This invention provides a heart rate information acquisition device that can select the appropriate signal from multiple signals to obtain highly accurate heart rate information. [Solution] A heart rate information acquisition device for acquiring heart rate information of a subject lying in bed comprises: a signal acquisition unit that acquires a plurality of signals, each containing a component that fluctuates according to the subject's heart rate; a signal selection unit that selects an information acquisition signal from the plurality of signals to be used for acquiring the heart rate information based on the kurtosis of each of the plurality of signals; and a heart rate information acquisition unit that acquires the subject's heart rate information based on the information acquisition signal.

This invention relates to the field of data monitoring technology, specifically to a method for monitoring the air pressure stability of an anti-decubitus air mattress. The method involves: obtaining periodic characteristic values ​​based on the air pressure change characteristics of the air chambers; obtaining a historical period range based on all periodic characteristic values; obtaining a fluctuation reference value based on the air pressure fluctuation characteristics within the historical period range; preliminarily judging the air pressure stability of the air mattress based on the air pressure fluctuation characteristics and fluctuation reference value of the current monitoring period; obtaining an average pressure difference based on the air pressure difference characteristics of different air chambers; obtaining the degree of difference based on the average pressure difference between any time in the current monitoring period and any historical reference time; obtaining the degree of positional change based on the user's heart rate fluctuation characteristics and acceleration fluctuation characteristics; and obtaining a correlation degree between the degree of difference and the degree of positional change. This invention obtains air pressure stability characteristic values ​​based on the correlation degree and the degree of difference and monitors the air pressure of the air mattress, improving monitoring accuracy.

1. Name of the product in this design: Heart rate display area for a graphical user interface of a song playback page in an electronic device. 2. Purpose of this design: An electronic device. 3. The key design features of this product are: the parts in the graphical user interface, and the parts not marked with dotted lines are the parts for which protection is required. 4. The image or photograph that best illustrates the design's key points: Design 2 main view. 5. Design 2 is designated as the basic design. 6. Purpose of the graphical user interface: The overall appearance design of the interface is used to display song information and related playback control buttons, and to observe heart rate changes (such as heartbeat animation, heart rate value, and heart rate fluctuation frequency) when playing songs. The partial appearance design of the interface is used to observe heart rate changes (such as heartbeat animation, heart rate value, and heart rate fluctuation frequency) when playing songs. 7. Human-computer interaction method of graphical user interface: In the main view of Design 1, the heartbeat animation, heart rate value and heart rate fluctuation frequency are displayed at the top of the interface, which can change according to the user's status (such as listening to music, exercise status, etc.). The human-computer interaction methods of Designs 2 to 6 are the same as those of Design 1, but the heartbeat animations are different for different heart rate values. In the main view of Design 7, the heartbeat animation and heart rate value are displayed at the top of the interface, which can change according to the user's status (such as listening experience, exercise status, etc.). In the main view of Design 8, the heart rate value and heart rate fluctuation frequency are displayed at the top of the interface, which can change according to the user's status (such as listening to music, exercise status, etc.).
