Patent number: 11664781Abstract: MEMS based sensors, particularly capacitive sensors, potentially can address critical considerations for users including accuracy, repeatability, long-term stability, ease of calibration, resistance to chemical and physical contaminants, size, packaging, and cost effectiveness. Accordingly, it would be beneficial to exploit MEMS processes that allow for manufacturability and integration of resonator elements into cavities within the MEMS sensor that are at low pressure allowing high quality factor resonators and absolute pressure sensors to be implemented. Embodiments of the invention provide capacitive sensors and MEMS elements that can be implemented directly above silicon CMOS electronics.Type: GrantFiled: September 14, 2020Date of Patent: May 30, 2023Assignee: Stathera IP Holdings Inc.Inventors: Vamsy Chodavarapu, George Xereas

Patent number: 10782235Abstract: Chemical sensors today are deployed in massive volumes across multiple industries and yet at the same time they are subject to substantial research and development effort to establish new, faster, lower cost, more accurate, more sensitive chemical sensors. Such sensors and sensor arrays are being exploited across chemistry, biology, clinical biology, environmental science in civilian and military markets. Amongst the many sensor methodologies are xerogel substrates with two moieties, a receptor for molecular recognition of the analyte and a luminophore for signaling the recognition event. In order to fulfill the requirements for low cost there is a requirement for electronic excitation/read circuits that can support architectures with optical source—N sensors—X filters—M detectors, where M?N and X=N|M.Type: GrantFiled: July 27, 2015Date of Patent: September 22, 2020Assignee: THE ROYAL INSTITUTION FOR THE ADVANCEMENT OF LEARNING / MCGILL UNIVERISTYInventors: Vamsy Chodavarapu, Daisy Daivasagaya, Adel Merdassi

Patent number: 10499822Abstract: Small implantable silicon-based devices offer an ability to revolutionize the management of trauma victims. For example, implantable pressure sensors allow the devastating outcomes of compartment syndrome to be minimized through continuous or periodic monitoring whilst being compatible with the ongoing drives to increase out-patient care and reduced hospitalization time. Further, small implantable silicon-based sensor microsystems according to embodiments of the invention whilst being capable of measuring pressures under diverse conditions are easily used by nurses in hospital settings as well as also being easily deployed by paramedical personnel in cases of accidents, natural disasters, war, etc. Beneficially, the implantable sensor microsystem will not interfere with movement of the patient during stabilization, surgery, intensive care stay, outpatient management, etc.Type: GrantFiled: May 8, 2015Date of Patent: December 10, 2019Assignee: The Royal Institution for the Advancement of Learning / McGill UniversityInventors: Edward Harvey, Vamsy Chodavarapu, Charles Allan

Patent number: 10488339Abstract: Apparatuses, methods, and computer program products for analyzing target compounds. An excitation signal comprising light having a time-varying intensity is transmitted into a target compound. In response to receiving the excitation signal, the target compound generates an emission signal. To increase the intensity of the emission signal, a fluorophore may be provided to the target compound. The fluorophore may be configured to react with a characteristic of the target compound so that the fluorophore generates the emission signal in response to the presence of both the characteristic and the excitation signal. The emission signal may be compared to the excitation signal in a frequency domain to determine a phase of the emission signal relative to the excitation signal. The phase may be used to determine a luminescence lifetime of the emission signal. If the detected luminescence lifetime matches an expected luminescence lifetime, the target compound likely includes the characteristic.Type: GrantFiled: March 5, 2019Date of Patent: November 26, 2019Assignee: University of DaytonInventor: Vamsy Chodavarapu
