Patent number: 11445996Abstract: A method of navigating and positioning an endovascular device in a vasculature is disclosed. Initially, a system including an endovascular device and at least one transducer is inserted into the lumen of a patient. An acoustic signal is then transmitted within the lumen. A reflected signal is pre-processed to extract one or more acoustic features. The one or more acoustic features are processed using a computer readable set of rules to produce an output related to guidance of the instrument within a blood vessel or a position of the instrument within the blood vessel.Type: GrantFiled: August 5, 2019Date of Patent: September 20, 2022Assignee: TELEFLEX LIFE SCIENCES LIMITEDInventors: Wenkang Qi, Bradley Hill

Patent number: 10922484Abstract: An audiobook quality control system may detect and flag errors in human voice recordings of manuscripts at real-time or near real-time. The system may receive a manuscript and process the manuscript to generate a comparison document. The system may receive audio data from a recording session and may use a speech-to-text transcription tool to generate transcribed audio. Based on comparing the transcribed audio to the comparison document, the system may flag differences as errors. Additionally, the system may flag common recording errors (e.g., consistency, pronunciation, spacing issue, noise, wrong words, etc.). Based on the error types and number of errors, the system may determine to re-record specific sections of the manuscript.Type: GrantFiled: June 28, 2018Date of Patent: February 16, 2021Assignee: Amazon Technologies, Inc.Inventors: Mark Pereira, Matthew Christilaw, Brian Pepera, Bradley Hill, Bridgette Oakes, Lawrence William McKay, III, Addam Kearney

Patent number: 9339207Abstract: A method for evaluating flow characteristics in a vessel of a patient includes the steps of positioning a catheter having a balloon at a measuring location within the vessel; transmitting an ultrasound signal into the vessel while the balloon catheter is within the measuring location; evaluating a reflection of the ultrasound signal to determine a flow parameter within the vessel while the catheter is in the measuring position; expanding the balloon within the vessel at the measuring location; and stopping the expanding step when the result of the evaluating step is that the flow through the vessel is substantially stopped. In some embodiments, the method may further comprise the step of detecting an endovascular electrogram signal. The method may be designed for evaluating flow characteristics in a vessel of a patient while enabling the prevention of a balloon from over-expanding and/or over-distending a vessel of a patient.Type: GrantFiled: January 23, 2009Date of Patent: May 17, 2016Assignee: VASONOVA, INC.Inventors: Sorin Grunwald, Bradley Hill, E.
