  • Publication number: 20240130676
    Abstract: A method and a device of detecting a living tissue element and a wearable apparatus are provided. The method includes: irradiating a detection region with incident light, where the incident light passes through the detection region to form exit light exited from at least one exit position; obtaining a light intensity value corresponding to each beam of the exit light acquired by M photosensitive surfaces, to obtain T output light intensities, where each output light intensity is obtained by processing the light intensity value of the exit light acquired by one or more photosensitive surfaces, and each photosensitive surface is used to acquire the light intensity value of the exit light exited from the exit position within a predetermined anti-jitter range corresponding to the photosensitive surface, 1?T?M; and determining a concentration of at least one detected tissue element according to at least one output light intensity.

  • Publication number: 20240036080
    Abstract: Disclosed are an analog quantity acquisition method and apparatus. An acquisition circuit with a zero flux current transformer is first used to acquire a current signal, where the acquisition circuit with the zero flux current transformer includes the zero flux current transformer, a compensating winding, and a dynamic detection unit, and the compensating winding generates a reverse excitation potential to counteract an excitation current and eliminate impacts of a ratio error and a phase angle error on accuracy. A multi-segment amplification circuit is used to perform segmented amplification on different ranges of the current signal, and full-range current acquisition is achieved by using different amplification circuits. An analog-to-digital converter chip is used to convert an amplified current signal into a digital signal. The acquisition circuit with the zero flux current transformer is used to eliminate the impacts of the ratio error and the phase angle error on the measurement accuracy.
