Publication number: 20220381890Abstract: Front-end circuitry for an ultrasound system comprises a beamformer FPGA integrated circuit, transmit ICs with both pulse transmitters and linear waveform transmitters and T/R switches, transmit control and receiver ICs, and analog-to-digital converter (ADC) ICs. Only the transmit ICs require high voltages, and the transmit/receive switches are integrated in the transmit ICs, isolating the receiver ICs from high voltages. The transmitters can be trimmed to adjust the pulse rise and fall rates, enabling the transmission of pulses with low harmonic frequency content and thus better harmonic images.Type: ApplicationFiled: August 9, 2022Publication date: December 1, 2022Inventors: Steven Russell Freeman, Scott Owen Schweizer, Timothy Savord, Jason Thanh Nguyen, Manfred Uwe Bartz, Truong Nguyen

Patent number: 11480674Abstract: A digital transmit beamformer for an ultrasound system has a waveform sample memory which stores sequences of samples of different pulse transmit waveforms of differing pulse widths. The memory is shared by a plurality of transmit channels, each of which can access its own selected sample sequence, independent of the selections by other channels. Waveform sample readout by the channels occurs substantially simultaneously during a transmit event, producing a transmit beam from a transmit aperture with different pulse waveforms applied to different elements of the transmit aperture. Higher energy waveforms with wider pulse widths are applied to central elements of the aperture and lower energy waveforms with narrower pulse widths are applied to lateral elements of the aperture to produce an apodized transmit beam.Type: GrantFiled: July 19, 2019Date of Patent: October 25, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Changhong Hu, Steven Russell Freeman

Patent number: 11471831Abstract: A method for regenerating a deNOx catalyst includes contacting the catalyst with steam at a temperature in the range of from 250 to 390° C. The method also includes reducing the amount of nitrogen oxide components in a process gas stream that includes a) contacting the process gas with a deNOx catalyst which results in the conversion of nitrogen oxide components as well as a decline in the NOx conversion over the deNOx catalyst; and b) regenerating the deNOx catalyst to improve the NOx conversion by contacting the deNOx catalyst with steam at a temperature in the range of from 250 to 390° C.Type: GrantFiled: September 25, 2017Date of Patent: October 18, 2022Assignee: SHELL USA, INC.Inventors: Wenzhong Zhang, Geert Marten Bakker, Steven Russell Lee

Publication number: 20220313217Abstract: The present disclosure describes ultrasound systems and methods configured to interrogate the stiffness and/or elasticity of a target tissue via shear wave imaging Systems may be configured to stroboscopically transmit a plurality of push pulses into the target tissue at different focal depths. The quickly transmitted push pulses may generate shear waves that constructively interfere to form a composite shear wave. Example systems may include a beamformer configured to transmit push pulse parameters to a transducer array while receiving new push pulse parameters from a controller. Dual transmission and receipt of different push pulse parameters reconfigures the beamformer without interrupting push pulse transmission, thereby minimizing the delay between successive push pulses. Push pulses transmitted according to the disclosed methods may generate a composite shear wave configured to interrogate tissue with enhanced sensitivity across a broad depth.Type: ApplicationFiled: May 14, 2020Publication date: October 6, 2022Inventor: Steven Russell Freeman

Patent number: 11364014Abstract: Front-end circuitry for an ultrasound system is described which comprises a beamformer FPGA integrated circuit, transmit ICs with both pulse transmitters and linear waveform transmitters, transmit control and receiver ICs, and analog-to-digital converter (ADC) ICs. Waveform data for both the linear and pulser transmitters is stored in the transmit control and receiver ICs, saving pins on the FPGA, which is the conventional source of this data. The ADCs couple digital echo data to the FPGA for beamforming over serial bus lines, saving additional FPGA pins over a conventional parallel data arrangement. The inclusion of both pulser and linear waveform transmit capabilities in the transmit ICs enables the use of both types of transmitters in the formation of a multi-mode image, such as use of the pulsers for Doppler beams and linear transmitters for B mode beams in the formation of a colorflow image.Type: GrantFiled: July 26, 2017Date of Patent: June 21, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Steven Russell Freeman, Truong Huy Nguyen, Manfred Bartz, Jason Thanh Nguyen, Timothy Savord, Scott Owen Schweizer

Publication number: 20220137211Abstract: Systems and methods for processing an analog waveform before it is sampled by an analog-to-digital converter (ADC) for the purpose of multiline beamforming in an ultrasound system are provided. The multiline beamforming is enabled by delaying the same waveform by two different time delays and by re-combining the delayed waveforms. This approach leverages an architecture that can also be used for temporal filtering, in which a single acoustic signal can be read out of the ARAM twice, separated by time, taking advantage of the fact that the ARAM allows for non-destructive read operations.Type: ApplicationFiled: January 20, 2022Publication date: May 5, 2022Inventor: Steven Russell Freeman

Publication number: 20220128445Abstract: A method and apparatus to create water vapor supersaturation and particulate counts from an air sample. The method and apparatus include introducing an air sample into a chamber connected to an optical detector and an outlet by pumping at the outlet. The method further includes passing air through the chamber and optical detector in a steady flow, and subsequently closing the inlet while continuing the pumping to expand the air sample and exhaust a portion of the air sample through the optical detector. The walls of the particle chamber are wetted with a fluid such as water, and one portion of the wall is warmer than the other portions such that there is some condensational growth prior to the expansion, and yet more condensational growth during the expansion. The cycles are repeated by continuously repeating the introducing, passing and closing.Type: ApplicationFiled: January 5, 2022Publication date: April 28, 2022Applicant: Aerosol Dynamics Inc.Inventors: Susanne Vera Hering, Gregory Stephen Lewis, Steven Russel Spielman

Patent number: 11249188Abstract: Systems and methods for filtering an analog waveform before it is sampled by an analog-to-digital converter (ADC) in an ultrasound system are provided. The waveform can be filtered by delaying the same waveform by two different time delays and combining the delayed waveforms to effectively cancel out the fundamental components, thereby providing more sensitive detection of harmonic components in received echo signals. This filtering approach leverages an architecture that can also be used for multiline beamforming to perform the temporal filtering, in which a single acoustic signal can be read out of the ARAM twice, separated by time, taking advantage of the fact that the ARAM allows for non-destructive read operations.Type: GrantFiled: December 28, 2016Date of Patent: February 15, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventor: Steven Russell Freeman

Publication number: 20220026332Abstract: A method and apparatus to create water vapor supersaturation and particulate counts from an air sample. The method and apparatus include introducing an air sample into a chamber by passing a flow into the chamber through the inlet by pumping at the outlet. The method further includes closing the inlet while continuing the pumping to exhaust the air sample from the chamber through the outlet. The pumping is performed at a rate operable to reduce pressure inside the chamber such that the air sample in the central portion of the chamber cools, and water vapor from walls of the chamber has time to diffuse into the air sample in the chamber from the walls. The cycles are repeated by continuously repeating the introducing and closing. The walls of the chamber may be wet or dry.Type: ApplicationFiled: October 4, 2021Publication date: January 27, 2022Applicant: Aerosol Dynamics Inc.Inventors: Susanne Vera Hering, Gregory Stephen Lewis, Steven Russel Spielman
