Unconstrained ear recognition using a combination of deep learning and handcrafted features.
Invented by a USF College of Engineering team led by Professor Sudeep Sarkar, the technology is an alternative to more common biometrics such as fingerprint, face and iris recognition technology. The ear is stable over time, less invasive to capture and does not require as much control during image acquisition as other biometrics, the inventors said. Dr. Sarkar was joined on the patent by USF PhD alum Earnest Eugene Hansley and Federal University of Bahia Professor Mauricio Pamplona Segundo of Brazil.
Devices and methods for measuring blood coagulation.
People who suffer from hemophilia and other bleeding disorders, as well as the 2 million patients in the U.S. who take anticoagulant medicines, depend on technology that can measure the speed of blood coagulation to manage their conditions. USF College of Engineering Professor Anna Pyayt invented a three-dimensional, on chip photonic circuit that includes an optical waveguide that measures the refractive index of the blood. During coagulation, the refractive index of plasma increases and can be measured to study the complex coagulation process. The device can be easily packaged and integrated with mobile devices and laptops because no additional microfluidics are required.
Robotic end effectors for use with robotic manipulators.
Many existing grippers used in robotics today have limited capabilities in performing certain tasks or grabbing specific objects, or they have been designed to work with one kind of system. A USF mechanical engineering team that specializes in assistive technologies invented a gripper enabled with sensors and a camera for more precision, and with a cupped design that more closely mimics a human hand dexterity to allow for more accurate grasping. The gripper can be used with other computerized systems, including mobile devices. The inventors are Dr. Redwan Alqasemi, Research Professor of Mechanical Engineering, and lead researcher at USF’s Center for Assistive, Rehabilitation & Robotics Technologies; USF Department of Mechanical Engineering Chair Dr. Rajiv Dubey; engineering PhD student Lei Wu; and USF engineering alums Paul Mitzlaff, Andoni Aquirrezabal, and Karl Rothe.
Hormone treatment for age-related hearing loss - presbycusis.
Age-related hearing loss - presbycusis - is the most prevalent neurodegenerative disease and number one communication disorder of aging, and hearing loss affects hundreds of millions of people worldwide. USF researchers have developed a new drug combination involving FDA-approved compounds that achieves significant pre-clinical therapeutic effects in the treatment of age-related hearing loss. These compounds include aldosterone and an anti-inflammatory drug. The team is led by USF Department of Medical Engineering Chair Dr. Robert Frisina, who leads the Global Center for Hearing & Speech Research, and includes Professor Joseph Walton; Research Associate Professor Bo Ding and senior bioscientist Dr. Xiaoxia Zhu.
Ammonia removal in freshwater and saltwater systems.
When either fresh or saltwater fish are caught, they are often placed in a container to keep them alive to ensure freshness later. In such a confined space, ammonia buildup due to fish waste are two major concerns and high concentrations of ammonia can be lethal. A USF engineering research team has developed a new method to effectively control ammonia levels while preserving live fish or bait using a functionalized tectosilicate compound chabazite. This microporous mineral can absorb high amounts of ammonia while helping keep the fish alive. The inventors are USF Professors Dr. Norma Alcantar and Dr. Sarina Ergas, and Dr. Wen Zhao, who earned her PhD at the USF College of Engineering.
