  • Publication number: 20240077392
    Abstract: According to the present disclosure, a measuring method of liquid mixture purity includes steps as follows. A storage tank is provided, wherein the storage tank is configured for storing a liquid mixture including formic acid and water. A calculating unit is provided, wherein a plurality of formic acid purity values are saved in the calculating unit. A pressure-decreasing and heating step is performed by reducing a pressure of the storage tank and heating the storage tank. A measuring step is performed by measuring in the inner space of the storage tank to obtain a pressure value, and measuring the liquid mixture simultaneously to obtain a temperature value. A calculating step is performed by inputting the pressure value and the temperature value into the calculating unit, wherein the calculating unit outputs one of the formic acid purity values corresponding thereto.

  • Publication number: 20230329639
    Abstract: A finger-worn sensing device includes a measurement-device body and a finger-worn structure. The finger-worn structure includes a carrying base on which the measurement-device body can be detachably mounted. The finger-worn structure also includes a first elastic band and a second elastic band, which extend from opposite sides of the carrying base and which overlap each other under the carrying base to form an annular space for the user's finger. The first elastic band has a first free end. The second elastic band has a second free end. The first free end is closer to the annular space than the second free end. A light emitter and a light receiver are located on the inner walls of the first and second elastic bands, respectively. The light emitter and the light receiver are arranged opposite each other so that they can optically sense physiological readings from the finger.

  • Publication number: 20230166943
    Abstract: A non-contact elevator control system having a control panel with multiple buttons, an image processor, a first and a second camera module, wherein the first and second camera modules are arranged at two adjacent corners of the control panel, is disclosed. When an object enters a detection range, the image processor obtains a first imaging position of the object based on a first image taken by the first camera module and a second imaging position of the object based on a second image taken by the second camera module. The image processor calculates the corresponding position of the object in the control panel according to the first and the second imaging positions, and the relative position information of the first and second imaging positions with respect to the first and second camera modules. The image processor triggers a corresponding button in the control panel based on the position.
