Abstract: This application provides a blood pressure measurement method for a wearable device and a wearable device, so as to improve measurement accuracy of a blood pressure value. The wearable device includes a pressure transducer (PT) and a photoplethysmography (PPG) module. The PT and the PPG module are deployed at a target position of the wearable device. The target position includes a position for contacting a wearer when the wearable device is in a worn state. The method includes: obtaining a pressure value collected by the PT; obtaining a PPG signal collected by the PPG module; and determining a blood pressure value of the wearer based on the pressure value and the PPG signal.

Abstract: A Bluetooth communication method is suitable for a remote controller device. The remote controller device is configured to be Bluetooth-paired with a host terminal. The Bluetooth communication method includes following steps. In a lasting duration since the remote controller device resumes from a power-off mode into a power-on mode and a Bluetooth connection is not yet re-established between the remote controller device and the host terminal, key-input information generated by the remote controller device is temporarily recorded in a buffer memory of the remote controller device. The key-input information temporarily recorded in the buffer memory is attached to a payload of a re-connection advertising packet. The re-connection advertising packet is transmitted, and the re-connection advertising packet is configured to trigger re-establishing of the Bluetooth connection between the remote controller device and the host terminal.

Abstract: This application provides a blood pressure measurement method of a wearable device, and a wearable device. The method provided includes: emitting an optical signal through a first region of a display screen; converting, into a first PPG signal, the optical signal received by the PD; emitting the optical signal through a second region of the display screen if the first PPG signal does not satisfy a signal quality requirement, where the second region and the first region are different in at least one of the following features: a position, luminance, an area size, or a shape on the display screen; converting, into a second PPG signal, the optical signal received by the PD; obtaining a pressure value collected by the PT when the second PPG signal satisfies the signal quality requirement; and determining a blood pressure value of a wearer based on the pressure value and the second PPG signal.

Abstract: Described herein is an apparatus (a flexible pulsation sensor (FPS) device) that provides wireless monitoring capability. The FPS device includes a FPS configured to wrap around a measurement target of a conduit, such as a synthetic vascular graft or a vessel of a patient. The FPS device also includes a flexible circuit board fitting including circuit elements. The circuit elements can include a pressure sensor that collects data related to displacement of the FPS related to a pressure of and/or within the measurement target; and a wireless transmitter that transmits the data related to the pressure of and/or within the measurement target wirelessly to an external device.
