Patent number: 10393704Abstract: A sensing system utilizes a channel, a BAW resonator structure including piezoelectric material with a c-axis having an inclined orientation, at least one functionalization material arranged over an active region of the BAW resonator structure, and a driving circuit configured to apply AC signals at different frequencies to cause the piezoelectric material to selectively exhibit a dominant shear response or a dominant longitudinal response. Driving the piezoelectric material in longitudinal mode induces localized fluid mixing proximate to the active region, whereas driving in shear mode permits detection of analyte bound to the at least one functionalization material in a liquid environment. Recesses may be defined in a surface of a top side electrode to enhance longitudinal mode mixing.Type: GrantFiled: October 31, 2016Date of Patent: August 27, 2019Assignee: QORVO US, INC.Inventors: Kevin McCarron, Rio Rivas

Patent number: 10393705Abstract: A method and system for determination of geometric features in an object is provided. The method includes receiving at least one geometric feature response to an ultrasound beam incident on the object. The incident ultrasound beam is produced from one of a plurality of ultrasound transducers. Further, a volumetric representation of the object is generated based on a plurality of object parameters. The volumetric representation of the object and a plurality of transducer parameters are used to generate a predicted beam traversal path in the object. The predicted beam traversal path is utilized to generate a temporal map of predicted time of flight geometric feature response to the ultrasound beam. A position on the volumetric representation of the object is determined as the location of the geometric feature, when the received geometric feature response is equivalent to the predicted time of flight geometric feature response corresponding to the position.Type: GrantFiled: July 18, 2013Date of Patent: August 27, 2019Assignee: General Electric CompanyInventors: Baskaran Ganesan, Satheesh Jeyaraman, Albrecht Maurer
