Publication number: 20240005693Abstract: Aspects of this disclosure relate to a biometric sensing device that combines sensing with an actuator for two way communication between a finger on a surface and the device. The sensor can also function as an actuator. A finger can be authenticated based on an image of the finger generated by the sensor and also based on a response to energy delivered to the finger by the actuator. Two way communication can provide more robust authentication than fingerprint sensing alone.Type: ApplicationFiled: March 22, 2023Publication date: January 4, 2024Inventors: Butrus T. Khuri-Yakub, Morten Fischer Rasmussen, Gerard Touma, John N. Irwin, III

Publication number: 20220314034Abstract: Features for high intensity focused ultrasound (HIFU) are described. The application of HIFU for ablating tissue may be monitored in real time by imaging bubbles generated during HIFU. A single transducer array may be used by fast switching between imaging and HIFU. For imaging, the array or portions thereof may be used in receive only mode to locate bubbles generated by the HIFU. The application of HIFU, such as location and/or intensity, may be adjusted based on information from the imaging of the bubbles. Physicians and/or others may use these systems and methods to monitor HIFU procedures in real-time for optimal ablation of target tissue with minimal damage to healthy tissue.Type: ApplicationFiled: February 23, 2022Publication date: October 6, 2022Inventors: Ji Hoon Jang, George Quintin Stedman, Morten Fischer Rasmussen, Arif Sanli Ergun, Butrus T.
