Patent number: 11696693Abstract: A wearable device in the form of a tee-shirt is described. The sleeves of the tee-shirt having an electrocardiogram (ECG) sensor, a photoplethysmogram (PPG) sensor or a ballistocardiogram (BCG) sensor for monitoring the pulse of a person wearing the tee-shirt. The tee-shirt makes possible the comparison of the pulses down the two arms. The pulse-transit-time, pulse amplitude, pulse spread and pulse shape may be compared to observe any difference between the left and right sides of the person.Type: GrantFiled: June 20, 2018Date of Patent: July 11, 2023Assignee: WELL BEING DIGITAL LIMITEDInventor: Ming Yip Wallace Wong

Patent number: 11653846Abstract: A device comprising a piece of planar substrate embedded with two sensors and two emitters. The substrate has a generally planar surface for application onto the wearer's body part. The emitters and sensors are shown to be arranged in such a way that no subset of any two emitters and one sensor, or subset of any two emitters and one sensor, forms a straight line, which prevents the two sensors from detecting the same noise caused by the same wearer movements.Type: GrantFiled: June 30, 2020Date of Patent: May 23, 2023Assignee: WELL BEING DIGITAL LIMITEDInventors: Ming Yip Wallace Wong, Chor Tin Ma

Patent number: 11070550Abstract: A device having a fingerprint reader and a first heart rate monitor which are co-located such that a person's heart rate is obtained at the same time as this fingerprint. The device is integral to yet another heart rate monitor for monitoring the performance of the person in exercise. The readings of the other heart rate monitor correlates to the readings of the first heart rate monitor if the person whose fingerprint is read is the same person wearing the second heart rate monitor, in which case the fingerprint is deemed acceptable for identifying the person. Other biometric identification besides fingerprint can be used such as iris recognition.Type: GrantFiled: January 24, 2018Date of Patent: July 20, 2021Assignee: WELL BEING DIGITAL LIMITEDInventors: Juergen Harald Rahmel, Wong Ming Yip Wallace

Patent number: 10512819Abstract: A gait monitor 100 is disclosed which has a pair of movement sensors 501, 503 configured to be placed on either side of a user's head, preferably secured in the ears. Therefore, the movement sensors 501, 503 are each placed on both sides of the user's body but in equal distance to the midsagittal plane of the user and can monitor the gait of the user without need of any movement sensor centrally aligned in the midsagittal plane. Furthermore, the gait monitor 100 is able to determine if the steps of the user strikes the ground in a heel strike or forefoot strike in order to help the user improve his running efficiency.Type: GrantFiled: August 18, 2015Date of Patent: December 24, 2019Assignee: Well Being Digital LimitedInventors: Ping Kow, Ming Yip Wallace Wong

Publication number: 20190282105Abstract: A method, and a related device, for obtaining the blood pressure of a person. The method comprising steps of providing a light source (101), and an optical sensor (103) configured to detect light from the light source which has propagated through the wrist of a wearer of the device. The amount of light propagating through the wrist depends on the amount of blood in the wrist. Blood pressure is then observed by monitoring the difference in the amplitude of blood pulsation within the wrist when the wrist is lifted above heart level, and when the wrist is lowered below heart level.Type: ApplicationFiled: April 19, 2017Publication date: September 19, 2019Applicant: Well Being Digital LimitedInventors: Ming Yip Wallace Wong, Chor Tin Ma

Patent number: 10314499Abstract: A device for monitoring heart rate or blood oxygen level during exercise is disclosed having sensors and emitters, wherein the sensors are used to monitor transmission from each of the emitters in turn. This provides a possibility that a smaller device can be provided since less sensors and emitters can be used while obtaining more number of observations. In some embodiments, the repeated use of sensors with different emitters introduces redundancy into the device so that the device is more robust and may function even in the event that one or two of the emitters and sensors have broken down.Type: GrantFiled: July 22, 2014Date of Patent: June 11, 2019Assignee: WELL BEING DIGITAL LIMITEDInventors: Ming Yip Wallace Wong, Chor Tin Ma

Patent number: 9924259Abstract: An earplug-type earphone is disclosed including: an earplug (10) for producing sound and an elastic support (30). The earplug (10) includes a front housing (200) and a rear housing (500) connected in that order. The elastic support (30) is positioned on an outer side of the rear housing (500). When the earplug (10) is inserted in the external auditory canal, the elastic support (30) is pressed and deformed and then applies resilience to the helix, by which the earplug can be stably positioned in the external auditory canal.Type: GrantFiled: May 26, 2016Date of Patent: March 20, 2018Assignee: Well Being Digital LimitedInventors: Guoqiang Liao, Ming Yip Wong, Chor Tin Ma

Patent number: 9801554Abstract: A noninvasive light sensor for detecting heart beat signals has a circular support member engageable circumferentially with a body part of a person. There are a plurality of light emitters and light detectors located around a circumference of the circular support member for respectively emitting light signals into different areas of tissue surrounding the body part, and receiving reflected light signals from the different areas of tissue surrounding the body part.Type: GrantFiled: January 28, 2015Date of Patent: October 31, 2017Assignee: Well Being Digital LimitedInventors: Chor Tin Ma, Kai Kin Chan, Ming Yip Wong, Kai Wai Yeung, Fo Chau
