Patent number: 11969258Abstract: A surgical system includes at least one light emitter generating light at a first intensity and an array of light sensors including a least one row of light sensors, individual light sensors in the row of light sensors adapted to generate a signal including a non-pulsatile component. The system also includes a controller coupled to the array of light sensors, the controller including an analyzer to determine the magnitudes of the non-pulsatile components at the individual light sensors in the row of light sensors, to determine if the non-pulsatile component transitions from a higher magnitude to a lower magnitude and from a lower magnitude to a higher magnitude, and if so, to determine if the first intensity should be changed to a second intensity.Type: GrantFiled: July 17, 2020Date of Patent: April 30, 2024Assignee: Briteseed, LLCInventors: Amal Chaturvedi, Hariharan Subramanian, Jonathan Gunn, Mayank Vijayvergia, Shetha Shukair, Paul Le Rolland

Patent number: 9427161Abstract: An acoustic driver system includes an active acoustic driver and a passive acoustic driver. The active acoustic driver is configured to produce oscillating acoustic energy. The passive acoustic driver is acoustically connected to the active acoustic driver and is configured to receive the oscillating acoustic energy and to convert it into shear waves. The passive acoustic driver includes a housing member and a vibrating member. The housing member includes a housing member cavity. The vibrating member is disposed at least partially within the housing member cavity. The vibrating member permanently retains a curved shape while disposed within the housing member cavity.Type: GrantFiled: July 23, 2013Date of Patent: August 30, 2016Assignee: Northwestern UniversityInventors: Mayank Vijayvergia, Gaurav Gadodia, Sumeeth Jonathan, Samantha By, Frank Miller, Timothy Carroll, Teresa Woodruff
