Patent number: 11707595Abstract: This disclosure pertains to a system configured to control light exposure for circadian phase management and/or light deficient disorders of a subject. The system comprises a user interface, physiological sensors configured to generate output signals conveying physiological data of the subject, and a light control valve configured to block or reduce blue light ambient radiation reaching eyes of the subject. Processors are in communication with the user interface, the physiological sensors, the light control valve, and radiation generators. The processors cause the system to receive physiological goals of the subject, determine a light control plan based on the physiological goals, the physiological data, environmental data, and time data. The system operates the light control valve to block or reduce blue light ambient radiation based on the light control plan, and generate, using the one or more radiation generators, therapeutic light radiation based on the light control plan.Type: GrantFiled: September 24, 2019Date of Patent: July 25, 2023Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Michael Edward Colbaugh, Mark Anthony Bartolomeo, Stefanida Kononov Blake, Surya Subrahmanya Sreeram Vissapragada Venkata Satya, Andreas Ralph Maihoefer, Xia Chen, Boomika Kalyan

Patent number: 11266807Abstract: The present disclosure pertains to a system and method for determining whether a subject is likely to be disturbed by therapy levels of stimulation provided to the subject during sleep sessions. The present system is configured to automatically identify sensitive users using electroencephalogram (EEG) information from a reference sleep session with or without stimulation. For reference sleep sessions without stimulation, the alpha activity in detected deep sleep is used to predict whether the subject is likely to be disturbed by therapy levels of stimulation. For reference sleep sessions with stimulation, the acute increase in EEG delta (e.g., 0.5-4 Hz) power and/or an arousability index are used to predict whether the subject is likely to be disturbed by therapy levels of stimulation.Type: GrantFiled: December 27, 2017Date of Patent: March 8, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Gary Nelson Garcia Molina, Surya Subrahmanya Sreeram Vissapragada Venkata Satya, Stefan Pfundtner, Tsvetomira Kirova Tsoneva, Anandi Mahadevan

Patent number: 11253673Abstract: The system receives a raw signal carrying information related to slow wave activity; buffers a portion of the raw signal; determines a timing of slow wave events in the buffered portion of the raw signal; filters the raw signal; determines a timing of slow wave events in the filtered raw signal; compares the timing of the slow wave events in the buffered portion of the raw signal to the timing of the slow wave events in the filtered raw signal; determines a first correction factor associated with reducing slow wave activity in the subject and a second correction factor associated with enhancing slow wave activity in the subject; and adjusts a timing of the stimulation provided to the subject during the sleep session based on the first and/or second correction factors.Type: GrantFiled: December 7, 2017Date of Patent: February 22, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Gary Nelson Garcia Molina, Anandi Mahadevan, Surya Subrahmanya Sreeram Vissapragada Venkata Satya

Patent number: 11229397Abstract: The present disclosure pertains to a system configured to output an indicator representative of effects of stimulation provided to a subject during a sleep session. The indicator is determined based on a combination of the effect of stimulation on sleep restoration, stimulation quality, sleep architecture factors, and/or other information. The indicator is determined using age matched reference information on deep sleep duration and EEG slow wave activity. The contribution to the indicator associated with sleep architecture factors is determined based on age matched reference information including sleep onset latency, wake after sleep onset, total sleep time, micro-arousal count, sleep stage(s) prior to awakening, and/or other information.Type: GrantFiled: December 21, 2017Date of Patent: January 25, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Gary Nelson Garcia Molina, Tsvetomira Kirova Tsoneva, Stefan Pfundtner, Surya Subrahmanya Sreeram Vissapragada Venkata Satya, Anandi Mahadevan, Diane Kosobud

Patent number: 11179099Abstract: Systems and methods for classifying breathing disorders of subjects are based on the respiratory response to a change in a pressure level of a pressurized flow of breathable gas. The change presents a breathing challenge to a subject. The challenge may be limited to the inspiratory breathing phase. The inspiratory pressure level may be lower than the expiratory pressure level during challenges.Type: GrantFiled: February 4, 2019Date of Patent: November 23, 2021Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Michael Edward Colbaugh, Lauren Elizabeth Hueser, Surya Subrahmanya Sreeram Vissapragada Venkata Satya

Patent number: 11172865Abstract: The present disclosure pertains to a reference slow wave activity metric determination system. Instead of collecting information during sleep sessions without stimulation (e.g., baseline and/or sham sessions) to determine a reference amount of slow wave activity in a subject, the present system is configured to build a model between stimulation properties and slow wave enhancement, and determine the reference amount of slow wave activity in the subject (e.g., corresponding to what would occur during baseline sleep and/or sham sessions) using the model. Advantageously, this approach does not require performance of baseline and/or sham sleep sessions, and enables personalization of the reference amount of slow wave activity, which dynamically increases its accuracy as more information is collected.Type: GrantFiled: December 1, 2017Date of Patent: November 16, 2021Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Gary Nelson Garcia Molina, Anandi Mahadevan, Surya Subrahmanya Sreeram Vissapragada Venkata Satya, Annette Kapitan

Patent number: 11154256Abstract: Mouth-breathing can be detected in early phase expiration during respiratory treatments involving a pressure support device. In accordance with some embodiments, an output signal is received from a sensor that conveys information relating to one or more parameters of the pressurized flow of breathable gas as it is delivered to an air-way of a subject. Transitions are estimated between inspiratory phases and expiratory phases of respiration by the subject based on the one or more determined parameters. A local extreme is identified in a level of a first parameter during a given expiratory phase of respiration by the subject. The level of the first parameter is analyzed as a function of time within a sampling window to determine whether the subject is breathing by mouth during the given expiratory phase. The sampling window begins at or proximate to the identified local extreme in the level of the first parameter.Type: GrantFiled: October 11, 2012Date of Patent: October 26, 2021Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Surya Subrahmanya Sreeram Vissapragada Venkata Satya, Leonardo Alberto Baloa Welzien, Manuel Laura Lapoint

Patent number: 10549067Abstract: The present disclosure pertains to a system configured to a system configured to detect slow waves based on adjusted slow wave detection criteria and time delivery of the sensory stimulation to correspond to slow waves detected based on the adjusted criteria. The system is configured to adjust slow wave detection criteria to enhance detection of slow waves in a subject. Slow wave detection using adjustable slow wave detection criteria produces more stimulation relative to prior art systems because more individual stimuli are provided if more slow waves are detected. In some embodiments, the system includes one or more of a sensory stimulator, a sensor, a processor, electronic storage, a user interface, and/or other components.Type: GrantFiled: December 11, 2015Date of Patent: February 4, 2020Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Gary Nelson Garcia Molina, Anandi Mahadevan, Jesse Salazar, Surya Subrahmanya Sreeram Vissapragada Venkata Satya, John Gerthoffer
