Patent number: 10687755Abstract: A wearable physiological monitoring device is provided. The wearable physiological monitoring device includes a wearable object, a sensing module and a processing module. The sensing module is disposed on the wearable object and is configured to stretch based on a local displacement of target organ of the under-test person contacted by the wearable object to generate a change of a sensing value thereof. The processing module is configured to calculate a physiological changing mode that includes physiological information and occurrence time information based on the change of the sensing value. The physiological information includes a number, duration, a degree or a combination of the above of the stretching of the wearable object to determine the health condition of the under-test person.Type: GrantFiled: January 18, 2018Date of Patent: June 23, 2020Assignee: MedicusTek Inc.Inventors: Chung-Cheng Wang, Chia-Ming Hsu, Yu-Chun Hsu, Yi-Yuan Chen

Patent number: 10638217Abstract: An audio appliance includes a microphone transducer having an acoustically sensitive region to convert incident acoustic energy to a corresponding output signal and a barometric transducer having a pressure-responsive region to convert an ambient pressure to a corresponding output signal. The audio appliance also has an acoustic housing defining a chamber to fluidly couple the microphone transducer with the barometric transducer, together with a processor and a memory containing instructions. The instructions, when executed by the processor, cause the audio appliance to determine a presence or an absence of an ambient impairment to the microphone transducer based at least in part on the output signal from the barometric transducer. Responsive to a determined presence of an ambient impairment to the microphone transducer, the instructions, when executed by the processor, cause the audio appliance to mitigate effects of the ambient impairment.Type: GrantFiled: November 5, 2018Date of Patent: April 28, 2020Assignee: Apple Inc.Inventors: Kang Hou, Guohua Sun, Xiang Zhou, Yu-Chun Hsu, Junye Wang
