Patent number: 12070312Abstract: The disclosed system determines a fetal blood oxygenation level. During operation, the system activates two or more light sources, having different wavelengths, which are positioned on the abdomen of a pregnant mammal to direct light into the maternal abdomen toward a fetus. Next, the system receives a set of mixed signals from a set of photodetectors, which are positioned at different locations on the maternal abdomen to receive reflected light that traverses both maternal and fetal tissue. The system then performs a filtering operation that removes signal components associated with a maternal heart rate and a maternal respiration rate from the set of mixed signals to produce a set of fetal signals. Next, the system combines the set of fetal signals to produce a composite fetal signal. Finally, the system determines the fetal blood oxygenation level by performing a pulse-oximetry computation based on the composite fetal signal.Type: GrantFiled: March 16, 2020Date of Patent: August 27, 2024Assignee: The Regents of the University of CaliforniaInventors: Soheil Ghiasi, Daniel Fong

Patent number: 11904172Abstract: An external device transfers a key to an implantable medical device over a proximity communication and then establishes a first far field communication session with the implantable medical device where the key is used for the first communication session. This first communication session may occur before implantation while the implantable medical device is positioned outside of the sterile field so that using a proximity communication is easily achieved. Once the implantable medical device is passed into the sterile field for implantation, the external device may then establish a second far field communication session with the implantable medical device where the last key that was used for the first communication session is again used for the second communication session which avoids the need for another proximity communication to occur within the sterile field.Type: GrantFiled: August 31, 2020Date of Patent: February 20, 2024Assignee: MEDTRONIC, INC.Inventors: Warren W. Ball, Ajinkya M. Joglekar, Nathan A. Torgerson, Matthew L. Plante
