  • Publication number: 20240427746
    Abstract: A testing system for sensor data of a monitoring system including a server and multiple sensors is disclosed. The server includes a data pre-process module, a value classifying-computing module, and a value comparing module. The data pre-process module performs a data cleaning procedure to sensor data of the multiple sensors to generate multiple cleaned data. The value classifying-computing module computes a difference-value combination of multiple cleaned data of every two sensors in a designated order-direction. The value comparing module subtracts a measuring-accuracy value from every difference-value of each difference-value combination to obtain multiple second difference-value combinations, computes a first feature value of each second difference-value combination, and records a label to two sensors corresponding to one of the second difference-value combinations when a p-value corresponding to the first feature value of the second difference-value combination is determined to be less than a threshold.

  • Publication number: 20240395068
    Abstract: An image processing method for human body posture transformation, which is executed by an electronic device reading an executable code to identify a preset object using artificial intelligence, and performing image processing to capture target postures of the preset object. The method includes the steps of identifying an object, detecting postures, and capturing target postures. The steps involve detecting the preset object undergoing transformation between different postures within a target duration. A capture requirement is met when each posture is visible for a posture visibleness duration and reaches a duration threshold. A target posture transformation video which lasts for a segment duration is captured from an initial image and uploaded to the cloud for storage. An electronic device for human body posture transformation image processing, a terminal device in communication connection with the electronic device, and a non-transient computer-readable recording medium are further provided.

  • Patent number: 11786676
    Abstract: A method is described for supplying a metered amount of a liquid medicament to an aerosolizing device. The method utilizes a dispenser comprising an elongate dispenser body having a proximal end and a tip at a distal end through which a liquid medicament is dispensed. The dispenser further comprises a dispensing mechanism that operates to dispense a metered quantity of the liquid medicament from the tip each time the dispenser body is compressed. The dispenser is grasped with one hand such that the fingers wrap around the dispenser body, with the thumb closest to the proximal end and the last finger closest to the tip. The tip is inserted into an opening of an inhaler and the elongate body is forced toward the tip to cause the dispenser body to compress, thereby operating the dispensing mechanism and causing a metered quantity of the liquid medicament to eject into the inhaler.
