liquid into the gas emission. The gaseous contaminant in the gas emission may be absorbed in the ionic liquid. The ionic liquid having the gaseous contaminant absorbed therein may be collected on a counter electrode and separated from the gas emission. Spraying the ionic liquid into a gas emission may include ultrasound agitation of the ionic liquid. The approach may also include venting the gas emission having the gaseous contaminant separated therefrom.Type: GrantFiled: May 24, 2010Date of Patent: July 29, 2014Assignee: Honeywell International Inc.Inventors: Alex Gu, Wei Yang, Tariq Samad

Patent number: 8376031Abstract: A blowerless heat exchanger apparatus based on micro-jet entrainment is disclosed. The heat exchanger apparatus incorporates a number of fins regularly spaced apart from each other and parallel to each other, thus letting air currents flow in the space defined between them. A dense array of micro-jet nozzles can be fabricated on the fins surface pointing to the flow direction of the air movement in order to induce increase airflow. The air from an air compressor delivers sufficient airflow on the fins surface utilizing micro-jets entrainment. The micro-jet entrainment confirms strong turbulent around the micro-jets and suggests significant heat transfer enhancement. The turbulence from the micro-jets enhance the heat transfer coefficient, potentially by an order of magnitude, therefore allowing much larger fin spacing and leads to huge reduction of flow resistance and overall power consumption.Type: GrantFiled: July 29, 2008Date of Patent: February 19, 2013Assignee: Honeywell International Inc.Inventors: Wei Yang, Chunbo Zhang, Steven J Eickhoff, Alex Gu

Patent number: 8335083Abstract: An apparatus includes a plurality of islands each carrying multiple cantilevers. The apparatus also includes a fluidic network having a plurality of channels separating the islands. The channels are configured to provide fluid to the islands, and the fluid at least partially fills spaces between the cantilevers and the islands. Heat from the islands vaporizes the fluid filling the spaces between the cantilevers and the islands to transfer the heat away from the islands while driving the cantilevers into oscillation. The apparatus may also include a casing configured to surround the islands and the fluidic network to create a vapor chamber, where the vapor chamber is configured to retain the vaporized fluid. The islands and the fluidic network could be formed in a single substrate, or the islands could be separate and attached together by a binder located within the channels of the fluidic network.Type: GrantFiled: October 21, 2010Date of Patent: December 18, 2012Assignee: Honeywell International Inc.Inventors: Wei Yang, Steven J.

The selected chemicals in the air sample are captured by ionic fluid electrospray plume and accumulate on the counter electrode.Type: GrantFiled: March 19, 2009Date of Patent: August 14, 2012Assignee: Honeywell International Inc.Inventors: Alex Gu, Adam Dewey McBrady, Wei Yang

Patent number: 8241919Abstract: A method includes acquiring a chemical sample and modulating the chemical sample at a frequency greater than a drift frequency of a sensor. The method also includes determining at least one of a presence and a concentration of the analyte within the modulated chemical sample using the sensor. Modulating the chemical sample could include alternately absorbing at least some of the analyte into a sorbent material and releasing at least some of the analyte from the sorbent material. Modulating the chemical sample could also include heating the sorbent material, absorbing part of the analyte into the sorbent material, and passing a remaining portion of the analyte into the sensor. Modulating the chemical sample could further include stopping the heating of the sorbent material, releasing the part of the analyte from the sorbent material, and passing the sample with the released part of the analyte into the sensor.Type: GrantFiled: October 28, 2008Date of Patent: August 14, 2012Assignee: Honeywell International Inc.Inventors: Adam Dewey McBrady, J.
