Patent number: 11179050Abstract: Most automatic cuff blood pressure (BP) measurement devices are based on oscillometry. These devices estimate BP from the envelopes of the cuff pressure oscillations using fixed ratios. The values of the fixed ratios represent population averages, so the devices may be accurate only in subjects with normal BP levels. A patient-specific oscillometric BP measurement method was developed. The idea was to represent the cuff pressure oscillation envelopes with a physiologic model and then estimate the patient-specific parameters of the model, which includes BP levels, by optimally fitting it to the envelopes.Type: GrantFiled: September 9, 2016Date of Patent: November 23, 2021Assignees: Board of Trustees of Michigan State University, University of Maryland, College ParkInventors: Jiankun Liu, Mohsen Moslehpour, Jin-Oh Hahn, Ramakrishna Mukkamala

Patent number: 11179047Abstract: A system and method is presented for cuff-less blood pressure measurement in a mobile device. A key aspect of this disclosure is the discovery of a new location for blood pressure measurement at the fingertip of a subject and that reflectance-mode photoplethysmography can be used to help make this measurement. Through experiments in human subjects, it was discovered that it is indeed possible to measure systemic blood pressure by having a subject press the fingertip against a reflectance-mode photo-plethysmography-force sensor unit under visual guidance and then compute blood pressure from the resulting variable-amplitude blood volume oscillations and applied pressure via an oscillometric algorithm.Type: GrantFiled: July 18, 2019Date of Patent: November 23, 2021Assignee: Board of Trustees of Michigan State UniversityInventors: Ramakrishna Mukkamala, Anand Chandrasekhar, Jin-Oh Hahn

Publication number: 20210359408Abstract: A single-switch-per-bit topology for reconfigurable reflective surfaces (RRSs) is provided. Novel multi-bit unit-cell configurations are presented for radio-frequency (RF) RRSs with improved radiation efficiency and compact designs. Embodiments described herein realize a multi-bit RRS using an antenna array with multiple integrated switches at the ports of every antenna element (e.g., one at each port, providing one control bit per switch). By manipulating the states of the switches, the impinging waves on the surface are modulated, leading to beamforming in the desired direction. Some embodiments utilize a single switch-per-bit topology integrating single-pole-single-throw (SPST) switches (e.g., PIN diodes) into the unit-cell design, achieving up to 4 bits of phase quantization with only 4 switches. The exhibited radiation efficiency of the multi-bit RRS is significantly improved compared to lower bit configurations.Type: ApplicationFiled: May 18, 2021Publication date: November 18, 2021Applicant: Arizona Board of Regents on behalf of Arizona State UniversityInventors: Panagiotis Theofanopoulos, Georgios Trichopoulos
