The bases for the remote identification are (1) the comingling of (A) biologic identification information of the person linked to the stimulating device, and (B) information pertaining to a physiologic parameter (e.g. heart rate information) of that person, and (2) the modulation of the physiologic parameter by external information. Embodiments of the invention in which the stimulating device is external to the person are possible. By utilizing the apparatus providing for the remote identification of a person plus stimulating device, one aspect of secure communication—that based on reliable mutual identification of each participant in a communication—is achieved.Type: GrantFiled: August 3, 2015Date of Patent: July 20, 2021Inventor: Jeffrey A.

Patent number: 11058360Abstract: It is possible to measure a pulse rate correctly, when a body moves. A frequency analysis unit 13 generates a pulse wave frequency signal by converting pulse wave detection signals detected by a light sensor 20 into a frequency domain signal from time domain signals. A body motion level determination unit 14 determines a body motion level of a subject based on acceleration detection signals output by an accelerometer 21. A peak detection unit 15 detects a peak of spectrum intensity in the pulse wave frequency signal within a peak searching range, which varies depending on the determined body motion level. A pulse calculation processing unit 16 generates pulse information based on a frequency position of the peak detected by the peak detection unit 15.Type: GrantFiled: February 13, 2018Date of Patent: July 13, 2021Assignee: RENESAS ELECTRONICS CORPORATIONInventor: Masaki Jinnouchi

Patent number: 11051760Abstract: The present invention relates to a wearable device for healthcare and method for using the device. More specifically, the wearable device is worn on a finger for measuring the health data of the user, selected from one or more of heart rate, blood oxygen saturation, heart rate variability. Based on the measured data, the sleep quality can be monitored and recorded. Disorders such as obstructive sleep apnea (OSA), can be detected. The wearable device may include an optical sensor coupled with or embedded in a main body including a visible light emitter, an IR light emitter and a light detector being arranged along a longitudinal direction of the finger. During operation of the wearable device, the heart rate is monitored based on a detected light signal. When the heart rate is higher than an adaptive threshold, both heart rate and blood oxygen saturation are monitored.Type: GrantFiled: May 9, 2017Date of Patent: July 6, 2021Assignee: Belun Technology Company LimitedInventors: Hung Tat Chen, Kwan Wai To, Wenbo Gu

Patent number: 11046272Abstract: A method for enabling a driving assistance function after an accident of a vehicle. The method initially including a reading-in step, in which at least one crash signal, as well as sensor data of at least one vehicle sensor and/or actuator data of at least one vehicle actuator, are read in. The reading-in step is executed while the vehicle is driven with the driving assistance function switched off. The method further includes processing the read-in sensor data and/or actuator data to determine a deviation from expected sensor data and/or expected actuator data; the processing then being carried out, if the crash signal signals an accident that has occurred. The method includes enabling the driving assistance function and/or the vehicle actuator, if the sensor data and/or the actuator data fulfill an enabling criterion within a predetermined time window and/or within a predetermined travel route of the vehicle.Type: GrantFiled: July 17, 2019Date of Patent: June 29, 2021Assignee: Robert Bosch GmbHInventor: Johannes Ludwig Foltin

Patent number: 11033241Abstract: Pulse oximeter systems are described that detect an oxygen level of a user and/or monitor a user's heart rate. The pulse oximeter systems are configured to provide an alert when a user's detected oxygen level decreases below an established oxygen level, and/or when a user's heart rate decreases below a lower threshold value and/or increases above an upper threshold value. For example, an alert may be provided when a user's detected oxygen level decreases by more than about five percent (5%) of an established oxygen level. In some instances, an operator can set a level at which an alert will be provided.Type: GrantFiled: August 30, 2018Date of Patent: June 15, 2021Inventor: Mollie Evans
