Patent number: 10751663Abstract: A system for providing ultraviolet treatment of volatile organic compounds (VOCs) is disclosed. The system can include a first gas conduit to carry a stream of gas having VOCs and a second gas conduit to carry a second stream of gas containing a partial pressure of water vapor. A gas treatment unit can be coupled to the first gas conduit and the second gas conduit. The gas treatment unit can form hydroxyl radicals from the water vapor in the stream of gas carried by the second gas conduit and inject the radicals in the first gas conduit to decrease the presence of the VOCs. The gas treatment unit can include a photocatalyst component and at least one ultraviolet radiation source to irradiate the photocatalyst component with ultraviolet radiation. To this extent, the irradiated photocatalyst component disassociates the gas containing the water vapor to form the hydroxyl radicals.Type: GrantFiled: June 5, 2018Date of Patent: August 25, 2020Assignee: Sensor Electronic Technology, Inc.Inventor: Maxim S.

Patent number: 10729332Abstract: An apparatus, system, and method monitors the motion, breathing, heart rate and sleep state of subjects, e.g., humans, in a convenient, non-invasive/non-contact, and low-cost fashion. More particularly, the motion, breathing, and heart rate signals are obtained through processing applied to a raw signal obtained in a non-contact fashion, typically using a radio-frequency sensor. Periods of sleep disturbed respiration, or central apnea can be detected through analysis of the respiratory signal. The mean heart rate, and derived information, such as the presence of cardiac arrhythmias can be determined from the cardiac signal. Motion estimates can be used to recognize disturbed sleep and periodic limb movements. The sleep state may be determined by applying a classifier model to the resulting streams of respiratory, cardiac and motion data.
