Publication number: 20240129573Abstract: A processing system receives a user-generated media recording, and metadata associated with the user-generated feedback, from a first device. The user-generated media recording is a recording of the public end-user captured during a live media broadcast using a public-user interface on the first device. The metadata includes information linking the user-generated media recording to the live media broadcast. The system stores the user-generated media recording and the first metadata in one or more storage devices, and transmits a version of the user-generated media recording and at least a portion of the first metadata to a private-user interface on a second device. The private-user interface is configured to receive input from a private end-user selecting the version of the user-generated media recording for broadcast during the same live media broadcast during which the user-generated media recording was created.Type: ApplicationFiled: October 12, 2022Publication date: April 18, 2024Applicant: iHeartMedia Management Services, Inc.Inventors: Albert Curtis Mitchell, Michael Scott Woodruff, Adam Michael Roberts, Steven Douglas Wight, Siu Leung Chan, Jacob Earl Bolton, Stephen William Bain, Qian Chang, Davis Scott Harlan

Publication number: 20220380403Abstract: Photon generating substrates for light-directed oligonucleotide synthesis are disclosed. Light is generated within a solid-state stack that supports growing oligonucleotides. The light may be generated by microLEDs, a pass-through liquid crystal panel, or an LCoS system. Light passes through a transmissive layer on which growing oligonucleotides are attached. Patterning of the light is controlled by selective activation of the microLEDs or by selective control of the transparency of a liquid crystal layer. Photolabile blocking groups are selectively removed by exposure to patterned light emitted from the photon generating substrate.Type: ApplicationFiled: May 26, 2021Publication date: December 1, 2022Inventors: Bichlien Hoang Nguyen, Karin Strauss, Jake Allen Smith, Richard Prescott Rouse, Douglas Mitchell Carmean, Matthew David Turner, Gagan Gupta

Patent number: 11286826Abstract: Various embodiments relate to a selective catalytic reduction system for treating exhaust gases of an internal combustion engine. The system includes an inlet section that receives exhaust gases from the engine. The system includes a tank storing diesel exhaust fluid (“DEF”), a pump, a valve, and an injector each in fluid communication with each other. The injector is coupled to the inlet exhaust pipe and configured to inject DEF into the exhaust gases flowing through the inlet exhaust pipe in a plurality of pulses. Each of the plurality of pulses injects a constant volume of DEF into the inlet exhaust pipe. The system further includes a controller configured to operate the pump and the valve such that a time interval between successive constant volume pulses of the plurality of pulses is varied based on a variable oxides of nitrogen content of the exhaust gases.Type: GrantFiled: September 16, 2019Date of Patent: March 29, 2022Assignee: Cummins Emission Solutions, Inc.Inventors: Douglas Mitchell, A.

Patent number: 10325061Abstract: Various aspects of the disclosed technology relate to axial thrust analysis of turbomachinery designs. A cavity of a turbomachinery design is divided into sub-cavities. Magnitudes of horizontal components of forces exerted on rotational faces in each of the sub-cavities are computed based on computational fluid dynamics, areas of the rotational faces and angles of the rotational faces. The horizontal components are components along a rotational axis of the turbomachinery design. Directions of the horizontal components of the forces are determined based on how many faces a line parallel to the rotational axis intersects between a rotational face of interest and a side of the cavity. A thrust force on a turbine of the turbomachinery design attributed to secondary fluid systems is computed using the magnitudes and the directions of the horizontal components of the forces.Type: GrantFiled: March 9, 2017Date of Patent: June 18, 2019Assignee: Mentor Graphics CorporationInventors: Michael James Croegaert, Douglas Mitchell Kolak, Jacob Arlington Nuetzel
